Abstract
The invention belongs to the technical field of nuclear power generating equipment, and in particular relates to a novel thorium base reactor assembly. The assembly comprises a neutron generating device, a core partition device and a safety control device. An accelerator generates protons to bombard the lead target nuclear to generate neutrons; 232Th absorbs the neutrons for decay to generate and accumulate fissile nuclide 233U; when the 233U accumulates to a certain amount, fission will occur. At the same time, 235U absorbs the neutrons passing through a thorium fuel zone for fission, so as to produce energy and neutrons. The invention can realize value addition of the thorium fuel, so as to solve the shortage of nuclear resource in our country. The invention realizes the value addition of the thorium fuel; and usage of the thorium fuel produces less radioactive materials. The core employs the uranium fuel to provide neutrons for the thorium fuel, as well as reduce the work load of the accelerator.
