ludes all electric and electromechanical equip- ment involved in detecting a plant condition requiring operation of an ESF or EAS system and in initiating the operation of the ESF or EAS system. 7.3-2 Rev. 2 - July 1981 2. The descriptive information pertaining to the instrumentation and control systems for the control of ESF systems that are essential to the operation of the ESF systems. 3. The acceptance criteria, guidelines, and design bases used for the design of the ESFAS and the ESF control systems (CP). 4. The applicant's analysis of the conformance to the acceptance criteria, guidelines, and design bases for tne ESFAS and for the ESF control systems (OL). In addition the ICSB will coordinate with branches that interface with the overall review of ESF systems for the following aspects of ESFAS: (1) The adequacy of the monitored variables, i.e., the suitability of parameters, such as pressure, for initiating operation of a given ESF or EAS system. (2) The acceptability of the proposed trip setpoints, time delays, accuracy requirements, and actuated equipment response consistent with the safety analysis included in Chapter 15 of the SAR. The coordinated reviews include the following: The Power Systems Branch (PS8) evaluates the adequacy of physical separation criteria for cabling and electrical power equipment and determines that control and motive power supplied to redundant systems is from appropriate redundant sources and the adequacy of the instrumentation and controls associated with the proper functioning of the onsite and offsite power systems as part of its primary review responsibility for SRP Sections 8.2, 8.3.1, and 8.3.2. The Auxiliary Systems Branch (ASB) evaluates the adequacy of the EAS systems to assure that the instrumentation and control aspects of the EAS systems satisfy the acceptance criteria applicable to these systems as part of its primary review responsibility for SRP Chapter 9 and 10. This review confirm that the design of the EAS
