With the High Priority Nuclear Data Request List’s (HPRL) recent upgrade to a user-friendly web platform, the NEA entered a new era of nuclear data management. The upgrade allows the modernisation of handling nuclear data and improves access for international research collaboration. This change opened new opportunities for increased transparency and reproducibility of nuclear codes at the NEA Data Bank. The most recent addition to the collection of open-source, publicly available tools is the Dragon / Donjon package suite developed at Polytechnique Montreal under the lead of Professor Alain Hébert.
The Dragon / Donjon code is a suite of nuclear reactor simulation that model neutron behaviour. Hosting the code on the NEA infrastructure enables the addition of quality assurance and automated testing capabilities using GitLab Continuous Integration (CI).
For the first time since its inception, users can directly share feedback or propose code improvements in a transparent and publicly accessible manner, as well as benefit from measures ensuring consistent behaviour via an automated set of tests. Furthermore, Dragon can be used in downstream projects and codes in a reproducible way with clearly specified version dependencies. This permits the transparent usage and integration of Dragon in large-scale processing projects, such as the Joint Evaluated Fission and Fusion (JEFF) nuclear data library.
