Intensive fast neutron sources using deuteron accelerators have been proposed for various applications. To contribute to the design study of such neutron sources, a deuteron nuclear data library for 6,7 Li, 9 Be, and 12,13 C up to 200 MeV, JENDL/DEU-2020 is developed. Evaluation of JENDL/DEU-2020 is performed by employing the code system DEURACS with particular attention to neutron production data. Toward the evaluation of JENDL/DEU-2020, some modifications are made to DEURACS. Validation of the library is performed through simulation with the Monte Carlo transport calculation codes. From the simulation, it is shown that calculation results based on JENDL/DEU-2020 reproduce measured neutron production data well in incident energies up to 200 MeV. The new library is expected to make a large contribution to diverse design studies of deuteron accelerator neutron sources.
