Subject:
Oconee Nuclear Station Docket Nos. 50-269, -270, -287 Gentlemen:
Pursuant to 10 CFR 50, Appendix H, please find attached two reports, BAW-2050 dated October, 1988 and BAW-2051 dated October, 1988 on the testing and evaluation of capsules OCI-C and OCII-E for Oconee Nuclear Station Units 1 and 2 reactor vessel material surveillance program, respectively.
The reports' major results are summarized below:
- 1. The OCI-C and OCII-E capsules received an average fast fluence (E >1.0 18 2
19 2
Mev) of 9.86 x 10 n/cm and 1.21 x 10 n/cm, respectively. Based on the calculated fast flux at the vessel wall, an 80% load factor, and the planned fuel management, the projected fast fluence that the Oconee Units 1 and 2 reactor vessel inside surface will receive in 40 calendar years 19 2
18 2
of operation is 1.02 x 10 n/cm and 9.57 x 10 n/cm, respectively.
- 2. The increase in RTNDT for both forging and weld materials is conservative with respect to prediction technique, i.e. R.G. 1.99, Rev.
- 02.
- 3. The low upper-shelf energy fracture analysis demonstrated that the most limiting weld metal has adequate irradiated toughness properties to assure safe operation of these units to 32 EFPY.
