technical field [0001] The invention relates to a Z-pinch driven fusion fission hybrid energy reactor, which belongs to the technical field of hybrid energy reactors. Background technique [0002] Energy concerns economic security and national security. At present, my country's energy structure with coal as the main energy source is extremely irrational. Extensive use of fossil fuels has caused serious environmental pollution. At the same time, the shortage of energy resources such as coal and oil has aggravated. As a clean and efficient energy source, nuclear energy is one of the most important choices for my country to increase energy supply, optimize energy structure, and address climate change. At present, fission nuclear power plants are facing two problems: first, the world reserves of uranium resources are still limited, and the utilization rate of uranium resources in fission power plants is low; There is an urgent need to develop safe, efficient, environment-frien...

Problems solved by technology

At present, fission nuclear power plants are facing two problems: one is that the world reserves of uranium resources are still limited, and the utilization rate of uranium resources in fission power plants is low;

In the 1970s and 1980s, the United States, Japan, and Turkey conducted a lot of research work on hybrid reactors. Fusion drive methods include magnetic mirrors, tokamak magnetic confinement, and laser inertial confinement. fissile uranium / thorium cladding, but neither goes beyond simple conceptual studies

[0009] 1) The energy efficiency and cost-effective ratio of the laser-driven inertial confinement fusion driver are extremely low. Laser-driven inertial confinement fusion needs to reserve transmission channels for hundreds of lasers, resulting in a complex structure of the spherical target chamber, so that only TRISO fuel pebbles can be used Or liquid fuel, the tritium-producing area uses a liquid tritium breeder, which leads to a complex structure of the entire scheme, molten metal and Flibe put forward high requirements for structural materials

[0010] 2) The scheme adopts multiplied beryllium layers, which is limited by beryllium resources and has no obvious advantages compared with pure fusion

[0011] 3) The concept does not involve the fusion and fission fuel cycle, which is an extremely important part of the reactor

[0015] 2) The invention is only a conceptual study, lacks specific reactor engineering design, and has poor realizability
