Moltres

An open-source MOOSE application for the simulation of molten salt reactors

Moltres is a finite element-based multiphysics reactor simulation tool for molten salt reactors (MSRs) and other advanced reactors in various dimensions and geometries. Moltres is built on the MOOSE framework and provides multiphysics capabilities to accurately model delayed neutron precursor drift and the strong temperature feedback effects inherent in MSRs. Users have the flexibility of setting up fully coupled solution schemes in which all variables are solved in a single monolithic system, or tightly coupled solution schemes by arbitrarily segregating systems of equations corresponding to separate physics. As a MOOSE-based application, Moltres can also scale efficiently on high-performance computers.
