ENCLOSURE '

Crystal River 3 (TAC Nn, M83731)

Question 2a in GL 92-01 i

The response to GL 92-01 indicates that the end-of-life (E0L) upper-shelf energy (USE) value for the limiting weld WF-70 will fall below the screening criterion of i 50 ft-lb. An owners group report on USE equivalent margin analysis regarding i beltline welds with low USE values for Levels A & B is under preparation by the  :

Babcock & Wilcox Owners Group (BWOG); a similar BWOG report for Levels C & D (BAW-2178P) is under NRC review now. The licensee must confirm that these two topical ,

reports will be used as its licensing bases to demonstrate that all beltline welds  !

will meet the USE requirements of Appendix G,10CFR 50. -

Question 2b in GL 92-01 The response indicates that a generic initial RT 7 of -5 F, which is the mean RT value for 34 Linde 80 welds (BAW-1803, Revision 1), has been used for all wefdsexcepttheweldWF-70. Provide justification for not using the generic mean value for Linde 80 welds of 0 F as required by 10 CFR 50.61.
