“…The evaluation was generated at the following temperatures: 283.6 The effect of the new evaluation in critical systems is significant, with changes of up to 1200 pcm in sensitive critical experiments [363]. Benchmarking with experiments in the ZED-2 reactor resulted in a reduction of 100-300 pcm in the multiplication factor when the new thermal scattering libraries where introduced [364]. The uncertainty associated to this library was studied for the OPAL reactor [365] using the Total Monte Carlo method [366].…”

The joint evaluated fission and fusion nuclear data library 3.3 is described. New evaluations for neutroninduced interactions with the major actinides 235 U, 238 U and 239 Pu, on 241 Am and 23 Na, 59 Ni, Cr, Cu, Zr, Cd, Hf, W, Au, Pb and Bi are presented. It includes new fission yields, prompt fission neutron spectra and average number of neutrons per fission. In addition, new data for radioactive decay, thermal neutron scattering, gamma-ray emission, neutron activation, delayed neutrons and displacement damage are presented. JEFF-3.3 was complemented by files from the TENDL project. The libraries for photon, proton, deuteron, triton, helion and alpha-particle induced reactions are from TENDL-2017. The demands for uncertainty quantification in modeling led to many new covariance data for the evaluations. A comparison between results from model calculations using the JEFF-3.3 library and those from benchmark experiments for criticality, delayed neutron yields, shielding and decay heat, reveals that JEFF-3.3 performes very well for a wide range of nuclear technology applications, in particular nuclear energy.
