Summary
The accelerated deployment of advanced nuclear reactors—such as small modular reactors (SMRs), Generation IV fast-spectrum, molten-salt, and high-temperature gas-cooled concepts—is pivotal to achieving deep-decarbonization targets and ensuring resilient, low-carbon baseload power. These designs promise enhanced safety, flexible grid integration, and resource utilization, yet their neutronic and thermal-hydraulic behaviors depart significantly from legacy light-water fleets. Multiphysics phenomena, including strong coupling between neutron kinetics, coolant flow, and heat transfer, introduce new challenges in reactor licensing, operation, and safety assessment.
This Special Issue provides a dedicated forum for cutting-edge research on coupled neutronics and thermal-hydraulic analysis of advanced reactors. We solicit original research papers and comprehensive reviews that advance multiscale modeling, high-fidelity simulation, experimental validation, and code development. Contributions should address fundamental physics, engineering methodologies, regulatory frameworks, and practical deployment experiences.
Suggested topics include:
· Advanced Reactor Design and Analysis;
· Reactor Physics, Thermal-hydraulics, and Safety;
· Nuclear Fuel and Materials;
· Uncertainty Quantification;
· CFD Analysis of Advanced Reactor;
· Advanced thorium uranium/uranium plutonium fuel cycle scheme;
· Transient accident safety of advanced nuclear energy systems;
· Research on Multi-physics Coupling of Advanced Nuclear Energy Systems;
· Radiation protection and environment protect;
· Other related topics in the field of advanced nuclear energy.
By consolidating the latest theoretical, computational, and experimental advances, this Special Issue aims to accelerate the safe, efficient, and economic deployment of next-generation nuclear technologies.
