SUBJECT:
FINAL SAFETY EVALUATION OF "BWR VESSEL AND INTERNALS PROJECT, REACTOR PRESSURE VESSEL AND INTERNALS EXAMINATION GUIDELINES (BWRVIP-03) REVISION 1"(TAC NO. M95369)
Dear Mr. Terry,
The NRC staff has completed its review of the Electric Power Research Institute (EPRI) Report TR-105696-R1, "BWR Vessel and intemals Project: Reactor Pressure Vessel [RPV] and intemals Examinations Guidelines (BWRVIP-03) Revision 1," dated March 30,1999. This report was submitted in response to the NRC staff's initial safety evaluation dated June 8,1998, regarding your initial submittal of the BWRVIP-03 report dated November 10,1995, as supplemented by letters dated April 16,1996, and March 12 and July 7,1997. The BWRVlP-03 report, as revised, proposed guidelines for NDE techniques and inspection standards intended for voluntary implementation by BWR licensees in order to effectively examine and ensure the integrity of safety related RPV internal components.
The NRC staff has reviewed the revised BWRVIP-03 report and finds, in the enclosed Safety Evaluation (SE), that the guidance of the BWRVIP-03 report is acceptable forinspection of the subject safety-related RPV intemal components. This finding is based on information submitted by the above letters. The staff has concluded that licensee implementation of the guidelines in BWRVIP-03, Revision 1, will provide an acceptable level of quality for examination of the safety-related components addressed in the BWRVIP-03, Revision 1, document. This letter also closes the open items on the BWRVIP-03 report in the staff's SE's for the following BWRVIP reports:
1 BWRVIP-18, *BWR Vessel and Internals Project, BWR Core Spray Internals inspection and
