eactor coolant pressure boundary, to function as part of ECCS assum- ing a single active failure coincident with the loss of offsite power, and to meet ECCS technical specifications. G. General Design Criteria 60 and 61 as they relate to CVCS components hav- ing provisions for venting and draining through closed systems. Other specific criteria used to review the CVCS and BRS design follows. 1. The CVCS should include provisions for monitoring: a. temperature upstream of the demineralizer to assure that resin tem- perature limits are not exceeded, and b. filter demineralizer differential pressure to assure that pressure differential limits are not exceeded. 2. The CVCS should have provision for automatically diverting or isolating the CVCS flow to the demineralizer in the event the demineralizer influent temperature exceeds the resin temperature limit. 3. A program is implemented to leakage from the makeup and letdown lines in accordance with Item III.D.1.1 of NUREG-0737 for OL applications and III.D.1.1 of NUREG-0718 for CP applications. III. REVIEW PROCEDURES The procedures 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. For the review of operating license (OL) applications, 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. The procedures for OL applications include a determination that the content and intent of the technical'specifications prepared by the applicant are in agreement with the requirements for system testing, minimum performance, and surveillance developed as a-result of the staff's review. 9.3.4-4 Rev. 2 - July 1981 Upon request from the primary reviewer, the coordinated review branches will provide input for the areas of
