• States challenge federal policy on nuclear waste storage

    The search for a permanent solution to the storage of nuclear waste continues as three states sued the Nuclear Regulatory Commission (NRC) last week over its new policy on spent fuel; in December NRC issued a new policy stating that nuclear waste could be safely stored at a power plant for sixty years after a reactor went out of service; the issue of nuclear storage has become increasingly contentious after the Obama administration ruled out the use of a Department of Energy storage site in Nevada in 2009; nuclear plants have been forced to turn temporary on-site storage into long-term facilities as no permanent site has been built; the Obama administration launched a commission to find alternatives for the permanent nuclear storage site in Nevada that it cancelled

  • No, a Boy Scout cannot build a backyard nuclear reactor

    Dirty bombs are easy to build and only require strapping explosives to radioactive material; in counter-terrorism circles there is a myth that in 1995 a Boy Scout was able to assemble enough radioactive materials to build a nuclear reactor in his backyard in Michigan by gathering all of his materials from common household items; he dismantled lanterns to obtain Thorium, smoke detectors for Americium, and old clock dials for Radium; analysts say that it would take material from roughly two million smoke detectors to build a dirty bomb that would cause any damage

  • Free radiation monitors handed out in South Carolina

    Ionizing radiation, the most energetic form, is capable of removing electrons from atoms and damaging the DNA within living cells; widespread panic caused by a dirty bomb, small nuclear device, or nuclear fallout would leave people questioning whether or not they were exposed to a lethal dose of ionizing radiation; the RadSticker is an inexpensive citizen’s dosimeter which could minimize panic in the event of a radiological incident

  • Japan and U.S. agree on nuclear counterterrorism road map

    Japan and the United States are preparing a “road map” for cooperative efforts to prevent atomic site workers from stealing potential ingredients for an act of nuclear terrorism; the plan would also address the development of “security-by-design concepts” for facilities such as nuclear energy stations and atomic fuel processing sites

  • Medical isotopes could be made without a nuclear reactor

    Canadian researchers are racing to perfect a safe, clean, inexpensive, and reliable method for making isotopes used in medical-imaging and diagnostic procedures — a method which would not require a nuclear reactor and could, therefore, eliminate future shortages of technetium-99m, the most widely used medical isotope today; what is more, the new method generates virtually no radioactive waste materials that must be stored indefinitely

  • Port radiation detectors not properly tested

    A new report by the National Academy of Sciences says that DHS officials responsible for defending against radiological and nuclear terror attacks did not properly test high-tech radiation detectors for use at the nation’s ports of entry

  • Cement prison for old radioactive waste

    The cold war may be over, but its radioactive legacy is not; between 1950 and 1990, nuclear weapons materials production and processing at several federal facilities generated billions of gallons of water contaminated with radioactive byproducts; researchers at Idaho National Laboratory test an inexpensive method to sequester strontium-90 where it lies. The researchers can coax underground microbes to form calcite, a white mineral form of calcium carbonate and the main ingredient in cement. Calcite should be able to trap strontium-90 until long after it has decayed into harmless zirconium

  • New technology speeds cleanup of nuclear contaminated sites

    Hundreds of millions of dollars are spent on cleanup of some major sites contaminated by radioactivity, primarily from the historic production of nuclear weapons during and after the Second World War; Oregon State University researchers have invented a new type of radiation detection and measurement device that will be particularly useful for cleanup of sites with radioactive contamination, making the process faster, more accurate and less expensive

  • WikiLeaks: Yemen radioactive stocks "easy al-Qaeda target"

    Yemeni official told U.S. diplomats that the lone sentry standing watch at Yemen’s national atomic energy commission (NAEC) storage facility had been removed from his post, and that the facility’s only closed circuit TV security camera had broken down six months previously and was never fixed; “Very little now stands between the bad guys and Yemen’s nuclear material,” the official warned, in a cable dated 9 January this year sent from the Sana’a embassy to the CIA, the FBI, and the department of homeland security; when told of the Yemeni nuclear storage problem, Matthew Bunn, a Harvard University nuclear terrorism expert, said: “Holy cow. That’s a big source. If dispersed by terrorists it could make a very nasty dirty bomb capable of contaminating a wide area”

  • Medical isotopes no longer require weapons-grade uranium

    Highly enriched uranium (HEU) is used in nuclear weapons, but it is also used to make the radioisotopes that are injected in tiny quantities into people to diagnose and treat disease; indeed, making medical isotopes is a time-honored excuse for enriching uranium, if you want to build nuclear weapons but do not want to admit you are doing so (this is the cover Iran is using for its bomb-oriented enrichment program); South Africa’s Pelindaba reactor is now producing medical treatment-oriented molybdenum-99 (Mo-99) made from low-enriched uranium

  • Spotting illicit nuclear activity from a distance

    French scientists unveil a plan to place antineutrino detectors off the coast of rogue nations suspected of operating clandestine nuclear reactors; their idea is to turn a supertanker into an antineutrino detector by kitting it out with the necessary photon detectors and filling it with 10^34 protons in the form of 138,000 tons of linearalkylbenzene (C13 H30); the plan is to sink the tanker in up to four kilometers of water off the coast of a rogue state, and the supertanker would then watch for the telltale signs of undeclared antineutrino activity

  • Nuclear DUI: DOE IG finds cause for concern

    There are about 600 OST (Office of Secure Transportation) agents — that is, drivers who have permits to haul nuclear weapons, weapons components, and special nuclear material (SNM) around the country; the Department of Energy inspector general investigated reports that some of these drivers are drunk on the job; a new report found 16 incident, of which 2 were of “particular concern”

  • U.S., Kazakhstan complete secret transfer of Soviet-era nuclear materials

    In the largest such operation ever mounted, U.S. and Kazakh officials transferred 11 tons of highly enriched uranium and 3 tons of plutonium some 1,890 miles by rail and road across the Central Asian country; the nuclear material, which could have been used to make more than 770 bombs, was moved from a facility feared vulnerable to terrorist attack to a new high-security facility

  • New nuclear detection method does not use helium

    Current nuclear detection technology uses helium 3, which was a by-product of the U.S. earlier nuclear weapons programs and which is in increasingly short supply; Dynasil’s new “dual mode” detectors are designed to work without helium 3 and can replace two separate nuclear detector systems for gamma radiation and for the neutrons from nuclear materials

  • DHS gives New York $18 million for radiation detection system

    DHS will hand New York $18.5 million today to keep the city’s prototype dirty-bomb detection system running; the nuclear detection operation is run out of an operations center in the city, featuring more than 4,500 pieces of radiation detection equipment, many equipped with GPS locators
