Status and plan of JENDL will be presented. After the release of JENDL-4.0 in 2010, six special purpose files have been developed. Four of them were already released and two are under preparation for the release. New decay and yield data for fission products were released as JENDL/FPD-2011 and JENDL/FPY-2011 in 2011, respectively. JENDL-4.0/HE released in 2015 includes proton and neutron induced reaction data up to 200 MeV. Comprehensive decay data were released as JENDL/DDF-2015 which contains data for 3,237 nuclides. New photonuclear reaction data JENDL/PD-2016 and an activation file JENDL/AD-2017 are under preparation for release. Regarding general purpose file, two activities are in progress. One is JENL-4.0u which is created for maintenance of JENDL-4.0 and the other is development of next version of JENDL. For the next JENDL, evaluation for light nuclei and structure material are in progress. It is planed that next version of JENDL will be JENDL-5 which contains nuclear data for all nuclei having natural abundance. Addition of covariance data will be one of the main targets.

In molten salt reactors and small modular reactors (SMRs), the use of graphite and CaH
as moderators is being considered, respectively. Thermal neutron scattering law of moderator material has a large influence on the reactor core design. In addition, charged-particle emission reactions such as (n,p) and (n,a) on K-39 in molten salt and on Cu-63 in heat pipes of SMRs can produce nuclides that are problematic for waste management. Therefore, accurate data on thermal neutron scattering laws for graphite and CaH, and charged-particle emission reaction cross sections for K-39 and Cu-63 are important for the core design of these innovative reactors. Based on the above, we have been studying the evaluation method of these data. The progress to date will be presented.
