Thomas Cochran has been working with the Natural Resources Defense Council since the 1970s to impede the use of nuclear power, particularly the kind that uses most of the potential energy and produces the lease amount of radioactive waste: The closed fast-reactor fuel cycle for transmutation of waste is: uneconomic, unreliable, unsafeguardable, unsafe, unworkable. If this is not bad enough, several costly reprocessing plants would need to be built for each geologic repository avoided and there is no evidence that the releases from the closed fuel cycle will have fewer health impacts than from geologic repositories.
Michel Gay, l'Association des écologistes pour le nucléaire (AEPN): L'énergie nucléaire continuera a jouer un role significatif dans le futur bouquet énergétique mondial, mais une meilleure valorisation de l'uranium sera nécessaire dans de nouveaux réacteurs pour poursuivre au-dela de ce ciécle.
Ken Kok is a nuclear engineer and leading member of the American Society of Mechanical Engineers advocating for advanced nuclear power technology with spent fuel recycling. Used nuclear fuel and depleted uranium are already mined and milled resources that can power all of America's electrical energy needs at 1994 levels for over 700 years. This is more valuable than fossil fuels and would not require mining for these needs. Combined with fossil fuels, and uranium and thorium still in the ground, the United States and the rest of the world potentially have enough energy to improve the lives of people everywhere for as far as we think civilization will last.
