Dear Mr. Terry:
The NRC staff has completed its review of the Electric Power Research Institute (EPRI) proprietary report TR 108726 *BWR Vessel and Internals Project, LPCI Coupling Inspection and Flaw Evaluation Guideline (BWRVIP-42)." This report was submitted by letter dated December 11,1997, and was supplemented by letter dated September 8,1998. It provides generic guidelines intended to present the appropriate inspection recommendations to ensure safety function integrity of the subject safety-related low pressure coolant injection (LPCI) couplings.
The staff has reviewed the BWRVIP-42 report and finds that, in the enclosed safety evaluation (SE), the guidance of the BWRVIP-42 report acceptable for inspection and flaw evaluation of the subject safety-related reactor pressure vessel (RPV) internal components, except where the l staff's conclusions differ from the BWRVIP's, as discussed in the enclosed SE. The staff has !
concluded that the licensee implementation of the guidelines in the BWRVIP-42 report will provide an acceptable level of quality for inspection and flaw evaluatim 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 revised BWRVIP-42 report. Please inform the staff within 90 days of the date of this letter of your proposed actions and schedule for revisions.
Please contact C. E. (Gene) Carpenter, Jr., of my staff at (301) 415-2169, if you have any further questions regarding this subject.
