SUMMARY

OF PUBLIC MEETING ON SAFETY EVALUATION REPORT WITH OPEN ITEMS REGARDING THE WOLF CREEK GENERATING STATION LICENSE RENEWAL REVIEW (TAC NO. MD3181)

On Thursday, May 1, 2008, members of the U.S. Nuclear Regulatory Commission (NRC) staff held public meetings in the Executive Boulevard Building in Rockville, Maryland, to discuss the status of the safety evaluation of the license renewal application submitted by Wolf Creek Nuclear Operating Corporation (WCNOC).

This was a category 1 public meeting. The public was invited to observe this meeting and had one or more opportunities to communicate with the U.S. Nuclear Regulatory Commission (NRC) staff after the business portion, but before the meeting was adjourned. One representive from the Strategic T eaming and Resource Sharing (STAR) alliance (an owner group) was present to observe the meeting. There was also a call-in observer from the Vogtle license renewal applicant. No member of the public chose to participate in the meeting.

Enclosure 1 provides a listing of the participants attending the meeting. Enclosure 2 is a copy of the meeting handouts (copy of slide presentation) presented by the WCNOC staff. Enclosure 3 is the meeting agenda. A summary of the discussion during the meeting is as follows:

1. Status of SER open items

The SER has three open items related to metal fatigue analysis. The response for the open items was scheduled for May 15, 2008. The purpose of the May 1, 2008 meeting was to discuss the status of the information to be submitted on May 15, 2008 for closure of the metal fatigue analysis open items. Of the three open items, one requires the staff confirmation of inputs and assumptions of supporting calculations for the metal fatigue analysis. This will be performed by the staff prior to closure of the SER open items and before the issuance of the final SER.

Issuance of the SER is scheduled for July 29, 2008.

2. Information expectation for the May 15, 2008 submittal

In the LRA, the applicant uses the Green's function approach to calculate the Cumulative Usage Factors (CUFs) for hot leg surge line nozzle and the charging nozzles. The staff is concerned that this approach may not be conservative. Therefore, the staff expects the applicant to submit an ASME Section III, Subsection NB-3200 analysis along with the Green's f unction approach analysis for comparison. The staff expects that these analyses will contain sufficient information

2 such that a comparison on the transients, F en value, and locations can be made. In addition, the staff expects both of these analysis approaches to reflect:

  • Current plant configuration (presence of thermal sleeve for the charging nozzle)
  • all of plant operating history (accounting CUF accumulated prior to implementation of modified operating procedure for the surge line nozzle).

WCNOC staff stated that a confirmation of the thermal-sleeve configuration would be performed.
