Special thorium-plutonium hydrides for fast treatment reactor

摘要

A lightly hydrided/deuterated metallic plutonium-thorium fuel for use in a fast fission pool-type nuclear reactor cooled with liquid metal coolants, including lithium-7 lead eutectic, lead bismuth eutectic or lead. When so used, plutonium-239 is consumed, and merchantable heat is produced along with fissile uranium-233, which can be denatured with uranium-238 and used in light water reactors as fuel.

1. A clad metallic nuclear fuel alloy for use in the fast or epithermal neutron spectrum that efficiently fissions or transmutes isotopes present in spent light water reactor fuel, said nuclear fuel alloy comprising:
75-95% fertile metallic thorium; 5-25% reactor grade fissile plutonium and associated unseparated transuranics; and protium; wherein said metallic nuclear fuel alloy is enclosed in stainless steel cladding and doped with protium such that the ratio of thorium atoms to protium atoms is between approximately 6:1 and 4:1, inclusive, with the exact ratio of fertile to fissile material being a function of reactor power and such that said fuel fissions in the elevated epithermal neutron spectrum or the fast neutron spectrum and consumes and destroys plutonium-239 and other plutonium isotopes in reactor grade fissile plutonium along with the associated unseparated transuranics from spent light water reactor fuel.
