REVIEW RESPONSIBILITIES Primary - Organization responsible for the review of instrumentation and controls Secondary - None Review Note: The revision numbers of Regulatory Guides (RG) and the years of endorsed industry standards referenced in this Standard Review Plan (SRP) section are centrally maintained in SRP Section 7.1-T (Table 7-1). Therefore, the individual revision numbers of RGs (except RG 1.97) and years of endorsed industry standards are not shown in this section. References to industry standards incorporated by reference into regulation (IEEE Std 279-1971 and IEEE Std 603-1991) and industry standards that are not endorsed by the agency do include the associated year in this section. See Table 7-1 to ensure that the appropriate RGs and endorsed industry standards are used for the review. I. AREAS OF REVIEW The objective of the review is to confirm that the engineered safety features actuation system (ESFAS) and engineered safety features (ESF) control systems satisfy regulatory acceptance 7.3-2 Draft Revision 6 – August 2015 criteria, guidelines and performance requirements. 1. This SRP section describes the review process and acceptance criteria for the ESFAS, which is a portion of the protection system used to initiate the ESF systems and auxiliary supporting features and other auxiliary features. The ESFAS provides both automatic and manual initiation of these systems. This SRP section also includes the review criteria for control systems that regulate the ESF systems. The ESF control systems include both the automatic and manual features. The specific areas of review are as follows: The review of instrumentation and control systems that regulate the operation of auxiliary supporting features and other auxiliary features is included in the SRP sections that address systems that implement those features. SRP Section 7.5, “Information Systems Important to Safety,” provides the review criteria for the information systems important to safety, which
