  • Iran pushes ahead with nuke plans, despite seismic warnings

    Iranian officials have chosen to ignore the warnings of top scientists and continue with the construction of nuclear facilities near earthquake prone regions; according to an official with the International Atomic Energy Agency, in a top level meeting Iran’s leaders recently decided to move ahead with plans to construct nuclear facilities, despite Iranian scientists’ warnings that “data collected since the year 2000 shows the incontrovertible risks of establishing nuclear sites in the proximity of fault lines’ in Khuzestan as well as nineteen other Iranian provinces; Iran is one of the most seismically active countries in the world with major fault lines covering at least 90 percent of it

  • Japanese firms purchase radiation detection devices

    Universal Detection Technology (UNDT) recently announced that it has shipped radiation detection devices to companies across Japan including those in heavy industries, telecommunications, and electronics; according to UNDT, Japanese companies have been purchasing a range of devices including dosimeter systems to measure cumulative radiation exposure and advanced survey meters and surface monitors that detect the amount of contamination on surfaces

  • Glimmer of hope for Yucca Mountain nuclear waste repository project

    Over the last twenty-five years, the United States has spent around $15 billion on the Yucca Mountain Nuclear Waste Repository which was supposed to offer a solution to the growing nuclear waste problems at U.S. nuclear power plants; in what some charged was a political move by President Barack Obama to secure Nevada’s Democratic tilt, the administration defunded the project, and funding for work on the site was terminated altogether effective with the 2011 federal budget passed by Congress on 14 April 2011; some in Congress want the project to continue, and the House Appropriations Committee has added $35 million for the project in the 2012 energy spending bill; this is far cry from past appropriations for the project — typically around $400 million a year — and even one of the supporters, Representative Mark Simpson (R-Idaho) described it as symbolic gesture; there is also a case now being heard in federal court, in which the administration is charged with overstepping its bounds by cancelling the project without congressional permission

  • WikiLeaks: Japan brushes aside U.S. fears of nuke terrorism

    Diplomatic cables obtained by WikiLeaks reveal that U.S. officials were concerned about terrorist attacks at Japan’s nuclear facilities and the government’s seemingly lax security measures; one cable dated 26 February 2007, detailed a meeting where Japanese officials brushed aside U.S. concerns for physical security at one of the country’s nuclear facilities; additional cables sent from the U.S. Embassy in Tokyo to Washington D.C. reported that anti-terrorism drills held at nuclear facilities were unrealistic and overly “scripted”

  • Agreement reached on European Union stress tests

    Yesterday European Union officials reached an agreement on the parameters of nuclear stress tests and will soon begin conducting safety reviews at nuclear power plants; the tests will review the resiliency of 143 nuclear facilities in the face of natural disasters like earthquakes and tornadoes in addition to terrorist attacks; the move to conduct safety reviews was triggered by the ongoing nuclear crisis in Japan; events in Japan sparked anti-nuclear protests across Europe and leaders have called for a “comprehensive and transparent risk and safety assessment” at all atomic energy facilities in the European Union

  • Simple method of dealing with harmful radioactive iodine discovered

    Iodine radioisotopes are produced by fission of uranium fuel in a nuclear reactor; radioactive iodine is of concern because it is highly mobile in the environment and selective uptake by the thyroid gland can pose a significant cancer risk following long term exposure; furthermore, iodine-129, which is a type of radioactive iodine, has an extremely long half life of 15.7 million years, so is one of the most significant long term hazards faced by the population due to its emission during the geological disposal of nuclear waste; a University of Sheffield expert has discovered a novel way to immobilize radioactive forms of iodine using a microwave

  • Following Fukushima: how much radioactivity in the Oceans?

    A result of the loss of electricity at the Fukushima nuclear plant in Japan on 11 March, overheating led to significant releases of iodine, cesium, and other radioisotopes to the environment; Japanese officials recently raised the severity of the nuclear power plant incident to level 7, the highest level on the international scale and comparable only to the Chernobyl incident twenty-five years ago; the National Science Foundation awards rapid-response grants to establish ocean radionuclide levels from Fukushima

  • EU nearing agreement on nuclear stress tests

    The European Union could begin stress-testing its nuclear reactors as early as June 1; officials are nearing an agreement on the parameters for safety tests, but are still hammering out the last “two or three” issues; following the nuclear disaster at the Fukushima Daiichi nuclear plant in Japan, European energy officials as well as industry groups have been pushing the government to conduct stress tests on its nuclear facilities to determine how they will fare in various disaster scenarios; EU Energy Commissioner Guenther Oettinger has sought to include threats from terrorist attacks as well as cyber attacks, which has stalled stressed test negotiations

  • Researchers use gamma rays to detect hidden nuclear threats

    Researchers are currently exploring methods to use gamma rays to develop more powerful nuclear detection devices that can penetrate lead or other thick containers; scientists have created “MEGa-rays” by using fast-moving electrons to convert laser photons into the gamma part of the spectrum; these MEGa-rays are then tuned to a specific energy frequency so that they will only react with a certain type of material like uranium-235 which is used in nuclear fuel; scientists expect that the technology will be developed within the next several years

  • Smiths Detection launches new radiation detector; president steps down

    Last week Smiths Detection unveiled its new hand-held radiation detection device that is capable of more accurately identifying radiological and nuclear threats; the “RadSeeker” is designed to have a wide-range of applications to enable security officials and first responders to detect nuclear threats in addition to scanning cargo for nuclear material; the president of Smiths Group, Smiths Detection’s parent company, announced that he would step down; his decision is a result of weak sales at Smiths Detection

  • Japan attempts "cold shutdown" at reactor no. 1

    Officials at the Tokyo Electric Power Company (TEPCO) hope to bring reactor no. 1 at the beleaguered Fukushima Daiichi nuclear plant to a “cold shutdown” by the end of the week; plant operators will attempt to bring the temperature inside the reactor below the boiling point of water so that it will no longer produce radioactive steam; the building housing reactor no. 1 must be vented so that all the radioactive air that has accumulated is released allowing workers to approach the reactor; once inside workers will inject cold water into the reactor’s primary containment structure; injecting tons of water into a damaged containment unit that houses uranium makes some scientists uneasy

  • Recipe for radioactive materials helps in studies of nuclear waste and fuel storage pools

    Easy-to-follow recipes for radioactive compounds like those found in nuclear fuel storage pools, liquid waste containment areas, and other contaminated aqueous environments have been developed by researchers at Sandia National Laboratories; the trick to the recipes is choosing the right templates; these are atoms or molecules that direct the growth of compounds in much the way islands act as templates for coral reefs

  • Dynasil wins DHS award for radiation detection

    Dynasil Corporation’s research division, Radiation Monitoring Devices, Inc. (RMD), was recently named DHS’ small business winner for radiation and nuclear detection for 2011; the award is meant to honor small businesses that are excelling in innovative achievement and demonstrate a commitment to national security; RMD was recognized particularly for its development of two new radiation detection materials, strontium iodide and CLYC crystals; DHS is especially keen to develop these new radiation detection materials as the current industry standard, helium-3, is suffering from major shortages
