range of 10-4 to 10-5 per demand based on an analysis using methods and data presented in NUREG-0611 and NUREG-0635. Compensating factors such as other methods of accomplishing the safety functions of the AFWS or other reliable methods for cooling the reactor core during abnormal conditions may be considered to justify a larger unavailability of the AFWS. 6. General Design Criterion 45, as related to design provisions made to permit periodic inservice inspection of system components and equipment. 7. General Design Criterion 46, as related to design provisions made to. permit appropriate functional testing of the system and components to assure structural integrity and leak-tightness, operability and perform- ance of active components, and capability of the integrated system to function as intended during normal, shutdown, and accident conditions. In meeting this criteria the technical specifications should specify that the monthly AFWS pump test shall be performed on a staggered test basis to reduce the likelihood of leaving more than one pump in a test mode following the tests. 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 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 also include a determina- tion 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. Upon request from the primary reviewer, the coordinating review branches will provide input for the
