  1. American Nuclear SocietyNuclear Criticality Safety Division Presentation to the ANS Board of Directors Steve Bowman Nov. 16, 2005 Washington, D.C.

  2. NCSD Mission • NCSD focuses on the prevention of criticality accidents in areas outside of nuclear reactors • Promote the safe handling of fissionable materials outside reactors • Promote the arts and sciences of nuclear criticality safety • Provide exchange of technical information among NCS professionals through • development of standards • evolution of training methods and materials • presentation of technical data and procedures • creation of specialty publications

  3. NCSD Executive Committee • Chair: Steve Bowman, Oak Ridge National Lab. • Vice Chair: Kevin Kimball, NISYS Corp. • Secretary: Davis Reed, Oak Ridge National Lab. • Treasurer: David Hayes, Los Alamos National Lab. • Executive Committee members • Jim Gulliford (UK), Dennis Mennerdahl (Sweden), Fitz Trumble (WSMS), 2006 • Adolf Garcia (DOE), Maria LeTellier (CSE), Randy Shackelford (NFS), 2007 • Larry Berg (NRC), Tom Burns (MPR), Chuck Harmon (LANL), 2008 • BOD Liaison: Marvin Fertel

  4. NCSD Membership Trends

  5. Professional Demographics

  6. Industrial Demographics

  7. NCSD Budget

  8. NCSD Planning • Strategic and Succession Plans • One-year and five-year plans modeled after current ANS strategic plan

  9. NCSD Contributions to ANS • ANS Position Statements / White Papers • Fact Sheet about criticality accidents for public/news media, white papers on good NCS practices • Other Professional Societies • EFCOG (SAWG) • International collaborations, including initiative for information exchange with Chinese Nuclear Society in progress • Non-Meeting Publication efforts are primarily in ANSI/ANS Standards

  10. Importance of Standards • These are a vital part of the information sharing that has led to fewer criticality accidents • Continuing dialogue among subject matter experts • Accepted by DOE and NRC • De facto rules for this discipline • Provide value to industry – leads to industry participation • Involves many volunteers • Opportunities for young members

  11. Criticality Safety Standards • ANSI/ANS-8.1, Operations with Fissionable Materials Outside Reactors. • ANSI/ANS-8.3, Criticality Accident Alarm System • ANSI/ANS-8.5, Borosilicate-Glass Raschig Rings • ANSI/ANS-8.6, In-Situ Measurements for Criticality Safety • ANSI/ANS-8.7, Storage of Fissile Materials. • ANSI/ANS-8.10, Safety controls With Shielding and Confinement • ANSI/ANS-8.12, Plutonium-Uranium Fuel Mixtures

  12. Criticality Safety Standards • ANSI/ANS-8.14, Soluble Neutron Absorbers • ANSI/ANS-8.15, Special Actinide Elements • ANSI/ANS-8.17, Handling, Storage and Transportation of LWR Fuel Outside Reactors • ANSI/ANS-8.19, Administrative Practices • ANSI/ANS-8.20, Nuclear Criticality Safety Training • ANSI/ANS-8.21, Fixed Neutron Absorbers • ANSI/ANS-8.22, Limiting and Controlling Moderators • ANSI/ANS-8.23, Emergency Planning and Response

  13. Criticality Safety Proposed Standards • ANSI/ANS-8.24,Validation of Calculational Methods • ANSI/ANS-8.25,Criticality Safety Postings • ANSI/ANS-8.26,Criticality Safety Engineer Training and Qualification (submitted to N-16) • ANSI/ANS-8.27,Burnup Credit

  14. NCSD Services to Membership • Professional Development • Scholarships • Peer Recognition/Awards • Student Support • Standards

  15. Professional Development • Professional development workshops • Issue: high costs lead to lower attendance, particularly of young members • Continuing education certificates to attendees of NCSD technical sessions • ANSI/ANS-8.26 proposed national standard on criticality safety engineer (CSE) training and qualification progress nearing completion • Special committee will evaluate formal CSE "Certificate of Completion" pursuant to 8.26.

  16. NCSD Meeting Participation • Average 5-6 sessions at national meeting • Topical meetings every 2 years • Tremendously successful 2005 topical • 170 attendees, $37K profit • Strong international attendance • Still had 5 sessions at this meeting only 2 months later • Issue: Room assignments (need larger room) • Presented problem to PDC/NPC • Requested larger room based on historical attendance • More can still be done on this issue

  17. Topical Meetings • NCSD 2001 Embedded Topical, Reno, NV • International Criticality Nuclear Conference (ICNC) 2003, Japan • NCSD 2005 Topical, Sept. 2005, Knoxville, TN – 75 papers and 170 attendees • ICNC 2007, St. Petersburg, Russia • NCSD 2009 Topical - TBA

  18. NCSD Metrics 2004

  19. Summary • Very successful topical meeting in September • Diverse membership, good international participation • Strong standards committees • Scholarship plan in progress • Strong support for young members

  20. NCSD Requests to BOD • Larger room for governance meetings • Increased diligence by NPC to assure adequate room size for technical sessions based on historical attendance figures • Lower cost for professional development workshops – increase attendance, particularly young members
