Many Santa Feans understand that Los Alamos National Laboratory, the most lavishly funded nuclear weapons facility in the world, has embarked on a new mission: making plutonium warhead cores (“pits”) on an industrial scale, to involve 4,000 full-time personnel and 24/7 operations.

It’s among the dirtiest and most dangerous missions in the nuclear weapons complex, not seen at LANL since the 1940s. It’s centered in an old facility built for research and development, now to be driven far beyond its original capacity.

LANL predicts it will spend $18 billion to start up production over this decade. In constant dollars, this is 15-fold what the Manhattan Project spent in New Mexico — indeed it dwarfs the cost of every other project in New Mexico history.
