From its inception in the 1940's, nuclear power as conceived by the United States had a closed fuel cycle. Uranium would be mined and milled, enriched in its fissionable isotope U-235 from the 0.7% found in nature, manufactured into fuel and burned in reactors to generate electricity. As it burned, some of the uranium would be converted to plutonium. Then the spent fuel would be removed and shipped to a central plant where it would be dissolved and reprocessed chemically. The unburned uranium and plutonium would be separated and could be recycled in new fuel. The radioactive fission products would be buried as waste.

Charles Till led a team of thousands of scientists, engineers and technicians in the 1980s up to 1994 in the successful development of one of the world's greatest technologies for producing electricity only to have the project stopped by President Clinton and behind the scenes anti-nuclear activists, non-profits, industry and the government. This is surely one of the greatest reversals ever in modern civilisation. China, Russia and other countries are NOT following the example set by President Clinton and they will be far better for it.

Charles Till and Yoon Chang describe the progress of recycling metallic spent nuclear fuel in the Integral Fast Reactor Program at Argonne National Laboratory. This is a key step to providing plentiful energy for the world for a very long time.

Professor Emeritus of Physics at the University of Pittsburgh. Professor Cohen was a staunch opponent of the so-called Linear no-threshold model (LNT) which postulates there exists no safe threshold for radiation exposure: We conclude that all the world's energy requirements for the remaining existence of life on Earth could be provided by breeder reactors without the cost of electricity rising by as much as 1% due to fuel costs. This is consistent with the definition of a "renewable" energy source.
