REVIEW RESPONSIBILITIES Primary - Organization responsible for probabilistic risk assessment Secondary - Technical organizations identified in the review procedures section of this Standard Review Plan (SRP) may be consulted, as needed I. AREAS OF REVIEW This 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, “Policy and Technical Issues Associated with the Regulatory Treatment of Non-safety Systems (RTNSS) in Passive Plant Designs,” Item E, “Reliability Assurance Program” (May 22, 1995),approved by the Commission in the staff requirements memorandum (SRM) to SECY-95-132 (June 28, 1995). The RAP applies to those systems, structures, and components (SSCs), both safety-related and nonsafety-related, identified as risk-significant (or significant 17.4-2 Revision 1 – May 2014 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 to identify and quantify risk, including probabilistic risk assessment (PRA), severe accident evaluation, assessment of industry operating experience, and expert panel deliberation. 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
