US Nuclear Data Program Budget Briefing – February 9, 2015 Structure & Decay Databases ENSDF – the evaluated product of NSDD network  15 mass chains published in Nucl. Data Sheets (17/17 in prior 2 years)  Some other work is added to ENSDF without publication  31 mass chains in review pipeline as of 1/1/2014  Only 12 new A-chain evaluations entered the review process in 2014 NSR – up to date primary source of references with keywords.  3130 new references added in  B. Pritychenko, B. Singh, E. Betak (Bratislava), J. Totans XUNDL – current compilation of major journal articles in ENSDF format.  McMaster – 318, TUNL – 53, ANL – 8, LBNL+UCB - 30, ORNL - 37, BNL – 5 (New Contributors)  Estimate total 0.5 FTE (perhaps a low estimate)  Activity contributes to future ENSDF evaluations  Requires increased input from network evaluators to survive

Bright Spots Favorable DOE program review in June New interest from International sites who may contribute –Japan –GSI Concerns from last year are being addressed: –Loss of trained postdoc evaluators –Need for new staff hires –Network appears to be shifting away from multiple strong centers  MSU (with ANL) hired Jun Chen (former ANL postdoc)  in support of Structure compilation and evaluation (XUNDL/ENSDF)  UC-Berkeley hired Lee Bernstein  in support of Structure compilation (XUNDL)  Contracts with Coral Baglin and Rick Firestone for ENSDF evaluations US Nuclear Data Program Budget Briefing – February 9, 2015

Structure and decay data concerns ENSDF A-chain submissions are falling  12 A-chains were submitted in 2014  Jag Tuli estimates we need around 20 A-chains/year Shrinking budgets are impacting workforce  ANL has fallen to 80% (USNDP) support for primary evaluator.  Potential Furlough; unable to participate in meetings, workshops, training in FY15  Historic Placement with NE complicates finding relevant 0.2 FTE  Loss of support for Nuclear Data Sheets publication preparations  Administrative assistant retirement/(no replacement) at NNDC  Requires more effort from Evaluators  TUNL administrative assistant will contribute some of her time Aging ENSDF evaluators – Same story  Retired/consultant funding = Experience and Productivity (can’t last forever)  Baglin, Brown, Firestone, Martin, Singh US Nuclear Data Program Budget Briefing – February 9, 2015

Structure and decay data concerns ENSDF needs increased national and international expansion and focus on productivity Low productivity could reach a critical point for maintaining the quality of the ENSDF database and loss of NDS journal. We a network strategy to support best staff hires to ensure stability and quality of the core activities (NSR/ENSDF/XUNDL) Critical assessment of the breadth of present activities (USNDP review panel/ white paper) Budgets – support activities with the highest impact US Nuclear Data Program Budget Briefing – February 9, 2015
