· JVASP-18503· U3Si2C2

U3Si2C2 is an advanced ceramic compound belonging to the uranium silicide carbide family, representing a mixed-phase material combining metallic and ceramic characteristics. This material is primarily investigated in nuclear fuel and high-temperature structural applications, where its chemical stability and thermal properties make it a candidate for next-generation reactor fuels and accident-tolerant fuel (ATF) cladding systems. Engineers consider uranium silicide carbides as alternatives to conventional UO2 fuels because they offer potential improvements in thermal conductivity and dimensional stability under irradiation in demanding nuclear environments.
