n testing of systems and components, to estab- lish the functional capability of the equipment. 4. CSB reviews the provisions made in the design of the systems and the pro- gram for periodic inservice inspection and operability testing of the systems or components. The inspections are reviewed with regard to the purpose of each inspection. The operability tests that will be conducted are reviewed with regard to what each test is intended to accomplish. Judgment and experience from previous reviews are used to determine the acceptability of the inspection and test program. 6.2.5-7 Rev. 2 - July 1981 For plants at the operating license stage of review, CSB reviews the pro- posed technical specifications for the systems used to control combustible gas concentrations in the containment to assure that the requirements of General Design Criteria 41, 42 and 43 are met. 5. CSB reviews the capability to monitor system performance and control active components to be sure that control can be exercised over a system and that a malfunctioning system train or component can be isolated. The instrumen- tation provided for this purpose should be redundant and should enable the operator to identify the malfunctioning system train or component. 6. CSB reviews the extent of sharing of system equipment between plants at multi-unit sites or between sites to assure that system redundancy requirements are satisfied and that adequate procedural provisions have been made to assure the availability of the shared equipment on a timely basis. The results of CSB analyses of combustible gas production and accumulation are used to confirm the time available following postulated loss-of-coolant accidents to transport the shared equipment to the plant and put it into operation. CSB reviews the containment penetrations needed for plants that utilize external recombiners to assure the single failure criteria outlined in Item II.E.4.1 of NUREG-0737 or NUREG-0718 are met. 7. CSB reviews analyses of the
