In the design of structural components for next-generation nuclear plants, physics-aware modeling is critical to capture the effect of transients in realistic environmental conditions. These simulations typically exceed the computational budget allowable for a design tool. The computational expense of typical physics-informed simulations is bypassed through the use of a combination of modeling techniques. A constitutive model of HT-9 steel is used in a VPSC framework to generate a database of simulations of thermal and irradiation creep. A reduced order model (ROM) is designed to replicate the relations contained in the database. Finally, the ROM is linked to a finite element software MOOSE to allow rapid simulations of cladding designs.
