ated to shared systems and components important to safety being capable of performing required safety functions. 3. General Design Criterion 44, as related to: a. The capability to transfer heat loads from safety-related structures, systems, and components to the heat sink under both normal operating and accident conditions. b. Suitable component redundancy so that safety functions can be performed assuming a single active component failure coincident With loss of offsite power. c. The capability to isolate components, systems, or piping if required so that safety functions are not compromised. d. Acceptance is based upon meeting the guidance of Regulatory Guide 1.27, Positions C-2 and C-3 and Regulatory Guide 1.72, Positions C-1, C-4, C-5, C-6, and C-7, as well as Branch Technical Position ASB 9-2. 4. General Design Criterion 45, as related to the design provisions to permit inservice inspection of safety-related components and equipment. 5. General Design Criterion 46, as related to the design provisions to permit operation functional testing of safety-related systems or components. 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 9.2.5-3 Rev. 2 - July 1981 given in subsection II of this SRP section. For operating license (OL) reviews, the procedures are 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. Upon request from the primary revlewer, the coordinated review branches will provide input for the areas of review stated in subsection I of this SRP section. The primary reviewer obtains and uses such input as required to assure that this review procedure is complete. Availability of an adequate supply of water for the ultimate heat sink is a basic
