Full Severe Accident Mitigation Alternatives (SAMA) analysis submitted as part of the original License Renewal Application The SAMA evaluation process follows the conclusions of NUREG-1437 Revision 2 SAMA and severe accidents are now Category 1 issues and do not require a plant-specific evaluation A "new and significant information review" was required Concluded that no there is no new and significant information related to the SAMA analysis ER Discussion: SAMA 12
ER Lessons Learned - LR Review 13 Incorporate lessons learned from previously submitted ERs and SAMA Analyses into the NMP1 SLR ER:
Agency Consultations Alternatives SAMA Evaluations Review and incorporate applicable information into NMP1 ER based on previously submitted LR/SLR ER Requests for Additional Information (RAIs).
CEG will utilize an online SharePoint portal in support of the SLR ER audit.
Regular check-in meetings between CEG and NRC PMs to ensure alignment with current regulatory guidelines such as:
ADVANCE Act Executive Orders SRMs
- CEG will submit a high-quality application which will support efficient staff reviews Highly knowledgeable team with significant SLR experience Participation in industry working groups and meetings Industry peer reviews of SLRA Monitoring on-going applicant processes Reviews of recent applicant RAIs, RCIs and supplements
