n certification will enhance safety by concentrating design resources on risk- significant SSCs and on maintaining the reliability of such SSCs during the design and operations stages of the facility. Meeting the requirements for a RAP as outlined in SECY 95-132 for standard design certifications or for COL applicants that reference a standard design certification provides assurance that the proposed plant will perform with the reliability required to ensure that no undue risk is posed to the health and safety of the public. It will also provide assurance that (a) the plant design is consistent with the assumptions and potential risks associated with risk-significant SSCs, (b) risk-significant SSCs will not degrade to an unacceptable level during their design life, (c) the frequency of transients that challenge these SSCs will be acceptably low, and (d) SSCs will function reliably when challenged. 2. Compliance with 10 CFR 50.65 requires that operators of nuclear power plants monitor the performance and condition of SSCs to provide reasonable assurance that specified SSCs are capable of fulfilling their intended functions. Requirements specified in 10 CFR 50.65 apply to this SRP section because operational reliability assurance activities should be integrated into such programs (e.g., maintenance, surveillance, inservice inspection, inservice testing, and quality assurance). For maintenance, reliability performance goals for risk-significant SSCs are ensured by using the existing maintenance process. The licensee will establish performance, condition monitoring, and preventive maintenance requirements to provide reasonable assurance that the reliability of risk-significant SSCs is either maintained or is not unacceptably degraded throughout their service life. Regulatory Guide 1.160 provides guidance, acceptable to the staff, for implementation of the maintenance rule. Meeting the requirements specified in 10 CFR 50.65 provides assurance that plant SSCs will be
