Investigated accident tolerant nuclear fuels Small dish are fuels with enhanced thermal conductivity, which can withstand the loss of coolant for a longer time by allowing faster dissipation of heat, thus lowering the centerline temperature and preventing the melting of the fuel.Traditional nuclear fuels have a very low thermal conductivity and can be significantly enhanced if transformed into a composite with a very high thermal conductivity components.In this study, we analyze the thermal properties of various composites of mixed oxides and thoria fuels to Protective Gear improve thermal conductivity for the next generation safer nuclear reactors.
