Catawba Nuclear Station, Units 1 and 2 i
Docket Numbers 50-413 and -414 ;
Generic Letter 92-01, Revision 1; Verification of Data l Base Entries (TAC Nos. M83448 and M83449) l By letter dated May 25, 1994, the NRC forwarded a set of data to be used in the Reactor Vessel Integrity Database, and requested that Duke review the data for accuracy. In reviewing the data for !
Catawba, some erroneous data were discovered.
1 For Catawba Unit 1, Lower Shell Forging 04, Heat No. Ident. 527708, I the %Cu value should be 0.05. For Circ. Weld WOS, Heat No. Ident.
895075, the %Ni valun should be 0.72. The reference for both I values is WCAP-13763 (Table 1), August 1993, which was transmitted i to the NRC by letter from D. L. Rehn to Document Control Desk, dated August 12, 1993.
For Catawba Unit 2, ID Neut. Fluence at EOL value should be 2.46E19. (Reference WCAP-13875, Table 6-15, February, 1994, transmitted by letter, D. L. Rehn to Document Control Desk, March 2, 1994.) This will change the value of 1/4T fluence for upper shelf energy.
If you have any questions about these data, please call Scott Gewehr at (704) 382-7581.
