Nuclear fusion device where nuclear fusion is achieved through the compression of high-temperature plasma between a target and a high-speed bullet

摘要

The present invention relates to a nuclear fusion apparatus which compresses, greater than or equal to 100 times, deuterium and tritium plasma having the temperature of higher than or equal to 1 million °C between a target and a high-speed bullet having a concave front and the speed of greater than or equal to 7 km per second in order to make the temperature of the plasma higher than or equal to 100 million °C, thereby causing nuclear fusion; allows neutron energy generated by the nuclear fusion to be absorbed into liquid metal in which lithium and lead are dissolved; and transfers heat to water vapor or carbon dioxide through a heat exchanger so as to turn a turbine generator, thereby generating electricity. The plasma having the temperature of higher than or equal to 1 million °C is produced by heating, with a laser, the plasma discharged whenever the high-speed bullet is fired or the discharged plasma or heating, with a laser, a deuterium and tritium fuel capsule. In a tokamak or stellarator, the plasma can be maintained at higher than or equal to 1 million °C and compressed between the target and the high-speed bullet, thereby causing nuclear fusion. In order to increase the energy efficiency of fusion power generation, the plasma temperature, the collision speed between the target and the high-speed bullet, and the temperature at the fusion reaction can be further increased. The deuterium and tritium plasma having the temperature higher than or equal to 4 million °C can be made each time or maintained in a fusion reactor in order to create a fusion reaction. The target and the high-speed bullet each can be shot at the speed greater than or equal to 11 km per second to collide with each other at the speed greater than or equal to 22 km per second. When the target and the high-speed bullet collide with each other, the plasma having the temperature higher than or equal to 4 million °C can be compressed greater than or equal to 200 times between the target and the high-speed bullet to increase the plasma temperature to the temperature higher than or equal to 800 million °C, thereby creating a fusion reaction. The present invention can implement economical fusion power generation in a short time.
