3. Pavel Oblozinsky NSDD’07, St. Petersburg June 11-15, 2007 3 Membership National labs (ANL, BNL, LBNL, LANL, LLNL, ORNL) Universities (TUNL, NIST, McMaster) Total manpower ~ 23.5 FTE

4. Pavel Oblozinsky NSDD’07, St. Petersburg June 11-15, 2007 4 USNDP Organization USNDP Chair: P. Oblozinsky, BNL Standing Working Groups Reaction data, chair T. Kawano, LANL Structure and decay data, chair C. Baglin, LBNL Task Forces Nuclear data for astrophysics, chair M. Smith, ORNL Nuclear data for homeland security, chair D. McNabb, LLNL

5. Pavel Oblozinsky NSDD’07, St. Petersburg June 11-15, 2007 5 Major activities Archival of databases & data dissemination25% Nuclear structure and decay data40% Nuclear reaction data20% Coordination & support15% Major products ENSDF database Evaluated nuclear structure & decay data Produced together with the NSDD network ENDF database Evaluated nuclear reaction data Produced together with the Cross Section Evaluation Working Group

6. Pavel Oblozinsky NSDD’07, St. Petersburg June 11-15, 2007 6 Nuclear structure data activities ENSDF, NSR, XUNDL, NuDat, Nuclear Data Sheets, Nuclear Wallet Cards, … Sponsored solely by USNDP (DOE Office of Science) Users are primarily from basic nuclear science Nuclear reaction data activities ENDF, CINDA, CSISRS, … Sponsored partly by USNDP (DOE Office of Science) Other sponsors contribute via CSWEG Considerable leverage to USNDP ~ factor of 10 Users are primarily from applied nuclear technology

7. Pavel Oblozinsky NSDD’07, St. Petersburg June 11-15, 2007 7 Issue: ENSDF manpower (age of U.S. evaluators) Positive change since 2005, new part time evaluators: - N. Nica, BNL/TA&M - Postdoc in ANL - Postdoc in TUNL - Postdoc expected in McMaster Status 2005

8. Pavel Oblozinsky NSDD’07, St. Petersburg June 11-15, 2007 8 USNDP Users Forum intends to strengthen dialog with the user community, get feedback and new ideas; introduced in 2005 Format: 4 prominent scientists invited to USNDP annual meeting for a half-day session consisting of their talks and discussions 2005, organized by D. Winchell I.Y. Lee, LBNL M. Carpenter, ANL P. Cottle, Florida State University J. Millener, BNL 2006, organized by A. Sonzogni C. Baktash, ORNL B. Tsang, Michigan State University A. Mengoni, IAEA, Austria & CERN (n-ToF measurement of neutron cross sections) G. de France, GANIL, France 2007, organized by A. Sonzogni G. Bertsch, Institute of Nuclear Theory, University of Washington 3 other speakers, including 1-2 from Europe, to be determined Users Forum

9. Pavel Oblozinsky NSDD’07, St. Petersburg June 11-15, 2007 9 Nuclear Data Sheets Nuclear Data Sheets continues to be important vehicle for publishing ENSDF evaluations (~ 2,500 - 3,000 pages per year) Small part is available for non-ENSDF papers 2005: Recent References discontinued, available on NSR webpage 2006: Special issue on ENDF/B-VII.0 library published in December, use of ENSDF in ENDF is very important!, may become the most cited NDS issue ever 2007: Several papers related to ENDF/B-VII.0 considered for December issue (uranium evaluations by LANL, evaluation reaction model code EMPIRE by BNL et al., …) NDS modernization is underway (discussed by J. Tuli and B. Singh)

10. Pavel Oblozinsky NSDD’07, St. Petersburg June 11-15, 2007 10 Bad news USNDP feels increasingly uncomfortable with the weak international (European) contribution to ENSDF evaluations, but there is no much it can do about this Good news DOE Office of Science remains committed to ENSDF In conclusion I can offer bad news and good news
