• Detecting radioactive material in nuclear waste water

    As the Fukushima crisis continues to remind the world of the potential dangers of nuclear disposal and unforeseen accidents, scientists are reporting progress toward a new way to detect the radioactive materials uranium and plutonium in waste water.

  • Security agencies concerned about plastic guns

    The Undetectable firearms Act of 1988, which makes it illegal to manufacture, import, sell, ship, deliver, process, transfer, or receive a firearm which is not detectable by walk-through metal detection, is set to expire on 9 December 2013. If Congress fails to reauthorize the law, plastic guns will no longer require metal components which are detectable by metal detectors. “When these 3D firearms are manufactured, some of the weapons can defeat normal detection such as metal detectors, wands, and it could present a problem to public safety in a venue such as an airport, an arena, a courthouse,” says ATF assistant director Richard Marianos.

  • GAO says TSA’s costly behavioral detection program falls short

    The Government Accountability Office(GAO) said last week that DHS may have wasted $1 billion on the Transportation Security Administration’s (TSA) Screening of Passengers by Observation Techniques (SPOT) program. SPOT aims to spot terrorists by detecting “anomalous” or suspicious behavior. The anomalous behavior – perspiration, fidgeting, restlessness – is supposed to be the result of high levels of stress, fear, or deception. Individuals who exhibit anomalous behavior are subject to additional security screening.

  • New drone to monitor radiation following nuclear disasters

    Researchers have unveiled a large semi-autonomous drone called the ARM system which could be used to provide visual and thermal monitoring of radiation after a release of nuclear material. The system was developed in response to requirements for radiation monitoring in event of the release of radioactive materials.

  • DOE to resume transient testing of nuclear fuels and materials

    Transient testing of nuclear fuel involves placing fuel or material into the core of a nuclear reactor and subjecting it to short bursts of intense, high-power radiation in order to analyze the effects of the radiation. The Idaho National Laboratory (INL) Transient Reactor Test Facility began operating on 23 February 1959 and was a principal reactor safety testing facility in the United States for thirty-five years. The U.S. Department of Energy invites the public to read and comment on a draft environmental assessment it has prepared for a proposal to resume transient testing of nuclear fuels and materials.

  • Sunlight-activated nanogrid breaks down pollutants in water

    Oil spills do untold damage to the environment — to the waters they pollute and to marine and other wildlife. The Deepwater Horizon spill in the Gulf of Mexico in 2010, for example, the largest accidental marine oil spill in the history of the petroleum industry, flowed unabated for three months. Typically, such oil spills are extraordinarily difficult to clean up. Soon, however, the process may become infinitely easier and ecologically friendly, the result of a new invention — “nanogrid” — a large net consisting of metal grids made of a copper tungsten oxide, that, when activated by sunlight, can break down oil from a spill, leaving only biodegradable compounds behind.

  • Nuclear experts: world is safer, but risks remain

    Speaking at a two-day short course on Nuclear Weapon Issues in the Twenty-First Century earlier this month, leading nuclear weapons scientists and policymakers said that despite some troubling areas, the world is a safer place than in past decades, and they expressed cautious optimism it is continuing in that direction. They warned, however, that despite this progress, crises involving nuclear weapons can still spiral out of control.

  • Reducing volume of nuclear waste by 90 percent possible

    Engineers have developed a way significantly to reduce the volume of some higher activity wastes, which will reduce the cost of interim storage and final disposal. The researchers have shown that mixing plutonium-contaminated waste with blast furnace slag and turning it into glass reduces its volume by 85-95 percent. It also effectively locks in the radioactive plutonium, creating a stable end product.

  • The irreducible elements of a Freeze Plus interim agreement with Iran

    Iran and the P5+1 are set to resume talks on Iran’s nuclear program tomorrow, Thursday, 7 November in Geneva.The Institute for Science and International Security (ISIS) has developed a list of what it calls “irreducible elements” which a negotiated interim agreement should aim to achieve. These four elements are: Stopping the advance of Iran’s centrifuge and Arak reactor programs; extending breakout times; capping the Iranian centrifuge program and ensuring that it will not expand beyond this cap (in terms of enrichment output) during the next 5-15 years; and increasing the chance of finding a secret centrifuge or plutonium separation plant.

  • China buys Implant Sciences explosives detectors to protect nuclear power plants

    Implant Sciences has sold multiple units of its QS-H150 handheld explosives trace detectors to a customer in China, who will be deploy them across several locations for the purpose of protecting nuclear power plants in multi-layered security environments.

  • Pyreos, ultra‐low power consumption IR sensor specialist, secures $4 million investment

    Edinburgh, Scotland-based Pyreos Limited, a specialist in ultra‐low power consumption infrared sensor technology, the other day announced plans for international expansion after securing a further funding round of $4 million. It is possible to use Pyreos sensor arrays in many applications, among them border security, where they can identify human movement at distances of several kilometers.

  • Detecting threats in a crowd

    Around a military camp situated close to a built-up area there are always people moving about. Scientists at FOI, the Swedish Defense Research Agency, have created a multi-sensor system designed to be able to detect threats by identifying unusual patterns of movement involving individuals or groups.

  • Quick ID for water pathogens

    New research purports to help people stay healthy by developing a real-time water bug testing that could precisely identify the culprits responsible for waterborne disease.

  • Where should U.S. radioactive waste be buried?

    In the United States, about 70,000 metric tons of spent commercial nuclear fuel are located at more than seventy sites in thirty-five states. Shales and other clay-rich (argillaceous) rocks have never been seriously considered for holding America’s spent nuclear fuel, but it is different overseas. France, Switzerland, and Belgium are planning to put waste in tunnels mined out of shale formations, and Canada, Japan, and the United Kingdom are evaluating the idea.

  • Russia to build floating nuclear power plants

    Global warming is opening the Arctic Ocean to shipping – and causing the rapid melting of Arctic ice. Russia says that ship-based nuclear power plants would allow it to provide power to remote cities in Siberia, and provide power to oil and gas drilling operations in the Arctic (about 30 percent of the world’s unclaimed natural gas is in the Arctic, and about, 60 percent of that unclaimed natural gas is in the Russian Arctic). Experts worry about the ability of ship-based nuclear reactor to withstand extreme weather events, or terrorist attacks. The U.S. Army deployed its own floating nuclear reactor – the Sturgis – in the Panama Canal Zone from 1968 to 1976.
