ANS RESPONSE TO FUKUSHIMA LESSONS LEARNED

1. Presented to: NESCC November 29, 2012 Washington D.C. ANS RESPONSE TO FUKUSHIMA LESSONS LEARNED Donald J. Spellman, Chair ANS Standards Board American Nuclear Society

2. Standards Process for Tier 3 Issues • Experience from PRA standards shows that achievement of consensus can be arduous and time-consuming when dealing with technology under development. • It can be done. • It saves NRC resources. • PINS process analogous to ANPR relative to some Tier 3 issues. • Standards process allows TUPA (Trial Use and Pilot Application). • Standards process can be performance-based to deal with incomplete Fukushima or other information. • Focus efforts where policy clarity obtains. AMERICAN NUCLEAR SOCIETY

3. SECY-2012-0095 on Tier 3 Issues • Characterization of Tier 3 issues • require further staff study to support a regulatory action, • shorter-term action that needs to be completed to inform the long-term action, and • availability of critical skill sets. • Eleven Issues identified with program plans and staff assessments. Some not related to NTTF recommendations. • Significant research needs identified in addition to Fukushima-related information. • Policy issues clearly identified. • Generally represents more information than is typically available at the start of standards projects. AMERICAN NUCLEAR SOCIETY

4. Potential Standards Approaches • Work with NRC staff to make maximum use of program plans for each Tier 3 issue. • Work with NEI and other SDOs to constitute one or more working groups. • Negotiate balloting rules to fulfill balance-of-interest and due-process considerations. • Create project plans to be consistent with research studies or information gathering. • Address critical skills issue by exploiting broad volunteer base. • Frame consensus issue in performance-based manner to enable experts to use qualitative and quantitative information to the maximum extent possible. • Ensure that important boundary conditions are captured in “shall” statements.
