REVIEW RESPONSIBILITIES Primary - Effluent Treatment Systems Branch (ETSB)Plant Systems Branch (SPLB)1 Secondary - NoneEmergency Preparedness and Radiation Protection Branch (PERB)2 I. AREAS OF REVIEW This review addresses engineered safety feature (ESF) atmosphere cleanup systems designed for fission product removal in postaccident environments. These systems generally include primary systems, such as in-containment recirculation, and secondary systems, such as standby gas treatment systems and emergency or postaccident air-cleaning systems for the fuel-handling building, control room, shield building, and areas containing ESF components.3 At the construction permit (CP) stage of review, ETSBSPLB reviews the information in the 4 applicant's safety analysis report (SAR) in the areas listed below. At the operating license (OL) stage, the ETSBSPLB review consists of confirming the design accepted at the CP stage and 5 evaluating the adequacy of the applicant's technical specifications in these areas. For each ESF atmosphere cleanup system, the specific ETSBSPLB review areas are as follows: 6 7 1. The engineered safety feature (ESF) atmosphere cleanup systems designed for fission product removal in post-accident environments. These generally include primary systems, such as in-containment recirculation, and secondary systems, such as standby gas treatment systems and emergency or post accident air cleaning systems for the fuel handling building, control room, shield building and areas containing engineered safety feature components.8 DRAFT Rev. 3 - April 1996 6.5.1-2 21. The system design, design objectives, and design criteria. The ETSBSPLB reviews the 9 methods of operation and the factors that could influence the filtration capabilities of the system, e.g., system interfaces and potential bypass routes. The components included in each atmosphericatmosphere cleanup system and the seismic design category of each 10 system are reviewed. Redundancy of the atmosphere
