REVIEW RESPONSIBILITIES Primary - Equipment Qualification Branch (EQB) Secondary - None 1. AREAS OF REVIEW The information presented in Section 3.1 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 per- forming their design safety functions under all normal, abnormal, and accident environmental conditions. The review will be performed to assure conformance with the requirements of 10 CFR Part 50, Appendix A, General Design Criterion 4. The "normal, abnormal, accident and post accident environmental conditionsu are deemed to include all environmental conditions which may result from any normal or abnormal mode of plant operation, design basis events, post-design basis events, and containment tests. Mechanical and electrical equipment associated with systems described below must be designed to meet the requirements as described under the acceptance criteria of this SRP section. Mechanical and electrical equip- ment covered by this SRP section includes equipment associated with systems that are essential to emergency reactor shutdown, containment isolation, reactor core cooling, and containment and reactor heat removal, or otherwise are essential in preventing significant release of radioactive material to the environment. Also covered by this SRP section is equipment (1) that performs the above functions automatically, (2) that is used by the operators to perform these functions manually, and (3) whose failure can prevent the satisfactory accomplishment of one or more of the above safety functions. Seismic qualification is addressed in SRP Section 3.10. Section 3.11 of the SAR is reviewed to determine whether the required environmental capability of all equipment, i.e., the capability to perform design safety functions under normal, abnormal, accident, and postaccident environments, will be or has been adequately
