influence waste treatment (e.g., system interfaces and potential bypass routes to nonradioactive systems). 11.3-2 Revision 3 - March 2007 The specific areas of review are as follows: 1. Equipment and ventilation system design capacities, expected flows, 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 flows, the period of time the system is required to be in service to process normal waste flows, availability of standby equipment, alternate processing routes, and interconnections between subsystems. This information is used to evaluate the overall ability of the system to meet anticipated demands imposed by major processing equipment downtime and waste volume surges cause by anticipated operational occurrences. 3. Quality group classifications of piping and equipment, the bases governing the chosen design criteria, design and expected temperatures and pressures, and materials used to construct the system components. 4. Design provisions incorporated in the equipment and facility design to facilitate operation and maintenance in conformance with Regulatory Guide 1.143 for gaseous wastes produced during normal operation and anticipated operational occurrences. 5. Design features that would reduce the volumes of gaseous waste to the GWMS; reduce radioactivity levels and discharges of radioactive materials in gaseous effluents; 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. 6. Design features to reduce leakage of gaseous waste or discharges of radioactive materials in gaseous effluents to avoid uncontrolled and unmonitored releases to the environment, special design features, topical reports incorporated by reference, and data obtained from previous
