The Secretary’s visit provided him the opportunity to see firsthand how Los Alamos National Laboratory uses innovative science and technology to make our nation and the world a safer place.’ The pit casting area is where molten plutonium is shaped into a pit, the plutonium core of a nuclear weapon.
