@RichStein @bojacobs @nellgreenfieldboyce Back in the day, they dreamed of an endless fuel cycle.
Recycling the uranium and Plutonium in nuclear reprocessing plants. Disposing only the high active waste and even this waste was planned to be processed to radiologic sources for medical and industrial use. But it has proven to be impossible without a huge ecological impact and release of radionuclides.
This dream lived till the '80 of the last century. And there are still people think of this.
