Dear Mr. Parrish:

On May 19, 1995, the U.S. Nuclear Regulatory Commission (NRC) issued Generic Letter 92-01, Revision 1, Supplement 1 (GL 92-01; Rev. 1, Supp. 1), "Reactor Vessel Structural Integrity,"

to holders of nuclear operating licenses.'n issuing the GL the staff required addressees of the GL to:

(1) identify, collect and report any new data pertinent to the analysis of structural integrity of the reactor pressure vessels (RPVs) at their nuclear plants, and (2) to assess the impact of that data on their RPV integrity analyses relative.to the requirements of Sections 50.60 and 50.61 to Part 50 of Title 10 of the Code ofFederal Regulations (10 CFR 50.60 and 10 CFR 50.61), and to the requirements of Appendices G and H to Part 50 of Title 10 of the Code ofFederal Regulations (Appendices G and H to 10 CFR Part 50).

On August 16, 1995, you submitted your initial response to GL 92-01, Rev. 1, Supp. 1. and provided the requested information relative to the structural integrity assessment for WNP-2.

The staff evaluated your response to GL 92-01, Rev. 1, Supp. 1, and provided its conclusion relative to your response on August 22, 1996.

However, since the time of the staffs closure letter, the Combustion Engineering (CE) Owners Group and the Babcock and Wilcox (B&W)

Owners Group have each submitted additional data regarding the alloying-chemistries of beltline welds in CE and B8W fabricated vessels.

The additional alloying data were submitted in Topical Reports CE NPSD-1039, Revision 2, CE NPSD-1119, Revision 1, for CE fabricated RPV welds, and BAW-2325, Revision 1, for B&Wfabricated RPV welds.

In addition, Chicago Bridge and Iron (CB8 I) BWR data were submitted in Topical Report BWRVIP-46. As a result of the efforts by CE and B&W, the staff determined that additional information was necessary relative to the structural integrity assessments for your plant. On May 14, 1998, the staff issued a request for additional information (RAI) in regard to the alloying chemistries of beltline welds, your assessment of surveillance data for your facility, pressure-temperature (P-T) limits, and pressurized thermal shock (PTS) assessments (only applicable to PWRs) for WNP-2.

In general, with respect to the contents of the RAI, the staff requested that you reassess the "P~

You provided your response to the staff's RAI for WNP-2 on August 12, 1998. As a result of the staffs review of your responses to GL 92-01, Revision 1, GL 92-01, Rev. 1, Supp. 1, and the

Supp, 1 RAI, the staff has revised the information in the Reactor Vessel Integrity Database (RVID)and is releasing it as RVIDVersion 2.

The new database diskettes are posted on the world-wide-web at a location which is linked to the NRC home page (http://www.nrc.gov/NRR/RVID/index.html ). We recommend that you

. review this information. Ifthe staff does not receive comments by September 1, 1999, we will assume that the data entered into the RVID are acceptable for your plant.

No additional information is necessary with regard to the structural integrity assessments.

Future submittals on P-T limits, PTS (only applicable to PWRs), or upper shelf energy (USE) should reference the most current information.

This closes the staffs efforts in regard to TAC No. MA1213. The staff appreciates your efforts in regard to this matter.
