Content:
PWRs and BWRs, the LWMS is designed to ensure that liquids and liquid wastes produced during normal operation, including anticipated operational occurrences (AOOs), are handled, processed, stored, and released or routed to their final destination in accordance with the relevant NRC regulations. The review of the LWMS includes design features that are necessary for collecting, handling, processing, treating, releasing, storing, and disposing of liquid effluents. This review encompasses, but is not limited to tanks, 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 LWMS has been categorized as nonsafety-related and nonrisk-significant. Failure of subsystems must not compromise any safety-related system or component, nor may it prevent the safe shutdown of the plant. However, the failure of specific subsystems or components may have some impacts on the means to control and monitor liquid effluent releases and on compliance with Title 10 of the Code of Federal Regulations (10 CFR) Part 20, “Standards for Protection Against Radiation,” regulations in controlling liquid effluent releases to unrestricted areas and doses to members of the public. The LWMS is relied on to treat and control releases of radioactive materials in liquid effluents to the environment; therefore, it has a direct impact in complying with 10 CFR Part 20 regulations. As such, the review of the LWMS must be sufficient to assure that the staff has reasonable assurance that public health and safety is adequately protected. The applicant's FSAR must provide sufficient information to confirm that any failure of essential subsystems will not compromise public health and safety under NRC regulations. The review of the LWMS includes the design, design objectives, design criteria, methods of treatment,
