  1. Technical Meeting onEvaluation Methodology for Nuclear Power Infrastructure Development10-12 December, 2008Nuclear Safety in Infrastructure Building J. Bastos Policy and Programme Coordination Section Department of Nuclear Safety and Security

  2. Contents • What is nuclear safety infrastructure and why is it important • What are the main elements of the nuclear safety infrastructure • Safety Standards and Safety Services December 2008

  3. What is nuclear safety infrastructure and why is it important December 2008

  4. Robust and safe design Competent staff in all organizations NPP operation Nuclear Safety Inventory of radioactive materials Legal and regulatory framework Embedded Safety Culture Appropriate funding Safe management of radioactive waste Radiation hazards to workers, public and the environment Proliferation Issues Protection against ionizing radiations Others … Nuclear Security Safeguards Specificity of Nuclear Power December 2008

  5. Infrastructure for nuclear power Nuclear Safety Infrastructure Definitions Nuclear Safety Infrastructure: • Is the set of provisions established in a Member State to provide a sound foundation for ensuring a sustainable high level of nuclear safety December 2008

  6. Main Actors • State • Establish an appropriate legal framework • Establish, empower and ensure financial support to the Regulatory Body • Adhere to the Global Nuclear Safety Regime • Ensure that all stakeholders have access to reliable information • Regulatory Body • Establish safety principles and requirements • Set-up or adopt regulations and guides • Establish an authorization process • Review and assess safety documentation • Inspect and enforce • Inform the public in a transparent manner December 2008

  7. Main Actors • Operating Organization • Prime responsibility for safety: • Establish and maintain the necessary competences; • Provide adequate training and information; • Establish procedures and arrangements to maintain safety under all conditions; • Verify appropriate design and the adequate quality of facilities and activities and of their associated equipment; • Ensure the safe control of all radioactive material that is used, produced, stored or transported; • Ensure the safe control of all radioactive waste that is generated. December 2008

  8. What are the elements of the nuclear safety infrastructure December 2008

  9. Institutional elements • Organizational Elements • Technical Safety Elements Elements of the Nuclear Safety Infrastructure Robust and safe design Competent staff in all organizations Nuclear Safety Legal and regulatory framework Embedded Safety Culture Appropriate funding Safe management of radioactive waste Protection against ionizing radiations Others … Safety Guide under preparation (DS424) December 2008

  10. Institutional Elements • National legal and regulatory framework • Human Resources development • Transparent communication on benefits and risks of nuclear power • National technical infrastructure • Safety Research • Financing and funding mechanisms • International commitments and cooperation • Leadership and Management for Safety December 2008

  11. Organizational Elements • Regulatory Body • Technical Support organizations • Operating Organization • Industrial Organizations • Provision of Technical Services December 2008

  12. Technical Safety Elements • Radioactive Waste and Spent Fuel Safety and decommissioning • Emergency Preparedness and Response • Physical protection and security • Site evaluation • Design safety • Assessment and Verification • Radiation protection • Transportation of radioactive materials December 2008

  13. Safety Documents using the Phasing Approach December 2008

  14. Relation Between DS424 - Milestones • DS424 uses the concept of Phases as in the Milestones • DS424 groups the actions in 3 main groups • DS424 limits its scope to safety • DS424 identifies (at present) 21 actions against 19 issues in the Milestones • Relation 1 to 1 for many of the actions/issues December 2008

  15. Safety Standards and Safety Services December 2008

  16. Safety Fundamentals Safety Requirements Safety Guides IAEA Safety Standards Safety Standards are: • Non binding on Member States but may be adopted by them • Binding on States in relation to operations assisted by the IAEA or States wishing to enter into project agreements with IAEA • Represent a consensus in MS • Reflect best practices December 2008

  17. Safety Fundamentals Thematic standards Facilities specific standards Legal and governmental infrastructure Nuclear power plants: design Nuclear power plants: operation Emergency preparedness and response Management systems Research reactors Fuel cycle facilities Assessment and verification Site evaluation Radiation related facilities and activities Radiation protection Waste treatment and disposal facilities Radioactive waste management Decommissioning Remediation of contaminated areas Transport of radioactive material General safety (cross-cutting themes) Safety of nuclear facilities Radiation protection and safety of radiation sources http://www-ns.iaea.org/standards/ Safe management of radioactive waste Safe transport of radioactive material IAEA Safety Standards December 2008

  18. Safety Services The IAEA provide safety review services under MSs request in the following areas: • Operational Safety for NPPs- OSART • Research Reactor Safety - INSARR • Legal and governmental infrastructure – IRRS • Siting Evaluation - ENSARS • Design Evaluation – ENSARS • Fuel Cycle Facilities During Operation – SEDO • Safety Culture – SCART • PSA – IPSART December 2008

  19. Milestone 1 Milestone 2 Milestone 3 Phase 1 Phase 2 Phase 3 Phase 4 DS424 is the first SS covering Phases 1 and 2 Coverage of the Safety Standards and Services The current IAEA SS may be adopted as part of the Regulatory Framework but they not distinguish Phases IRRS with limited scope Most IAEA safety services were tailored for Phases 3 and 4: OSART, IRRS… Some IAEA safety services are suited for the earlier phases: Site Evaluation, Design reviews, PSA December 2008
