The Joint Evaluated Fission and Fusion (JEFF) Project is a collaborative effort among OECD Nuclear Energy Agency (NEA) Data Bank member countries to develop a reference nuclear data library for use in different energy applications. These data can be used to help improve the safety and economy of existing installations, as well as to design advanced nuclear reactors and their associated fuel cycles, including radioactive waste management. The JEFF-3.1 library contains several different data types, including neutron and proton interaction data, neutron activation data, radioactive decay data, fission yield data and thermal scattering data. This report describes the initial validation of the complete JEFF-3.1 library for thermal reactors, fuel cycle, storage and reprocessing, fusion technology and intermediate energy applications. It will be useful for scientists and engineers in national laboratories, universities and industry who use basic nuclear data, and is particularly suitable for those who work with application libraries based on JEFF-3.1.
