Distinct from conventional power generation methods, a nuclear reactor is characterized by harsh level of irradiation, very high operating temperature, and extremely corrosive environments. The behavior of fuels, materials and systems for fission reactors is thus complex, due to the changes that the extreme environments generate on them. These kinds of changes may be seldom seen in other engineering disciplines, but this poses demanding requirements over reactor fuels, materials and systems. The design of reactor fuels, materials and systems subject to extreme environments is a major obstacle to enhance reactor safety and economic performance of nuclear power systems. It’s also an important factor in increasing innovation for current reactor operation improvement and future reactor design optimization.
To address the challenges related to extreme reactor environments, research activities from complementary fields are solicited, such as dealing with nuclear fuels/materials performance, thermal hydraulics, severe accident analysis and neutronics under reactor extreme environments. Both experimental and computational approaches can significantly contribute to advances in reactor fuels, materials and systems under extreme environments.
This Research Topic focuses on all aspects of experimental and modelling/simulation approaches for a deeper understanding of reactor fuels, materials and systems under extreme environments, including, but not limited to:
• Multiphysics modelling and simulations of nuclear fuels and materials
• Multiscale (from atomic to engineering scales) modelling and simulations of nuclear fuels and materials
• Experimental and computational accident tolerant fuels
• Reactor thermal hydraulics to address concerns for reactor extreme conditions
• Neutronics and reactor engineering analysis under extreme environments
• Severe accident analysis and management to lower the effects from reactor extreme environments
• Reactor system analysis to develop innovative systems with better reactor environments
• Fundamental multi-phase flow and heat/mass transfer studies under reactor high temperature and/or corrosive environments to help understand the physics and mechanisms behind
• Other topics not mentioned here but related to these areas
The editors encourage submissions of original research articles, short communications and review articles that cover the above-mentioned topics.
