The lasers are aimed in pulses of 20 billionths of a second and 500 trillion watts-roughly 1,000 times U.S. The NIF possesses 192 laser beam lines, each more than 100 meters long. Under the Stockpile Stewardship and Management Program, created in the wake of the CTBT, the nation spends $15 billion a year to research and test nuclear material, some of it at the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory in California.Ĭonstruction on this massive fusion research facility, the size of a sports stadium, began in 1997 and took more than a decade to complete. efforts to ensure the readiness of its nuclear arsenal, however. signed the Comprehensive Nuclear-Test-Ban Treaty (CTBT), intended to prohibit “any nuclear weapon test explosion or any other nuclear explosion” anywhere in the world.
