ACE-J50

JENDL-5 ACE library (neutron induced) Release Date: 2022/12/9

These ACE libraries were generated using FRENDY Ver.2.01 and the modified version of NJOY2016.65.
The HEATR module of NJOY2016.65 was used for the calculation of the heating cross section.
FRENDY was used for the other processes.
These ACE files were generated using nuclear data files that reflected updates up to upd-7 released in May 2022.
The XSDIR file was prepared at each temperature.
Please use the XSDIR file(including all temperatures and TSL data) if you want to use all temperature data and thermal scattering law (TSL) data.

Old ACE library

JENDL-5 ACE Library (Up to 20 MeV, T=300 K, For neutronics calculation)

This ACE library was generated by FRENDY Ver.2.00.
The data size of this ACE library is very large (compressed file: 24 GB, decompressed file: 74 GB).
Please remove unnecessary nuclear data files and TSL data files if you want to reduce the data size.

Precautions for use of this ACE library

(1) Data for the KERMA factor are not included in this ACE library.
(2) This ACE library cannot be used for the neutron-photon coupling calculation since there were problems in the processing of the secondary gamma.

Please use JENDL-5 ACE libraries (neutron induced) in ACE-J50 to use these data.
