sence of N-16 in assessing doses from external radiation from the turbine buildings of BWR plants. The specific areas of review include the following topics: 1. Equipment and ventilation system design capacities, expected flow rates or volumes, source terms and radionuclide concentrations, expected decontamination factors or removal efficiencies for radionuclides, and holdup or decay time in tanks and charcoal delay beds. 2. System design capacity relative to the design and expected input flow rates and volumes, and the period of time the system is required to be in service to process normal waste flow rates and volumes. 3. Availability of standby equipment, alternate processing routes, and interconnections between permanently installed systems and skid-mounted processing equipment in order to evaluate the overall ability of the system to meet anticipated demands imposed by major processing equipment downtime and waste volume surges caused by AOOs. 4. Assigned quality group classifications of structures, piping and equipment, and the bases governing the design criteria (safety classifications and applicable codes and standards) for natural phenomena and man-induced hazards using the guidance of Regulatory Guide (RG) 1.143, “Design Guidance for Radioactive Waste Management Systems, Structures, and Components Installed in Light-Water-Cooled Nuclear Power Plants,” for gaseous wastes produced during normal operation and AOOs. 5. Design provisions incorporated in the equipment and facility design to facilitate operation and maintenance using the guidance of RG 1.143 for gaseous wastes produced during normal operation and AOOs. 6. Quality assurance (QA) provisions for radioactive waste management systems, structures, and components in support of design criteria using the guidance of RG 1.143 for gaseous wastes produced during normal operation and AOOs. 7. Design features that would reduce the volumes of gaseous waste processed by the GWMS; reduce radioactivity levels
