II. REVIEW PROCEDURES The procedures set forth below are used during the construction permit (CP) application review to determine that the design criteria and bases and the pre- liminary design as set forth in the preliminary safety 'analysis report meet the acceptance criteria given in subsection II of this SRP section. For the review of operating license (OL) applications, the review procedures and acceptance criteria given in subsection II will be used to verify that the initial design criteria and bases have been appropriately implemented in the final design as set forth in the final safety analysis report. One of the main objectives in the review of a CWS is to determine its function with regard to safety. Some cooling systems are designed as safety-related systems in their entirety, others have only portions of the system that are safety-related, and others are classified as nonsafety-related because they do not perform any safety function. To determine the safety category of a CWS, the PSB will evaluate its necessity for achieving safe reactor shutdown condi- tions or for accident prevention or accident mitigation functions. The safety functions to be performed by these systems in all designs are essentially the same, however, the method used varies from plant to plant depending upon the individual designer. Upon request from the primary reviewer, the coordinating review branches will provide input for the areas of review stated in subsection I of this SRP 9.2.2-5 Rev. 3 - June 1986 section. The primary reviewer obtains and uses such input as required to ensure that this review procedure is complete. In view of the various designs provided, the procedures set forth below are for a typical CWS designed entirely as a safety-related system. Any variance of the review procedures to take account of a proposed unique design will be such as to ensure that the system meets the criteria of subsection II. The reviewer will select and emphasize material from this SRP
