to system design the recommendation of Task Action Plan item [identify item number and how implemented] which we have reviewed and found acceptable. Our review of the ESFAS and ESF control systems has examined the dependence of these systems on the availability of essential auxiliary supporting (EAS) systems. Based on our review and coordination with those having primary review responsibility of the EAS systems, we conclude that the design of the ESFAS and ESF control systems are compatible with the functional performance requirements of EAS systems. Therefore, we find the interfaces between the design of ESFAS and EWF control systems and the design of EAS systems to be acceptable. The conclusions noted above for the ESFAS and ESF control systems are applicable to all portions of the systems except for the following for which acceptance is based upon prior Commission review and approval as noted. [List applicable system or topics and identify references] 7.3-8' Rev. 2 - July 1981 V. IMPLEMENTATION The following is intended to provide guidance to applicants and licensees regarding.-the NRC staff's plans for using this SRP section. Except in those cases in which the applicant proposes an alternative method for complying with specified portions regulations, the method described herein will be used by evaluation of conformance with Commission regulations. Implementation schedules for conformance to parts of the herein are contained in the referenced regulatory guides acceptable of the Commission's the staff in its method discussed and NUREGs. VI.
