EQUIPMENT REVIEW RESPONSIBILITIES Primary - Equipment Qualification Branch (EQB)Plant Systems Branch (SPLB)1 Secondary - NoneInstrumentation and Controls Branch (HICB)2 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 (mechanical, electrical, includes instrumentation and control) are capable of performing their design safety functions under all normal, abnormal, and accident environmental conditions, anticipated operational occurrences, and accident and postaccident environmental conditions. The "normal, abnormal, 3 environmental conditions, anticipated operational occurrences, and accident and postaccident 4 environmental conditions" are deemed to include all environmental conditions which may result 5 from any normal or abnormal mode of plant operation, anticipated operational occurrences,6 design basis events, post-design basis events, and containment tests. The review will be performed to assure ensure conformance with the requirements of 10 CFR Part 50, Appendix A, 7 General Design Criterion 4Criteria 1, 2, 4, and 23; the requirements of 10 CFR Part 50, Appendix B, Quality Assurance Criteria III, XI, and XVII; and the requirements of 10 CFR 50.49. Section 50.49 of 10 CFR contains specific requirements regarding the 8 9 qualification of electrical equipment important to safety that is located in a harsh environment. Electrical equipment important to safety is described in 10 CFR 50.49(b). Harsh and mild environmental conditions are discussed in subsection II. 10 11 DRAFT Rev. 3 - April 1996 3.11-2 Mechanical and electrical equipment associated with systems described belowin this paragraph12 must be designed to meet the requirements as described under the acceptance criteria of this Standard Review Plan (SRP) section.
