2. The organization responsible for electrical engineering reviews the overall compliance with 10 CFR 50.63 requirements, as part of its primary review responsibility for SRP Section 8.4, including the adequacy of the SBO analysis, the adequacy of reliability targets for onsite ac sources (diesel generators), the duration for which the plant will be able to withstand or cope with, and recover from, a SBO event. 3. The organization responsible for the review of reactor systems determines those system components requiring electric power as a function of time for each mode of reactor 8.2-4 Revision 5 - May 2010 operation and accident condition as part of its primary review responsibility for SRP Sections 4.6, 5.4.6, 5.4.7, 5.4.12, 6.3, and 9.3.5. 4. The organization responsible for the review of plant systems determines those system components requiring electric power as a function of time for each mode of reactor operation and accident condition as part of its primary review responsibility for SRP Sections 6.5.1, 6.7, 9.1.3, 9.1.4, 9.2.1, 9.2.2, 9.2.4, 9.2.5, 9.2.6, 9.3.1, 9.3.3, 9.4.1 through 9.4.5, 9.5.1, 10.4.5, 10.4.7, and 10.4.9. 5. The organization responsible for the review of plant systems also verifies, on request, the adequacy of those auxiliary systems required for the proper operation of the preferred power system. These include such systems as heating and ventilation systems for switchgear in the circuits from the preferred power sources to the onsite power distribution system buses and main generator auxiliary systems such as the cooling water system, hydrogen cooling system, turbine electro-hydraulic control system, and air supply system. 6. The organization responsible for the review of plant systems verifies, on request, the physical arrangements of components and structures of the preferred power system to ensure that the paths from the preferred power sources to the standby power distribution system buses will not experience simultaneous failure
