is reviewed to verify its adequacy with respect to SBO considerations. The reviewer verifies that the reliability program includes provisions that conform with Position C.1.2 of RG 1.155 and Positions C.2.2 and C.2.3 of RG 1.9. The reviewer also verifies that the effectiveness of maintenance activities under the program are monitored in accordance with the Maintenance Rule (10 CFR 50.65) and RG 1.160, including the periodic monitoring of the condition and performance of emergency onsite ac power sources against licensee-established goals, periodic evaluation of performance and condition monitoring activities and associated goals and preventive maintenance activities, evaluation of operating experience, and incorporation of appropriate corrective actions when performance or condition of emergency onsite ac power sources do not meet established goals. 9. Fire Protection for Cable Systems In ensuring that the requirements of GDC 3 have been met, the organization responsible for plant systems will review the design of the fire stops and seals, including the materials, their characteristics with regard to flammability and fire retardancy, and their fire underwriters rating, in accordance with SRP Section 9.5.1. All cable and cable tray penetrations through walls and floors, as well as any other types of cable ways or conduits, should have fire stops installed. The reviewer will verify the design adequacy of cable derating and raceway fill to ensure compliance with accepted industry practices. 10. 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 DCD. The reviewer should also consider the appropriateness of identified COL action items. The reviewer may identify additional COL action items; however, to
