• European Powers "Deeply Worried" By Iran's Uranium Enrichment Plans

    Britain, France, and Germany say Iran’s apparent plan to install additional advanced centrifuges at its main nuclear enrichment facility is “deeply worrying” and contrary to the 2015 nuclear deal with world powers. A confidential report by the UN’s atomic watchdog, the International Atomic Energy Agency (IAEA), said Iran plans to install three more cascades of advanced IR-2m centrifuges in its underground plant at Natanz.

  • Iran Violating 2015 Nuclear Deal Again with Use of Advanced Centrifuges: Reuters

    Reuters obtained a confidential IAEA report which says that Iran plans to install more advanced uranium-enriching centrifuges at an underground plant in breach of its troubled deal with major powers. The confidential IAEA report said Iran plans to install three more clusters of advanced IR-2m centrifuges in the underground plant at Natanz, located about 300 kilometers south of the capital, Tehran.

  • Nuclear War could Take a Big Bite Out of the World's Seafood

    A new study reveals the damage that a nuclear war might take on wild-caught seafood around the world, from salmon and tuna to the shrimp in shrimp cocktails. The aftermath of such a conflict could put a major strain on global food security, an international team of scientists reports. The group estimates that a nuclear war might cut the amount of seafood that fishing boats are capable of bringing in worldwide by as much as 30 percent.

  • UN Watchdog Confirms New Construction at Iran's Natanz Nuclear Facility

    The United Nations’ nuclear watchdog agency said that Iran has begun construction of an underground centrifuge assembly plant near its nuclear facility at Natanz. International Atomic Energy Agency (IAEA) Director-General Rafael Grossi said in an October 28 interview in Berlin that the facility seems to be a replacement for one that exploded in July in what Tehran called a sabotage attack.

  • Looking for Evidence of the Construction of Iran’s New Centrifuge Assembly Plant: New Possible Preparations Identified

    This summer, Iran decided to construct a new underground centrifuge assembly plant, following the destruction of the above ground one at the Natanz enrichment site on 2 July 2020. So far, Iran has undertaken little visible work in the mountains adjacent to the Natanz enrichment site with the exception of possible construction preparations. A nearby gunnery range appears to have been converted to a construction support and staging area in the first half of September. Because of the added difficulties of building an underground site, the completion of a new centrifuge assembly plant able to assemble thousands of advanced centrifuges per year is unlikely in 2021.

  • Chinese Nuke Arsenal Next on Beijing’s “To-Do” List, U.S. Commander Warns

    The commander in charge of the U.S. military’s nuclear arsenal has warned that increasing China’s nuclear stockpile is “next” on Beijing’s “to-do list.” Speaking to reporters at the Pentagon, U.S. Strategic Command chief Adm. Charles Richard said that while the United States has “no margin” of error left to start recapitalizing its nuclear force, China has a proven record of steadily building its military.

  • Radiation Detection System to Protect Major U.S. Metropolitan Region

    An exercise last December at the Port Authority of New York and New Jersey was the culmination of a five-year effort to develop and deploy an automated, high-performance, networked radiation detection capability for counterterrorism and continuous city-to-region scale radiological and nuclear threat monitoring.

  • Ultrasensitive Measurements Detect Nuclear Explosions

    Imagine being able to detect the faintest of radionuclide signals from hundreds of miles away. Scientists have developed a system which constantly collects and analyzes air samples for signals that would indicate a nuclear explosion, perhaps conducted secretly underground. The system can detect just a small number of atoms from nuclear activity anywhere on the planet. In terms of sensitivity, the capability – in place for decades – is analogous to the ability to detect coronavirus from a single cough anywhere on Earth.

  • 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.

  • A Restart of Nuclear Testing Offers Little Scientific Value to the U.S. and Would Benefit Other Countries

    The U.S. tested nuclear bombs for decades. But at the end of the Cold War in 1992, the U.S. government imposed a moratorium on U.S. testing. in recent weeks, the Trump administration and Congress have begun debating whether to restart active testing of nuclear weapons on U.S. soil. We are two nuclear weapons researchers – a physicist and an arms control expert – and we believe that there is no value, from either the scientific nor diplomatic perspective, to be gained from resuming testing. In fact, all the evidence suggests that such a move would threaten U.S. national security.

  • Suspicions Mount of Foreign Hand in Fire at Sensitive Iranian Nuclear Site

    There is growing support among outside security experts for the notion that an “incident” at Iran’s main nuclear-enrichment facility last week was an act of sabotage in a shadow war aimed at setting back Tehran’s nuclear activities. Many analysts believe that a foreign state, possibly Israel, was behind the 2 July fire at the Natanz facility in Iran’s central Isfahan Province.

  • Setback for Iran’s Nuclear Program after Mystery Fire at Centrifuge Assembly Site

    New details of an Iranian nuclear facility damaged in a mysterious fire suggest Thursday’s incident is a much greater setback to Iran’s nuclear ambitions than Tehran has publicly admitted. The Washington-based Institute for Science and International Security identified the facility as a centrifuge assembly workshop at the Natanz Fuel Enrichment Plant in central Iran’s Isfahan province.

  • Nuclear Alarmism: Proliferation and Terrorism

    Alarmism about nuclear weapons is common coin in the foreign policy establishment, John Mueller writes. He notes that during the course of the Cold War, for example, the chief concern was that the weapons would somehow go off, by accident or by intention, devastating the planet in the process. More recently, the worry has been that terrorists would get their hands on nuclear weapons. Concerns about the dangers inherent in nuclear proliferation and in nuclear terrorism certainly seem overwrought, Mueller writes, concluding: “There may be reason for concern, or at least for interest and watchfulness. But alarm and hysteria (not to mention sleeplessness) are hardly called for.”

  • Nuclear Weapon Modernization Continues but Outlook for Arms Control Is Bleak: Report

    The just-released annual report from the Stockholm International Peace Research Institute (SIPRI) assesses the current state of armaments, disarmament, and international security. The report finds is that despite an overall decrease in the number of nuclear warheads in 2019, all nuclear weapon-possessing states continue to modernize their nuclear arsenals.

  • 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.”
