4 ISOE Programme Created in 1992 by OECD/NEA as a forum for RP experts from utilities and regulatory authorities world-wide to share amongst participants dose reduction information & coordinate projects to improve optimisation of worker radiological protection at NPPs Promoted and sponsored by NEA and IAEA... the exchange and analysis of information on collective radiation doses to the personnel of nuclear installations and to the employees of contractors, as well as on dose-reduction techniques, is essential to implement effective dose-control programmes and to apply the ALARA principle... (ISOE Terms and Conditions, ) ISOE facilitates occupational exposure management at NPPs through the operation of a system for exchanging, storing, and analysing operational information and experience on optimising occupational radiological protection in response to user needs: World s largest occupational exposure database for commercial NPPs An information exchange programme for sharing dose reduction information and experience Four ISOE technical centres support local members (Asia, Europe, North America and IAEA)

5 Status of participation ISOE Terms and Conditions: NEA/CRPPH/ISOE(2012)1(showing latest status, reapproved in 2011) Official Participants 70 participating utilities from 29 countries Operating: 323 Shutdown: Regulatory authorities from 25 countries ISOE database Occupational exposure information from 401 operating units and 81 units in coldshutdown or some stage of decommissioning in 29 countries(covering about 91% of the world's operating commercial power reactors) Confirmation of acceptance of Terms and Conditions, on-going. Office of Nuclear Regulation (an agency of the HSE) new regulatory authority. The new RA of Japan (Nuclear Regulation Authority-NRA) has been invited to the ISOE Programme.

10 What is in the ISOEDATDatabase? ISOE 1: Dosimetricinformation from commercial NPPs in operation, shut down or in some stage of decommissioning, including: annual collective dose for normal operation maintenance/refuelling outage unplanned outage periods annual collective dose for certain tasks and worker categories ISOE 2:Plant-specific information relevant to dose reduction, such as materials, water chemistry, start-up/shutdown procedures, etc. ISOE 3:Radiation protection related information for specific operations, jobs, procedures, equipment or tasks (radiological lessons learned): effective dose reduction effective decontamination implementation of work management principles

11 Who Can Access the Database? ISOE Participants can access the DB on-line (ISOE website) and on CD-ROM (Microsoft ACCESS) Web version is routinely updated CD-ROM is distributed annually after all data received A set of pre-defined data queries facilitates trend analysis, benchmarking between plants, sister units, etc. Participating Utilities: Full access to global database (ISOE 1, 2, 3) Participating Authorities: Full access to ISOE 1 data from national licensees Limited access to ISOE 1 data from other countries General information, annual dose statistics, information about external and internal dose CD-Rom needed by 3 countries: Armenia, Russian Federation and by some German plants

12 Database Analyses and Benchmarking The extensive data in ISOEDAT provides a solid basis for analyses on issues in operational RP such as dose trends, doses related to certain jobs and tasks, identification of good performance, etc. Several ways to use the database: MADRAS analysis package: Main trends in occupational exposure Direct access to ISOE 1 questionnaires, including contact information and complementary data For more complex analyses: Direct access to DB, requests to the technical centres, RP forum,

13 Database Analyses and Benchmarking

14 MADRAS Data Analysis Package A set of pre-defined data queries to facilitate analysis of main trends in occupational exposure, benchmarking between plants, sister units, etc. Benchmarking at unit level Total annual collective dose Annual average collective dose per reactor Rolling average collective dose per reactor Total annual collective dose vs. number of operating reactors Total annual collective dose by reactor age Average annual collective dose per TWh Contribution of outside personnel and outages to total collective dose Dose rates AllautomateddosereportsareavailableinSvorrem

15 Using ISOEDATas a Benchmarking Tool Analyses at country or regional level Trends in Annual average collective dose per reactor / Annual total collective dose Between countries or regions: by country/region for a given reactor type, or all reactors, including 3-yr rolling average Within a country: Specific unit against another unit or by type of reactor Analyses at utility level Specific utility against other utilities Specific utility by reactor type Analyses at unit level Specific unit against another unit / sister group / reactor type Benchmarking at the job and task level

16 Bookmarks All parameters of the analysis are saved ( appears once you ve run the analysis and is available at the bottom of the list)

17 New MADRAS Analyses provided in 2012 Quartile Ranking analyses based on rolling average collective dose per reactor For a country For a country and a reactor type For a reactor type By number of loops (PWR) Plant Unit Ranking analyses based on rolling average collective dose per reactor For a country For a country and a reactor type For a reactor type By number of loops (PWR)

18 New MADRAS Analyses MADRAS Analysis module is improved every year with new developments based on user feedback and requests New analyses planned for 2013: A set of new queries to improve outage benchmarking Benchmarking analyses by reactor age This analysis compares the evolution of the total annual dose of one unit with that of other units from the same age or up to ±10 years. The selection of the compared units can be done by reactor type or by country.

19 Data Completeness Authorities have access to detailed information since January 2013 (only for Data completeness form)

20 Data Extraction Possibility to extractany type of data of the ISOE 1 Questionnaire in order to perform your own analyses

21 Pilot Project: Electronic Reporting to ISOE Electronic Reporting Module for US Utilities data entry and submission to ISOE program from US utilities use existing US utility systems to collate ISOE data into a central data file Goals of US Pilot Project Reduce manual entry and inefficiencies in current process Increase US utility participation in ISOE program by decreasing burden to submit data Increase use of database to highlight other ISOE products useful in the exchange of operational experience Effective collaboration between between NEA, CEPN, ORAU, PTI Systems, Duke Energy, and US NRC

22 Utility generates the electronic file from Sentinel. Utility views and validates the data prior to submittal. Next step: Implementation plan for ISOE Participants Utility submits the data file. NEA loads data into database as Unvalidated data. Utility and NATC validate data. Data available to all users.
