  1. U.S. Strategy with Respect to ISO Nuclear Energy Standards Dr. George Flanagan ISO Subcommittee SC-6 Chairman, Reactor Technology July 23, 2013

  2. Background on ISO nuclear technology standards

  3. ISO-TC-85 has 21 participating countries (voting) and 20 observing countries (non-voting)

  4. ISO-TC-85 has 21 participating countries (voting) and 20 observing countries (non voting) (cont’d)

  5. SC-6 has 22 participating countries (The Netherlands is not participating TC-85) and the U.S. national standards’ body is ANSI

  6. In addition to member states TC-85 has established formal liaison contacts • Institutional organizations: IAEA, UNSCEAR, WHO, ICRP, OECD/NEA, ICRU, EC, WANO, et.al ; • Professional organizations: WNA, PNC, ENISS, WANO, ISSPA, WNTI, et.al.; • Research organizations: ITER, GIF,et.al.; IAEA International Atomic Energy Agency ( ISO TC-85 chair and SC-6 chair -nonvoting member of NUSSC (Nuclear Safety Standards Committee) UNSCEAR: United Nations Scientific Committee on the Effects of Atomic Radiation WHO: World Health Organization ICRP: International Commission on Radiological Protection ICRU: International Commission on Radiation Unit WANO: World Association of Nuclear Operators WNA: World Nuclear Association PNC: Pacific Nuclear Council WANO: World Association of Nuclear Operators ISSPA: International source suppliers and producers association WNTI : World Nuclear Transport Institute ITER : International Thermonuclear Experimental Reactor GIF: Generation IV International Forum

  7. SC-2 (radiation protection) is the largest TC 85 subcommittee (12 WG)

  8. SC-2 is the largest TC 85 subcommittee(12 WG)

  9. SC-2 is the largest TC 85 subcommittee (12 WG)

  10. SC-5 (nuclear fuel cycle) has 5 WGs

  11. SC-6 (reactor technology) has 3 WGs

  12. SC-6 WG 1 (power reactor analysis and measurements) activities—Many of these are harmonization of existing ANS standards • Active projects • Technical specification guide for decay heat computation codes in nuclear reactors • Steady state neutronics methods for power reactor analysis • Reload startup physics tests for pressurized water reactors • Preliminary work items • Calculation of decay heat power in nuclear fuel in light-water reactors (LWRs) • Nuclear data sets for reactor design calculations • Nuclear data for the production of radioisotopes • Ballot • Neutron fluence in the pressure vessels of LWRs

  13. SC-6 WG 2 activities • Working Group 2 has been inactive for a number of years. • Dr. Lin-Wen Hue from MIT (has assumed the convener role for U.S.) • Dr. Patrick Raymond (CEA) co-convener • Examining ANSI / ANS Research Reactor Standards for harmonization • Many previously non-nuclear member states are considering building research reactors • Important that they have guidance for this activity

  14. WG 3 (New title: Power reactor, siting, design, operation, and decommissioning) • Active • Mobile equipment for emergency intervention on nuclear installations • Fire partitioning • Essential technical requirements for GEN IV nuclear reactors • New work item proposal • Estimating tornado, hurricane, and extreme straight line wind characteristics at nuclear facility sites • Criteria for assessing atmospheric effects on the ultimate heat sink • Preliminary work item • Criteria for investigations of nuclear facility sites for seismic hazard assessments • Probabilistic seismic hazards

  15. What should the U.S. strategy be regarding ISO nuclear energy standard?—Consider: • Many developing countries are using IAEA’s “standards” for development of their nuclear programs • IAEA’s “standards” are top level requirements (programs, infrastructure)—Reviewed by regulatory bodies represented on NUSSC • Need to address technical issues at a lower level (design/process) • IAEA looks to ISO to fulfill that role on an international basis • Global nuclear market requires international standards • Important to get it right • US, France, Great Britain, Sweden, Canada are active in harmonization of their standards into ISO standards (AREVA, CEA, Sellafield, EdF)

  16. What should the U.S. strategy be regarding ISO nuclear energy standard? • Ignore them? • Other members will produce them • USNRC and WANO are beginning to recognize IAEA and ISO activities - US market interest- NRC Chairwoman McFarland Remarks to NEI “Nuclear Energy Assembly” May 2012—“The new normal” • Influence direction of ISO standards (U.S. expertise exists for every TC-85 activity) • Propose nuclear standards for international harmonization (ASTM has done this for radiation protection— ANS beginning) • Participate on working groups and standards development bodies (experts)

  17. What should the U.S. strategy be regarding ISO nuclear energy standard? (cont’d) • Influence direction of ISO standards (U.S. expertise exists for every TC-85 activity) (cont’d) • Review of PWI, NWIP and draft standards (ballot time is short) • ANSI has one vote • Nuclear Technical Advisory Group (NTAG) administered by ASTM set up to reach consensus for U.S. vote by ANSI (U.S. has missed several votes recently—can determine if the standard is approved) • Each SC has a U.S. advisor responsible for NTAG input in their area (SC-6 P. Kadambi) • (ISO rule) Need to provide expert(s) if voting positively on a NWIP • Populate a list of experts to NTAG (current list is out of date)

  18. What should the U.S. strategy be regarding ISO nuclear energy standard? (cont’d) • Provide financial support to ISO nuclear standards especially staffing of SC and WG positions (U.S. loses the position if it does not have qualified active participation) • Travel to international TC-85 and SC meetings • Staff time for leadership roles • Staff time for experts • NUSSC participation by TC-85 and SC-6 provide opportunity for input and comments to IAEA standards/revisions by organizations outside the USNRC • Active NTAG could review and comment on these important standards
