Characterization and thermal expansion of Th–10Zr alloy

Studies on Preparation of Thorium-Based Intermetallics in CaCl2 Melt by Electrochemical De-Oxidation Process

“…Metallic fuels are considered the ideal fuel candidate for future generation fast breeder nuclear reactors as these fuels offer several advantageous features that cannot be achieved with other fuel forms. [1][2][3][4][5] Short doubling time, hard neutron spectrum, high breeding ratio, very high burn-up, high fissile and fertile atom density, high thermal conductivity, inherent safety features during transient situations, reprocessing of spent fuel by pyrochemical route etc are various benefits associated with metal fuelled reactors. 2,5 Metallic thorium-based alloys, e.g., Th-U, Th-U-Pu, Th-U-Pu-Zr etc, are regarded as important fuel candidates in metal fuelled nuclear reactors for their excellent physico-chemical, nuclear, and nonproliferation properties.…”
