  2. Update of the IRDF-2002 (rel. 2005) • IAEA CM held in 2007,2010: • INDC(NDS)-0575 (2010) and • INDC( NDS)-507 (2007) • Zolotarev evaluations for RRDF • (partially supported by IAEA/NDS) • INDC(NDS)-0526, • INDC(NDS)-0546, • INDC(NDS)-0584, • IAEA Standards + ENDF/B-VII.0+cov • JENDL-4 ? • Model covariance calculations: TENDL • Use for the extension of the energy range • Conclusions and outlook

  13. Conclusions • International Reactor Dosimetry File IRDF-2002 released in 2005 [1]; • library contains 66 dosimetry reactions. Update is needed. • New IAEA dosimetry library (IRDFF) released for testing (74 react + 3abs) • New suitable evaluations including covariances became available • - IAEA neutron cross-section standards [2] combined with • ENDF-B/VII.1 evaluations [3], JENDL-4 evaluations, and • Zolotarev evaluations [4-6]. • 37 dosimetry reactions updated and compared to measurements in • ENDF-B/VII.0 235U thermal and 252Cf fast neutron fields. • Formal extension of all evaluations up to 60 MeV of incident neutron • energy using TENDL-2010 [7] done.
