or accident conditions. 3. General Design Criterion 5, as related to the capability of shared systems and components important to safety being capable of performing required safety functions. 9.2.1-5 DRAFT Rev. 5 - April 1996 4. General Design Criterion 44, as related to transferring heat from structures systems and components important to safety, to an ultimate heat sink. Acceptance is based on the following: a. The capability to transfer heat loads from safety-related structures, systems, and components to a heat sink under both normal operating and accident conditions. b. Component redundancy so that the safety function can be performed assuming a single active component failure coincident with the loss of offsite power. c. The capability to isolate components, subsystems, or piping if required so that the system safety function will not be compromised. d. Meeting task action plan item II.K.1.22 of NUREG-0737 (Reference 9) for 33 boiling water reactors regarding automatic and manual actions necessary when the main feedwater system is not operable. For applicants subject to 10 CFR 50.34(f) and 10 CFR 52.47(a)(1)(ii) this acceptance criterion is equivalent to the requirement of 10 CFR 50.34(f)(2)(xxi) for boiling water reactors regarding the design of auxiliary heat removal systems such that necessary automatic and manual actions can be taken to ensure proper functioning when the main feedwater system is not operable.34 e. Meeting task action plan item II.K.1.22 of NUREG-0718 for B&W plants regarding automatic and manual actions for proper functioning of the auxiliary heat removal systems when the main feedwater system is not operable.35 5. General Design Criterion 45, as related to design provisions to permit inservice inspection of safety-related components and equipment. 6. General Design Criterion 46, as related to design provisions to permit operational functional testing of safety-related systems and components. Technical Rationale The technical rationale
