Letter from EPRI to NRC, "Project No. 704 - BWRVIP-271 NP: BWR Vessel and Internals Project, Testing and Evaluation of the Browns Ferry Unit 2 1200 Capsule," dated April 17, 2013 On April 17, 2013, the Electric Power Research Institute (EPRI), on behalf of the Boiling Water Reactor Vessel and Internals Project (BWRVIP), submitted "BWRVIP-271 NP: BWR Vessel and Internals Project, Testing and Evaluation of the Browns Ferry Unit 2 1200 Capsule" (Reference), as required by Title 10 of the Code of Federal Regulations (10 CFR), Part 50, Appendix H, Section IV B. The Tennessee Valley Authority (TVA) has reviewed the test results provided in BWRVIP-271 NP (Reference) and determined that the Pressure-Temperature (P-T) Limits Curves contained in the Browns Ferry Nuclear Plant (BFN), Unit 2, Technical Specifications (TS) Figures 3.4.9-1 and 3.4.9-2 are non-conservative. Corrective actions are being managed by TVA's corrective action program under Problem Evaluation Report 816957.
BFN is treating the non-conservative P-T Limits Curves as a degraded condition and has established compensatory measures to ensure that the BFN, Unit 2, Reactor Vessel is maintained within acceptable limits. As part of the BFN, Unit 2, License Renewal Application, TVA committed to submit revised BFN, Unit 2, P-T Limits Curves prior to the period of extended operation. As such, WVA will submit a License Amendment Request to revise the BFN, Unit 2, P-T Limits Curves by June 27, 2014.
The approval and implementation of the revised P-T Limits Curves will resolve the degraded condition.

Letter from EPRI to NRC, "Project No. 704 - BWRVIP-271 NP: BWR Vessel and Internals Project, Testing and Evaluation of the Browns Ferry Unit 2 1200 Capsule," dated April 17, 2013 On April 17, 2013, the Electric Power Research Institute (EPRI), on behalf of the Boiling Water Reactor Vessel and Internals Project (BWRVIP), submitted "BWRVIP-271 NP: BWR Vessel and Internals Project, Testing and Evaluation of the Browns Ferry Unit 2 1200 Capsule" (Reference), as required by Title 10 of the Code of Federal Regulations (10 CFR), Part 50, Appendix H,Section IV B. The Tennessee Valley Authority (TVA) has reviewed the test results provided in BWRVIP-271 NP (Reference) and determined that the Pressure-Temperature (P-T) Limits Curves contained in the Browns Ferry Nuclear Plant (BFN), Unit 2, Technical Specifications (TS) Figures 3.4.9-1 and 3.4.9-2 are non-conservative.
