| | REQUESTS FOR ADDITIONAL INFORMATION WOLF CREEK GENERATING STATION, UNIT 1 LICENSE RENEWAL APPLICATION AUGUST 17, 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 August 17, 2007, as a followup discussion and request for clarification to the applicants response to the following requests for additional information (RAIs) concerning the Wolf Creek Generating Station (WCGS), Unit 1, license renewal application (LRA). The applicants response to these RAIs was submitted by letter dated July 26, 2007. |
| | RAI B.2.1.34-1 The Nickel Alloy Aging Management Program (AMP) was submitted prior to the performance of pre-mitigation weld inspections for the application of weld overlays on pressurizer connections with dissimilar metal butt welds at WCGS. The pre-mitigation inspection performed in 2006 identified extensive circumferential cracking at three dissimilar metals welds associated with surge, relief, and safety nozzles. The staff requests that the applicant revise this AMP to incorporate information pertaining to the dissimilar metals butt weld inspection activities and findings. The revised AMP should: (1) discuss program enhancements incorporated as a result of the inspections, (2) provide information regarding the mitigation and preventive actions, taken or planned, to reduce the susceptibility of Alloy 600/82/182 components to primary water stress corrosion cracking (PWSCC), (3) discuss the inspection frequency and method of inspection of components susceptible to PWSCC covered under the scope of this program, and (4) provide justification that the AMP will provide reasonable assurance that PWSCC will be detected on a timely manner. |
| | In addition, the staff requests that the applicant update the AMP Updated Safety Analysis Report (USAR) supplement to reflect all changes made to the program. |
| | Discussion: Based on the discussion with the applicant, the staff indicated that the response to this RAI requires clarification. The staff requested that the applicant address the following: |
| | (1) The staff indicated that the applicants response did not address the steam generator primary nozzle and safe ends. The staff requested that the applicant address this Aging Management Review (AMR) line item. |
| | The applicant indicated that the steam generator primary nozzle and safe ends AMR line items will be modified to provide a clarification. |
| | (2) The staff requested that the applicant clarify if WCGS has Alloy 600 components in the instrumentation nozzles. |
| | The applicant indicated that WCGS only has Alloy 600 in the control rod drive mechanism. The applicant indicated that a footnote will be added to the RAI response to provide a clarification. |

REQUESTS FOR ADDITIONAL INFORMATION WOLF CREEK GENERATING STATION, UNIT 1 LICENSE RENEWAL APPLICATION AUGUST 17, 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 August 17, 2007, as a followup discussion and request for clarification to the applicants response to the following requests for additional information (RAIs) concerning the Wolf Creek Generating Station (WCGS), Unit 1, license renewal application (LRA). The applicants response to these RAIs was submitted by letter dated July 26, 2007.
RAI B.2.1.34-1 The Nickel Alloy Aging Management Program (AMP) was submitted prior to the performance of pre-mitigation weld inspections for the application of weld overlays on pressurizer connections with dissimilar metal butt welds at WCGS. The pre-mitigation inspection performed in 2006 identified extensive circumferential cracking at three dissimilar metals welds associated with surge, relief, and safety nozzles. The staff requests that the applicant revise this AMP to incorporate information pertaining to the dissimilar metals butt weld inspection activities and findings. The revised AMP should: (1) discuss program enhancements incorporated as a result of the inspections, (2) provide information regarding the mitigation and preventive actions, taken or planned, to reduce the susceptibility of Alloy 600/82/182 components to primary water stress corrosion cracking (PWSCC), (3) discuss the inspection frequency and method of inspection of components susceptible to PWSCC covered under the scope of this program, and (4) provide justification that the AMP will provide reasonable assurance that PWSCC will be detected on a timely manner.
In addition, the staff requests that the applicant update the AMP Updated Safety Analysis Report (USAR) supplement to reflect all changes made to the program.
Discussion: Based on the discussion with the applicant, the staff indicated that the response to this RAI requires clarification. The staff requested that the applicant address the following:
(1) The staff indicated that the applicants response did not address the steam generator primary nozzle and safe ends. The staff requested that the applicant address this Aging Management Review (AMR) line item.
The applicant indicated that the steam generator primary nozzle and safe ends AMR line items will be modified to provide a clarification.
(2) The staff requested that the applicant clarify if WCGS has Alloy 600 components in the instrumentation nozzles.
The applicant indicated that WCGS only has Alloy 600 in the control rod drive mechanism. The applicant indicated that a footnote will be added to the RAI response to provide a clarification.
Enclosure 2
(3) The staff requested that the applicant clarify the term generator maintenance provided in the table for this RAI response.
The applicant indicated that WCGS performs generator maintenance every refueling outage. The applicant indicated that a footnote will be added to the RAI response to provide a clarification and details about the generator maintenance frequency.
(4) The staff indicated that the applicants response did not include the USAR supplement for the Nickel Alloy AMP as requested in the RAI. The staff clarified that the USAR supplement should make reference to the AMP commitment (Commitment No. 30). In addition, the staff indicated that Commitment No. 30 should be supplemented to reflect the same language established in the commitment for pressure boundary nickel alloy components (Commitment No. 19).
