Summary
The objective if this project is to accurately model reactivity feedback mechanism in VTR design and safety calculation using validated high-fidelity multiphysics modeling with a coupled code system that includes MCNP, CINDER90/ORIGEN-S, TRACE-Na, PARCS, and BISON.
- Steady-State and Transient Calculations for Design and Safety Analysis
- Accurate Modeling of Thermo-Mechanical Behavior and associated Reactivity Feedback
- Transient Calculations Initialized with Steady-State Results
- Transient Cross Section Expansion
