Los Alamos restores U.S. ability to make nuclear weapons

Los Alamos National Laboratory has successfully made the first nuclear weapons pit in 14 years that meets specifications for use in the U.S. stockpile. The six-year effort at Los Alamos’ plutonium processing facility restores the nation’s ability to make nuclear weapons, a capability the United States lost when the Rocky Flats Plant near Boulder, Colo., shut down in June 1989.
