REVIEW RESPONSIBILITIES Primary - Organization responsible for probabilistic risk assessment Secondary - Technical organizations identified in the review procedures section of this Standard Review Plan may be consulted, as needed I. AREAS OF REVIEW This Standard Review Plan (SRP) section provides the staff guidance on how to perform safety reviews of the reliability assurance program (RAP) description in design certification (DC) and combined license (COL) applications. The RAP should be implemented according to the recommendations of SECY-95-132, Item E, “Reliability Assurance Program” (May 22, 1995), approved by the Commission in the staff 17.4-2 Draft Revision 1 – May 2013 requirements memorandum (SRM) to SECY-95-132 (June 28, 1995). The RAP applies to those systems, structures, and components (SSCs), both safety-related and non-safety-related, identified as risk-significant (or significant contributors to plant safety). The SSCs within the scope of the RAP (referred to hereafter as "RAP SSCs") are identified by using a combination of probabilistic, deterministic, and other methods of analysis used to identify and quantify risk, including information obtained from sources such as the probabilistic risk assessment (PRA), severe accident evaluations, industry operating experience, and expert panels. The purpose of the RAP is to provide reasonable assurance of the following: • A plant is designed, constructed, and operated in a manner that is consistent with the risk insights and key assumptions (e.g., SSC design, reliability, and availability) from the probabilistic, deterministic, and other methods of analysis used to identify and quantify risk. • The RAP SSCs do not degrade to an unacceptable level of reliability, availability, or condition during plant operations. • The frequency of transients that challenge these SSCs is minimized. • These SSCs will function reliably when challenged. The RAP is implemented in two stages. The first stage, the
