## Divertor Design Tasks

These were not identified in Diagnostic Prot Engineering Task Final
Report Summary

Items included have an element of generality.

They are listed because they must be processed at some stage.

Whether they are appropriate for distributing to an extension of the
port engineering task has still to be discussed within the IT, specially
Divertor Group and Diagn Engineering

Diagnostic Procurement Package 5.5.PN.03 Annex 1.2 Diagnostic Divertor
Closure Plates

2.3 Divertor Diagnostic Rack

Diagnostic components, such as waveguides and optical elements that are
in the divertor port, are mounted on a supporting structure, referred to
as the divertor diagnostic rack. Each is installed in its port, complete
with diagnostic equipment, as one assembly (see Figs 1, 2 and 3 in Annex
2 pt 3). They extend from the back side of the divertor cassette to the
port flange. The diagnostic components (and blocks of water-cooled
shielding) may be at any position on the rack. Specifically in two of
these there are sets of microwave waveguides. The requirements of the
divertor diagnostic rack with microwave waveguides are used as the basis
for this description.

The divertor diagnostic rack is a structure with diagnostic module
locations and is similar for all racks. The diagnostic module locations
are different for each port. Diagnostic modules, waveguides and shield
blocks are attached to the rack at these locations. These elements are
not part of the procurement package.

A rack comprises a welded space-frame assembly of base, side frames,
bracing, carriage, locking and handling features and diagnostic module
locations.

It carries water-cooling pipes from the port flange to the front
portion, and to some of the attached diagnostic or shielding modules,
where there is sufficient nuclear heating to necessitate cooling during
long burn pulses. The cooling channel is in the form of 50mm diameter x
5mm wall stainless steel, seamless, piping welded to the rack components
externally. This part only of the structure is subject to the leak
tightness and leak testing requirements. All of the assembly is subject
to limitations on in-vessel equipment regarding design, material,
off-gassing, cleaning etc.

Diagnostic components (waveguides and optical elements) are mounted in
the rack by simple bolting to reference locations.

The base, frame and bracing of the rack is stiff enough that it offers a
suitable base for the support of optics and can be lifted cantilevered
from the RH features on the outboard end. The base is used as the
support when the rack is finally in the port or when it is in the
maintenance area. When in position, defined by calibrated end stops, the
diagnostic block is locked and the height is set. It is strong enough
that it can support the components in-situ without deflection of more
than 5mm anywhere along its length.

are 2 x 12mm positioning dowel holes and \~9 bolt holes for location and
attachment onto the cassette. The plate is bored with 10mm water cooling
channels. These are sealed with welded plugs, inter-connected and fed by
a standard pair of remotely maintainable water cooling connections.
There are 6 x 100mm through-holes to allow access to the divertor high
heat flux component attachment pins. The instrumentation on the side
plate varies for each plate and will be defined at procurement. Each
sensor position requires a machined location or recess, tapped holes for
attachment, and a groove for the sensor wiring loom. This extends from
the sensor recess to the outboard end of the plate and is typically 10mm
deep (into the plate) x \~20mm wide. Near the outboard end the grooves
from different sensors merge. The routing of the grooves can be adjusted
to best suit other features of the plate.

The diagnostic equipment is provided by ITER to the supplier. Each
sensor has a wiring loom and electrical connector, pre-assembled and
tested. The supplier is required to assemble these to the side plate, by
bolting and locking with small welds.

#### 4.2 Microwave Wave-guide Side Plate Assemblies

The microwave wave-guide side plate assemblies have all of the features
described above for the instrumented side plates. (They also support
diagnostic sensors and instrumentation). In addition there is a series
of grooves, typically 10 per plate, 15mm deep (into the plate) x 20mm
wide. The routing of these grooves is fixed and cannot be adjusted to
suit other features. At the outboard end of the plate is a block \~800
mm long x 280 mm wide x 750 mm high. This is used to support the
wave-guide convertors and connectors. It is also made of stainless steel
and is an integral part of the side plate structure and cooling channel
arrangement. There are 2 x 12mm positioning dowel holes and \~9 x 12mm
counter-bored holes for location and attachment onto the cassette. The
plate is bored with 10mm water cooling channels. These are sealed with
welded plugs, inter-connected and fed by a standard pair of remotely
maintainable water cooling connections. There are 6 x 100mm
through-holes to allow access to the divertor high heat flux component
attachment pins.

The diagnostic wave-guides are provided to the supplier by ITER. Each
wave-guide is pre-assembled and tested. The supplier is required to
install these into the side plate, by bolting and locking with small
welds.

#### 4.3 Central Mirror Mount

The central mirror mount is a stainless steel fabrication 170mm square
cross section x 965 mm long. The plate is bored with 10mm water cooling
channels. These are sealed with welded plugs, inter-connected and fed by
a standard pair of remotely maintainable water cooling connections.

The wall of the mount is typically 15mm thick and has bored cooling
water channels. There are four penetrations for diagnostic viewing
through the wall at various positions. These are typically 10 to 25 mm
wide and up to 200 mm long. Internally there are machined reference
faces and tapped holes for the mounting of up to four metal mirrors. At
the base of the mirror mount is a flange region 250mm square x 50mm deep
that is used to locate the mount in a recess in the bottom of the
divertor cassette. There are 2 x 12mm positioning dowel holes and \~12x
12mm counter-bored holes for location and attachment onto the cassette.

ITER will fit the diagnostic mirrors into the central mirror mounts and
will fit the mirror mount to the diagnostic cassette.

Fig. 9 Diagnostic Interfaces with Cassette, search for Standard
Solutions

1 - Carbon Targets assumed

possible change to metallic target will significantly affect
reflectivity

and possibly diagnostic approach

a -- Viewable Target

b - Highly desirable extension of view required

c - view of typical target required, not edge of casstte or sub-target

2 - Standard Pumping slot has been used for outer and inner target
viewing

aperture may close generally

d - viewing slot should keep full poloidal target view

3 - Dome Liner Gaps have been used for diagnostic viewing

e - central support may be introduced

will be cooled, should be able to support & cool mirror box

4 - Liner side have been used for diagnostic support (instrumented
cassette)

may be removed (with mod e), substitute support is required

\- Narrower liner side has been used as viewing gap

5 - Dome-Liner space sometimes used

avoided in some designs because of uncertainty about dome

used in other designs to get viewing access to b

6 - Under Liner space used - pumping only in one direction

7 - \'Pumping Aperture\' not used for pumping on diagnostic cassettes

used for diagnostic access an cassette centre

f - may close for pumping & shielding reasons - maintain diagnostic
apertures

8 - Target- mid cassette

Thermocouples are required, use pin-hole feature

g - sacrificial (if necessary) in front of water channel and

h - permanent behind

9 - Cassette Body as sprung component

some diagnostic apertures required with

i - replacement stiffness

10 - Lock Actuator split into 2 systems, for some

11 - Anchor and cooling for Electrical Connectors
