  1. NNDC Report to NSDD’2007 Pavel Oblozinsky National Nuclear Data Center Brookhaven National Laboratory oblozinsky@bnl.gov Brookhaven Science Associates

  2. ENSDF Evaluation Activity • NNDC Responsibility: 113 mass chains • Manpower status: 3.40 FTE (NNDC staff + Browne, Nica, Reich) • Evaluated/published since June 2005: 20 + 28 mass chains

  3. ENSDF Evaluation Activity, continued

  4. Other Activities Directly Related to ENSDF • ENSDF Evaluation Reviews: 19 mass chains reviewed • Tuli 9, Burrows 2, Sonzogni 2, Winchell 1; Browne 1, Reich 4 • ENSDF Evaluation Processing • On average ~22 mass chains in production pipeline • Nuclear Data Sheets published regularly, no more recent references • ENSDF Maintenance: 3,016 nuclides (June 1, 2007) • Updated continuously, distributed twice per year • ENSDF Analysis & Checking Codes (more details J. Tuli) • Maintained and improved, remaining codes converted to Fortran 95 • BrIcc-2.0 released (with Kibedi et al) • ENSDF Training and Mentoring • Burrows mentors Ninel Nica (Texas AMU) • Sonzogni mentors and collaborates with Abriola (now IAEA, A=94) • Visitors to NNDC: Gupta in 2005 (A=266-294, Burrows), Basu in 2006 (A=150, Sonzogni)

  5. Nuclear Wallet Cards and NuDat • Nuclear Wallet Cards • 7th edition, 10,000 copies produced in June 2005 • ~6,000 copies distributed so far, continues to be very popular product • NuDat • By far the most successful database if measured by web retrievals • NuDat-2.2 and NuDat-2.3 developed over the last 2 years • Responsible for ~60% of retrievals from the NNDC web serves, in absolute terms retrievals increased by almost factor of 3 since new service introduced in April 2004 • More details A. Sonzogni

  6. Nuclear Science References • Status • 8,581 references added during June 2005 – May 2007 • Responsible for keywording of 3 European journals (NPA, PLB, EPJA) is Mark Kellet, IAEA, since September 2005 • Several changes and improvements in the database and web • More details J. Tuli • New Database Manager • Dave Winchell left after ~10 years of dedicated service • Manojeet Bhattacharya, PhD from Notre Dame in 1999, formerly at NASA, in charge of NSR since June 1, 2007, after 6-weeks overlap with Dave

  7. Computer System and Web Service • Computer system • No major changes, focus on reliability and cyber-security • Second web server, software upgrade (Linux, DBMS), more storage capacity • Major upgrade expected in 2009) • Web service • Continuous improvements (NuDat, NSR, Logft, …) • Several new products (Chart of Nuclides, Qcalc, … • In 2006 major milestone reached: 1 Million retrievals
