The joint evaluated fission and fusion nuclear data library 3.3 is described. New evaluations for neutron-induced interactions with the major actinides \(^{235}\hbox {U}\), \(^{238}\hbox {U}\) and \(^{239}\hbox {Pu}\), on \(^{241}\hbox {Am}\) and \(^{23}\hbox {Na}\), \(^{59}\hbox {Ni}\), 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.

联合评估的裂变与聚变核数据库JEFF-3.3

描述了联合评估的裂变与聚变核数据库3.3。对中子与主要act系元素\（^ {235} \ hbox {U} \），\（^ {238} \ hbox {U} \）和\（^ {239} \ hbox {Pu}的相互作用的新评估\），\（^ {241} \ hbox {Am} \）和\（^ {23} \ hbox {Na} \）上，\（^ {59} \ hbox {Ni} \）给出了Cr，Cu，Zr，Cd，Hf，W，Au，Pb和Bi。它包括新的裂变产率，迅速的裂变中子光谱和每个裂变的中子平均数。此外，还提供了有关放射性衰变，热中子散射，伽马射线发射，中子活化，中子延迟和位移损伤的新数据。JEFF-3.3得到了TENDL项目文件的补充。光子，质子，氘核，tri核，离子和α粒子诱发的反应的库来自TENDL-2017。建模中对不确定性量化的需求导致了许多新的协方差数据用于评估。使用JEFF-3.3库进行的模型计算结果与基准试验的临界度，延迟的中子产率，屏蔽作用和衰减热之间的比较表明，JEFF-3。
