Nuclear fuels and reactor-core components experience a significant amount of particle irradiation during their operational lifetime. The accumulating radiation damage has a strong influence on the material properties both directly and indirectly by impacting the microstructural evolution, which in turn modifies the neutron transport characteristics of the material.
Based on INL’s Multiphysics Object-Oriented Simulation Environment (MOOSE) framework, a damage production model has been developed that can use neutron reaction data obtained through a concurrent neutron transport simulation to obtain spatially resolved knock on atom energy and mass distributions to initiate cascade simulations using a binary collision Monte Carlo code. The discrete cascade data is used as a source term in a phase field microstructure simulation component.
We demonstrate this capability on heterogeneous microstructures such as surrogate systems of oxide dispersed steels under irradiation.
