First U.S. nuclear reactor built from scratch in decades enters commercial operation in Georgia::ATLANTA — A new reactor at a nuclear power plant in Georgia has entered commercial operation, becoming the first new American reactor built from scratch in decades.
If we can pull off hydrogen fusion without crazy radioactive isotopes I reckon we can go on for a little while without having to worry about running out of hydrogen in the solar system / galaxy
Instead we only have to worry about immediately running out of beryllium for breeding blankets just on the demo reactors.
