A hydrogen plasma converts hydrogen gas into neutrons:
Positron is an annihilate with electrons. A proton and electron to form a neutron plus gamma wave radiation and energy. A gas plasma is one way to facilitate the transformation of hydrogen gas into neutrons.
So we can use a hydrogen plasma as a source of neutron. So all the long half life isotopes produced by nuclear fission are transformed into short half life isotopes. Which fission into savour atoms.
We can transform the world's biggest store of plutonium, at Sellafield in Cumbria, into safe metal oxides. We don't need to store there used fission tubes for hundreds of thousands of years. Week in render the isotopes safe within six months.
We can use hydrogen plasma tubes as a way he to convert hydrogen into neutrons and heat. We use the heat to drive a steam process. This is heat with no carbon dioxide or fission waste.
Basically free power.
