SUBJECT:
CLOSURE OF TAC NOS. MA0579 AND MA0580 - RESPONSE TO THE REQUESTS FOR ADDITIONALINFORMATIONTO GENERIC LETTER 92-01, REVISION 1, SUPPLEMENT 1, "REACTOR VESSEL STRUCTURAL INTEGRITY,"FOR THE TURKEY POINT PLANT, UNITS 3 AND 4
Dear Mr. Plunkett:
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.
In 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 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 10 of the Code of Federal Regulations (Appendices G and H to 10 CFR Part 50).
On August 9, 1995, you submitted your initial response to GL 92-01, Rev. 1, Supp.
1 and provided the requested information relative the structural integrity assessments for the Turkey Point Plant, Units 3 and 4. The staff evaluated your response to GL 92-01, Rev. 1, Supp. 1, and provided its conclusion relative to your response on August 5, 1996.
However, since the time of the staff's 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 B&Wfabricated 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. 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 plants.
On April7, 1998, the staff issued a request for additional information (RAI) in regard to the alloying chemistries of beltline v.elds, your assessm=nt of surveillance data for your facility, pressurc-temperature (P-T) limits, and pressurized thermal shock (PTS) assessments for the Turkey Point Plant, Units 3 and 4. 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, 9'P07i50047 990708 PDR AoaCK 05000aSO P

Thomas F. Plunkett 8, 1999 and provide the impact of any changes to the best-estimate chemistries for your beltline RPV welds on the structural integrity assessments for your facilityrelative to the requirements of 10 CFR 50.60, 10 CFR 50.61, and Appendices G and H to 10 CFR Part 50, as applicable to the licensing bases for your plant.
You provided your response to the staff's RAls for the Turkey.Point Plant on July 13, 1998, As a result of the staff's review of your responses to GL92-01, Revision 1, GL92-01, 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 RVID Version 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.
If the 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 should reference the most current information.
This closes the staff's efforts in regard to TAC Nos. MA0579 and MA0580. The staff appreciates your efforts in regard to this matter.
