Burn-Out. Plutonium is fissionable and a fine nuclear fuel, but the first reactors did not produce enough of it to replace the U-235 consumed. So their nuclear fuel gradually "burned out," leaving U-238 as a sort of ash. Thus, the reactors of the early atomic age could utilize only a very small part of the uranium fed into them...
...breeders, or converters, will lessen the waste, presumably by causing more neutrons to be absorbed byU-238. If the amount of plutonium or other nuclear fuel thus produced is larger than the U-235 consumed, the pile could continue in operation for a very long time. First the original U-235 would be consumed, yielding energy and plutonium made out of 11-238. Then some of the plutonium would fission, yielding energy and creating more atomic fuel. Theoretically, the process might continue until all the 11-238 is consumed. Natural uranium could yield something like 140 times as much energy...
Loathe Labels. Like any artist worth the name, Stuempfig loathes labels. He accepts the label "romantic" only because he believes that "all good painters are romantic painters. You have to have a certain romantic approach to life or you wouldn't be a painter in the first place. I can't define the word; to me it applies even to Thomas Eakins and Velasquez...
