r design certification applications for the Advanced Boiling Water Reactor in NUREG-1503 and the System 80+ in NUREG-1462. The information on performance requirements for certified designs outlined in SECY 95- 132 forms the basis for requiring the RAP and is thus directly applicable to this SRP section. In NUREG-1070, "NRC Policy on Future Reactor Designs," issued in 1985, the staff discussed the use of a systems reliability program to ensure that the reliability of components and systems important to safety would remain at a level that would be commensurate with plant safety requirements. To ensure that reliability objectives are met and to prevent degradation of reliability during operation, insights into risk should be obtained from probabilistic and deterministic evaluations performed at the standard design certification application stage and at the COL application and holder stages and then used to make decisions affecting design, procurement, and testing and to formulate operations and maintenance procedures. After the publication of NUREG-1070, the staff worked to develop a coherent program that would ensure a minimum level of reliability for risk-significant SSCs. This effort culminated in the development and approval of SECY 95-132 for certified designs, providing RAP requirements to be included in applications for standard design certifications and in COL applications that reference standard design certifications. DRAFT Rev. 0 - April 1996 17.4-8 These requirements provide (a) the framework for the RAP and (b) the detailed requirements for contents of an application for a standard design certification or a COL that references a standard design certification. Implementation of a RAP for a standard design certification or a COL that references a standard design 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.
