i SUPPLEMENT 1, "REACTOR VESSEL STRUCTURAL INTEGRITY" (TAC NO.

MA0560)

Dear Mr. Haskell:

On May 19, 1995, the U.S. Nuclear Regulatory Commission (NRG) 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. The NRG issued the supplement to require addressees 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) 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 of Federal Regulations (10 CFR 50.60 and 10 CFR 50.61), and to the requirements of Appendices G and H to Part 50 of Title 1 O of the Code of Federal Regulations (Appendices G and H to 1 O CFR Part 50).

On August 17,

• 1995, you submitted your initial response to GL 92-01, Rev. 1, Supp. 1 and provided the requested information relative to the structural integrity assessments for the Palisades Plant. The NRG staff evaluated your response to GL 92-01, Rev. 1, Supp. 1, and provided its conclusion relative to your response on December 23, 1996. However, since the issuance of the staff's closure letter, the Combustion Engineering (CE) Owners Group and the

~()\\

J) *.

• Babcock and Wilcox (B&W) Owners Group have each submitted additional data regarding the alloying chemistries of beltline welds in CE-and B&W-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&W-fabricated RPV welds). In addition, Chicago Bridge arid Iron (CB&I) boiling-water reactor (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 June 8, 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 for the Palisades Plant. In general, with respect to the contents of the RAI, the staff requested that you reassess the alloying chemistries for the beltline welds and RPV surveillance welds relative to the chemistries provided in the applicable topical report, and provid.e the impact of any changes to the best-estimate chemistries for your beltline RPV welds 9909200227 990915 PDR ADOCK 05000255 p

You provided your response to the staff's RAI for the Palisades Plant on September 8, 1998.

As a result of the staff's review of your responses to GL 92-01, Revision 1, GL 92-01, Rev. 1, Supp. 1, and the RAI, the staff has revised the information in the Reactor Vessel Integrity Database (RVID) and is releasing it a13 RVID Version 2.
