NUCLEAR SCIENCE CENTER i January 26,1998 409 845-7551 U.S. Nuclear Regulatory Commission 98-0010 ATTN: Document Control Desk Washington DC 20555 Subiect: Request for Amendment to Technical Specifications of Facility License R-83

Reference:

1. Texas A&M University Nuclear Science Center Reactor License R-83
2. 10 CFR 20.1301(2)
3. Safety Evaluation for the Production oflodine-125 at the Texas A&M University Nuclear Science Center (attached) '

Dear Sir:

The Texas A&M University System Nuclear Science Center has signed a proprietary agreement with a company to produce commercial quantities ofIodine-125. The bulk of the isotope used in the United States is currently produced in Canada. The proprietary content of this application is necessary for a complete regulatory review. The sponsoring company has requested that all information regarding the design be treated as confidential and "Need to Know."

It is requested that the Technical Specifications of R-83 be changed to include the following, inserted as paragraph 3.6.2(c):

Each experiment used for the production ofIodine-125 shall be controlled such that the total inventory of Xenon-125 in an individual experiment is n;s greater  ;

than 1000 Curies. /

The value of 1000 Curies is based on a safety analysis performed at the Nuclear Science Center that calculated exposures to the public to be less than 0.5 rem per year (10 CFR .

20.1301) from an accident. The value of 1000 Curies gives a comfortable margin of /

safety and would result in an Emergency Action Level that requires Alert classification.

The 1000 Curies of Xenon-125 reduces the inventory ofIodine -125 available to approximately 10 Curies per experiment.

The facility Emergency Plan is being updated to include responses to an accidental release of Xenon-125 and the implementing procedures will be approved at a scheduled Reactor Safety Board meeting in mid-February.-
