  • LANL’s Melton to head W. Va. Capitol agency

    CHARLESTON, W.Va. (AP) — An official at the Los Alamos National Laboratory will oversee the West Virginia Capitol and other state buildings.
    Administration Secretary Ross Taylor announced Gregory Melton as the new director of the General Services Division on Monday. Melton starts April 1.
    A West Virginia native, Melton has been a maintenance manager and group leader at Los Alamos. The New Mexico complex is 36 square miles with more than 1,200 buildings and 8 million square feet of facility space.
    General Services oversees the state Capitol building and its campus as well as other state government buildings around West Virginia.
    Melton is a West Virginia University graduate and a former U.S. Air Force officer. He succeeds David Oliverio, who helped oversee a major turnaround at General Services before his departure earlier this month.

  • LANL sleuth on trail of Martian mystery

    When it comes to examining the surface of rocks on Mars with a high-powered laser, five is a magic number for Los Alamos National Laboratory postdoctoral researcher Nina Lanza.
    During a poster session today at the 44th Annual Lunar and Planetary Science Conference at The Woodlands, Texas, Lanza described how the laser-shooting ChemCam instrument aboard the Curiosity rover currently searching the surface of Mars for signs of habitability has shown what appears to be a common feature on the surface of some very different Martian rocks during Curiosity’s first 90 days on the Red Planet.
    But exactly what that common feature is remains an intriguing mystery — and one that Lanza intends to solve.
    The ChemCam instrument uses an extremely powerful laser to vaporize a pinpoint of rock surface. The instrument then reads the chemical composition of the vaporized sample with a spectrometer. The highly accurate laser can fire multiple pulses in the same spot, providing scientists with an opportunity to gently interrogate a rock sample, even up to a millimeter in depth. Many rocks are zapped 30 to 50 times in a single location, and one rock was zapped 600 times.
    Members of the ChemCam team generally discard results from the first five laser blasts because of a belief that after the first five blasts.

  • Flyovers find no increase in radioactivity

    Measurements from two recent aerial flyovers to determine the presence of background and man-made radioactivity brought good news for Los Alamos County and Los Alamos National Laboratory.

    The radiological surveys, conducted in August 2011 and June 2012, found that radioisotopes and their associated exposure rates are consistent with those expected from normal background radiation.

    “These surveys were well worth the effort,” said Juan Griego, acting manager for the Los Alamos Field Office. “The results are good news and the information will benefit the lab and the community for years to come as we work toward cleanup and sustainability.”

    The 2011 survey focused on the White Rock community and Los Alamos National Laboratory, over which a specially equipped helicopter from Nevada’s Remote Sensing Lab flew approximately 150-feet above ground to gather radiological data.

    The 2012 survey concentrated on the Los Alamos town site. That survey gathered data from 300 feet above the ground in order to limit noise to residents and animals, specifically the horses on North Mesa. Measurements taken from the flyover are equivalent to measurements taken from one meter above ground.

  • NMED takes action on WIPP

    The New Mexico Environment Department took final administrative action on a Class 2 permit modification request to the Waste Isolation Pilot Plant Hazardous Waste Facility Permit Wednesday.
    NMED has approved the modification with changes regarding the mandatory testing of all mixed waste containers. This permit modification is not related to the recent news regarding an anticipated permit modification request for the Hanford tank waste.
    The Department of Energy Carlsbad Field Office and Nuclear Waste Partnership LLC (the permittees) submitted a Class 2 PMR to the NMED on Dec. 12, seeking to revise the waste analysis plan waste characterization methods.
    NMED did a review of the proposed changes on waste analysis plan waste characterization methods. This included the review of comments submitted during a 60-day public comment period, which began Dec. 19 and ended Feb. 18.

  • Exercise planned Thursday at LANL

    Los Alamos National Laboratory will conduct an emergency-preparedness exercise Thursday. It is only an exercise. The lab routinely conducts emergency exercises to test the preparedness of emergency response and other LANL personnel who would respond to an actual emergency.
    The majority of the exercise is on LANL property and shouldn’t affect the public. Signs will be placed outside the Los Alamos Medical Center alerting the public that an exercise is under way. LANL employees in affected facilities will be notified before the exercise begins and when it is completed. Los Alamos County also has been notified of the emergency exercise.
    For more information, call Steve Sandoval at 665-9206.

  • Physicists say they have found a Higgs boson

    The search is all but over for a subatomic particle that is a crucial building block of the universe.

    Physicists announced Thursday they believe they have discovered the subatomic particle predicted nearly a half-century ago, which will go a long way toward explaining what gives electrons and all matter in the universe size and shape.

    The elusive particle, called a Higgs boson, was predicted in 1964 to help fill in our understanding of the creation of the universe, which many theorize occurred in a massive explosion known as the Big Bang. The particle was named for Peter Higgs, one of the physicists who proposed its existence, but it later became popularly known as the “God particle.”

    One Los Alamos National Laboratory scientist could not have been happier.

    Michael Graesser has done extensive research on the Higgs boson particle and gave a series of lecture on the topic late last year.

    Back in October, Graesser said, “A new particle was discovered last summer at the Large Hadron Collider at CERN in Switzerland. The Higgs boson gives mass to quarks and the electron but we don’t know yet if this new particle is the Higgs boson.”

    But now, the rest of the science world knows the new particle is the Higgs boson.

  • Manhattan Project bill gets another shot

     Congress is once again looking at the possibility of establishing a Manhattan Project National Historical Park. 

    On March 7, Senators Maria Cantwell (D-Wash.) and Lamar Alexander (R-Tenn.) introduced the legislation, S. 507, which would create a national park with units in Los Alamos,  Oak Ridge, Tenn. and Hanford, Wash. Senators Martin Heinrich (D-N.M.), Tom Udall (D-N.M.) and Patty Murray (D-Wash.) co-sponsored the bill.

    “As Americans, we have a special obligation to preserve and protect our heritage, and the Manhattan Project National Historical Park will ensure that all Americans learn about the significance of the Manhattan Project and how it continues to shape our history,” said Senator Alexander. 

    Sen. Ron Wyden (D-Ore.), the Chairman of the Senate Committee on Energy and Natural Resources, pledged to support the park during a visit to the Hanford B Reactor.

  • DOE letter raises questions

    The Department of Energy’s Daniel Poneman recently sent Gov. Susana Martinez a letter regarding how the state would be affected by the sequestration order.

    Was it just a bunch of hype? Or are their dire consequences ahead?

    It’s hard to tell.

    Poneman estimated that reductions to contractors are estimated at $67 million and contractors may be forced to furlough or lay off more than 8,200 employees in New Mexico.

    As far as Los Alamos National Laboratory is concerned, Poneman wrote that DOE would decrease funding to the lab by approximately $61 million. He also said that could result in the furlough or layoffs of another 8,200 employees.

    Poneman also said there would be decreased funding to the Waste Isolation Pilot Plant in Carlsbad, which would decrease the number of radioactive waste shipments.

    The Governor’s office, meanwhile, responded to the DOE letter Saturday.

    “Governor (Susana) Martinez believes we, as New Mexicans, must put aside partisan differences and fight to protect ourselves from indiscriminate federal cuts,” the statement said.

  • Lab promotes Sarrao

    Los Alamos National Laboratory has named John Sarrao as the new Associate Director for Theory, Simulation and Computation. Sarrao joined the laboratory in 1997 as a technical staff member in experimental condensed matter physics.
    He has held a variety of management positions including Materials Physics and Applications division leader. His most current position was LANL’s DOE Office of Science program director and director of the Material Radiation Interactions in Extremes (MaRIE) program.
    The ADTSC is part of the Principal Associate Director for Science, Technology and Engineering organization at Los Alamos. Sarrao will have responsibility for the Advanced Computing Solutions office and Computer, Computational and Statistical Sciences, High Performance Computing and Theoretical divisions.
    “John is a world-class scientist with a distinguished record of discoveries and international recognition,” said Laboratory Director Charlie McMillan. “His track record as a research scientist and his experience leading and managing a large, complex multi-disciplinary technical organization give me full confidence in his abilities.”

  • Lab adds another facility to process nuclear waste

    Los Alamos National Laboratory has brought a third waste repackaging facility online to increase its capability to process nuclear waste for permanent disposal.

    The “375 box line facility” enables Los Alamos to repackage transuranic waste stored in large boxes.

    Built inside a dome once used to house containers of waste at the laboratory, the facility is the largest Perma-Con structure ever constructed. A Perma-Con is a modular structure typically used for radiological or hazardous containment.

    Contaminated items such as equipment and protective clothing, used during past operations at Los Alamos, are removed from their containers inside the structure and then are repackaged for shipment to licensed, permanent disposal facilities.

    The record-setting structure is 110-feet long by 48-feet wide.

    “We needed to build a structure big enough to accommodate these waste boxes, some of which are 40 feet long,” said Jeff Mousseau, associate director of environmental programs at LANL. “These are the largest, most contaminated boxes of waste at Los Alamos, and this facility will give us the capability to repackage them safely.”

    The Perma-Con structure was provided by Radiation Protection Systems, Inc.
