3 Background (cont.) Original purpose was to manage, analyze data, and disseminate information for the ISOE (Information System on Occupational Exposure) Databases Original purpose was to manage, analyze data, and disseminate information for the ISOE (Information System on Occupational Exposure) Databases The ISOE program was created by the OECD Nuclear Energy Agency in 1992 and subsequently co-sponsored by the IAEA for non-NEA Member countries The ISOE program was created by the OECD Nuclear Energy Agency in 1992 and subsequently co-sponsored by the IAEA for non-NEA Member countries ISOE is a data collection and communications network for nuclear electric utilities and national regulatory agencies. ISOE is a data collection and communications network for nuclear electric utilities and national regulatory agencies. The objective of the program (and that of NATC) is: The objective of the program (and that of NATC) is: to provide a worldwide dose reduction information exchange network to reduce occupational exposure at nuclear power plants

7 NATC Public Radiation Research Program Public Radiation Safety Research Program officially started in 1995 when the NRC asked the NATC to take over the task of collecting and tabulating US NPP effluent data (formerly BNL). Public Radiation Safety Research Program officially started in 1995 when the NRC asked the NATC to take over the task of collecting and tabulating US NPP effluent data (formerly BNL). The NATC has been designated as the lead scientific organization to collect, tabulate, analyze, and distribute the US effluent database The NATC has been designated as the lead scientific organization to collect, tabulate, analyze, and distribute the US effluent database This role began in 1998 starting with the 1994 effluent data. This role began in 1998 starting with the 1994 effluent data.

8 NATC Public Radiation Research Program Goals Developed by NATC staff with technical support from US NRC, US EPA and US DOE staff. Developed by NATC staff with technical support from US NRC, US EPA and US DOE staff. 1.Development of US gaseous and liquid effluent database for use by US NPP, US NRC, CEPN (France) and UNSCEAR (UN-Austria) 2. Expanded trend analysis and discussion in annual US effluent reports since 1994 to assist the US industry and regulatory bodies on benchmarking efforts 3. Establishment of a North American Effluent web site 4. Establishment of a North American Expert Group 5. Development of a standardized electronic data entry form for licensee use

9 Effluent Databases Effluent data has been collected from the NRC directly, utilities, and the NRC public reading room (ADAMS –post 1998) Effluent data has been collected from the NRC directly, utilities, and the NRC public reading room (ADAMS –post 1998) The data is entered into an EXCEL spreadsheet, and unit conversions are performed (both imperial and SI units) The data is entered into an EXCEL spreadsheet, and unit conversions are performed (both imperial and SI units) Data is broken up by unit and site totals Data is broken up by unit and site totals The data is then normalized by using the annual electrical energy generated (also kept as raw data) The data is then normalized by using the annual electrical energy generated (also kept as raw data) Current studies now include sister plant comparisons, dose evaluations (CED), and country comparisons Current studies now include sister plant comparisons, dose evaluations (CED), and country comparisons
