SUMMARY

OF OCTOBER 15, 2002, CONFERENCE CALL WITH VIRGINIA ELECTRIC AND POWER COMPANY ON THE REPLACEMENT OF THE REACTOR VESSEL HEAD AT NORTH ANNA POWER STATION, UNIT 2 On October 15, 2002, the U.S. Nuclear Regulatory Commission (NRC) staff held a telephone conference call with the staff of Virginia Electric and Power Company (VEPCO) to discuss the licensees plans to replace the reactor vessel head at North Anna Power Station, Unit 2. The list of conference call participants is attached.

The licensee stated they had developed an alternate approach they believed was the most effective method to accomplish reconciliation between the replacement French reactor vessel head and the currently installed head. Specifically, the licensee proposed the following approach:

1. reconcile the differences between the replacement reactor vessel head and the currently installed head under American Society of Mechanical Engineering (ASME) Code Section XI, and

2. any design differences that could not be reconciled under ASME Section XI would be screened under the 10 CFR 50.59 process.

The licensee stated that this proposed approach would be more appropriate as it would not be a precedent-setting licensing action that would require extensive staff review. The licensee indicated that the currently installed reactor vessel head was built to owners requirements, instead of the ASME Code, and was not N stamped. Likewise, since the French replacement head was not built to the ASME Code or N stamped, then these reactor vessel heads could be reconciled under ASME Section XI by comparing the as-built conditions for these two heads.

The staff replied that they needed to review this proposal with NRC management. Therefore, the licensee and NRC staff agreed to postpone the February 22, 2002, public meeting.

Docket No. 50-339
