Multiphysics Modelling of the Molten Salt Fast Reactor using NekRS and the Fission Matrix Method
Maximiliano Dalinger, Elia Merzari, Saya Lee
The Molten Salt Fast Reactor (MSFR) has the particularity that the coolant is also the fuel, which tightens the coupling between neutronics and thermal hydraulics as the fuel circu…
Analysis of Fission Matrix Databases using Temperature Profiles obtained from High-Fidelity Multiphysics Simulations
Maximiliano Dalinger, Elia Merzari, Saya Lee +1
The Fission Matrix method is used to perform fast and still accurate neutronics simulations. It relies on precalculated databases obtained through a Monte Carlo simulation. To repr…
Toward Developing Machine-Learning-Aided Tools for the Thermomechanical Monitoring of Nuclear Reactor Components
Luiz Aldeia Machado, Victor Coppo Leite, Elia Merzari +4
Proactive maintenance strategies, such as Predictive Maintenance (PdM), play an important role in the operation of Nuclear Power Plants (NPPs), particularly due to their capacity t…
High-Fidelity Modelling of the Molten Salt Fast Reactor
Maximiliano Dalinger, Elia Merzari, Saya Lee +1
The Molten Salt Fast Reactor (MSFR) is one of the six GEN-IV reactor designs. In the MSFR, the liquid fuel is the coolant, which moves throughout the primary circuit. This complex…
Multiphysics Modeling of SNAP 10A/2 Space Reactor with Cardinal
Maximiliano Dalinger, Elia Merzari, Tri Nguyen +2
The SNAP 10/A nuclear-powered satellite was launched into space in 1965. The present work discusses the development of a coupled neutronic-thermal hydraulics model with the high-fi…
