Nuclear data processing is an important interface between evaluated nuclear data library and neutronics transport codes. JAEA developed a new nuclear data processing code FRENDY in order to process the evaluated nuclear data library JEND. JAEA released FRENDY version 1 as an open source software under the 2-clause BSD license. The current version of FRENDY can generate ACE formatted files for continuous energy Monte Carlo calculation codes such as MCNP and PHITS. It uses the same processing method as NJOY because the implementation of the conventional method is an important step to develop the new code. For verification, we compared the processing results of FRENDY with those of NJOY and confirmed FRENDY provided us with almost the same outputs as NJOY. In this presentation, we explains the overview and a future plan of FRENDY.
