Today that element, plutonium, is the main ingredient of weapons in the U.S. nuclear stockpile. Those weapons now are older - and the plutonium inside them has been aging longer - than any earlier stockpile weapons. So researchers at the National Nuclear Security Administration's Los Alamos National Laboratory are trying to hurry along the plutonium aging process to learn how long the metal will last and how that might affect the stockpile.
LOS ALAMOS, N.M., July 24, 2002 - Sometime after midnight on Feb. 25, 1941, in a cramped, third-floor laboratory at the University of California in Berkeley, Glenn Seaborg, Joseph Kennedy and Art Wahl for the first time isolated a new, man-made element, number 94, one that would change the world.
