conversion loss.
When two or more modes travel together down the
waveguide, the center of the microwave beam will, in
general, be offset from the axis. Also, when the modes
reach the end of the waveguide, they will radiate into spacewith a tilt angle. The offset and tilt angle may be a problem
in the launcher / antenna system for plasma heating andcurrent drive. The case of two modes traveling in the
waveguide has been analyzed in a recent paper by Kowalski
et al. [2]. The paper shows that the offset varies with
distance along the waveguide as a cosine wave, while thetilt angle varies as a sine - that is, the tilt angle is ninety
degrees out of phase with the offset. With proper
normalization, the square of the offset and the square of thetilt angle can be added to express a conservation theorem[2]. The variation of offset and tilt angle repeats with
distance down the waveguide at the beat wavelength of thetwo modes. For the present case, we have most of thepower in two modes - the HE11 mode and the LP11 mode but there is still significant power in a series of higher
modes. For the present case, the experimental values of thetilt angle and offset are plotted vs. extended waveguidelength in Figs. 2 and 3 respectively. We also show fits tothe tilt angle and offset using sine/cosine functions with aperiodicity of 5 meters, which is the beat wavelength of thetwo major modes (LP01 and LP11). The measured values oftilt and offset agree well with the theoretical sine/cosine
curve fits. We see from these results that as the microwaves
propagate down the waveguide, they will always have someamount of either tilt or offset or both.

The 170 GHz transmission line (TL) for the electron
cyclotron heating and current drive (EC H&CD) system in
ITER requires more than 90% power transmission
efficiency from the gyrotrons to the plasma using about 100
m length corrugated waveguides. For high transmission
efficiency, the good purity of HE11 mode is necessary(95%). In this study, the transmission mode in the 170 GHz
high power long transmission test line for ITER, which
consists of the 63.5 mm corrugated waveguides, wasmeasured and the effect of higher order modes (HOMs) in
ITER’s transmission line is discussed.
The millimeter wave beam was generated by the 170
GHz high power gyrotron [1] and coupled into thecorrugated waveguide through the Matching Optics Unit
(MOU) constructed with two phase correcting mirrors. The
power is transmitted to the dummy load. Two high powertransmission test lines were prepared. One is a short range
TL (7 m) and the other is a long range TL (40 m) as shownin Fig. 1. The direction of the RF power is selected by the
waveguide switch. The TL system has 7 miter bends
including the waveguide switch in the long range TL.

Using measured IR patterns, the mode content was
retrieved using the MIT codes. A set of linearly polarized(LP) modes is used. In this analysis, the four LP modes are:fundamental mode LP01 (HE11), LP11 (even and odd), andLP02 (HE12) modes. There was a small difference in themode content between long TL and short TL. This indicatesthat the mixture of HE11 and LP11 modes could be

JIFT Workshops on Theoretical Analyses in Helical Plasmas
Category: JIFT
Year/Number: 2004-JF1-01
Names: D. Monticello (PPPL), N. Nakajima (NIFS)
Dr. Monticello and Dr. Nakajima organized a series of
two workshops on theoretical physics issues in 3D toroidal
magnetic confinement systems.
1. First workshop (Princeton, 2002)
A workshop entitled “Theoretical Consideration on
Helical Plasmas” organized by Dr. Nakajima (NIFS) and
Dr. Monticello (PPPL) was held in Princeton on November
18-21, 2002. Sixteen talks were presented. The talks
focused mostly on stellarator experiments that wereoperating at the time of the conference (LHD, Heliotron-J,
W7-AS, and HSX) and on proposed experiments such as
QPS, W7-X, and NCSX. A synopsis of all the talks was
prepared by Nakajima and Monticello and published in the
May 2003 edition of Stellarator News [1]. The talks wereposted on the workshop website [2]. Several results fromthis workshop are shown in Figs. 1-3 here.

2. Second workshop (Kyoto, 2005)
A follow-on workshop, entitled “Progress oftheoretical analyses in three dimensional configurations,”
with the same two organizers, was held in Kyoto on
January 25-27, 2005. There were five participants from the
US and seventeen from Japan. The US representatives were
A. Boozer (Columbia), C. Hegna (Wisconsin), L.
Sugiyama (MIT), A. Ware (Montana), and D. Monticello(PPPL). The talks covered a wide range of stellarator
physics, including equilibrium, MHD stability, kinetic
stability, pellet ablation, and edge physics. Probably mostinteresting were the details of theoretical analyses of theexperiments on the Large Helical Device (NIFS) thatattained plasma beta of 4.2%. A report on the workshop,with a synopsis by the US participants, was presented to
the US stellarator physics community on February 10, 2005,
as part of the National Stellarator Theory seminar series.
The talks were posted on the workshop website [3]. This
information was also announced in Stellarator News.

Nakajima (NIFS)(a)Dr. Rewoldt has been involved in three general areasof work for the Joint Institute for Fusion Theory program.
He made many trips to Japan under its auspices. These
areas of research were:(1) Ideal MHD equilibrium and stability analysis ofstellarator/heliotron devices, in particular Heliotron-E,
using the STEP code, a modified version of the PEST code,
which implements the so-called stellarator expansion. This
work was done in collaboration with J.L. Johnson (PPPL),
M. Wakatani and Y. Nakamura (Kyoto University Plasma
Physics Laboratory), and others, over the period from 1985
to 1991.
(2) Linear and quasi-linear gyro-kinetic microinstability analysis of the JT-60U tokamak using the FULL
code, in collaboration with K.W. Hill, W.M. Tang, andothers (PPPL) and H. Shirai, Y. Kishimoto, and manyothers (JAERI). This work involved calculations of linear
growth rates and real frequencies and ratios of quasi-linear
fluxes, using realistic experimental density and temperature
profiles and MHD equilibria, over the period from 1999 to2005.
(3) Linear gyrokinetic micro-instability analysis of the
LHD stellarator using the FULL code, in collaboration with
L.-P. Ku and W.M. Tang (PPPL), W.A. Cooper (CRPPEPFL), and H. Sugama, N. Nakajima, K.Y. Watanabe, S.
Murakami, H. Yamada, and many others (NIFS), over theperiod from 2000 to 2003. In these calculations, modes
such as trapped-electron modes and ion temperature
gradient modes can be unstable, with contributions fromboth toroidal curvature and helical curvature to resonancesof both toroidally trapped and helically trapped electrons.
Numerous publications resulted from these joint
collaborations. Selected papers are listed below [1-5].

64Effect of Resistive Wall on External Kink Modes

Category: JIFT
Year/Number: 2004-JF1-06
Names: M.S. Chu (GA), K. Ichiguchi (NIFS)
Dr. Chu from General Atomics spent three months at
NIFS as the JIFT Visiting Professor (September 1–
November 31, 2004). During this time, he performed
research in collaboration with Dr. K. Ichiguchi concerning
the possibility of resistive wall modes in 3D magnetic
confinement configurations.
The external kink mode is one of the most serious
instabilities that affect plasma confinement. Its growth rateis usually fast, outside the range of feasibility for plasma
control. The external kink mode can be stabilized by thepresence of a nearby perfect conducting wall. When theresistivity of the wall is taken into account, the externalkink mode is changed into the resistive wall mode (RWM).
Its growth rate then reduces to the inverse of the flux
diffusion time through the resistive wall. The RWM with
its slower growth rate can be stabilized either by plasma
rotation or magnetic feedback. In configurations without
toroidal symmetry, plasma rotation is relatively small andnot expected to stabilize the RWM. Therefore, magnetic
feedback must be relied upon to stabilize the RWM in nonaxisymmetric configurations. As preparation for the designfor feedback control of the RWM, the growth rate of the
RWM in these configurations was investigated.
A method was formulated for the systematiccomputation of the growth rate of the RWM in weakly
unstable 3D configurations by using results from ideal
stability codes. It was shown that the growth rate of the
RWM is given, approximately, by the rate at which theavailable free energy for the ideal external kink mode (withthe wall at infinity) can be dissipated by the resistive wall.
By relying on the concepts of energy and dissipation, themethod is readily connected with other MHD codes andprovides an independent and useful method of studying thephysics of RWM.
This formulation was demonstrated by coupling to theideal MHD code KSTEP to study the stability of the RWM
in LHD plasmas. It is found that in terms of plasma current,a very limited range of the plasma equilibria can have its
external kink mode affected by the presence of the resistive
wall, i.e., the plasma quickly transits from being stable withrespect to the external kink mode to being unstable evenwhen the wall is upon on the plasma. Nevertheless, it wasdemonstrated that the proposed method can be used toevaluate the growth rate of the RWM in any 3D
configurations readily. The growth rate in the advanced
stellarators can also be calculated by employing full 3D
codes such as CAS3D and TERPSICHORE instead of the
KSTEP code.

Analysis of Axisymmetric Equilibria with Flows in Non-Ideal Fluid Models

2. High-Beta Axisymmetric Equilibria with Flow
The second part of the work was devoted to reducedMHD models with high-beta and large-aspect-ratioorderings [2]. In improved confinement modes ofmagnetically confined plasmas where high-beta is achieved,
equilibrium flows play important roles like the suppressionof instability and turbulent transport. At the sharp boundaryof a well-confined region, the scale lengths characteristic of
microscopic effects not included in single-fluid
magnetohydrodynamics (MHD) cannot be neglected. Small
scale effects on flowing equilibria due to the Hall current
have been studied with two-fluid or Hall MHD models.
However, these models are consistent with kinetic theory
only for cold ions [1]. In order to include the hot ion effects
that are relevant to fusion plasmas, an extension of themodel is necessary. A consistent treatment of hot ions in a
two-fluid framework must include the ion gyroviscosityand other finite Larmor radius (FLR) effects. A two-fluid
equilibrium system including Hall and finite ion Larmor
radius effects was derived for flows comparable to thepoloidal Alfven velocity, showing that the ion
gyroviscosity produces a shift of the Alfven singularity. A
single-fluid system was derived for flows comparable tothe poloidal sound velocity, a case that requires keeping
higher-order terms in the aspect ratio expansion before thesingular velocity points can be shown. Since theformulation of higher-order equations is involved, here we
restricted our analysis of the poloidal-sonic flow to thesingle-fluid case, planning to extend our present resultswith the inclusion of two-fluid, hot ion effects in future
work. The singularity at a poloidal flow velocity equal tothe poloidal sound velocity was recovered in the higher
order equations. The orderings in this study provide thesimplest models that include ion FLR effects on toroidal
equilibria with flow. As such, they should be justconsidered as convenient working hypotheses that allow
our analytic study of such effects. The resulting equations
can be easily solved numerically to yield flowing equilibria
without singularity and their solutions can be used as initialstates or for comparison with saturated states of reduced
model nonlinear simulations.

1. Ellipticity of Axisymmetry Equilibria with Flow and
Pressure Anisotropy
The first part of the work was based on a Hall-MHD
model with cold ions, zero-mass electrons and finite
electron pressure anisotropy [1]. This model included aclosure consistent with dynamical evolution equations forthe parallel heat fluxes and yielded a homogeneous plasma
dispersion relation identical to the one derived from kinetic
theory. The ellipticity criteria for the partial differential
equations of axisymmetric single-fluid and Hall
magnetohydrodynamic (MHD) equilibria with flow andpressure anisotropy are investigated. In the limit ofvanishing ion skin depth, it reduces to a single-fluid modelwith anisotropic pressure, which predicts mirror andfirehose instability thresholds in agreement with kinetic
theory. In the single-fluid description of plasmas,
axisymmetric toroidal equilibria with flow are obtained bysolving the so-called generalized Grad-Shafranov (GS)equation and the Bernoulli law. In the absence of poloidal
flow, the equilibrium is elliptic if the kinetic stability
conditions for the firehose and mirror modes are satisfied.
Conditions for ellipticity of the axisymmetric toroidal
equilibria with flows were derived and shown to be related
to the velocities of waves in the kinetic-consistentdispersion relation. These conditions are different fromthose for the double-adiabatic Chew-Goldberger-Low
model. For anisotropic Hall MHD, a set of anisotropicpressure equilibrium equations has been derived. It consistsof the coupled GS equations for the magnetic flux and theion stream function and the Bernoulli law for ions. Unlike
the isotropic case, in the presence of pressure anisotropy,
the characteristic determinants for each GS equation arecoupled and cannot be examined their ellipticity separately.
One can find the conditions for ellipticity of such systems
involving higher order derivatives by examining theexistence of wave type solutions, a method also applicable
to second order differential equations. If we consider awave propagating in one-dimensional space and time andhaving discontinuity across the wave front, ellipticity of thecoupled GS equations requires the non-existence of realvalues of the velocity of the wave front. A sufficientcondition for ellipticity was obtained that corresponds to apoloidal flow velocity slightly smaller than the soundvelocity.

JIFT Workshop on Gyrokinetic Simulation of Plasma Transport

Category: JIFT
Year/Number: 2007-JF1-1
Names: T. S. Hahm (PPPL), H. Sugama (NIFS)
This workshop was held at the High Temperature
Plasma Center, Kashiwa Campus, The University of Tokyo,
September 24 and 25, 2007.
The workshop consisted of 4 sessions: (I) Recent
Progress in Gyrokinetic Simulation, (II) Theory andExperiments on Momentum Transport, (III) Theory and
Simulation of Electric Fields and Flows, and (IV) MultiScale Physics, New Fluid Simulation.
In addition, there was a special lecture entitled“Plasma Waves and Instabilities in Shear Flow–A Frontierof Functional Analysis beyond von Neumann’s Theorem.”Talks were presented by 11 scientists from Japan, 2 fromUS, and 2 from EU. Recent results from theoretical andsimulation studies about plasma transport based on
gyrokinetic and gyrofluid models were reported.
Comparative studies of theoretical modeling andexperimental results of toroidal momentum transport intokamaks and helical systems were made. Also, topics suchas zonal flows, geodesic acoustic modes, and multi-scaleinteractions in ion temperature gradient (ITG) turbulence
were discussed.
Several papers that were subsequently publishedacknowledged simulating scientific exchanges during thisworkshop. One such paper [1] presented a refined
formulation of the gyrokinetic equations for plasmas withlarge flow shears caused by an equilibrium electric field.
Through the choice of a more suitable equilibrium drift
velocity for the reference frame of a charge particle, theaccuracy of the gyrokinetic equations can be significantly
improved. Another paper [2] showed the derivation of anenergy conserving set consisting of the fully
electromagnetic nonlinear gyrokinetic Vlasov equation andMaxwell’s equations, where this set of equations isapplicable both to L-mode turbulence with large amplitude
and to H-mode turbulence in the present of large ExB shear.
A third paper [3] described how plasma parameter scans—such as the plasma current, neutral beam heating power,
and electron density—had been used to obtain properties of
the toroidal momentum diffusivity and the convection
velocity in H-mode plasmas in the JT-69U experimental
facility.

Reduced Nonlinear Dynamics for Turbulent Transport
In Toroidal Confinement Devices
Category: JIFT
Year/Number: 2008-JF1-12
Names: W. Horton (IFS Texas), H. Sugama (NIFS),
T.-H. Watanabe (NIFS)
In about 2000, we became interested in new techniques
to analyze ion temperature gradient (ITG) driven
turbulence. For the infinite chain of linked fluid transport
equations, we wanted to find a fluid closure that would
reproduce the most important aspects of the full gyrokinetic
equations. In the 1990s, we had completed a series ofstudies of fluid turbulence theory and simulations for the
resistive-g mode and the Hasegawa–Wakatani drift wave
model. Our fluid simulations showed that nonlinear
interactions in the unstable spectrum produced sheared
azimuthal ExB flows and an oscillation in the parallel
thermal flux. The question was how to find an accurate
ITG gyrofluid model.
We wanted a new closure procedure with parallel heat
fluxes that would give accurate nonlinear energy
conservation laws and correct entropy production functions.
Using the unstable Vlasov-Poisson ion temperature
gradient (ITG) modes, we searched for closures that
reproduced the unstable and stable spectra. This implied
preserving the time-reversal symmetry of the collisionless
kinetic equation. After studying the closure of Mattor andParker (1997), we eventually found a closure that preserves
time reversibility and whose unstable-stable spectrum
agrees fairly well with that from the plasma dispersion
function of the exact kinetic equation. The key point is thatthe new non-dissipative collisionless closure method
enabled the very accurate calculations of the parallel
thermal flux driven by temperature fluctuations that are
required.
Our result [1] led to a series of simulations andderivations of reduced gyrofluid equations [2]. The mostrecent concerned zonal flows driven by turbulence [3],simulated with the GKV code.
The GKV code of Sugama and Watanabe is now
widely used for turbulence simulations. It solves for thefluctuation distribution function directly on high-resolution
parallel velocity grids, which allows accurate tracking of
the phase and amplitude of higher order parallel velocity
moments. Comparison with the Hammett-Perkins closure
showed that the GKV solutions reproduce the radial
turbulent thermal flux more accurately.
During Horton’s three-month visit to NIFS in 2007 as
the JIFT Visiting Professor, the GKV code wasbenchmarked on several large-scale parallel computers,
including Ranger at the University of Texas and Blue Geneat ORNL. The code showed good linear scaling with thenumber of processors.
This joint work is continuing. The new closure models
are now being used in the pseudo-spectral simulations with
ion-temperature-gradient and electron-temperature-gradientturbulence gyrofluid models.

MHD equilibrium by a resistive steady state, but we havecome to this conclusion by considering the impact ofchaotic fields on MHD equilibria, and requiring that thepressure be continuous. Since the equilibrium solutions arepathological when the field is chaotic, a nearly-ideal,
resistive steady state equilibrium is the simplest model
capable of computing coherent, self-consistent MHD
equilibria with continuous (and non-fractal) pressure. Work
towards implementing the anisotropic pressure diffusion
into the HINT code has begun. Our approach, which is bothcomputationally efficient and consistent with the structureof the HINT code, is to use locally field aligned
coordinates that separate the large parallel transport fromthe small perpendicular transport, and thus reducs so-called“numerical diffusion.” We hope to present computational
results in the near future.

Dr. Hudson from PPPL spent three months at NIFS as
the JIFT Visiting Professor (summer 2009). During thistime, he performed research in collaboration with Dr. N.
Nakajima concerning how to realistically and efficiently
compute MHD equilibria in the presence of chaotic
magnetic fields.
Analyses of plasma behavior often begin with adescription of the ideal magnetohydrodynamic equilibrium,
this being the simplest model capable of approximating
macroscopic force balance. For perfectly axisymmetrictokamaks this is a comparatively simple task, since a nested,
continuous family of flux surfaces exists, i.e. the field is
integrable. The ideal equilibrium equation can be reduced
to the Grad-Shafranov equation, and equilibria can befound numerically. In contrast, for stellarators andperturbed tokamaks, the magnetic fields are generally nonintegrable and a different approach is required.
Stellarators are designed to have good flux-surfaces,
but without a continuous symmetry, perfectly integrable
fields cannot be achieved. The HINT and HINT2 codesdeveloped at NIFS, and the PIES code developed at PPPL,
seek solutions to the ideal force balance equation instellarator geometry without assuming a nested family offlux surfaces. HINT uses a relaxation algorithm, whereas
PIES is based on an iterative scheme with magnetic
coordinates. However, neither code adequately treats thefractal structure of pressure in a chaotic field.
A generally chaotic field will be a fractal mix of KAM
surfaces, islands, and irregular field lines. Some field lines
trace out structures that are infinitely complex, such as theunstable manifold. Interspersed between these irregularfield-lines are periodic orbits; arbitrarily small, high-orderisland chains; and irrational field-lines, which may or may
not trace out smooth flux surfaces. Generally, there is noregion of space foliated with flux surfaces and magnetic
islands and irregular field-lines will emerge at the infinitely
many rational surfaces that exist between any pair of KAM
surfaces. When the field is chaotic, it is extremely difficult
to calculate the ideal MHD equilibrium.
In ideal force balance, the structure of the pressure istied to the structure of the field. Thus, a continuous,
nontrivial pressure has an uncountable infinity of
discontinuities in the pressure gradient. The equilibrium
solutions are pathological when the fields are chaotic andtherefore unsuitable for numerical calculations.
If the pressure and magnetic field are continuous, theonly nontrivial solutions have an uncountable infinity of
discontinuities in the pressure gradient and current. The
problems arise from the arbitrarily small length scales inthe structure of the field, and the consequence of ideal
force balance that the pressure is constant along the fieldlines. A simple method to ameliorate the singularities is toinclude a small but finite perpendicular diffusion. A self-[1] S. R. Hudson and N. Nakajima, “Pressure, chaotic

Stabilization of Neoclassical Tearing Modes by Electron Cyclotron Current Drive

location were performed in real time [7]. Typical example
is shown in Fig. 2. In the discharge, the beta value wasraised to the no-wall ideal MHD limit by suppressing theonset of an m/n = 2/1 NTM. Soon after the switch-off of the
ECCD, an m/n = 2/1 NTM appeared. This result shows theeffectiveness of the preemptive ECCD.

Neoclassical tearing mode (NTM) is anmagnetohydrodynamic (MHD) instability which appears inhigh-E plasmas with positive magnetic shear (E is the ratioof the plasma pressure to the magnetic pressure). Since theNTMs degrade the plasma confinement through theformation of magnetic islands, stabilization of the NTMs isrequired to sustain a high-E plasma. Localized current driveat the mode rational surface using electron cyclotron (EC)waves, electron cyclotron current drive (ECCD), is
considered to be the most promising method for NTM
stabilization due to the capability of high magnitude ofcurrent drive density and high accuracy of current drive
location.
Both JT-60U and DIII-D devices have the capabilityof detailed investigation on NTM physics because theyequip (a) high-power heating system to obtain a high-beta
plasma, (b) high-power EC wave system to actively
stabilize NTMs, (c) high temporal and spatial resolution
diagnostics to measure and control NTMs and (d) advanced
plasma control system for real-time NTM stabilization. A
number of leading results have been reported from the bothdevices. For example, most recently, NTM stabilization bymodulated ECCD was demonstrated [1, 2]. Against the
backdrop of these results, close research collaboration has
been continued between JT-60U and DIII-D.
It is known that NTM islands have the property of
spontaneous shrinkage at small island width due to several
stabilization effects, and such shrinkage has also been
observed experimentally. Investigation on the island width
at which the spontaneous shrinkage begins, which isreferred to as the marginal island width, is important inestimating the required EC wave power and establishing the
scenario for NTM stabilization. In collaboration withASDEX-U (Max-Planck-Institut für Plasmaphysik,
Germany), DIII-D and JT-60U, the marginal island width
for an m/n = 3/2 NTM was investigated. Here, m and n are
the poloidal and toroidal mode numbers, respectively. It
was found that the marginal island is about twice the ion
banana width (Fig. 1) [3]. In addition, based on the results
and experiences in ASDEX-U, DIII-D and JT-60U,
requirement for real-time NTM stabilization in ITER was
also investigated [4].
Stabilization of NTMs by ECCD is usually achievedby injecting EC waves inside the NTM islands. As a new
strategy, ECCD at the mode rational surface before theNTM onset, what we call preemptive stabilization, wasdeveloped and the effectiveness was successfully
demonstrated in JT-60U [5, 6]. Preemptive stabilization ina higher-E regime was demonstrated in DIII-D withparticipation of JT-60 staffs. Experiments using a newly
developed real-time control system were successfully
conducted, where equilibrium reconstruction with current
density measurement and identification of the mode

High-brightness and low-divergence lithium neutral beam for a Zeeman polarimetry on JT-60U

account because a low divergence angle of the neutral
lithium beam is required in terms of the narrow spectrum of
the beam emission and the high transmission of the long
beam line of 6.5 m. Although the beam energy of 10 keV isrelatively low, an extraction electrode installed in front of
the ion source can produce a large current beam over 10
mA.
The newly-developed ion gun has been operated on atest stand which simulates the diagnostic geometry on JT60U. The ion beam current of 10mA at a beam energy of
10 keV is successfully extracted from the ion source andfocused by Einzel lens. The FWHM (Full Width at Half
Maximum) radius of the ion beam at the neutralizer isabout 9 mm. A sodium vapor neutralizer neutralizes thecollimated ion beam fully at the temperature of 300 oC. The
neutral beam profiles have been measured at two locationsof the beam line at 2.3 m (beam monitor position) and 6.5m (plasma region) from the neutralizer. The HWHM radiusof the neutral beam of 26mm and the equivalent beam
current of 3 mA with the beam divergence angle of 0.2
degree which is the half-angle divergence have beenobtained. Those parameters satisfy the requirements of the
Zeeman polarimetry. Furthermore, a long pulse extraction
with a current of 10 mA and duration of 50 seconds has
been attained [2].
After developing the detectors, the LiBP has been
installed on JT-60U. The LiBP has 20 viewing chords inthe edge region r/a = 0.8 ~ 1.0 with a spatial resolution of 1
cm. Etalon and band-pass filters are applied to separate thepolarized spectrum of the beam emission. In order to tune
the etalon filters, a new technique in which the Doppler
shifted spectrum is varied by sweeping the beam energy
has been developed and has demonstrated the availability[3].
The electron density profiles in the edge region havebeen measured by using the LiBP with a temporal
resolution up to 0.5 ms. In addition, an ELM cycle in casesof type I and grassy ELMs have been observed [4]. The
collapse of density pedestal of grassy ELMs is smaller(<20%) and the radial extent is narrower (ѝ 5 cm) thanthose of type I ELMs (~30%, >15cm). The measurement of
the edge current density has been also achieved by using
the LiBP [3]. Time evolution of the edge current density
profiles have been determined for the current ramp
up/down in the OH plasmas. Moreover, the edge current
density profile having the local peak of 0.15–0.25 MA/m2
at r/a ~ 0.9 has been identified in the H-mode plasma. The
local peak might be caused by the strong pressure gradientin the edge pedestal region.

Lithium beam probes (LiBP) are powerful diagnostic
for pedestal studies since the electron density and the pitch
angle of the magnetic field line in edge plasmas can bemeasured from the beam emission signal and its
polarization angle. In order to measure the edge plasmas
with high-spatial and high-temporal resolutions, highperformance neutral lithium beams are required. In theprevious works on DIII-D, direct measurements of the edge
current density was carried out by use of 30 keV, >10mA
lithium beams [1]. Recently, JT-60U planned to install the
LiBP for the measurement of the edge electron density andcurrent density. For the LiBP on JT-60U, the optimum
beam energy was lower than that for DIII-D because oflower pedestal density. However, the large beam current
was also required to obtain a high S/N ratio. Such beams
are strongly affected by the space charge effects and easy
to spread. Therefore, a high-brightness and low-divergenceneutral lithium beam source with low energy of 10 keV has
been developed on JT-60U.
In order to obtain a large current over 10 mA, athermionic ion source heated by an electron beam has beendeveloped. The diameter of the ion emitter is 50 mm which
is made from porous tungsten with porosity of 30 %. The
porous tungsten disk is mounted on the molybdenum
holder as shown in Fig. 1. The acceleration voltage of 1.5
kV for the electron beam is applied between the disk and atungsten filament behind the disk. The surface temperatureof the disk reaches to 1500 oC with the typical heating
power of 1.3 kW. The extracted ion current can exceed 10
mA in this case. The maximum power of the electron beam
heating is 5 kW which is enough to make E eucryptite(Li 2 OxAl 2 O 3 x2SiO 2 ) soaked in the disk.
The beam optics has been designed after detailed
numerical simulation taking the space charge effects into

Numerical Method for the Stability Analysis of Ideal MHD Modeswith a Wide Range of Toroidal Mode Numbers in Tokamaks

ELM phenomena. For not only the experimental analysis ofexisting devices but also the design of ITER and JT-60SA,
MARG2D realizes the stability analysis of the various
kinds of ideal MHD modes that restrict the beta limit andthe pedestal performance.

In tokamaks, an ideal magnetohydrodynamic(MHD) instability attracts attention as one of key issues fora high performance operation. This is because a low-n
MHD mode often restricts a plasma performance (betalimit), and intermediate / high-n MHD modes sometimes
determine an edge pedestal performance, where n is atoroidal mode number. To identify the stability of theseMHD modes, we have invented the effective numericalmethod for the stability analysis of ideal MHD modes withthe physical model based on the two-dimensional
Newcomb equation in combination with the conventional
compression-less ideal MHD model. The MARG2D code
has been developed based on this numerical method, andrealizes to analyze the stability of ideal MHD modes with awide range of toroidal mode number n [1,2]. In thiscollaboration, we execute the benchmarking test of thisMARG2D code with the DCON code [3] for a low-n modestability analysis, and that with the ELITE code [4,5] for anintermediate / high-n mode analysis.
Figure (a) shows the dependence of the E N limit on
the wall position da. These dependences identified with
MARG2D and DCON are almost identical to each other.
Unfortunately, since the DCON code used in thisbenchmarking (ver. 3.2) cannot output the marginally stableeigenfunction, we cannot compare the radial structure of
the eigenfunction. However, in a up-down symmetricequilibrium, the benchmarking tests between MARG2D
and the ERATOJ code [6] have been executed in Ref. [2],and the radial structures of the marginally stableeigenfunctions have been identified as almost same as eachother.
Figure (b) shows the toroidal mode number ndependence of the growth rate J normalized with thetoroidal Alfv´en frequency on the magnetic axis ZA . The
agreement between MARG2D and ELITE is quite good,
and as shown in Ref. [7], the radial structures of the most
unstable eigenfunction obtained with MARG2D and ELITE
are almost identical to each other. The results of thesebenchmarking tests show the validity of the MARG2D codefor the stability analysis of not only low-n but alsointermediate / high-n MHD modes [7].
With this code, we investigated the MHD stability
property in JT-60SA, the complemented device for ITER
focusing on effect of the plasma shape. These stability
analyses show that the highly shaped plasma designed forachieving high performance discharges in JT-60SA is
suitable for stabilizing not only low toroidal mode number
MHD modes, which restrict the E N limit of discharges, butalso intermediate to high toroidal mode number MHD
modes, which relate to the edge pedestal performance andFig. 1: Dependence of the E N limit on the wall position d/a.
Each dependence of the E N limit restricted by the n =1, 2, 3 MHD modes stability estimated with MARG2D isalmost identical to that calculated with DCON.

Fig. 2: Dependence of J / ZA on n calculated with
MARG2D (solid line) and ELITE (broken line). The
agreement between both codes is quite good.

stabilization of RWM is demonstrated for 50 times theskin time of the first wall. These results indicate that forlarge plasmas such as in future fusion reactors with low
rotation, the requirement of the additional feedback
control system for stabilizing RWM is much reduced.
Around the same time, similar experiments were
performed on DIII-D. High-Ǫ DIII-D experiments with
the new capability of balanced neutral beam injection also
show that the resistive wall mode (RWM) remains stable
when the plasma rotation is lowered to a fraction of a percent of the Alfv´en frequency by reducing the injection ofangular momentum in discharges with minimized
magnetic field errors [7,8]. A toroidal rotation frequencyof less than 10 krad/s at the q = 2 surface corresponding to
0.3% of the inverse of the toroidal Alfve´n time issufficient to sustain the plasma pressure above the ideal
MHD no-wall stability limit (Fig. 1). The low-rotationthreshold is found to be consistent with predictions by akinetic model of RWM damping. Previous DIII-D
experiments yielded a high plasma rotation threshold (oforder a few per cent of the Alfv´en frequency) for RWM
stabilization when resonant magnetic braking was applied
to lower the plasma rotation. They propose that thepreviously observed rotation threshold can be explained as
the entrance into a forbidden band of rotation that resultsfrom torque balance including the resonant field
amplification by the stable RWM.

To realize an economical fusion reactor,
stabilization of the low-n kink-ballooning mode isnecessary: An economical fusion reactor, in its steadystate, relies largely on the spontaneously flowing bootstrap
current for its plasma current that produces the confining
magnetic field, because this can reduce the externallydriven current. But such plasma has generally a hollow
current profile and is susceptible to the low-n kinkballooning mode, which can limit the achievable beta.
The growth rate of the external kink-ballooning mode canbe reduced with a close-fitting conducting wall, and theresulting mode, the so-called resistive-wall mode (RWM),
has a growth time corresponding to the time constant of
the relaxation of the wall current [1]. There are twodifferent procedures for stabilizing RWM. The first is the
feedback control stabilization using externally applied
nonaxisymmetric magnetic fields with coils in order tocompensate for the diffusion of flux [2]. The second isstabilization of RWM by toroidal plasma rotation.
Bondeson and Ward showed that RWM could be fullystabilized with resistive walls when the plasma rotation is
sufficiently large [3]. Both theories and experiments
imply that the critical rotation velocity is around 1% – 2%of the Alfve’n velocity. This estimated critical rotation iscomparable to a predicted toroidal rotation of 2% of the
Alfve’n velocity at plasma center and much larger than
0.3% of that in the peripheral region including the q =integer surface for the ITER advanced scenario. The
most significant problem in the previous experiment is thatinvestigation of the critical rotation is performed withmagnetic braking by adding an asymmetric magnetic field,
the so-called error field. It has been pointed out that theerror field plays a very important role in the destabilizationof RWM and should be substantially reduced near the nowall limit. Since RWM stability itself is affected by
the error field, which is the origin of magnetic braking, weshould not use magnetic braking in the investigation ofcritical rotation.
A very low rotation threshold was obtained in the JT60U in an investigation of the critical rotation forstabilizing RWM by controlling the toroidal plasma
rotation with changing the combination of tangential
neutral beams (NBs) without magnetic braking [4-6]. The
observed critical rotation is Vt~20 km/s and corresponds
to 0.3% of the Alfve’n velocity at the q = 2 surface,much smaller than the previous prediction with magnetic
braking (Fig. 1). This low critical rotation does notincrease as increases toward the ideal wall limit. Also an
ITER relevant low rotation (~0.4% of the Alfve’n velocity)

Irradiation effects on deformation and fracture of reduced activation ferritic steels

R.L.Klueh*, R.E.Stoller*,G.R.Odette**, S.Jitsukawa
JAEA, *ORNL, **UCSBReduced activation ferritic steels (RAFs) are candidate structural
materials for in-vessel components of a DEMO. The service
temperature is expected to range between 300 and 550oC while
14MeV D-T fusion neutron irradiation introduces displacement
damage to 100-150 dpa and damage from transmutation produced
atoms (e.g. He atoms with production rate of 10-15 appmHe/dpa) tocause reductions of elongation, fracture toughness and fatigue life, as
well as dimensional changes by irradiation creep and swelling[1].
Therefore, the DOE-JAEA collaborative experimental programusing HFIR has been conducted to investigate the irradiation
response of RAFs. Japan’s F82H was chosen as a reference heat with
objective of producing an irradiation materials database, while
analyzing deformation and fracture for the modeling of the irradiation
effects. The results indicate that degradation by displacement damage
is manageable for the doses examined [2]. Moreover,tightening/optimization of heat treatment conditions reduced
radiation-induced embrittlement, suggesting the feasibility of RAFs
for the DEMO[2, 3]. Analysis on deformation and fracture also
provided post-irradiation constitutive equations. This and the fracture
behavior are essential for developing a design methodology.
Effects of irradiation on tensile, fracture and creep properties are
summarized, as well as the analysis of deformation. Methods toimprove post irradiation fracture resistance are also introduced.
1) Tensile property: Below 400oC, irradiation often causes hardening
and reduction of elongation (see, Fig. 1). The reduction of elongation
has been recognized as an issue, however detailed analysis revealed
that relatively large ductility remained even after irradiation [4].
Moreover, tightening/optimization of the heat treatment condition
was found to keep post irradiation ductility even higher [3].

the mechanism of cracking to promote failure at crystallographic
boundaries, although it introduced no apparent change in DBTT-shift[4, 5]. On the other hand, reduction of the post irradiation DBTT has
been successfully achieved by tightening/optimization of heat
treatment condition before irradiation (see, Fig. 3) [5].

3) Irradiation creep: Irradiation creep strain has been evaluated fromdiametral change of pressurized tube specimens. At 300 and 500oC,
creep strains were rather small and almost proportional to hoop stressbelow 380 and 180 MPa, respectively [6].
4) Modeling of deformation and fracture (Macroscopic models):
Analysis of the deformation of tensile specimens with macroscopic
defects (e.g. holes) has been conducted to evaluate constitutive
equation after irradiation [7]. The strain distribution was measured
with 3D image analysis equipment and optical microscopy. Either
Ludwik or Swift type constitutive equations was applied, andstress-strain relations have been successfully reproduced to fracturestrain levels. This provides the fundamentals required for a design
methodology for components under intense neutron irradiation [2].
5) Microstructure and alloy development: Microstructural
examinations including fractography have been conducted. The
results indicate the deteriorating effects of inclusions containing Ti
and N, as well as that by other complex inclusions [8]. Dispersion ofTi and Y containing nano-scale oxide particles in RAF has beensuccessfully achieved by mechanical alloying. One of the alloys,
14YWT exhibited superior strength at high temperatures [9].

2) Fracture toughness: Below 400oC, irradiation also reduces fracture
toughness and upper shelf energy, and increases the shift in ductile tobrittle transition temperature (DBTT). Fig. 2 shows DBTT-shift ofseveral ferritic steels by irradiation. It should be noted that
DBTT-shifts of RAFs are smaller than those of conventional steels.
14 MeV high energy D-T neutrons introduce He atoms at a high rateand is thought to cause additional toughness degradation. Doping of58
Ni and 10B introduces He atoms during irradiation of RAF in HFIR.

Fracture Toughness of HFIR Irradiated Tempered Martensitic Steels

conventional specimens, due to both statistical stressedvolume (SV) and CL size effects. Size adjustment
procedure developed for RPV steel [2] has successfully
been applied to a large database of F82H K Jm measured on
specimens of various size and geometry [3]. The size
adjustment procedure has been applied to a subset of the
JP-26 irradiated specimen data. The CL adjustment isbased on finite element analyses (FEA) of the crack tip
stress field for actual specimen geometry compared to an
ideal small scale yielding condition. The SV effect isadjusted by modified B-1/4 scaling as is incorporated in
ASTM E 1921 Master Curve standard. Details are given in
ref [4]. Figure 2a shows B-adjusted toughness data before(K JB ) and after (K Jr ) the CL adjustment for F82H-IEA

Irradiation up to 11 dpa at temperatures below 400°C
indicated that the magnitude of the shift in ductile-brittle
transition temperature (DBTT) to a higher temperaturedepends on irradiation dose. This is important because
100°C is expected to be the lowest temperature of fusion
reactor blankets [1-3]. Current interest is to determine
whether or not there is a dose at which the change in
DBTT saturates, and to know the degradation level of
toughness at saturation. Additionally, the effect oftransmutation-formed helium on the mechanical properties,
especially fracture toughness, is one of the most important
issues that need to be understood for expected power plant
reactor application. The effects of irradiation up to 20 dpa
on the Charpy impact properties of reduced-activation
ferritic/martensitic steels (RAFs) were investigated.
The irradiation dose dependence of the shift in DBTT('DBTT) for F82H-IEA is summarized in Fig. 1.
Irradiation up to 5 dpa at 300°C shifted the DBTT up tonear room temperature, and there was no obvious
indication suggesting a saturation of the DBTT shift. On
the other hand, the DBTT was not further increased by anincrease in irradiation from 11 dpa [3] to 20 dpa at 380°C.
This result indicates the 'DBTT induced by irradiation
around 380°C was saturated at 11 dpa.
The effects of prior austenite grain size on DBTT shift
were investigated by comparing F82H-IEA (ASTM grain
size 3.3) to F82H-HT2 (ASTM grain size 6.5). The finegrain structure in F82H-HT2 was obtained byrenormalizing F82H-IEA using a lower austenitization
temperature (920°C). The results show that the DBTT ofboth unirradiated and irradiated HT2 are slightly (~20°C)
lower than for F82H-IEA, and the finer-grain F82H-HT2
has a higher USE than F82H-IEA. (see Fig. 2). From theseresults, it is concluded that F82H-HT2 benefited from thefine grain size after irradiation compared to F82H-IEA
steel.
The correlation between 'DBTT and yield stressincrease ('V y ) is shown in Fig. 3 for F82H-IEA, F82HHT2, F82H+2Ni, 9Cr-2WVTa and JLF-1. The three F82H
variants follow the same trend. Ni-doped specimens arealso on the same trend. From these data, the large 'DBTTof Ni-doped F82H could be explained as the effect ofradiation hardening, just as the other steels. The values for
9Cr-2WVTa and JLF-1 are slightly lower than the main
trend. The reason for this difference between F82H and thetwo 9Cr steels was not clarified in this study, and will be
investigated further in the future.

performance of DBTT would be maintained at higher
damage levels.
Results of irradiation experiments on mechanicalproperties at temperatures from 250 to 500oC at damagelevels up to 20 dpa indicated that the irradiation effects
were in a manageable range. Improvements of postirradiation toughness and ductility by optimization andtightening of tempering condition are quite beneficial toexpand the service condition of RAF/M and seem todeliver more flexibility for DEMO design. The
methodology of improving post-irradiation toughness
and ductility is also expected to be applicable for other
RAF/M steels.

The reduced activation ferritic/martensitic (RAF/M)
steel F82H is recognized to be a leading candidate
material for in-vessel components in a future fusion
DEMO reactor, as well as that for ITER test blanket
modules (TBM) in Japan [1]. Examination of theneutron irradiation response of RAF/M steels has been
carried out mainly in DOE-JAEA collaborative
experiments using the High Flux Isotope Reactor at Oak
Ridge National Laboratory. F82H is the reference heat
for the collaborative experiments. The results ofrecently completed post-irradiation examination
demonstrated a remarkable improvement in theirradiation-induced degradation of fracture toughness
after optimizing and tightening the heat treatment
condition. The degradation of fracture toughness wasevaluated by the shift of ductile to brittle transition
temperature (DBTT-shift). The optimization andtightening of tempering condition are also revealed tobe effective for maintaining post-irradiation ductility.
DBTT-shift and reduction of ductility by irradiation
have been recognized to be critical issues for RAF/M
steels; therefore, the beneficial effect of the
optimization of tempering condition may be to extend
the service conditions of RAF/M steels.
After irradiation, the DBTT is known to be
dominated by hardness or flow stress level. Some of thetensile results of irradiated weld joint specimens
indicated that the post-irradiation flow stress level
might be reduced by modification of tempering
conditions [2]. Based on this knowledge, ion andneutron irradiation experiments have been carried out toexamine the dependence of post-irradiation hardness
and ductility on tempering conditions using hardness
and tensile specimens, respectively [3]. The specimens
were tempered between 700 and 800oC for 0.5 to 10 hrs
before irradiation. Results showed that longer tempering
times are beneficial for reducing the post-irradiation
hardness. Miniaturized bend bar specimens (half size of
1/3-CVN specimen) with fatigue pre-crack weretempered at higher temperature and/or for longer time.
The specimens were irradiated to 20 dpa and tested atseveral temperatures. Figure 1 shows the results. Data
points for IEA-F82H show the result at a reference
tempering condition of 750 oC for 1h. Data for a longer
tempering time (700oC for 10 hrs), noted as a “Mod1Series” clearly exhibit lower DBTT after irradiation.
The DBTTs are about 0 and 50oC for Mod1 and IEA,
respectively. The DBTT reduced by about 50oC.
Although the 20 dpa damage level is much less than thetarget of 100 dpa for DEMO, the tendency for the
DBTT-shift to saturate with increasing damage level
suggests that the large improvement of irradiation

Vickers hardness Hv(500gf)

To validate the potential of reduced-activation
ferritic/martensitic steel (RAFM) as a structural material
for fusion power plants, the methodology for joining thesteel to form welds with adequate toughness before andafter irradiation must be developed. An irradiated tungsten
inert-gas (TIG) weld (weld metal, base metal and heataffected zone (HAZ)) of the IEA-modified F82H (F82HIEA) was investigated. Post-irradiation tensile tests and ahardness trace across the irradiated weld joint was
conducted to investigate the mechanical property changesof the TIG weld and to identify the location of the weldthat was involved with this low hardening.
Post-irradiation tensile tests of F82H-IEA TIG
weldment specimens were conducted. The results
indicated that the weld metal exhibited nearly the same
irradiation hardening as the base metal, but the HAZ
showed far less hardening than the base metal (Fig. 1).
The microstructure of the TIG weldment is shown in
Fig. 2. The microstructure consisted of 3 regions; i.e., weld
metal, HAZ, and base metal. The HAZ can be further
divided into 3 regions with obviously different
microstructures, and those regions are denoted with circled
numbers in Fig. 2. Here we call the boundary line between
region 1 and region 2 the transformation line, sincetheDJ transformation occurred during welding within theregion inside these lines. It should be noted that the
microstructure of the weld metal was rather fine except for
the last pass region, and the HAZ was wider than that of asingle-pass weldment, since a multi-pass TIG weld wasused.
The microhardness profiles across the weld joint are
shown in Fig. 3. Figure 3 (a) shows that minimum
hardness was obtained for both unirradiated and irradiatedspecimens in the “over-tempered region,” the region next
to the transformation line in region 1. On the other hand,both the minimum 'Hv and the minimum hardening ratio
were obtained in the “over-tempered region” (region 1)
and “fine-grain region” (region 2) located next to thetransformation line in region 2.
The tensile results suggest that a TIG weld joint of
F82H exhibited low irradiation hardening in a tensile test,compared to the base metal, and microhardness tests andmicrostructure observation revealed that the over-temperedzone in the HAZ exhibited similar good performance, i.e.,
low irradiation hardening. Hashimoto et.al. performed
transmission electron microscopy to analyze themicrostructure of these regions in the irradiated weldments[2]. No visible dislocation loops were observed in theover-tempered region and the fine-grained region. Small
dislocation loops were the main microstructural features in

F82H irradiated up to 5 dpa at 573K. This result indicatesthat more active point defect absorption and recombination took place in those regions, and they show
smaller irradiation hardening as a result.

Irradiation effects on precipitation in reduced activation ferritic steels
the decrease of the M 23 C 6 peaks of F82H-2Ni after
irradiation. It also should be noted that the spectra of allirradiated specimens tended to have broad and shallow
peaks with the median about 42 degrees.
These analyses suggest that irradiation caused (1)an increase of the amount of precipitates (mainly
M 23 C 6 ), (2) an increase of Cr and decrease of W
contained in precipitates, and (3) the disappearance ofMX (TaC) in ORNL9Cr and JLF-1.

JAEA, *ORNLReduced-activation
ferritic/martensitic
steels(RAFs), such as F82H-IEA and its variants, ORNL9Cr2WVTa, JLF-1 and 2%Ni-doped F82H, show a varietyof changes in ductile-brittle transition temperature(DBTT) and yield stress after irradiation at 573K up to
5 dpa [1]. These differences could not be interpreted as
an effect of irradiation hardening caused by dislocation
loop formation.
The effects of irradiation on precipitation of RAFs
were investigated to determine how these effects might
affect the mechanical properties. The precipitation
behavior of the irradiated steels was examined byweight analysis, X-ray diffraction analysis and chemical
analysis on extraction residue.
The mass of extracted residue before and after
irradiation is shown in Fig. 1. Here the mass of residue
obtained with the coarse filter (column denoted ‘Large’)is interpreted as the value corresponding to the mass oflarge precipitates, and the difference of mass obtainedwith the fine filter and the coarse filter (column denoted‘Small’) is interpreted as that of the small precipitates.
These results indicate that during irradiation (1) the
mass of larger precipitates increased in F82H-IEA, JLF1, ORNL9Cr and F82H+2Ni, (2) small mass change
occurred in F82H HT2, (3) small precipitates
disappeared in JLF-1, and (4) the amount of small
precipitates doubled in F82H+2Ni.
The chemical composition of extracted residue wasanalyzed and the results show that (1) the precipitatesconsisted mainly of Cr, Fe, V and W, (2) Cr increased
after irradiation of each RAF except for JLF-1, and (3)W decreased after irradiation. It should be noted that (1)about half of the Ta was included in precipitates before
irradiation but dissolved after irradiation in JLF-1 and
ORNL9Cr, and (2) the amount of Ni in precipitatesfrom F82H+2Ni doubled after irradiation.
The XRD analysis of extracted residue (Fig. 2)
revealed that the majority of precipitates are M 23 C 6
type (denoted with diamond mark) for all unirradiatedand irradiated steels. Three distinctive peaks (denotedwith triangle) are observed on unirradiated JLF-1 and
ORNL9Cr, and those peaks are not detected onirradiated specimens. There is no exact match pattern
for those peaks, but the best match is for the TaC. This
supposition is quite reasonable as a high number densityof Ta- and V-rich precipitates is observed in thesesteels[2], and this agrees with the change of V and Ta
mass in precipitates. The reason for these peak offsetsfrom TaC could be that MX is a combination of V- andTa-rich carbides, nitrides, and carbonitrides (M: Ta, V,
Ti; X: C, N). The other feature obtained from Fig. 2 isFig. 1. Mass of residue of unirradiated and irradiatedRAFs extracted with coarse filter (Large) and fine filter(Large + Small).

Creep behavior of RAFM irradiated at 300 and 500oC up to 5 dpa
A small piece was cut from the center of each
irradiated tube after diametral measurement. The
microstructural examination with FIBed samples andreplica films was carried out using TEM. At 300oC
irradiation, a microstructure in hoop stress level
250MPa was similar to a microstructure with
not-pressurized tube. Precipitates also were observed
along Lath and prior J-boundaries. As results ofextraction replica sample, finer spherical precipitations
were observed in highest hoop stress level. At 500oC
irradiation, large precipitations (>200nm) wereobserved along the grain boundary in hoop stress level
200MPa.
These results provide the irradiation creep data fora materials database for blanket structural design infusion reactors.

Reduced activation ferritic/martensitic steels(RAFM) are the most promising candidates for blanket
structural materials for fusion reactors. Irradiation
creep has been recognized as one of the most important
properties for engineering data due to the blanket
structural design. Several researchers have reported
on irradiation creep and void swelling behavior ofaustenitic stainless steels (Type 316 and PCA) andferritic steels (HT9 and 9Cr-1Mo) irradiated above
400oC[1-6]. In addition, some results of irradiation
creep experiments on RAFM above 390oC have beenreported by the Japan/US collaboration program forfusion materials [7].
For fusion reactors, it isanticipated that irradiation creep of RAFM at lower
temperatures could be also significant, and this would
have a large impact on the life expectancy of awater-cooled blanket system. However, irradiation
creep behavior of RAFM at temperatures below 400oC
has not yet been reported.
In HFIR Phase IV program, creep tube specimens
irradiated up to 5dpa at 300 and 500oC were measured
in ORNL Hot Laboratory.
The materials were the RAFM steels (F82H
prepared by JAERI and JLF-1 prepared by MEXT). The
tube specimens had dimensions of 4.57mm outside
diameter and 22.4mm length with a 0.2mm wall
thickness as shown in Fig. 1. End caps were electron
beam welded to the tube segments, and the specimens
were pressurized with high purity helium (99.999% He)
to obtain the desired hoop stresses at the irradiation
temperatures. The hoop stresses ranged from 0 to
400MPa at the irradiation temperature. The diameter ofthese tubes was measured in PNNL before irradiation.
Irradiation was performed in HFIR up to 5dpa. The
tubes were measured with a non-contacting laser
micrometer system.
Fig. 2 shows the relationship between the total
diamentral strain and the hoop stress in RAFM
irradiated at 300 and 500oC. RAFM steels exhibit
similar irradiation creep behavior at 300oC up to 5dpa.
The irradiation creep in these steels irradiated at 300oC
is almost linearly dependent on the hoop stress level
less than 380MPa. Above 380MPa, creep strain tends toincrease strongly with increasing stress. For 500oC
irradiation, the irradiation creep of F82H is linearly
dependent on the hoop stress level below 180MPa. At
higher stress levels, the creep strain increased strongly
in these steels because thermal creep had also occurred
during irradiation.

Plastic property and fracture condition of structural steels after irradiation
Category: Fusion engineering/HFIRYear-Number㸸04-09 - No. 8
K.Suzuki, T.Taguchi, N.Okubo and S.Jitsukawa, JAEA
At temperatures lower than 700K, irradiation often cause a severe
hardening to introduce a large change in stress-strain relation [1]. The
present authors, however, have indicated that the plastic property
before and after irradiation may be expressed by a simple equation of
V = A(H0 + Hp)n (1) where H0, Hp, A and n are an equivalent plasticstrain by irradiation hardening, plastic strain, strength coefficient andwork hardening exponent, respectively; A and n are the constants
without regard to the hardening level by irradiation. Similar
discussion has been also made in several researches [2-6]. The
present authors also indicated the relatively large margin to ductile
fracture was remained even after irradiation to some tens of dpas. In
case the equation (1) is applicable for the plastic property of irradiatedalloys, ductile fracture condition under tensile forces may be
estimated by e.g. Hill’s or Ghosh’s criteria [7, 8]. In other words,
irradiation hardened steel which has been recognized as a quasi-brittle
material is still ductile enough depending on the deformation mode.
In the present paper, plastic properties of irradiated steels are
introduced. Features of structural design criteria for intensely
irradiated steel component are also introduced.
A reduced activation ferritic steel F82H (0.1C-7.8Cr-2W-0.04Ta-Febal.) in normalized and tempered condition was used. Tensile
specimens of the steels were irradiated to 5 to 30 dpa at temperatures
between 250 to 400C in HFIR (some of the specimens were
irradiated in JMTR). Size of the gage region is 7.6mm long-1.5mm
wide-0.76mm-thickness. Specimens were also obtained from cold
worked plates. All the mechanical tests on irradiated specimens were
performed at room temperature in JMTR hot cell. The images ofgage region during deformation were recorded continuously.
Irradiation hardening caused to reduce tensile elongation (especially,
uniform elongation often reduced to zero) and to occur plastic
instability, as seen in the engineering stress-strain relation in theliterature [1]. The area at minimum cross section of the specimen
during the tensile test was evaluated from the image of the necked
region. From the area during testing and the engineering stress-strain
relation, an approximate true stress-true strain (Ts-s) curve has beenobtained (strain is in logarithmic strain). Results for the specimens
irradiated to 0, 5 and 20 dpa are shown in Fig. 1 (a). The curves for 5
and 20 dpa irradiated specimens were shifted along strain axis tooverlap the Ts-s curve for the unirrdiated specimen (see also Fig.
2(b)). The figure clearly shows that the curves overlap well with eachother, indicating that the equation (1) is applicable for the Ts-s relation
before and after irradiation without regard to irradiation damagelevels. The values of e0 applied for the curves of the specimens
irradiated to 5 and 20 dpa were of 0.33 and 0.7, respectively. Even
after irradiation to 20 dpa, residual ductility was about 30% of that
before irradiation. Indeed, as seen in Fig.2, effect of structural
discontinuity (circular hole at the center of the strip) was observed tobe relaxed during deformation before cracking had occurred [2];general yield occurred before the load attained maximum suggesting
considerable level of margin remained even for the specimen withdiscontinuity after irradiation and this was followed by neckdevelopment (images of the deformed specimens were also reported[2]). Moreover, bend testing on simulated irradiation hardened
specimen by cold working exhibited no apparent plastic instability.
As indicated above, the margin to fracture can be determined as afunction of deformation mode either by calculation or experiment.
This is also true for austenitics [4]. Structural design criteria assuring
the structural integrity of intensely irradiated steel component
delivering more freedom to designing comparing with current
methodology has began to be developed based on the analysis ofplastic and ductile fracture condition behavior after irradiation[2].

fibers, presenting river-like patterns originating fromindefinite mirrors around the fracture origins either on thesurface or at the fiber interior. No significant different in
the fracture surfaces, irradiated and unirradiated, wasobserved.
The swelling and the through-thickness thermal
conductivity, shown in Table 1, indicated the absence ofprogressive property evolution beyond a few dpa, proving
true saturation in key properties[2]. The electricalresistivity measurement revealed a transition from theunirradiated nearly temperature-independent conduction of
pyrocarbon interphase into a reduced, moderately
temperature-dependent conduction[1]. The effect ofirradiation on the composite electrical resistivity appeared
to be relatively minor. Overall, outstanding irradiation
resistance of the nuclear grade SiC/SiC composite toneutron irradiation to a dose exceeding 40 dpa attemperature of 800ºC was demonstrated.

Silicon carbide (SiC) has been studied for fission fuelapplications for several decades, and for the past two
decades as the base material for SiC fiber-reinforced SiCmatrix (SiC/SiC) composites, a potential high-temperature,
low-activation structural material for fusion energy. The
primary focus of study has been the development of aradiation stable material, given the poor as-irradiatedperformance of early materials. Over the past decadesignificant progress has been made towards this goal withthe development of what is now considered a nuclear grade
SiC/SiC composite composed of high purity, nearstoichiometric, and dense fibers and matrix. However,these composite materials have not been demonstrated toretain such fundamental properties as strength anddimensional stability under the high-dose irradiation typicalof power reactor blankets. In the DOE/JAEA fusionmaterials collaboration, the high-dose stability of thecurrent nuclear grade SiC/SiC composite was examined.
The material examined was chemically vaporinfiltrated (CVI) SiC matrix, Hi-Nicalon™ Type-S (HNLS)
SiC
fiber-reinforced
compositewithmultilayer
pyrocarbon/SiC interphase. Rectangular flexure beams
measuring 50.2 x 6.35 x 2.63 (mm) were irradiated in HFIR
to ~41 dpa at 800ºC. Post-irradiation mechanical properties
are briefly discussed in the present report, whereas the moredetailed report is found elsewhere.[1]The results of the post-irradiation examination aresummarized in Table 1. The composite material retained its
unirradiated ultimate and the proportional limit stresses
after irradiation. Moreover, no significant increase in data
scatter was observed for either property. Slight increases inboth the ultimate and proportional limit stresses may havebeen the case, but this increase is not statistically significant.
Examples of the recorded load – crosshead displacement
curves are presented in Fig. 1, showing no noticeable
difference between the unirradiated and irradiatedconditions. From these observations and accepted
composite theory it can be reasonably concluded that no
significant effect of irradiation on either the fracture energyof the matrix material, CVI SiC or the statistical strength
properties of the reinforcing fibers.
The fracture surfaces of the broken samples were
examined, and high magnification images of both thecomposite fracture surfaces and the fiber fracture surfaces
were compared for regions under tensile stress during
testing. The composite fracture surfaces were characterized
by generally very short yet finite fiber pull-out length anddebond/slide at the interface of the fiber and the interphase
whether or not the material has been irradiated. Both theunirradiated and irradiated fiber surfaces appear to be
typical of those observed for intact Hi-Nicalon™ Type-S

Modeling the Influence of Helium on Iron-based Alloys

In the investigation of helium bubbles, it was foundthat the helium atoms stand off a small distance from thesurface iron atoms, leaving a between the He and Fe matrix
atoms on the surface of the bubble [2]. The gap was large
enough that the He atoms rarely come close enough to aniron atom to invoke the 3-body component of the ORNL
Fe–He potential (range 2.2Å), so their interactions are
effectively described by the pair part of the potential. The
helium density oscillates enough to suggest a shell structure
to the arrangement of atoms, but not enough to suggest
solid helium. This agrees with predictions that the heliumin the bubble would not be solid. In a void, the surface
matrix atoms relax inwards slightly, reducing the volumeof the void. At higher temperatures, they move in more dueto the thermal expansion of the iron. Adding helium to thevoid pushes the atoms outwards, increasing the volume
again. The more helium added, the further the bubble
expands. There is a point where the forces balance and the
bubble is neither expanded nor contracted; the surface
atoms are at the same place as they would be in a perfectlattice. We use this point as our condition for equilibrium.
The equilibrium He/V ratio is temperature and size
dependant. In general, the equilibrium He/V ratio is lower
for higher temperatures and larger bubbles.
Figure 1 shows the dilation of a 2 nm diameter bubble
as a function of He/V ratio for different temperatures. The
equilibrium ratio for each temperature can be determinedby where it crosses the horizontal zero line. At 2 nm, thecurves for the different temperatures are close together andthe equilibrium He/V ratios lie in the range 0.4–0.55; forlarger bubbles, the curves spread out more (not shown).

In fusion applications, helium created bytransmutation plays an important role in the response of
reduced-activation ferritic/martensitic (RAFM) steels toneutron radiation damage. We have performed extensive
atomistic simulations using the ORNL 3-body Fe–He
interatomic potential [1] combined with three interatomic
potentials for the iron matrix. Interstitial helium is very
mobile and coalesces together to form clusters; the growthand mobility of these clusters has been investigated. Whenan interstitial He cluster reaches sufficient size, it punches
out an Fe interstitial, creating an immobile helium–vacancy
cluster. If more helium atoms join it, more Fe interstitials
can be created; the He–V defect is a nascent bubble. Thesemechanisms have been investigated together in simulations
that examine the nucleation of He defects. Mobileinterstitial He clusters and helium bubbles from 1 to 6 nm
in diameter were also simulated separately.
Helium-vacancy cluster growth and coalescence werestudied in molecular dynamics simulations to investigate
the nucleation of helium bubbles from interstitial helium
atoms using the Ackland iron and ORNL He–Fe potentials.
He interstitial cluster growth, coalescence and Frenkel paircreation were almost negligible at 200K but prevalent at all
higher temperatures. The temperature affected not just therate but also the nature of the defect creation process. The
higher the temperature, the faster He atoms and clusters
diffuse, which makes coalescence occur faster. This isbalanced by higher temperatures leading to small clusters
being broken up, delaying the creation of larger, stableclusters. The result is that that the cluster size distribution
is temperature dependant; higher temperatures lead to
fewer but larger clusters. Higher temperatures also increase
the number of Frenkel pairs likely to be emitted from alarger He–V cluster.
Diffusion rates for clusters of 1 to 6 interstitial helium
atoms were calculated for several combinations ofpotentials. Various combination of Fe and HE-Fe potentials
were compared. In general, larger clusters were found todiffuse slower, however there were significant differences
between the potentials. He-2 clusters tended to have asimilar or lower energy barrier than single interstitialhelium atoms but still diffuse slower due to a lower preexponential factor. The ORNL and Wilson potentials show
significantly higher barriers for He-3 and larger. The J–N
potential shows barriers of about 0.06eV for clusters of 1 to
4 interstitials, with the pre-exponential factor decreasing
with increasing cluster size. He-5 was found to have a(usually substantially) lower migration barrier than He-4
with all combinations of potentials used. A possible
explanation is that the tetrahedral arrangement of He-4 ismuch more stable due to its high symmetry that matches
the symmetry of the Fe matrix. He-5 configurations are farless symmetrical and, in some potentials, allow for rapid
1D diffusion.
