INTRODUCTION REVIEW RESPONSIBILITIES Primary - Instrumentation and Control Systems Branch (ICSB) Secondary - None I. AREAS OF REVIEW The instrumentation and control systems important to safety fall into the follow- ing categories and are addressed in detail in subsequent sections of Chapter 7 or other sections of the safety analysis report (SAR). Protection Systems are those instrumentation and control systems which initiate safety actions to mitigate the consequences of design basis events. The protec- tion systems include the Reactor Trip System (RTS) discussed in Section 7.2 and the engineered safety features actuation system (ESFAS) discussed in Section 7.3 of the SAR. Engineered Safety Features (ESF) Control Systems are those control systems which regulate the operation of ESF systems following their initiation by the protec- tion system. The ESF control systems are discussed in Section 7.3 of the SAR. Safe Shutdown Systems are those systems which must function to achieve and main- tain a safe shutdown condition of the plant. The safe shutdown systems include those instrumentation and control systems which are used to maintain the reactor core in a subcritical condition and provide adequate core cooling to achieve and maintain both hot and cold shutdown conditions. Safe shutdown systems are dis- cussed in Section 7.4 of the SAR. Information Systems Important to Safety are those systems which provide informa- tion for the safe operation of the plant during normal operation, anticipated operational occurrences, and accidents. The information systems important to safety include those systems which provide information for manual initiation and control of safety systems, to indicate that plant safety functions are being accomplished, and to provide information from which appropriate actions can be Rev. 3 - February 1984 USNRC STANDARD REVIEW PLAN Standard review plans are prepared for the guidance of the Office of Nuclear Reactor Regulation staff responsible for the
