EXFOR and CINDA Verification procedures and IAEA NDS web interface facilitates new and revised data entry EXFOR: In 2008, 50 new works and 147 revised experiments related to neutron induced data. 145 new and 59 revised experiments for charged particles induced data. In 2009, 4 months, 28 new works and 137 revised for the neutron induced (WPEC SG30). 56 new and 17 corrected charged-particle induced experiments.

Nuclear Data services, Rugama 9 WPEC subgroup 30 on EXFOR Quality and accessibility assessment of EXFOR Discussions on a better completeness on photonuclear data and certain old data not yet included in EXFOR. Maintenance of the EXFOR database. Faster response to trivial corrections. Verified computational format (C4) to be used in codes.

JEFF project: Release of the JEFF General Purpose Neutron induced Fission Yields U-235, MF=8 Nuclear Data services, Rugama 11

Nuclear Data services, Rugama 12 JEFF Report 22: The JEFF Nuclear Data Library Published in May 2009

Nuclear Data services, Rugama 13 JEFF Report 23 “Validation of the JEFF-3.1 and JEFF3.1.1” Thermal reactors (e.g. U-238, LEU-COM- THERM-007) Fast reactors Fuel cycle, storage and reprocessing Fusion other applications,(e.g. Fe, neutron leakage)

Nuclear Data services, Rugama 14 Plans for JEFF-3.2  Revise U-235 and U-238 (emphasis on high energy region)  New evaluation for the Pu-239  More evaluations with covariance data (e.g., Pb, Bi)  Latest version of European Activation file (EAF-2009…)  Photonuclear data for all isotopes when available  New evaluations for Tungsten, Hafnium and Tantalum.  New evaluations using the measurements from Geel: Pb, Bi, Am-241 and Am-242  Integrate the Th-232 evaluation available from IAEA.  Radioactive Decay data library (about 130 new/revised evaluations) A tentative date for the release is 2010

Nuclear Data services, Rugama 15 New version of the NEA data display software Latest version available through Java Web Start technology (1/3 total users) All libraries processed coherently with NJOY BTSPEC code from Tobias integrated in JANIS to display beta spectral ray shapes Display of Photonuclear data (MF12-15) Improved EXFOR coverage
