SAMA
Severe Accident Mitigation Alternatives SAMA Analysis is addressed in NEI 05-01 Rev. A Severe Accident Mitigation Alternatives SAMA Analysis Guidance Document November 2005. The document provides a template for completing the SAMA analysis in support of license renewal. It identifies the info that should be in the SAMA portion of a License Renewal Application (LRA) environmental report. The method relies upon NUREG/BR-0184 regulatory analysis techniques, is a result of experience gained through past SAMA alayyses, and incorporates insights gained from review of NRC evaluations of SAMA analyses and associated RAIs.
The purpose of the analyses is to identify SAMA candidates that have teh potential to reduce severe accident risk and to determine if implementation of each SAMA candidate is cost-beneficial.
The analysis is required by 10 CFR 51.53 (c)(3)(ii)(L)
The SAMA analysis consists of the following steps:
Determine Severe Accident Risk (using plant -specific Probabilistic Safety Assessment (PSA) Model Level 1 and Level 2 output); Determine Cost of Severe Accident Risk/Maximum Benefit; SAMA Identification; Preliminary Screening (Phase I SAMA Analysis); Final Screenng (Phase II SAMA Analysis); Sensitivity Analysis; Identify Conclusions
