Reactor Safety: Monte Carlo based High-Fidelity Methods
The goal of Monte Carlo based high fidelity methods is to perform simulations of pin/fuel assembly clusters or whole cores using Monte Carlo codes and taking into account local thermal hydraulic conditions predicted by subchannel codes. Such developments are needed due to:
- Lack of experimental data about local safety relevant parameters of reactor cores e.g. pin power, cladding temperature, fuel temperature, etc.
- Available computer power (HPC) and parallel capability of MC and TH codes, paves the way for very-detailed coupled Neutronic/TH simulations not possible before
Optimized high fidelity MC/TH simulations will deliver:
- Reference solutions to check deterministic codes e.g. for power distribution, depletion problems taking into account thermal hydraulic feedbacks
