piping break without offsite power. However, depending upon the type and location of the postulated pipe break, certain safety equipment may not be classified as "essential" for that particular event (e.g., emergency power system or high and low pressure core spray systems). On the other hand, some safety equipment will be "essential" for almost all cases (e.g., service water to ultimate heat sink). Table 3.6.1-1 is a list of those essential systems generally in the latter category. 5. 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 action items; however, to ensure these COL action items are addressed during a COL application, they should be added to the DC FSAR. For review of a COL application, the scope of the review is dependent on whether the COL applicant references a DC, an ESP or other NRC approvals (e.g., manufacturing license, site suitability report or topical report). For review of both DC and COL applications, SRP Section 14.3 should be followed for the review of ITAAC. The review of ITAAC cannot be completed until after the completion of this section. 3.6.1-10 Revision 3 - March 2007 TABLE 3.6.1-1 SYSTEMS USUALLY REQUIRED FOR SAFE SHUTDOWN PWR BWR Service Water System Service Water System Auxiliary Feedwater System Reactor Coolant Injection System Volume Control System Automatic Depressurization System Decay Heat Removal System Residual Heat Removal System Component Cooling Water System Component Cooling Water System (if provided) Table 3.6.1-2 is a listing of systems typically classified as either high or moderate energy systems
