Seaborg External multiphysics Architecture for Licensing and Ip development (E!11837 SEALION) Of Nuclearreactors
Research Project, 2018 – 2021

In SEALION, we will develop a multiphysics software tool for modelling the complex dynamical behaviour of advanced nuclear reactors, with particular focus on molten salt reactors (MSRs). The tool will use high performance computing techniques. It will comply with current regulations by using existing licensed mono-physics tools that will be externally coupled.

The disruptive element of SEALION is that the coupling is produced completely externally, which means that the coupling does not modify the involved source codes. The extensive verification and validation of such tools will thus be maintained. Since the external coupling can be considered as a data analysis and exchange process, performed as post-processing of existing and licensed tools, SEALION will enable licensing of MSRs under the current regulatory framework, thereby accelerating their commercialisation.
