REVIEW RESPONSIBILITIES Primary ' Instrumentation and Control Systems Branch (ICSB) Secondary - None I. AREAS OF REVIEW This SRP section describes the review for the portion of the protection system used to initiate the operation of the engineered safety features (ESF) systems and essential auxiliary supporting (EAS) systems. This portion of the protection system is called the engineered safety features actuation system (ESFAS). The ESFAS includes both automatic and manual initiation of these systems. This SRP section also includes the review of-control systems which regulates the operation of ESF systems following their initiation by the protection system. The ESF control systems include both the automatic and manual features which control the operation of ESF systems. The review of instrumentation and control .systems for EAS systems is included in the SRP sections which address these systems. SRP Section 7.5 includes the information systems important to safety that provide information which is used to indicate the need for manual initiation and for the manual control of ESF systems. The functional performance requirements of ESF and EAS systems are reviewed by other branches in accordance with the SRP sections which address these systems. The accident analysis described in Chapter 15 of the SAR establishes the bases for monitored variables and the values of monitored variables including asso- ciated time delays used to initiate protective system actions. The review verifies that the functional performance requirements of the ESFAS satisfy the design bases for the protection system actions consistent with the accident analysis described in Chapter 15. The objectives of the review are to confirm that the ESFAS satisfies the requirements of the acceptance criteria and guidelines applicable to the protec- tion system and will perform its safety function during all plant conditions for Rev. 2 - July 1981 USNRC STANDARD REVIEW PLAN Standard review plans are prepared
