he effluents from the above sources. The ETSB 10 SPLB review will include the system piping and instrumentation diagrams (P&IDs), and the process flow diagrams showing methods of operation and factors that influence waste treatment, e.g., system interfaces and potential bypass routes. 2. Equipment and ventilation system design capacities, expected flows and radionuclide concentrations, expected decontamination factors for radionuclides, and available holdup time. The 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 system capability to meet anticipated demands imposed by major processing equipment downtime and waste volume surges due to anticipated operational occurrences. 3. The quality group classifications of piping and equipment, and the bases governing the design criteria chosen. Design and expected temperatures and pressures, and materials of construction of the components of the system. 4. Design provisions incorporated in the equipment and facility design to facilitate operation and maintenance in conformance with the guidelines of Regulatory Guide 1.143. (Ref. 8) 11 12 5. Special design features to reduce leakage of gaseous waste or discharge of radioactive material in gaseous effluents. Special design features, topical reports incorporated by reference, and data obtained from previous experience with similar systems which are submitted with the SAR. 6. Design features to preclude the possibility of an explosion if the potential for explosive mixtures exist. Review Interfaces13 1. The SPLB performs the following reviews as part of its primary review responsibility under the SRP sections indicated:14 Design provisions incorporated to sample and monitor radioactive materials in gaseous process and
