SUBJECT:
REQUEST FOR ADDITIONAL INFORMATION RELATED TO TECHNICAL SPECIFICATION REVISION FOR BROWNS FERRY NUCLEAR PLANT, UNIT 2 (TAC NO. MB6811)
Dear Mr. Scalice:
By letter dated October 25, 2002, as supplemented by letter dated December 20, 2002, Tennessee Valley Authority submitted an application to revise the Technical Specifications (TS) for the Browns Ferry Nuclear Plant, Unit 2. The proposed revision includes a change to the safety limit minimum critical power ratio value in TS 2.1.1.2. The U.S. Nuclear Regulatory Commission staff has reviewed your submittals and finds that a response to the enclosed request for additional information is needed before we can complete the review.
This request was discussed with Mr. D. T. Langley and B. Morris of your staff on January 16, 2003, and it was agreed that a response would be provided within 20 days of receipt of this letter.
If you have any questions, please contact me at (301) 415-1496.
Sincerely,
/RA/

- 1. Please provide the rationale for changing the fuel bundles and the core loading pattern shown in Figure 2 of the submittals dated October 25, 2002, and December 20, 2002. Also, provide the reason for increasing the beginning of cycle shutdown margin, and describe the relationship between core loading design/bundle design and increasing the beginning of cycle shutdown margin.
- 2. Please provide your justification that the analysis performed for Unit 2, Cycle 13, single loop operation (SLO) as shown in Table 2 of Enclosure 2, which only provides the results of one case at the beginning of the cycle, is sufficient. Also, describe the impact on the safety limit minimum critical power ratio value for SLO due to end-of-cycle penalty of top-peak power shape.
