• Nonproliferation Researcher Is Retracing Reactor Steps

    Nuclear materials can produce vast amounts of energy. This unique attribute can be harnessed through reactors to provide a reliable, low-carbon electricity source. It can also be used to make weapons.

  • ‘Risks of Nuclear Terrorism Are High and Growing.’ New Tools, Alliances, Renewed Focus Needed, experts recommend

    For roughly 80 years, the United States has managed the threat of nuclear terrorism through nonproliferation treaties, agency programs, intelligence activities, international monitoring support and more, withstanding the Cold War, the fall of the Soviet Union, and 9/11. A National Academies committee wants to ensure the U.S. remains prepared.

  • Iran Can Now Produce Enough Fissile Material for 5 Nuclear Bombs within 30 Days of Decision to Do So

    Iran notified the IAEA recently that over the next 3-4 weeks it would install eight cascades each containing 174 IR-6 centrifuges, about 1,400 in total, at the underground Fordow Enrichment Plant. The installation of eight more IR-6 cascades represents a dramatic increase in Fordow’s total enrichment capacity, meaning that by the end of the first month from a decision to “go nuclear,” Iran could produce a total of 145 kg of WGU, enough for five nuclear weapons.

  • Russian Wargame Practicing Tactical Nukes Use Is Warning to West

    Last month, the Russian defense ministry launched a multi-phase exercise near Ukraine meant to prepare its forces for using non-strategic nuclear weapons (NSNWs). In addition to the obvious purpose of preparing Russian troops to use tactical nuclear weapons in battle, the multi-stage exercise was also meant to signal to the West that it should refrain from escalating assistance to Ukraine, as well as to warn the U.S. and its allies that Russia may liberalize its conditions for using nuclear weapons.

  • Role of Nuclear Weapons Grows as Geopolitical Relations Deteriorate: SIPRI

    The nine nuclear-armed states—the United States, Russia, the United Kingdom, France, China, India, Pakistan, the Democratic People’s Republic of Korea (North Korea) and Israel—continued to modernize their nuclear arsenals and several deployed new nuclear-armed or nuclear-capable weapon systems in 2023.

  • Global Annual Nuclear Weapons Spending in 2023: $91.4 Billion

    In 2023, the nine nuclear-armed states spent a combined total of $91,393,404,739 on their arsenals – equivalent to $2,898 a second. A new report shows that $10.7 billion more was spent on nuclear weapons in 2023 than in 2022.

  • Analysis of the IAEA’s Iran NPT Safeguards Report - May 2024

    For the second time in its quarterly safeguards reports on Iran’s compliance with the Nuclear Non-Proliferation Treaty (NPT), the International Atomic Energy Agency (IAEA) has drawn attention Iran’s current ability to make nuclear weapons. Without strong and decisive action y the IAEA, Iranwill succeed in steadily augmenting its nuclear program penalty-free, enabling it to build a nuclear weapon more quickly than Western powers could detect and stop.

  • Could a U.S.-Saudi Nuclear Deal Spark Middle East Arms Race?

    One part of a predicted, closer US-Saudi relationship is particularly controversial. Experts fear Saudi Arabia may use a civilian nuclear energy program, supported by the US, to develop their own atomic bombs.

  • Modeling the Threat of Nuclear War

    It’s a question that occupies significant bandwidth in the world of nuclear arms security: Could hypersonic missiles, which fly at speeds of least five times the speed of sound, increase the likelihood of nuclear war? As part of his MIT doctoral studies in nuclear science and engineering, Eli Sanchez investigated whether hypersonic missiles threaten global security.

  • Nuclear Expertise Guides Global Nonproliferation Innovation

    Researchers tackling national security challenges at the U.S. Department of Energy’s Oak Ridge National Laboratory are upholding an 80-year legacy of leadership in all things nuclear. Today, they’re developing the next generation of technologies that will help reduce global nuclear risk and enable safe, secure, peaceful use of nuclear materials worldwide.

  • Focused and Fast

    In response to an urgent DOD request, multidisciplinary teams across Sandia delivered in a big way for international security: Enhanced surety program meets urgent request.

  • Is Nuclear Deterrence Ethical and Legal?

    To state the obvious the nuclear situation will become more manageable and tolerable when great power relations are relaxed. When and if current tensions ease it would be wise to look for ways to reduce even more the risks of a nuclear calamity. If the weapons cannot be completely eliminated, however, then neither can the risks of the worst imaginable outcomes. Little can be gained by pretending otherwise.

  • Trump's Possible Return Reignites South Korea Nuclear Debate

    South Korean calls to acquire nuclear weapons, which were subdued for the past year following steps to strengthen the U.S.-South Korea alliance, are once again bubbling to the surface ahead of the possible return of former U.S. President Donald Trump.

  • Iran's Nuclear Activities 'Raises Eyebrows' at IAEA

    Iran’s enrichment of uranium and a lack of access to international monitors is fueling suspicions about its nuclear activities. The International Atomic Energy Agency said its committed to promoting dialogue with Tehran.

  • Its Deterrence Strategy Weakened, Iran Faces Pressure to Hit Israel

    Iran’s strategy of deterrence against Israel has suffered greatly since the outbreak of the Gaza war — particularly after the brazen attack on its consulate in the Syrian capital on April 1. the deadly strike on its consulate in Damascus may compel Iran to take direct action, experts say.
