The Serpent-2 software is a three-dimensional continuous-energy neutron and photon transport code, developed at the Technical Research Centre of Finland (VTT) (Leppänen, 2015), and is one of the most requested software programs from the Nuclear Energy Agency Data Bank (NEA DB). The NEA Data Bank also facilitates the production and distribution of the Joint Evaluated Fission and Fusion (JEFF) Nuclear Data Library (Plompen et al., 2020), a collaborative effort among its member countries to provide evaluated nuclear data libraries for a variety of fission and fusion applications. More broadly, the NEA supports international nuclear data collaboration between its member countries through the Working Party on International Nuclear Data Evaluation Co-operation (WPEC), providing a framework to promote the exchange of information on nuclear data evaluations, measurements, nuclear model calculations, validation, and related topics between the evaluation projects.
