DRAFT REQUESTS FOR ADDITIONAL INFORMATION WOLF CREEK GENERATING STATION, UNIT 1 LICENSE RENEWAL APPLICATION APRIL 06, 2007 The U.S. Nuclear Regulatory Commission (NRC or the staff) and representatives of Wolf Creek Nuclear Operating Corporation held a telephone conference call on April 06, 2007, to discuss and clarify the following draft requests for additional information (D-RAIs) concerning the Wolf Creek Generating Station (WCGS), Unit 1, license renewal application (LRA).
AGING MANAGEMENT REVIEW Aging Management of Reactor Vessel, Internals, and Reactor Coolant System D-RAI 3.1.2.2.3-1 LRA Section 3.1.2.2.3-1 states that since beltline materials remain limiting, nozzles were not evaluated separately. In accordance with 10 CFR Part 50, Appendix H, Section III, if the end of life (EOL) peak neutron fluence exceeds 1017 n/cm2 (E > 1 MeV) the material must be monitored through a surveillance program. The staff requests that the applicant confirm that the increase in peak 60-year EOL fluence for the nozzles will not exceed this value. The staff requests that the applicant provide appropriate data for the inclusion of nozzle materials in the surveillance program, or explain how the nozzle materials are adequately monitored by the proposed aging management program.
Discussion: The applicant indicated that the question is clear. This D-RAI will be sent as a formal RAI.
TIME-LIMITED AGING ANALYSIS Neutron Fluence, Upper Shelf Energy and Adjusted Reference Temperature D-RAI 4.2.1-1 The staff requests that the applicant submit a table of the 60-year EOL upper shelf energy (USE) values for each beltline material. The heat numbers, material ID, copper content (weight-percent), initial USE, EOL 1/4 T fluence and the EOL 1/4 T USE should be included. In addition, the staff requests that the applicant discuss how surveillance results were evaluated in the determination of the USE values.
Discussion: The applicant indicated that the question is clear. This D-RAI will be sent as a formal RAI.
Enclosure 2
Pressurized Thermal Shock D-RAI 4.2.2-1 The staff requests that the applicant submit a table of the 60-year EOL reference temperature for pressurized thermal shock (RTPTS) values for each beltline material. The heat numbers, material ID, copper and nickel content (weight-percent), chemistry factor, initial RTNDT, margin, EOL peak fluence, fluence factor, RTPTS, and EOL RTPTS values should be included. In addition, the staff requests that the applicant discuss how surveillance capsule results were applied in the determination of the RTPTS values.
Discussion: The applicant indicated that the question is clear. This D-RAI will be sent as a formal RAI.
