Californians anxious about safety of nuclear reactors
The parallels between Japan and California are sobering: As in Japan, California’s two plants — Diablo Canyon near San Luis Obispo and San Onofre in Southern California — sit in active earthquake zones; like Japan’s, both rest beside the ocean and were built more than a quarter-century ago; perhaps most troubling, the San Onofre plant straddles two counties in Southern California with a combined population of 6 million people

Official: U.S. safe from Japanese radiation
U.S nuclear officials said that there was very little chance that harmful levels of radiation from Japan’s nuclear reactors would reach Hawaii or the west coast of the United States; the head of the Nuclear Regulatory Commission (NRC) also said nuclear plants in the United States were designed to withstand natural disasters like earthquakes and tsunamis; readings from radiation sensors placed on the west coast have not detected any increases in radiation levels and experts do not expect any increases; Japanese utilities have flooded two nuclear reactors with sea water in a desperate attempt to cool them down and prevent a meltdown; the NRC has dispatched two nuclear experts to Japan to assist with efforts to keep three damaged reactors from melting down

Future of U.S. nuclear plans uncertain after Japanese nuclear crisis
As Japan continues its struggle to control its nuclear reactors, the future of the U.S. nuclear industry has become increasingly uncertain; nuclear power had emerged as the bipartisan solution to easing America’s dependency on oil; in February 2010, President Obama announced $8.3 billion in loan guarantees to energy companies to build the first new nuclear power plants in the United States in almost thirty years; some lawmakers have called for a moratorium and stricter safety regulations, while others are urging for a more measured response; Energy Secretary Stephen Chu and Gregory B. Jaczko, the chairman of the Nuclear Regulatory Commission, will testify before the House Energy and Commerce committee on Wednesday

New .gov threat detection software nearing completion
DHS is currently in the final stages of implementing Einstein 2, its new cybersecurity threat detection system, across all federal networks; Einstein 2 is designed to provide the government with intrusion detection tools on its networks; installation is expected to be completed this year; DHS is also in the midst of testing Einstein 3 and hopes to begin installation of that system within the year; the Einstein system is part of a total suite of technological solutions designed to secure the .gov domain from cyber threats; these tools are being developed in conjunction with the Department of Defense

Helium-3 shortage endangers nuclear detection capabilities
Demand for radiation detectors has surged as a result of increased efforts to stop nuclear proliferation and terrorism, but production of helium-3, a critical element in nuclear detection technology, has not kept pace and existing stockpiles are quickly dwindling; in 2010 demand for helium-3 was projected to be 76,000 liters per year; the United States only produces 8,000 liters of helum-3 a year; last year the U.S. stockpile of helium-3 was at less than 48,000 liters; alternatives are currently in the early stages of development and researchers have found several promising leads; when an alternative is found, current radiation detection equipment will have to be replaced with the new technology

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
