U7Mo

U7Mo is a uranium-molybdenum alloy developed primarily for nuclear fuel applications, particularly in research and test reactors where high uranium density and superior performance are critical. This material is notable for its ability to achieve high fissile density while maintaining acceptable metallurgical properties, making it a preferred choice in advanced reactor fuel designs where space constraints or neutron economy drive material selection. As a specialized nuclear material, U7Mo is subject to strict regulatory oversight and is used almost exclusively in government and international research institutions rather than commercial power reactors.
