The following issues were discussed during the telephone conference call:
RAI 3.6.2.2-N-01-1 10CFR 54.21(a)(3) requires an applicant to demonstrate that the effects of aging, of components such as cable connections defined in 10CFR 54.21(a)(1), will be adequately managed so that the intended function(s) will be maintained consistent with the current licensing basis for the period of extended operation. To demonstrate that the effects of aging will be adequately managed for license renewal, the staff has asked applicants to identify the program relied upon to manage certain aging effects for cable connections. An aging management program (AMP) for cable connections acceptable to the staff is described in Generic Aging Lessons Learned Report (GALL) AMP XI.E6. The AMP states that this aging management program for electrical cable connections (metallic parts) account for the following aging stressors: thermal cycling, ohmic heating, electrical transients, vibration, chemical contamination, corrosion, and oxidation.
Therefore, the staff requests that the applicant either provide a plant-specific AMP with the AMP elements found in the Standard Review Plan for Review of License Renewal Applications for Nuclear Power Plants (SRP-LR), Appendix A.1, Section A.1.2.3 and SRP-LR Table A.1-1, or an AMP consistent with GALL AMP XI.E6. If the applicant maintains that an AMP is not required, the applicant is requested to explain in detail how the existing program will address the above aging effects and provide a detailed discussion of how each of the ten elements of aging management, as described in the SRP-LR sections mentioned above, is met by the current program. Also, the applicant is requested to provide supporting documentation to show that the aging management program elements, including appropriate tests, are implemented currently and will be continued for the extended period of operation.
Discussion: The applicant agreed to submit a XI.E6 program based on the discussion and decision made during the November 30, 2006, meeting with the Nuclear Energy Institute. The staff will evaluate the program upon its submittal.
RAI 3.6.2.2-N-08-2 Electrical components for the Vernon Hydroelectric Station (VHS) include 2 black-start turbine generators, cables and buses for power transmission, instrumentation and control components and their associated cables and connections. The audit team found that there is an AMP for underground cables from the Vernon dam tie breaker routed to Vermont Yankee. However, there appears to be no AMPs for electrical components from the tie breaker to the VHS generators. Please describe how aging effects on the rest of the electrical components will be managed during the period of extended operation.
Discussion: The applicant first addressed this RAI in their October 20, 2006, letter (License Renewal Application, Amendment 17). The staff did not agree with the applicants methodology used in that response. The staff clarified its position during the call. The applicant will provide a revised response to this concern in a future letter to the NRC.
RAI 3.6.2.2-N-08-4 The applicant stated that VHS switchyard passive long-lived commodity groups are effectively maintained through routine maintenance by the switchyard owner. Describe how this routine maintenance will manage the aging effects on the VHS switchyard passive long-lived commodity groups during the period of extended operations.
Discussion: The applicant first addressed this RAI in their October 20, 2006, letter (License Renewal Application, Amendment 17). The staff did not agree with the applicants methodology used in that response. The staff clarified its position. The applicant will provide a revised response to this concern in a future letter to the NRC.
RAI 3.6.2.2-N-08-5 Address the following station blackout alternate alternating currents (SBO AAC) related items:
- a.
Please describe (as stated in GALL AMP XI.E6) how aging effects are managed so that the intended function of cable connections associated with SBO AAC (including VHS) will be maintained during the extended period of operation.
Discussion: The applicant first addressed this RAI in their October 20, 2006, letter (License Renewal Application, Amendment 17). The staff did not agree with the applicants methodology used in that response. The staff clarified its position. The applicant will provide a revised response to this concern in a future letter to the NRC.
RAI 4.3-H-1 In the basis document for the fatigue monitoring program, a 100EF/hour heatup/cooldown rate was identified for normal transient conditions. The actual operating condition for heatup and cooldown rate is 100EF when averaged over any one hour period. Therefore, the actual operating condition may result in a much higher rate than 100EF/hour. For example, a 60EF temperature change for a 0.1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> period represents a 600EF/hour rate. Thermal stress is a function of the rate of temperature difference. The higher the rate, the higher the stress.
Please describe how VYNPSs automatic cycle counting program will adequately define the transients and cycle numbers. Please provide description to ensure the fatigue cumulative usage factor and thermal stress are evaluated in accordance with the actual transients or enveloped the actual transient.
Discussion: The staff requested the applicant provide actual numbers for design cycles versus transients. The applicant agreed to provide the requested numbers in a supplemental response to this concern in a future letter to the NRC.
