SUBJECT:
SAFETY EVALUATION OF THE *BWR VESSEL AND INTERNALS PROJECT, BWR TOP GUIDE INSPECTION AND FLAW EVALUATION GUIDELINES (BWRVIP-26)," EPRI REPORT TR-107285, DECEMBER 1996 (TAC NO.
l M97803)
Dear Mr. Terry,
The NRC staff has completed its review of the Electric Power Research Institute (EPRI) proprietary report TR-107285, "BWR Vessel and intemals Project, BWR Top Guide Inspection and Flaw Evaluation Guidelines (BWRVIP-26)," December 1996. This report was submitted by letter dated December 27,1996, and supplemented by letter dated December 19,1997, which was in response to the staff's request for additional information, dated March 14,1997.
The BWRVIP-26 report provides generic guidelines intended to present the appropriate inspection recommendations to assure safety function integrity of the subject safety-related RPV intemal components. The report also provides design information on the top guide, geometries, weld locations, and potential failure locations for the several categories of boiling water reactors (BWR/2 through BWR/6).
The staff has reviewed the BWRVIP-26 report and finds, in the enclosed Safety Evaluation (SE), that the guidance of the BWRVIP-26 report is acceptable forinspection and flaw evaluation of the subject safety related RPV intemal components, except where the staff's conclusions differ from the BWRVIP's, as discussed in the enclosed SE. The staff has concluded that licensee implementation of the guidelines in the BWRVIP 26 report will provide an acceptable level of quality forinspection and flaw evaluation, with modifications to address the staff's conclusions in the enclosed SE, of the safety-related components addressed.
The staff requests that the BWRVIP review and resolve the issues raised in the enclosed SE, and incorporate the staff's conclusions into the revised BWRVIP 26 report. Please inform the staff within 90 days of the date of this letter of your proposed actions and schedule for l
revisions.
