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.
For what I’m been reading online, that would be a waste of perfectly functioning nuclear material: check Nuclear reprocessing.
It a material remains radioactive means it still has energy in it, so the goal should be using it to the maximum. SMRs for example, might use reprocessed nuclear material at their core.
