Subject:
Proposed Amendment #6 of the Be.keley Research Reactor Facility Operating License
Dear Mr. Adams:
The University of California, Derl<eley terminated operation of its TRIGA III Reactor on January 1,1988.
This letter is intended to request a revision in the Berkeley Research I
Reactor, Technical Specifications as follows:
1.
Delete item 1.2.c on page 1 of the Berkeley Research Reactor's Technical Specifications.
l 2.
Add item 1.34 on page 5 of the Berkeley Research Reactor's Technical Specifications, as follows:
Fuel llandling 1.34 Fuel llandling i
l For the purpose of defueling the reactor, Fuel llandling is defined as in core loading or unloading of fuel elements including instrumented fuel elements, fuel followers and control rods.
During Fuel llandling, the following conditions shall be followed:
(0 ggrq88:e rd8He i
i
.\\
2 a.
A licensed operator or senior operator at the console to monitot-the neutron population in the core environment through the Reactor start up channel.
b.
The following nmnitors shall be operable:
Bridge area monitor and 2 other area monitors Stackgas monitor Air Paeticulate monitor A portable survey meter Neutrc,n, beta and gamma film hadges shall be worn by all l
c.
personnel directly involved l
d.
Normal ventilation shall be maintained Prior to Fuel llandlina, the reactor shutdown margin shall be calculated.
The proposed revision has been reviewed and approved by the Reactor llazards Committee and the reactor staff. The revision is necessary, because we i
believe that the current specifications no longer serves its purpcsc.
A safety evaluation to justi'y the request for the revision is attached.
If you have further questions. please call me at 41f 642 7071 or Dr. T(k II. Lim at 415 642 5213.
Sincerely yours,

Safety Evaluation Oct 10,1988 The request for changes of Item 1.2.c on page 1 and the addition of Item 1.34 on page 5 of the Berkeley Research Reactor Technical Specifications were reviewed by the Reactor Hazard Committee and the Reactor Staff. He following safety practices and past experience were the bases for the safety evaluation:
a.
Fuel handling has been performed safely since 1960.
b.
A Licenced Operator or Senior Operator shall monitor the neutron population in the core environment during fuel handling operation. Past experience indicated that the reactor start-up channel (a fission detector) can effectively serve this purpose. The stan-up channel is connected in such a way that it funtions all the time regardless of the console "power on" switch; testing of the entire function of the console prior to fuel handling is thus meaningless.
c.
Unloading of fuel shall follow a patem of increasing shutdown margin.
These changes do not constitute an unreviewed safety question in that:
1.
It does not increase the probability of occurance of an accident analyzed in the Safety Analysis Report 2.
It does not increase the consequences of an accident analyzed in the Safety Analysis Report 3.
It does not create the possibility of occurrence of nuclear accident not previously analyzed in the Safety Analysis Report.
