e operational flexibility designed into the system (i.e., cross-connections between subsystems, redundant or reserve processing equipment, and reserve storage capacity). Based on the usage factors and operational flexibilities, an evaluation of the overall system capability to process wastes as related to item A, B, or C, above, is performed by comparing design flows with the potential process routes and equipment capacities. It will be assumed that the primary means for processing liquid waste is unavailable for 2 consecutive days per week for maintenance. If 2 days of holdup capacity or a primary water processing source is not available for the process stream, it will be assumed that the waste stream is processed by an alternate method or discharged to the environment, consistent with an effluent source term developed using the guidelines of NUREG-0016 or NUREG-0017 and Regulatory Guide 1.112. 3. The LWMS is reviewed to ensure that the design includes provisions to prevent and collect leakage resulting from overflows and spillage from indoor and outdoor storage tanks containing liquids and liquid wastes produced during normal operation and anticipated operational occurrences, and is in conformance with the guidelines of Regulatory Guide 1.143 and the requirements of 10 CFR 20.1406. The review considers information describing design features that will minimize, to the extent practicable, contamination of the facility and environment; facilitate eventual decommissioning; and minimize, to the extent practicable, the generation of radioactive waste in accordance with the guidance of Regulatory Guide 1.143, for liquids and liquid wastes produced during normal operation and anticipated operational occurrences, and the requirements of 10 CFR 20.1406. In addition, the review may also consider the information contained in the DC application, an update in the SAR, or the COL application, to the extent not addressed in a referenced certified design.
