REVIEW RESPONSIBILITIES Primary - Effluent Treatment Plant Systems Branch (ETSB) (SPLB)2 Secondary - Radiological Assessment Branch (RAB) Emergency Preparedness and Radiation Protection Branch (PERB)3 I. AREAS OF REVIEW At the construction permit (CP) or standard design certification stage of review, ETSB SPLB 4 5 reviews the information in the applicant's safety analysis report (SAR) in the specific areas that follow. At the operating license (OL) or combined license (COL) stage of review, ETSB SPLB 6 review consists of confirming the design accepted at the CP or standard design certification7 stage and evaluating the adequacy of the applicant's technical specifications in these areas. The ETSB SPLB review includes: 1. The gaseous waste management (treatment and ventilation) systems design, design 8 objectives, design criteria, methods of treatment, expected releases, and principal parameters used in calculating the releases of radioactive materials (noble gases, radioiodine, tritium, carbon-14, and particulates) in gaseous effluents. The gaseous 9 waste management system involves the gaseous radwaste system (GRS), which deals with the management of radioactive gases collected in offgas system (this system contains charcoal delay beds) or waste gas storage and decay tanks. In addition, it involves the management of condenser air removal system, steam generator blowdown flash tank (if applicable), and containment purge exhausts for PWRs; gland seal exhaust, and mechanical vacuum pump operation exhaust for BWRs; and building ventilation system exhausts for both PWRs and BWRs. The management for gaseous effluents to DRAFT Rev. 3 - April 1996 11.3-2 environment from the above sources may, in turn, involve treatment systems to reduce releases of radioactive material in the 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
