SESI/LCOS - Validation of thermal-hydraulics and neutronics coupled Molten Salt Reactor system code with CATHARE3

Location: CEA Cadarache – LCOS (SESI). Context: fast-spectrum MSR stability in natural circulation; validation of a 1D simplified Python tool against CATHARE3 (with MSR neutronics capability). Work: provide CATHARE3 reference deck; compare time-evolution behaviours, analyze discrepancies, assess limits of the simplified tool, propose code/physics improvements. Tools: Python, CATHARE3. Keywords: Molten Salt Reactor, CATHARE3, validation, thermal-hydraulics, Python. Thesis opportunity: No.
