Westinghouse is developing the latest generation of nuclear fuels often labelled as accident tolerant fuels (ATFs). These fuels are not only characterized by their superior tolerance to both design basis accidents and beyond design basis accidents, but also their significant improvement in terms of economy to operate. Leading candidates in Westinghouse’s ATF effort include U3Si2 and UN fuels, clad within coated
Zr-based alloys or SiC-SiC composites. Test reactor data, being gathered in an international effort supported by a number of organizations including the IAEA, is being complimented with modelling work in order to efficiently license these new fuels for operation in the world’s light water reactor fleet. Modelling methods such as atomic scale simulation is being used to develop material models that can be validated with experimental data – hence provide a mechanistic framework to perform fuel rod analysis.
