res below are used during the construction permit (CP) review to determine that the design criteria and bases and the preliminary design as set forth in the preliminary safety analysis report meet the acceptance criteria given in subsection II of this SRP section. For the operating license (OL) review, the procedures are utilized 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. Upon request from the primary reviewer, the coordinating review branches will provide input for the areas of review stated in subsection III of this SRP section. The primary reviewer obtains 20 and uses such input as required to assure that the review procedures are complete. The reviewer will select and emphasize material from the procedures described below, as may be appropriate for a particular case. 1. The reviewer verifies that identified leakage will be collected in tanks or sumps where its rate of accumulation will be monitored to obtain an identified leak rate. The reviewer should establish that the identified leakage is not only collected and monitored, but also done in such a fashion as to prevent identified leakages from masking unidentified 21 leaks. 2. The reviewer verifies that the provisions for collecting, detecting and monitoring unidentified leakage are separate from identified leakage. The floor drainage system is reviewed to assure that leakage will flow readily to the sump or tank where it is collected without getting held up in any "reservoirs." The containment air coolers are reviewed to assure that leakage from "hot" systems which flashes into water vapor is readily condensed and that the condensate flows directly to the sump. 3. The reviewer determines that all potential intersystem leakage paths have been identified by the applicant. The reviewer determines that the instrumentation used in each path is appropriate and adequate to provide positive indication
