EQUIPMENT REVIEW RESPONSIBILITIES Primary - Organization responsible for the review of environmental qualification of electrical equipment Secondary - Organization responsible for the review of instrumentation and control systems Organization responsible for the review of environmental qualification of mechanical equipment I. AREAS OF REVIEW The information presented in Section 3.11 of the applicant's safety analysis report (SAR) should be sufficient to support the conclusion that all items of equipment that are important to safety (mechanical, electrical, and instrumentation and control (I&C), including digital I&C) are capable of performing their design safety functions under all normal environmental conditions, anticipated operational occurrences, and accident and post-accident environmental conditions. The "normal environmental conditions, anticipated operational occurrences, and accident and post-accident environmental conditions" include all environmental conditions that may result from any normal mode of plant operation, anticipated operational occurrences, design basis events (as defined in 10 CFR 50.49(b)(1)(ii)), post-design basis events, and containment tests. The review will be performed to assure conformance with the environmental design basis requirements of 10 CFR Part 50, Appendix A, General Design Criterion (GDC) 4 which states, in part, that "Structures, systems, and components important to safety shall be designed to accommodate the effects of and to be compatible with the environmental conditions associated with normal operation, maintenance, testing, and postulated accidents, including loss-of-coolant 3.11-2 Revision 3 - March 2007 accidents." The review will assure conformance with the applicable portions of other relevant regulations, including 10 CFR Part 50, Appendix A, General Design Criteria (GDCs) 1, 2, and 23; and 10 CFR Part 50, Appendix B, Quality Assurance Criteria III, XI, and XVII. The review also assures conformance to 10 CFR
