SUMMARY

OF THE JUNE 12 - 13,1997, MEETING WITH SARGENT & LUNDY TO DISCUSS THE ICAVP SYSTEM BOUNDARIES FOR SELECTED SYSTEMS l

FOR MILLSTONE UNIT 3 On June 12 and 13,1997, the Special Project Office (SPO) staff of the Office of Nuclear Reactor Regulation (NRR) participated in a publicly observed meeting with Sargent & Lundy (S&L) representatives. The purpose of this meeting was to discuss the Independent Corrective Action Verification Program (ICAVP) system boundaries for the Service Water (SW), Quench Spray (OSS), and Recirculation Spray (RSS) systems to be reviewed by S&L during the Tier 1 vertical slice system review at Millstone Unit 3. Also, the staff and S&L discussed the scope and depth of the Tier 2 accident analysis reviews, and how to disposition items on Northeast l

Utilities corrective action / unresolved issues records (CR/UIR) lists that are of low safety significance or related to minor maintenance issues. provides a list of the attendees at the meeting. Enclosure 2 provides the handout used by S&L as the outline for discussions during the meeting with the NRC. No handouts were used during the discussions on the scope and depth of the Tier 2 accident analysis reviews and how S&L should disposition minor issues on the licensee's CR/UIR lists. The staff found that the scope and depth of the Tier 2 accident analysis review proposed by S&L were consistent with the NRC's expectations and its approved audit plan, and noted that S&L's Tier 2 review would be further assessed during the NRC's ICAVP implementation inspection to be conducted in the future. The staff indicated to S&L that the scope of its review of the minor issues on the licensee's CR/UIR lists should include verifying that the issues are not safety significant individually or when considered with other similar issues (generic or repetitive issues), and do not represent a change to the licensing bases of Unit 3.
