If you were a terrorist looking for weapons-grade nuclear material in America, the Lawrence Livermore National Laboratory might be a good place to start. At the core of the nuclear-weapons research facility about an hour’s drive from San Francisco stands the “Superblock,” a collection of buildings surrounded by multi-story steel-mesh fencing, a no-man’s-land, electronic security gear, armed guards and cables to prevent a helicopter landing on the roof. These defenses are in place largely to protect Building 332, a repository for roughly 2,000 pounds of deadly plutonium and volatile, weapons-grade uranium — enough fissile material to build at least 300 nuclear weapons. But a recent simulated terror attack tested those defenses, and sources tell TIME that the results were not reassuring.
One night several weeks ago, according to TIME’s sources, a commando team posing as terrorists attacked and penetrated the lab, quickly overpowering its defenses to reach its “objective” — a mock payload of fissile material. The exercise highlighted a number of serious security shortcomings at Livermore, sources say, including the failure of a hydraulic system essential to operating an extremely lethal Gatling gun that protects the facility. Experts contacted by TIME — including congressional staff from both parties informed of the episode, and experts personally familiar with safeguards at Livermore — all said that the test amounts to an embarrassment to those responsible for securing the nation’s nuclear facilities, and that it required immediate steps to correct what some called the most dangerous security weaknesses ever found at the lab.
