Report on the 13th Meeting of the Joint Working Group of
the U.S-Japan Coordinating Committee of Fusion Energy
on Safety in Inter-Institutional Collaborations(U.S.-Japan Safety Monitoring Program)February 22-25, 2010

PURPOSEThe purpose of the 13th meeting of the U.S.-Japan Safety Monitor Joint Working Group was
to informally evaluate the programmatic aspects of environmental, health and safety (ESH)
programs in U.S. fusion research facilities by touring laboratory areas and meeting withresearchers and safety professionals. Based in these interactions, the U.S.-Japan delegation
was able to share information and provide suggestions in an effort to reduce the likelihood of
bodily injury and/or property damage.

In addition, good approaches and practices developed

at different institutions should be utilized to improve environmental, health and safety
programs at other institutions.

EXECUTIVE SUMMARY
The Japanese delegation to the 13th meeting of the U.S.-Japan Safety Monitor Joint Working
Group consisted of the following individuals:
Kiyohiko Nishimura

Director, Safety & Environmental Research Center NIFS

Yuichi Takase

Professor, Graduate School of Frontier Sciences

Univ. of Tokyo

Atsuhiko M. Sukegawa Manager, JT-60 Safety Assessment Group

JAEA

Tetsuo Seki

NIFS

Associate Professor, LHD project

The main U.S. Participants were:
Keith Rule, Senior Program Engineer, Princeton Plasma Physics Lab
Richard Savercool, Safety Engineer, General Atomics
Three members (Professor Nishimura of NIFS, Associate Professor Seki of NIFS, and Dr.
Sukegawa of JAEA) of the Japanese delegation participated for the first time in the Japan-US
Safety Monitoring Joint Working Group.

The Japanese delegation was greatly impressed byhigh attention to the ES&H and established safety organization. At most institutions, ES&H
policies are based on the concept of Integrated Safety Management (ISM). DOE provides
the basic guidelines of ISM, but its implementation is performed by discretion of each1

institution. Each institution has a comprehensive training program which has been useful indeepening the awareness of hazards and reducing the number of accidents/incidents.

At

many institutions ES&H related information is readily available electronically, and it ispossible to make an application for training program online.

In some institutions, a personal

attendance history of a necessary training program is managed online, and suitable measures
such as prohibition of entrance are taken automatically for a person who does not takenecessary lectures.
satisfactory.

The overall evaluation of the 2009 site visits by the JWG is highly

In particular, understanding of differences in safety culture between the twocountries and between the different states in USA is worthy of note.

At institutes with many

visiting scientists or workers from the outside, it is extremely important for everyone to haveknowledge of safety.

Therefore, Japanese visitors were able to recognize the importance ofsafety education based on a difference in safety standards in various countries.

Issues called to the attention to the lab staff :The accumulated dose limits for workers in GA and for site boundary have been eased in
January 2010.

There was no information the dose limit for living space (non restricted area)2

in GA.

The DIII-D has been operated within theallowed limit neutron emissions until now. (A.S.)
Totally, radiation seems to be well controlled.
The JT-60 had the interlock system related to theamount of the neutron emission.

Although DIII-D

doesn't have such interlock system, total amount of
the neutron is controlled by the operation of the NB
injector (input). (A.S.)
Near the Li-Pellets diagnostics system in the
restricted area, a worker is working without a mask.
Please consider wearing a mask during work in the
restricted area to prevent internal exposure by theradioactive dusts (Fig. 1). (A.S.)

Fig. 1. Worker near the Li-Pellets
diagnostics.

Monitoring system by the warning light (thedifference of the color) is good (Fig. 2). (A.S., K.N.)
Wiring in the Gyrotron room is good.

We could

not find wiring without support.

Most of cables were

wired in the space under the floor.

It is very good

The entrance of the room in which the high voltage is used is restricted severely and theinformation for this room condition is displayed in front of the room (Fig. 4). (T.S.)
Entering the experimental hall is controlled by the key control system (KIRK Key) (Fig. 5).
(T.S.)

The security of the computer system is still
under consideration, due to considerations forease of use and the safety control.

They have

paid special attention to the arc-flash during
the handling of the high voltage, for example,
wearing proper eye protection.

Totally, we

felt the careful attention to the safety. (T.S.)
The capacitors were placed near the wall.
Some terminals were grounded, and the others
were not grounded.

To prevent an electric

shock, capacitor terminal should be terminatedwhen not in use (Fig. 6). (K.N.)
The indication of “EXIT” on the floor is agood idea. If it was made by the fluorescentmaterial, it can be seen during a power failure(Fig. 7). (K.N.)

Issues called to the attention to the lab staff :“Roles and Responsibilities for EHS”, “Design of the EHS system for Alcator C-Mod andthe PSFC” and “PSFC ES&H program” are helpful for us to improve the ES&H system inJapan. (A.S)
Since there are many earthquakes in Japan,
Japanese regulation does not allow stacking
heavy things on a tall shelf without measures toprevent a falling accident.

In MIT, theirregulation does not forbid to stack heavyequipment on a tall shelf.

Such difference isbase on a safety standard between Japan and theeast coast in Unite States. (A.S., K.N.)

were in the passage way and could prevent
safety walking.

They should be kept atprescribed places (Fig. 8). (T.S.)
The electric saw has some emergency stop
equipment such as “SAW STOP” (Fig. 9).
This is good for the worker’s safety. (T.S.)

The current terminals of high voltage or high current
should be coved with protecting cover to prevent an
accident of electric shock (Fig. 10). (K.N.)
A block of lead was put on the floor without any
coatings. Powder of lead and lead oxide give damage
to the health.

To keep lead without coating isforbidden in Japan (Fig. 11). (K.N.)
Local air exhauster was set in the machining area.
This is good for worker’s S&H (Fig. 12). (K.N.)

Issues called to the attention to the lab staff:
MST
Door access is controlled by using the various keys and it is linked to the interlock system(Fig. 18).

It is simple and effective. (A.S., T.S. & K.N.)

Information of hazard by colored warning lightis convenient and effective.

Similar system isapplied in GA and NIFS (Fig. 19). (A.S. & K.N.)

supply board by taping is effective to keep clean
there. If the tape was made by the fluorescentmaterial, it can be seen during a power failure (Fig.
20). (T.S. & K.N.)
Tools, grounded rod, safety equipment andmedical equipment are provided near the entranceof the gate (Fig. 21). (T.S. & K.N.)

Switching of the current terminals is controlled by the keys (Fig. 22). Key system is very
good, but the terminals should be covered completely to prevent the electric shock. (T.S. &K.N.)Fig. 22. Switching of the current terminal is controlled by the key.

Most cylinders in the laboratories are fixed by
one binding (Fig. 23). (T.S. & K.N.)

Such things

have been seen in the laboratories in the East sideof the US.

It is understood as the difference ofsafety standards between Japan and the east coastin Unite States.

Since there are many

earthquakes in Japan, gas cylinder must be fixedby two binders with non flammable wires.
However, the cause of falling down of cylinder is
not only by earthquake. For example, accidental
hard hit of carrying cart may cause falling down.
Especially, one loose binding is dangerous.

Itis better to fix cylinder at two positions.

Fig. 23. Gas cylinders with one
binding.

The protruding of tie wires may wound eyes ofworkers.

They should be cut (Fig. 24). (K.N.)

The edge of stage at the capacitor bank area has
no toe-boards (Fig. 25). (T.S.)

Please consider

installing them to prevent the accidental falls ofequipment.

Fig. 24. The rest parts of bundlingwires.
Fig. 25. Stage at the capacitor bank area.

Pathway in the capacitor bank area is narrow. To prevent an accidental electric shock incase of emergency, the terminals of capacitors should be covered (Fig. 26). (T.S.)
Blocks of lead were put on the stage without any coatings. Powder of lead and lead oxide
may give damage to the health.

To keep lead without coating is forbid in Japan (Fig. 27).
