Published standard review plans will be revised periodically. as appropriate, to accommodate comments and to reflect new informa- tion and experience. Comments and suggestions for improvement will be considered and should be sent to the U.S. Nuclear Regulatory Commission, Office of Nuclear Reactor Regulation. Washington, D.C. 251;5 4. Technical Specifications The proposed technical specifications are reviewed to assure that they are adequate in regard to limiting conditions of operation and periodic surveillance testing. The ability of the ECCS to mitigate the consequences of a spectrum of loss-of-coolant accidents is reviewed by RSB under SRP Section 15.6.5. In addition the RSB will coordinate with other branches evaluations that interface with the overall ECCS review as follows: Auxiliary Systems Branch (ASB), as part of its primary review responsibility for SRP Sections 9.2.1, 9.2.2, 9.2.5, and 9.2.6, reviews those auxiliary systems essential for ECCS operation (service water system, component cooling system, ultimate heat sink, and condensate storage facility) and assesses the capability of these systems to perform all functions required by the ECCS. The ASB will supply, on request, evaluations of portions of the power conversion systems (e.g., steam supply lines, steam generators, feedwater systems) which interface with the reactor coolant system in such a way as to influence the course of a loss-of-coolant accident (LOCA) for a particular plant. The ASB also reviews the effects of pipe breaks outside containment on ECCS. This review includes the effect of pipe whip, jet impingement forces, and environmental conditions created as part of its primary review responsibility for SRP Section 3.6.1. Instrumenta- tion and Control Systems Branch (ICSB), as part of its primary review responsibility for SRP Section 7.3, reviews the adequacy of ECCS-associated controls and instrumentation with regard to the features of automatic actuation, remote sensing and indication,
