REVIEW RESPONSIBILITIES Primary - Organization responsible for review of effectiveness of radwaste systems. Secondary - Organization responsible for review of radwaste system design and performance. I. AREAS OF REVIEW The liquid waste management system (LWMS) is designed to ensure that liquids and liquid wastes produced during normal operation, including anticipated operational occurrences, are handled, processed, stored, and released or routed to their final destination in accordance with the relevant regulations of the U.S. Nuclear Regulatory Commission (NRC). Review of the LWMS includes the design features that are necessary for collecting, handling, processing, releasing, and disposing of liquid effluents. This review encompasses, but is not limited to, piping, pumps, valves, filters, demineralizers, mobile equipment connected to permanently installed systems, and any additional equipment that may be necessary to process and treat liquid wastes and route them to the point of discharge from the system. The review of the LWMS includes the design, design objectives, design criteria, methods of treatment, expected releases, and calculation methods and principal parameters used in calculating 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 and factors that influence waste treatment, e.g., system interfaces and potential bypass routes to non-radioactive systems. The specific areas of review are as follows: 1. Equipment design capacities, expected flow, source terms and radionuclide concentrations, expected decontamination factors or removal efficiencies for radionuclides, and holdup or decay time. 11.2-2 Revision 3 - March 2007 2. System design capacity relative to the design and expected input flows and the period of time the system is required to be in service to process normal waste flows. 3. Availability of standby
