• Students of Nuclear Security Have a Problem. Here’s How to Help Them.

    Radioactive materials are attractive targets to thieves and other bad actors. These are rare finds, valuable on the black market and relatively easy to weaponize. New security professionals rarely learn practical skills for protecting these targets until they are on the job at nuclear power plants, research reactors, processing plants and other nuclear facilities.

  • Study Identifies Reasons for Soaring Nuclear Plant Cost Overruns in the U.S.

    Analysis points to ways engineering strategies could be reimagined to minimize delays and other unanticipated expenses. Many analysts believe nuclear power will play an essential part in reducing global emissions of greenhouse gases, and finding ways to curb these rising costs could be an important step toward encouraging the construction of new plants.

  • Putting Nuclear Reactors in Space

    A new agreement hopes to speed along a nuclear reactor technology that could be used to fuel deep-space exploration and possibly power human habitats on the Moon or Mars.

  • Mini Nuclear Reactor to Solve the E-Truck Recharging Dilemma

    Electric semitrucks sound like a great idea, leading to cleaner, carbon-free skies. But the largest cross-country 18-wheel truck needs five to 10 times more electricity than an electric car to recharge its battery. And these trucks often need to recharge far from high-power transmission lines. Where will that electricity come from? Engineers will tell you the answer is clear — microreactors.

  • U.K. Nuclear Power: The Next Huawei?

    London’s relations with China — hailed as entering a “golden era” only four years ago — have deteriorated badly over the coronavirus crisis and the Hong Kong issue, hitting a nadir when the U.K. finally bowed to U.S. pressure to ditch Huawei’s involvement in its new-generation internet (5G) rollout. China warned the U.K. it would face “consequences if it chooses to be a hostile partner” after London announced its Huawei’s decision. Nuclear power, once a key part of the U.K. energy plans, faces rising costs, cheaper renewables, and domestic opposition – but it also finds itself at the center of a row between London and Beijing that could prove fatal.

  • Nuclear Threats Are Increasing – Here’s How the U.S. Should Prepare for a Nuclear Event

    On the 75th anniversary of the bombings of Hiroshima and Nagasaki, some may like to think the threat from nuclear weapons has receded. But there are clear signs of a growing nuclear arms race and that the U.S. is not very well-prepared for nuclear and radiological events. Despite the gloomy prospects of health outcomes of any large-scale nuclear event common in the minds of many, there are a number of concrete steps the U.S. and other countries can take to prepare. It’s our obligation to respond.

  • Tracking the Neural Network's Nuclear Clues

    Following the 2011 earthquake in Japan, a tsunami disabled the power supply and cooling in three Fukushima Daiichi Nuclear Power Plant reactors. The reactors’ cores largely melted in the first 72 hours. The disaster helped inspire PNNL computational scientists looking for clues of future nuclear reactor mishaps by tracking radioactive iodine following a nuclear plant reactor breach.

  • Reducing Radioactive Waste in Dismantle Nuclear Facilities

    On Monday, France announced it was shutting down the country’s oldest nuclear reactor – and that additional twelve aging reactors will be dismantled by 2035. Scientists have designed a methodology for dismantling nuclear facilities while limiting the amount of toxic nuclear waste generated in the process.

  • France Shuts Down Its Oldest Nuclear Plant

    France gets 70 percent of its energy from nuclear reactors – it has 56 of them (only the United States, with 98, has more). Most of France’s nuclear reactors were built in the late 1960s and 1970s, and they are reaching – and in some cases, have exceeded — the 40-year limit on the safe operation of reactors. On Monday, France took offline its oldest nuclear reactor, and it will shut down 12 more by 2035.

  • Microreactors for Resilient Power in Puerto Rico

    Puerto Rico is home to 3.2 million American citizens, with all the energy needs of a modern economy. Most of the territory’s power, however, is generated by facilities dating from the 1960s, which is nearly thirty years older on average than mainland U.S. power plants. To meet the island’s energy demand without the need for more fossil fuels, one promising candidate is the use of microreactors.

  • Digital Twins of Nuclear Reactors Could Bring Down Nuclear Energy Costs

    Safe and more affordable nuclear energy is the goal of a new project which brings together researchers who specialize in nuclear energy technology and computer science. Among other things, the project will develop virtual copies of nuclear reactors, enabling smarter maintenance for current reactors and more automation for advanced reactors.

  • U.S. Ending Sanctions Waivers on Iran's Civilian Nuclear Program

    The United States has announced it will end sanctions waivers that allow Russian, Chinese, and European firms to carry out civilian nuclear cooperation with Iran, effectively scrapping the last remnants of the 2015 Iran nuclear deal, a move dismissed by Tehran as “desperate.”

  • Snapback of Sanctions under the Terms of the Nuclear Deal Is Fully Justified Today

    “If Iran today wants a serious discussion about sanctions relief, it should start by abandoning the key threat Tehran poses to international peace and security: its uranium enrichment program,” writes David Albright, a nuclear weapons expert and the president of the Institute for Science and International Security. “Instead, Iran holds its own people hostage over the deadly coronavirus outbreak in a cynical campaign for wholesale sanctions relief.” The willingness of Iran’s leadership to refuse epidemic aid and thus dramatically, and unnecessarily, increase the number of sick and dying Iranians; the willing of the leadership to intensify and deepen the severe economic deprivation and misery across the country – and do all that in order to grow an economically nonviable, menacing uranium enrichment program — “That alone should lead all to consider just what is the real purpose of Iran’s enrichment program,” Albright writes.

  • An Atomic Catch 22: Climate Change and the Decline of America's Nuclear Fleet

    Nuclear energy in the United States has become deeply unprofitable in the last decade, driven by a combination of aging infrastructure and other electricity sources like renewables and natural gas simply becoming cheaper to build and operate. While some in the environmental community may cheer nuclear’s decline, others are concerned. Love it or hate it, nuclear plays a unique role in the American electric sector, one for which we currently have no market-ready replacement, and its decline will likely make other environmental issues, particularly climate change, harder to solve.

  • Consequences Remain Decades After Chernobyl Disaster: UN

    The United Nations says persistent and serious long-term consequences remain more than thirty years after the explosion and fire at the Chernobyl nuclear power plant in Ukraine. The world body is marking International Chernobyl Disaster Remembrance Day on 26 April, the 34th anniversary of the accident that spread a radioactive cloud over large parts of Belarus, Ukraine, and Russia. The anniversary is being marked after fires recently burned in the 30-kilometer exclusion zone around the plant, raising concerns about the potential release of radioactive particles into the air.
