About Valar Atomics
At Valar Atomics, we're redefining what's possible in energy. Our mission is to make clean, high-temperature nuclear power scalable—unlocking abundant energy for industry, hydrogen, and next-generation manufacturing. We are a team of builders, engineers, and operators who believe nuclear energy should be fast to deploy, factory-made, and built for the real world. Our first pilot plant in Orangeville, Utah will demonstrate how advanced nuclear systems and fuel fabrication can power the future. Joining Valar Atomics means becoming part of a company where autonomy, ownership, and impact exist at every level.
The Team
The ModSim Engineering Group is a dynamic analysis and engineering group that provides the analytical foundation for reactor and plant design, delivering high-fidelity computational analysis, integrated directly into the engineering design process.
The group responsibilities spans:
- Neutronics and reactor design;
- Thermal-hydraulics systems analysis covering steady-state and transient performance of the complete system; and
- Computational fluid dynamics and finite element analysis for detailed flow, thermal, and structural integrity assessment.
