U TELECON MEMO TO:

J. T. Rodgers, Florida Power Corporation FROM:

L. B. Engle, NRC DATE:

November 12, 1976 This is not yet official, but I understand what is being transmitted to you will be official next week. I am giving it to you so you can begin to react immediately,

SUBJECT:

Material Specimen Surveillance Program for Reactor Vessel.

Surveillance Specimens for Crystal River Unit #3 The Material Ingegrity Section of the' Materials Engineering Branch Division of System Safety has evaluated the information contained in the letter dated November 5,1976, from Mr. J. T. Rodgers, Florida Power Corporation, in regard to your integrated irradiation program for the Reactor Vessel for the CR#3 Plant.

The FSAR for this plant states in Section 4. 4. 5 that the ' governing criteria for the material surveillance program is ASTM E-185-70 and that the program will meet the intent of Appendix H 10CFR, Part 50.

Insufficient information is presented in Table 1 and 2 of the subject letter for the Materials Engineering Branch to determine whether the suggested approach meets the requirements of Appendix H.

We require that all specimens in capsules be identified and their identity be related to the materials in CR#3 Reactor V_essel belt line region. Specimen location should also be identified in relation to the fracture toughness re-quirement of Appendix G,10CFR, Part 50, and Appendix G, of the ASME

~

Code.

The withdrawal schedule of the capsules in compliance with Appendix H should be related to the irradiation dosage and the anticipated shift in RT during the life of the CR#3 Reactor Vessel.
