Description

JADE is a python framework that makes it easy to automatically pre-process, run and post-process large numbers of neutronic simulations which are used for the Verification and Validation (V&V) of nuclear data libraries and Monte Carlo codes.

Last year, at the first edition of the “Fusion Neutronics Meeting”, the new architecture of JADE v4 was presented. The complete rewriting of the software greatly simplifies the addition and maintenance of benchmarks that are part of the JADE suite and allows a full native integration of OpenMC into the framework.

During this last year, the project entered a phase of consolidation which focused on the quality of the post-processing, resolution of bugs and quality-of-life improvements for JADE users. The latest version of JADE (v4.4.0) was employed to perform a deep V&V assessment of the FENDL 3.2c (new recommended library for ITER project) using both MCNP and OpenMC. The work presents the main differences found between FENDL v3.2c and other major libraries as well as differences between MCNP and OpenMC results.
