RAI A1-2 Follow-up on Operating Experience Implementation (3.0.5)
Back~ground By letter dated June 14, 2012, STP Nuclear Operating Company (STPNOC or the applicant) revised license renewal application (LRA) Section Al, which is part of the updated final safety analysis report (UFSAR) supplement, to provide a more detailed description of how operating experience will be reviewed on an ongoing basis to address operating experience concerning age-related degradation and aging management during the terms of the renewed licenses.
This summary description identifies several enhancements that will be made to the existing Operating Experience Program and the Corrective Action Program.
Issue LRA Section A4 describes the license renewal commitments and is also part of the UFSAR supplement. Commitment No. 41, as revised by letter dated June 14, 2012, addresses the enhancements that will be made to the Operating Experience Program and the Corrective Action Program and states that they will be implemented by December 31, 2014. LRA Section Al describes the same enhancements but does not state an explicit implementation schedule.
Therefore, the staff is unclear with respect to the applicant's intended implementation schedule.
In addition, the staff's position, as described in Final License Renewal Interim Staff Guidance, LR-ISG-2011-05, "Ongoing Review of Operating Experience," is that any enhancements to the existing operating experience review activities should be put in place no later than the date the renewed operating licenses are issued and implemented on an ongoing basis throughout the terms of the renewed licenses. The December 31, 2014, implementation schedule could be after issuance of the renewed operating licenses. As such, it is not clear how operating experience on age-related degradation and aging management will be considered during the terms of the renewed operating licenses prior to full implementation of the enhancements.
Request Clarify the UFSAR supplement regarding the implementation schedule for the enhancements that will be made to the Operating Experience Program and the Corrective Action Program. If implementation will be after issuance of the renewed operating licenses, provide a justification and include any relevant practical considerations that would impact the implementation timeframe.
