But nuclear fusion is a reaction with hydrogen isotopes: deuterium and tritium as raw materials. As far as current technology is concerned, the only use of nuclear fusion is to make hydrogen bombs. The reason why it can't be used for power generation is that nuclear fusion has not developed to a controllable level, that is, once it starts, it can only react indefinitely until the raw materials are exhausted.
This reaction is dangerous to human activities, but the most important reason why it can't build a power plant is that the requirements for power plant interconnection are harsh.
For the grid connection of the generator set, it is necessary to ensure that the output voltage of the generator set is consistent with the power grid (the allowable deviation on the low voltage side is 10% and that on the high voltage side is 5%), and the frequency must be 60Hz (the allowable deviation is 0.5Hz). However, due to the uncontrollable nuclear fusion, the energy generated by it is unstable, which can't drive the turbine in the generator set to rotate at a uniform speed, so the voltage and frequency can't be stabilized within the required range.
The generator set that can't be connected to the grid is almost meaningless to the whole power system, so there can't be a nuclear fusion power station at present, which is what you call a hydrogen nuclear power station.
But nuclear fusion has great advantages for nuclear fission.
First of all, the fusion fuel of the same mass produces more energy than the fission fuel.
Second, the fuel of nuclear fusion and the products after the reaction are not radioactive. The explosion of hydrogen bomb is radioactive because nuclear fusion requires extremely high temperature to start the reaction, and the way to produce such high temperature is to detonate a small atomic bomb inside the hydrogen bomb. The raw material of the atomic bomb is uranium, so it is naturally radioactive. )
Third, the fuel for nuclear fusion is more widely distributed and abundant than that for nuclear fission.
