Closing the fuel cycle involves recycling the nuclear waste as new fuel. Since the main component of nuclear waste is Uranium-238 (which can be transmuted to Plutonium, especially with advanced breeder reactors), we can get more energy out of the waste than in a once-through cycle (see factoid 2 to see how much). read more
Nuclear waste is recyclable. Once reactor fuel (uranium or thorium) is used in a reactor, it can be treated and put into another reactor as fuel. In fact, typical reactors only extract a few percent of the energy in their fuel. read more
Nuclear power may produce no green house gases, but the nuclear waste it leaves behind, remaining radioactive for as long as 100.000 years, does possess a terrible problem for both people and the environment. read more
