' U.S. Nuclear Regulatory Commission ATTN: Document Control Desk Washington,DC 20555 Joseph M. Farley Nuclear Plant Generic Letter 92-01 Request For Addiliqui Information Regarding Reactor Vessel Integrity

. Ladies and Genti: men:

By letter daied April 3,1998; the NRC Staffissued a request for additional information

' concerning reactor pressure vessel integrity at the Joseph M. Farley Nuclear Plant. The focus of the request for additional information was the impact of Combustion Engineering Owners' Group report CE NPSD-1039, Revision 2, ."Best Estimate Copper and Nickel Values in CE Fabricated Reactor Vessel Welds," dated June 1997. In part, the letter states, "In July 1997, the Combustion Engineering Owners' Group (CEOG) provided a report with additional RPV

- weld chemistry data for RPVs fabricated by' CE. This additional RPV weld chemistry data may affect previous RPV integrity anslyses supplied by licensees with CE fabricated RPVs. j

-If a question does not apply to your situation, please indicate this in your RAI response along '

- with your technical basis.' ..".

In the same time frame as the request for additional information, the NRC Staff approved a -

technical specification amendment for Farley Nuclear Plant for application of a prescure

- temperature limits report (PTLR). As was stated in Southern Nuclear's letter dated December 18,1997, the best estimate copper and nickel values determined by the gU -  ;

Combustion Engineering Owners' Group were used in developing the PTLR. Consequently,

.
the focus of the request for additional information is not applicable to Farley Units 1 and 2 i since the CEOG best estimate values were used to develop the pressure temperature limits.

This position was confirmed with members of the NRC Staff by conference call on May 15, r-1998.

. h'){

L The PTLRs for Farley Units 1 and 2 were submitted to the NRC Staff by letter dated May 19,1998. The PTLRs along with the Combustion Engineering Owners' Group report CE NPSD-1039, Revision 2, ."Best Estimate Copper and Nickel Values in CE Fabricated Reactor

Vessel Welds," dated June 1997, provide the information requested.
