pril 1996 3.11-4 (5) AEBThe Materials and Chemical Engineering Branch (EMCB) reviews 39 Section 6.5.2. B. The ASB, ICSB, PSB, and RSBSCSB, SRXB, HICB, EELB, and EMCB confirm that 40 the SAR identifies all equipment as identified in paragraph 1 of subsection Idescribed in the second paragraph of subsection I.41 C. The ASB and CSB confirmSCSB confirms the location of each item of equipment, both 42 inside and outside the containment. Inside the containment, the location must be specified, whether inside or outside of the missile shield for pressurized-water-reactor (PWR) plants, or whether inside or outside of the drywell for boiling-water-reactor 43 (BWR) plants. D. The ASB, CSB, ICSB, PSB, and RSBSCSB, SRXB, HICB, EELB, and EMCB confirm 44 the validity of the descriptions of theanticipated operational occurrences and normal, abnormal, accident, and postaccident environments provided in the SAR. They will 45 also confirm the acceptability of the values provided in the SAR for the length of time that equipment is required to operate in accident environments. E. With regard to the environments resulting from loss of environmental control systems (heat tracing, ventilation, heating, air conditioning), the ASBHICB will confirm the 46 47 description of these environments as provided in the SAR for those areas which contain equipment, including electrical control and instrumentation equipment and instrument sensing lines which rely on heat tracing for freeze protection.48 F. The QABQuality Assurance and Maintenance Branch (HQMB) reviews and determines 49 that the applicant's quality assurance (QA) program described in Chapter 17 of the SAR 50 satisfies the requirements of 10 CFR Part 50, Appendix B, Criteria III, XI, and XVII. G. The AEB reviewsEmergency Preparedness and Radiation Protection Branch (PERB) and the EMCB review the adequacy of the radiation and chemical conditions for 51 qualification for the abnormal, accident, and postaccident environments, as well as
