safety under NRC regulations. The review of the LWMS includes the design, design objectives, design criteria, methods of treatment, system interfaces, bypass routes to nonradioactive systems, expected releases, methods used to terminate or divert effluent releases, and calculation methods and principal parameters used in deriving effluent source terms and releases of radioactive materials in liquid effluents, including system piping and instrumentation diagrams (P&IDs) and process flow diagrams showing methods of operation that influence waste treatment. The specific areas of review include the following topics: 1. Equipment 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. 2. System design capacity, relative to the design and expected input flow rates and volume inventories, 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 subsystems and skid-mounted processing equipment in 11.2-3 Draft Revision 5 – August 2014 order to evaluate the overall system capability to meet anticipated demands imposed by major processing equipment downtime and waste volume surges resulting from AOOs. 4. Quality group classifications of structures, piping, and equipment and the bases governing design criteria (safety classifications and applicable codes and standards for natural phenomena and man-induced hazards) assigned using the guidelines 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 liquids and liquid wastes produced during normal operation and AOOs. 5. Quality assurance (QA) provisions for radioactive waste management
