Abstract

The invention discloses a tritium generation module of a fusion-fission cladding system. The tritium generation module of a fusion-fission cladding system includes a Zr-cladding housing with a U-shaped cross section and a spherical Li4SiO4 value-added agent, wherein a plurality of separator plates is arranged in the Zr-cladding housing, and the cross section of each separator plate is U-shaped; flow channels and helium channels are formed among the separator plates; the flow channels and the helium channels are arranged at intervals; and the helium channels are filled with the spherical Li4SiO4 value-added agent. The technical aim of the tritium generation module of a fusion-fission cladding system is to provide a tritium generation module which can improve neutron utilization, of the fusion-fission cladding system.

Description

technical field [0001] The invention relates to the technical field of nuclear fusion and fission reactors, in particular to a tritium-producing module of a fusion and fission cladding system. Background technique [0002] Energy is the material basis of modern economic and social development, and it is also an important constraint factor for economic and social development. Energy security is related to economic security and national security, and the impact of energy consumption on the ecological environment is becoming increasingly prominent. As the world's most populous country and the largest developing country, China is already the world's second largest energy producer and consumer. Facing the increasingly tense energy situation, my country vigorously advocates energy saving and consumption reduction, and continuously improves the production and utilization efficiency of existing energy. my country's current energy consumption is dominated by coal, not only the suppl...

Problems solved by technology

The utilization efficiency of uranium resources in thermal neutron reactors is only 1%, and the continuous large-scale development in the medium and long term is limited by the low utilization efficiency of uranium resources

Fast neutron reactors can increase the utilization efficiency of uranium resources to 60%. At present, the technology development is relatively mature, and it is expected to become the main nuclear energy system of the new generation. Separation and separation of uranium and plutonium, and there is a restrictive relationship between fuel multiplication speed and safety, so the fuel multiplication cycle is very long, and it will be difficult to deploy on a large scale in the middle of this century or even longer

In the foreseeable period of time, the commercial energy application of pure fusion cannot be realized, mainly due to the radiation resistance of materials and the high Q (the ratio of the energy released by fusion to the heating energy required to achieve fusion) required for commercial power generation ) is difficult to limit, and in the long run, it will also be limited by tritium resources

The hybrid reactors of the traditional concept mainly carry out nuclear fuel multiplication and nuclear waste transmutation. Most of them have the characteristics of complex system, need for fuel reprocessing, poor economy, and limited by the scientific and technological problems of pure fusion core. Therefore, the traditional function positioning Mixed piles are difficult to achieve greater development
