SUBJECT:
REVIEW 0F LICENSE AMENDMENT APPLICATION DATED MAY 16, 1986, AND SUPPLEMENT DATED MAY 23, 1986 BACKGROUND Texas Utilities Generating Company, on behalf of Texas Utilities Electric Company, Texas Municipal Power Agency, Brazos Electric Power Cooperative,Inc.,
and Tex-La Electric Cooperative of Texas, Inc., by application dated May 16, 1986, and its supplement dated May 23, 1986, requested Special Nuclear Material License No. SNM-1912 be amended authorizing the receipt, possession, inspection, storage, use, and packaging for delivery to a carrier a maximum of 40 grams total of U-235 in uranium enriched to a maximum of 93.5 percent in the U-235 isotope. The material is in the form of uranium oxide in sealed ex. ao neutron detector assemblies. The present SNM license only authorizes the receipt, possession, inspection, storage, and packaging of fuel assemblies containing 2,200 kilograms of U-235 in uranium enriched to no more than 3.20 percent in U-235.
DISCUSSION
- 1. Radiation Safety Radiation Protection is responsible for both the monitoring and performing of periodic inventories of the licensed material. The Radiation Protection Engineer is responsible for implementation of the health physics program.
Since the excore detectors are sealed sources, there should be no health physics problem associated with their storage and use at the CPSES.
- 2. Nuclear Criticality Safety and Physical Protection The 40 grams contained U-235 is approximately 5 percent of the minimum critical mass under optimun conditions of fuel piece, size, water moderation, and reflection. Therefore, there is no potential for criticality with the excore detectors. Interaction between the detectors and the fuel assemblies present in the facility is also negligible.

l MAY 2 91986 While temporarily stored in the warehouse, the detectors are in a locked, secured area. Access to the area is controlled. The excore neutron detectors will be transferred to the Reactor Building and installed in the wells ad,Jacent to the reactor core in accordance with both health physics and radiation protection procedures. All radioactive materials, prior to transfer between radiation controlled areas (e.g., Fuel Building to Reactor Building), are monitored and authorized for transfer by Radiation Protection. Therefore, both the health and safety of the personnel and physical protection of the SNM is assured.
- 3. Environmental Effects There is no change in the environmental protection requirements of the facility.
None are required since the requested authorization is a change in process that does not affect the environment. In accordance with 10 CFR 51.22(c)(ll),
neither an Environmental Assessment nor an Environmental Impact Statement is warranted for this propos t.@.td a.ch.:.v.t . ..yLThlt.me,,, . .yIC rp.v. . . . . .. .. . . . ... .
