January 23, 1984 Docket Nos. 50-259 50-260 and 50-296 Mr. Hugh G. Parrfs Manager of Power Tennessee Valley Authority 500 A Chestnut Street, Tower II Chattanooga, Tennessee 37401
Dear Mr. Parrfs:
SUBJECT:
REACTOR VESSFL PRESSURE-TEMPERATURE CURVES Re:
Browns Ferry Nuclear Plant, Units 1, 2, and 3
Your submfttals of July 21, 1983=(TS 178 Sup.
- 1) and September 22, 1983 (TS 191) requested changes to the Browns Ferry technical specifications to provfde reactor vessel pressure-temperature curves for sfx effective full
'ower years and for the vessel end-of-life, respectively.
Additional information regardfng the predicted end-of-life neutron fluence, the chemical composition and charpy impact test results for the reactor vessel surveillance materfals was provided in your letter of October 19, 1983.
This subject was also discussed with your staff fn a telecon on NoVember 30, 1983.
The length of time a pressure-temperature curve fs effective depends upon the amount of neutron irradiation damage that fs predicted to occur for the limiting reactor vessel beltlfne material.
The survefllance material data provided by your submfttals fs not sufficient to determine pressure-temperature curves for the Browns Ferry pressure vessels because you have not provided the necessary materfals data to verffy'that the surveillance material fs representative of the beltline materfal.
Your proposed pressure temperature curves are based upon the predicted in-crease fn reference temperature for the reactor vessel surveillance mate-rial.
Therefore, we request that you either revise the pressure tempera-ture curves using conservative assumptions'op.
reactor vessel beltline material fracture toughness and chemical composition or demonstrate that the predicted neutron irradiation damage for the reactor vessel beltlfne materials will be less than that predicted for the reactor vessel survefl-lance material. If you choose the latter, you must provide for each reactor vessel beltline material:
