...Uranium -- which fell out of favor with US nuclear weaponeers in the 1950s -- may be the hip Fall fashion in certain New Mexican locales... Bob Peurifoy, a retired Sandia executive, favors dumping plutonium weapons in favor of low-tech uranium designs. Actually, Peurifoy prefers the current US arsenal, but Congress says the weapons labs should relax Cold War design requirements to build new warheads that are more reliable and require less toxic industrial processes... In that case, Peurifoy says, you can't do better than Uranium 235, which isn't nearly as expensive, toxic or fickle as plutonium.
Uranium fall down, go boom.
