Content:
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 equipment, alternate processing routes, and interconnections between subsystems in order to evaluate the overall system capability to meet anticipated demands imposed by major processing equipment downtime and waste volume surges resulting from anticipated operational occurrences. 4. Quality group classifications of piping and equipment and the bases governing the design criteria chosen in accordance with the guidelines of Regulatory Guide 1.143 for liquids and liquid wastes produced during normal operation and anticipated operational occurrences. 5. Provisions to prevent, control, and collect radioactive materials in liquids from tank overflows from all plant systems and the potential for tanks located outside of the reactor containment to result in uncontrolled and unmonitored releases, and design features applied to mitigate the effects of a postulated tank failure, e.g., steel liners, sumps, drains, or walls in areas housing tanks and components, dikes for outdoor tanks, and overflow provisions. 6. Design and expected temperatures and pressures and materials of construction of the components of the LWMS. 7. Design provisions to preclude placing the components and structures of the system under adverse vacuum conditions. 8. Provisions incorporated in the equipment and facility design to reduce leakage and facilitate operation and maintenance in accordance with the guidelines of Regulatory Guide 1.143 for liquids and liquid wastes produced during normal operation and anticipated operational occurrences. 9. Design features that would reduce volumes of liquid wastes to the LWMS; reduce radioactivity levels and discharges of radioactive materials in liquid effluents; minimize, to the extent practicable, contamination of the facility and environment; facilitate eventual
