REVIEW RESPONSIBILITIES Primary - Effluent Treatment Systems Branch (ETSB) Secondary - Radiological Assessment Branch (RAB) I. AREAS OF REVIEW The primary review function is performed by ETSB. At the construction permit (CP) stage, ETSB reviews the information in the applicant's preliminary safety analysis report (PSAR) in tfie specific areas that follow. During the operating license (OL) stage of review, the ETSB review consists of confirming the design accepted at the CP stage and evaluating the adequacy of the applicant's technical specifications in these areas. The ETSB review includes: 1. The liquid radwaste treatment system design, design objectives, design criteria, methods of treatment, expected releases, and principal parameters used in calculating the releases of radioactive materials in liquid effluents including the system piping and instrumentation diagrams (P&IDs) and process flow diagrams showing methods of operation and factors that influence waste treatment, e.g., system interfaces and potential bypass routes. 2. Equipment design capacities, expected flow and radionuclide concentrations, expected decontamination factors for radionuclides, and available holdup time. 3. The 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. 4. The 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 due to anticipated operational occurrences. 5. The quality group classifications of piping, and equipment, and the bases governing the design.criteria chosen.
