REVIEW RESPONSIBILITIES Primary - Organization responsible for the review of instrumentation and controls Secondary - None 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 criteria, guidelines and performance requirements. 1. This Standard Review Plan (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. 7.3-2 Revision 5 - March 2007 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 provides the review criteria for the information systems important to safety, which inclues instrumentation tht indicates the need for manual initiation and control of ESF systems. Examples of ESF systems, Auxiliary Supporting Features and Other Auxiliary Features are as follows: Typical ESF systems are: A. Containment and reactor vessel isolation systems. B. Emergency core cooling systems. C. Containment heat removal and depressurization systems. D. Pressurized water reactor auxiliary feedwater systems. E. Emergency boration systems. F. Boiling water reactor standby gas treatment systems. G. Containment air purification and cleanup systems. H. Containment combustible gas control systems. I. Control room isolation and emergency heating, ventilating, and air conditioning (HVAC). Typical auxiliary
