The FUDGE translation of the TENDL-2021 library from ENDF-6 to GNDS

The conversion of TENDL libraries from ENDF-6 to GNDS is an indirect approach to making the output from the TALYS nuclear model code system available in the new Generalized Nuclear Data Structure (GNDS) format. The LLNL processing code FUDGE, was used to translate TENDL-2021 from ENDF-6 to GNDS. An overview of this work is provided and the different warning and error messages are discussed.
