• The.Haterials Integrity Section of the Materials Engineering Branch, Division of Systens Safety, has evaluated the~information contained in the letter dated hovenber 5,1976,. from Mr. J. T. Rodgers, Florida

g. Power Company, in regard to ~the-integrated irradiation program for the reactor-vessel for the Crystal River Unit No. 3 plant.,

' The FSAR'for this plaat states in Section 4.4.5 that the governing criteria.for the materials ' surveillance progran is. A5 Tit E 185-70, and

- that the program will meet the intent of Appendix H,10 CFR Part 50.

' Insufficient info'rmation is presentsd in Tables 1 and 2 of the subhct

~

letter for. the liaterials Enuineering Branch to detemine whether the suggested a;proach tests the requirements of Appendix H.

We. reouire that all specimens _in'the capsules be identified; and their identity be related to the material in the Crystal = River Unit No. 3 reactor vessel beltlins region. 0f course, specimen location should also be identified in relation to the> fracture toughness requirement of Apcendix G,.10 CFR-Part 50,:and Appendix G of the'ASME.. Code. The withdrawal; schedule of the capsules in compliance with Appendix li should be related to the f '

irradiation. dosage and the anticipated shift in,RT dur.ing. the. life off NDT the Crystal River Unit No. 3 reactor. vessel.
