Hybrid reactor cladding for realizing long-term energy amplification by using fast-thermal coupling mixed energy spectrum

Abstract

The invention relates to a hybrid reactor cladding for realizing long-term energy amplification by using a fast-thermal coupling mixed energy spectrum, which comprises a first wall, a fast fission region, a non fission neutron multiplication area, a thermal fissile area and a tritium breeding area. The structure of the hybrid reactor cladding is the first wall, the fast fission area, the non fission neutron multiplication area, the thermal fission area and the tritium breeding area in sequence from inside to outside. The cladding adopts the way that helium flows circumferentially and is cooled step by step. Helium enters into the cladding from a side pipeline of the first wall, enters into a fast neutron fission area transversely through the cladding after cooling the first wall, enters into the non fission neutron multiplication area and the thermal fission area from the other side of the cladding after cooling the fast neutron fission area and then enters the side pipeline of the first wall and flows out. Liquid lithium lead in the tritium breeding area enters into the cladding from the upper part of the cladding and flows out from the lower part and brings out heat and tritium relying on the flow. According to the hybrid reactor cladding, the long-term energy amplification, higher power generation efficiency and better safety can be achieved.

Description

technical field [0001] The invention belongs to the cladding design field of fusion and fission hybrid reactors, and in particular relates to a cladding of a hybrid reactor that realizes long-term energy amplification by using a fast-thermal coupling hybrid energy spectrum method. technical background [0002] The principle of the fusion-fission hybrid reactor is to use the high-energy neutrons generated by the deuterium-tritium reaction in the fusion core to drive the nuclear material in the fission cladding to initiate a fission reaction, and use the energy generated by the fission reaction to generate electricity. The cladding operates in a subcritical state and is inherently safe. In addition, compared with conventional fission reactors, fusion-fission hybrid reactors can lower the requirements for the quality of fission nuclear fuel, and can use depleted uranium, spent fuel, and thorium, which cannot be directly used by current fission reactors, and will not compete wit...
