Dear Mr. Carey:
Subject:
Beaver Valley Unit 1 - Projected Values of Material Properties For Fracture Toughness Requirements For Protection Against Pressurized Thermal Shock Events (TAC 59941)
We have reviewed your letters dated January 21, 1986 and May 16, 1986 which were submitted in response to the Pressurized Thermal Shock (PTS) Rule, 10 CFR 50.61. We have found the material properties of reactor vessel beltline materials, the projected fluence at the inner surface of the reactor vessel for the end of life of the plant and the calculated RT for the end of life of criteria of 270 *F at 32 EFPY which is beyond Nh e$Ib the plant to be acceptable.
The calculated RT below the screening xpiration date of the license and, therefore, meets the requirements of the PTS Rule.
The PTS Rule requires that the projected assessment of the RT must be updatedwheneverchangesincoreloadings,surveillancemeasuNkentsorother information (including changes in capacity factor) indicate a significant change in the projected values.
This ensures that the licensees will track the accumulated fluence for the limiting beltline materials throughout the life of the plant to verify that their assumptions remain valid.
In this regard we request that you submit a re-evaluation of the RT and comparison with thepredictedvalueinanyfuturepressure-temper $[bresubmittalswhichare submitted as required by 10 CFR 50, Appendix G.
Our associated Safety Evaluation is enclosed.
Sincerely,
/s/
Peter S. Tam, Project Manager PWR Project Directorate No. 2 Division of PWR Licensing-A Office of Nuclear Reactor Regulation
