provided to maintain a controlled environment for safety-related instrumentation and electric equipment. In particular, the organization responsible for the review of plant systems determines that the piping, ducting, and dampering for these heating and ventilation systems are adequate. 2. The organization responsible for the review of plant systems examines the physical arrangement of components and structures for Class 1E systems and their supporting auxiliary systems to determine that single events and accidents will not disable redundant features as part of its primary review responsibility for SRP Sections 3.4.1, 3.5.1.1, 3.5.2, and 3.6.1. 3. The organization responsible for the review of plant systems determines those system components needing electric power as a function of time for each mode of reactor 8.3.1-6 Revision 4 - May 2010 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, 10.4.5, 10.4.7, and 10.4.9. 4. The organization responsible for the review of plant systems examines fire detection and fire protection systems protecting the ac power system and its auxiliary supporting systems to ensure that the adverse effects of fire are minimized as part of its primary review responsibility for SRP Section 9.5.1. This review includes examining the adequacy of protection provided for redundant safe shutdown circuits to determine that a single design basis fire will not disable both redundant circuits. 5. The organization responsible for the review of materials and chemical engineering determines those system components needing 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 5.4.8, 9.2.3, 9.3.2, and 9.3.4. 6. The organization responsible for the review of containment systems and severe accidents evaluates the adequacy of those
