JAEA has been developed the nuclear data processing system FRENDY from 2013. In this presentation, we explain the overview of FRENDY and comparison of the results processed by FRENDY and NJOY. To investigate the impact of the difference of the processing system on the neutronics calculation, we calculated the ICSBEP benchmark experiments, which are listed in INDC(NDS)-0701, and compared the k-eff values.

To improve the probability table generation, the more sophisticated method was introduced in the calculation methods of the Chi-Squared random numbers and the complex error function. We also investigated the impact of the ladder number on the probability table. We confirm that the calculation speed of new method is 20% faster than that of the old method.

The ACE files of ENDF/B-VIII.0 and JEFF-3.3 processed by FRENDY are compared those by NJOY2016. The differences are found in some nuclides. This presentation explains the detail and the cause of differences. This presentation also explains the overview of the current status of FERNDY development and wrong formats of JEFF-3.3 which are found by FRENDY.

We have compared the processing results of FRENDY to those of NJOY for verification of FRENDY. In this presentation, we focus on the processing of thermal scattering law data. This presentation explains the problems of NJOY. This presentation also explains the implementation of input checking functions for collect nuclear data processing and the recent development of FRENDY, e.g., the development of neutron-induced multi-group cross-section file generation function.

This presentation explains the recent development work of the nuclear data processing code FRENDY. This presentation shows the major new functions in FRENDY version 2 which was released in Jan. 2022 and the overview of the new functions implemented in the revised version which was released in Nov. 2022.
