Tennessee Valley Authority, Post Office Box 2000. Decatur, Alabama 35609 TVA-BFN-TS-305 10 CFR 50.90 U.S. Nuclear Regulatory Commission ATTN:
Document Control Desk Washington, D.C.
20555 Gentlemen:
In the Matter of Tennessee Valley Authority Docket No. 50-260 BROWNS FERRY NUCLEAR PLANT (BFN) TVA BFN REQUEST FOR TECHNICAL SPECIFICATION (TS) NO.
305 FOR UNIT 2 LIMITING CONDITION FOR OPERATION (LCO) REQUIREMENTS 3.7.G.l.a AND 3.7.G.3 In accordance with the provisions of 10 CFR 50.4 and 50.90, we are submitting a request for an amendment to license DPR-52 to change the BFN Technical Specifications for Unit 2 (Enclosure 1).
The proposed amendment will revise the LCO requirement for requiring two operable Containment Atmosphere Dilution (CAD) systems during plant operation.
On October 16,
- 1991, BFN staff discovered that CAD tank B was venting nitrogen at an unusually high rate and the vacuum in the insulation space surrounding the tank had degraded.
Efforts to locate and repair the leak confirmed that the leak was not due to atmosphere entering the vacuum space from outside the tank; therefore, the leak is believed to be the internal liquid nitrogen storage tank leaking nitrogen gas into the space.
Location and repair of such a leak requires cutting into the outer shell of the tank and possibly extensive disassembly.
This repair will likely require more time than the 30 days allowed by technical specifications and a forced plant shutdown would be required without a TS change.
