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 Organization responsible for the review of radiation dose and dose rates used to determine the radiation environment for the environmental qualification of mechanical and electrical equipment I. AREAS OF REVIEW The information presented in Section 3.11 of the Final Safety Analysis Report (FSAR) should be sufficient to support the conclusion that all items of equipment that are important to safety (mechanical, electrical, and instrumentation and 3.11 -2 Draft Revision 4 – December 2017 control (I&C) equipment) are capable of performing their design safety functions under all normal environmental conditions, anticipated operational occurrences, and accident and post-accident environmental conditions. It includes 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. This Standard Review Plan (SRP) section also covers instrumentation that is needed to assess plant and environs conditions during and after an accident, as described in Regulatory Guide (RG) 1.97, “Criteria for Accident Monitoring Instrumentation for Nuclear Power Plants.” The U.S. Nuclear Regulatory Commission (NRC) regulations in Appendix A, “General Design Criteria for Nuclear Power Plants,” to Title 10 of the Code of Federal Regulations (10 CFR) Part 50, “Domestic Licensing of Production and Utilization Facilities,” require that structures, systems, and components (SSCs) important to safety be designed, fabricated, erected, and tested to quality standards commensurate with the importance of the
