    Two environmental organizations have asked the US Department of Energy to cancel experiments with plutonium at Lawrence Livermore National Laboratory’s (LLNL’s) National Ignition Facility (NIF). Representatives from the groups claim the experiments could contaminate the massive laser facility and possibly expose workers and the public to the toxic element. The Natural Resources Defense Council and Tri-Valley CAREs, in Livermore, California, charge that existing environmental impact statements do not include an adequate assessment of the environmental, safety, and proliferation aspects of zapping plutonium with beams from NIF’s 1.8-megajoule laser. The experiments are to be conducted in NIF’s massive 10-meter-diameter target chamber...
  • US takes back supercomputing crown with world's fastest computer

    A U.S. supercomputer has won back the crown in the never-ending battle for the world's most powerful supercomputer. Its victory is the latest milestone marking the steady climb of computing power all across the globe. The Top500 industry list gave its No. 1 ranking to the Sequoia supercomputer housed at Lawrence Livermore National Laboratory in California — a spot earned by Sequoia's ability to crunch 16.32 quadrillion calculations per second (16.32 petaflops/s). Such supercomputing power is used by the U.S. National Nuclear Security Administration to simulate nuclear weapons tests for older weapons that have been sitting in the U.S. arsenal....

    CALIFORNIA. Congresswoman Ellen Tauscher (D) was tapped this week to serve in the Obama Administration as US Undersecretary of State for Arms Control and International Security -- the Administration's top arms control negotiator. The centrist Tauscher -- who represents the CD-10 district which includes the Lawrence Livermore National Laboratory nuclear weapons/WMD research and development facility --- has been recognized as an expert on nuclear weapons issues during her seven-terms in Congress. "Keeping nuclear weapons out of the hands of terrorists, making sure other countries do not obtain them and, one day, I hope, ridding the world of these terrible weapons,...

    Australians Rejects Bulk Water Transfer in Favor of Desalination Research Last month the New York Times published an article about how the West is likely entering a prolonged period of water shortages. Similiar reports have recently been published in Australia detailing expected extended droughts over the next 50 years.The USA and Australia have responded to these reports in different ways.Several weeks ago I blogged about the current administration’s effort to push bulk water tranfers from Canada. This week Australia announced they were about to embark on a major desalination research project with the view of spending $250 million over seven...
  • Feds can activists' bid to run nuke lab (group wanted to study climate change, instead of nukes)

    GREEN LLC wanted move toward nonproliferation Federal nuclear weapons officials have rejected a bid by disarmament and renewable energy activists to manage Lawrence Livermore weapons design lab, saying the "green team" didn't fit federal plans. The team, calling itself GREEN LLC, was led by two weapons-lab watchdog groups, Livermore-based Tri-Valley CAREs and Nuclear Watch of New Mexico, who never really expected to run the sprawling bomb lab. But they were offended that the National Nuclear Security Administration said the team's proposal ran afoul of federal law and "did not demonstrate an understanding of the requirements of the solicitation where it...
  • Artist corrects her infamous spelling mistakes in Livermore mural

    “What’s in a name?” Shakespere asked. Make that “Shakespeare.” Miami artist Maria Alquilar, much maligned for 11 misspellings that popped up in the educational mural she designed for the Livermore public library last year, spent today under the hot sun correcting her mistakes. In addition to fixing the bard’s name, she changed “Eistein” to “Einstein,” “Gaugan” to “Gauguin” and more. But Alquilar, who at first claimed artistic license and said she wasn’t going to return to fix the faux pas because people were being too mean about it, was giving no media interviews as she worked under a broad-brimmed straw...
  • Scientists conduct subcritical nuclear experiment in Nevada

    Associated Press | September 19, 2003
    LAS VEGAS (AP) - Government scientists conducted an underground nuclear materials experiment Friday at the Nevada Test Site, the National Nuclear Security Administration said. The subcritical experiment, dubbed Piano, involved detonating high explosives to chart the behavior of plutonium in a non-nuclear explosion. It did not trigger a self-sustaining nuclear reaction, NNSA spokesman Kevin Rohrer said. Scientists from the Lawrence Livermore National Laboratory in California completed the test at 1:44 p.m. in a cavern 960 feet below ground, Rohrer said. No abnormalities and no surface damage were reported at the vast site, about 85 miles northwest of Las Vegas....

    LIVERMORE, Calif. -- The National Ignition Facility (NIF) at Lawrence Livermore National Laboratory recently produced 10,400 Joules or 10.4 kiloJoules (kJ) of ultraviolet laser light in a single laser beamline, setting a world record for laser performance.In recent weeks NIF laser scientists also have used the first four NIF beamlines to set records for infrared and green single beam laser energies with 21 kJ and 11 kJ of energy delivered, respectively. NIF researchers focused this light into a special diagnostic system designed to provide precise measurements of laser beam quality and performance at these different frequencies. The NIF laser system...

    The compromised system is known as the Nuclear Weapons Information Program (NWIP). It was mentioned publicly in a 1995 LLNL Website press release that described it as a series of upgrades to the lab's computer systems to make it easier for scientists to coordinate and share information. Insight is told that this was like revealing that there's a stealth fighter but concealing how it is built and what secrets are aboard. quot;This is one of the most classified projects on Earth given what its mission is,quot; says a well-placed source. In essence, say Insight sources, it is the single repository...
