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

2 NESCC Presentation – Background on ISO nuclear technology standards

3 NESCC Presentation –

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

5 NESCC Presentation – ISO-TC-85 has 21 participating countries (voting) and 20 observing countries (non voting) (cont’d)

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

7 NESCC Presentation – 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

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

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

10 NESCC Presentation – SC-2 is the largest TC 85 subcommittee (12 WG)

11 NESCC Presentation – SC-5 (nuclear fuel cycle) has 5 WGs

12 NESCC Presentation – SC-6 (reactor technology) has 3 WGs

13 NESCC Presentation – 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

14 NESCC Presentation – 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

15 NESCC Presentation – 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

16 NESCC Presentation – 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)

17 NESCC Presentation – 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)

18 NESCC Presentation – 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) What should the U.S. strategy be regarding ISO nuclear energy standard? (cont’d)

19 NESCC Presentation – 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
