uel oil tank has been filled, to exclude sources of ignition like open flames or hot surfaces and whether protective measures like compartmentation of redundant elements minimize the potential for and consequences of fires and explosions. 8. The reviewer verifies whether the system function will be maintained as required in any failure of nonseismic Category I systems or structures near the system. Reference to SAR sections describing site features and general arrangement and layout drawings is necessary in this verification. Plant arrangement features and the protections obtained by location and the design of the system and structures are considered in determining the ability of the system to maintain functions in such failures. 9.5.4-9 Revision 3 - March 2007 9. The EDEFSS is reviewed for protection from the effects of breaks in high and moderate energy lines. Layout drawings are reviewed for whether high or moderate energy piping systems are located close to the fuel oil system and for protection from the effects of failure. Provisions for such protection are in SAR Section 3.6 and procedures for reviewing this information are in the corresponding SRP sections. 10. The SAR descriptive information, related system drawings, and results of failure modes and effects analyses are reviewed to verify whether minimum system requirements will be met following DBAs, assuming a concurrent single active component failure. For each case the design is acceptable if minimum system requirements are met. 11. For review of a DC application, the reviewer should follow the above procedures to verify that the design, including requirements and restrictions (e.g., interface requirements and site parameters), set forth in the final safety analysis report (FSAR) meets the acceptance criteria. DCs have referred to the FSAR as the design control document (DCD). The reviewer should also consider the appropriateness of identified COL action items. The reviewer may identify additional COL
