• Nuclear wasteMaterials Currently Used to Store Nuclear Waste Accelerate Corrosion

    The materials the United States and other countries plan to use to store high-level nuclear waste will likely degrade faster than anyone previously knew because of the way those materials interact, new research shows. The findings show that corrosion of nuclear waste storage materials accelerates because of changes in the chemistry of the nuclear waste solution, and because of the way the materials interact with one another.

    New insights into rates of bedrock erosion by glaciers around the world will help to identify better sites for the safe storage of nuclear waste. The findings of a new research overturn earlier research, showing that erosion rates do not increase with the speed of glacier flow as quickly as previously anticipated.

  • ArgumentPentagon Deployment of New, “More Usable” Nuclear Weapon Is a Grave Mistake

    The Pentagon on Tuesday acknowledged that it has deployed a new, sea-based nuclear warhead capability. The move — first reported last week by the Federation of American Scientists — is the first in the Trump administration’s multibillion-dollar, multi-decade plan to replace and expand U.S. nuclear weapons capabilities. Daryl G. Kimball writes that the administration’s stated rationale for the new weapon is deeply flawed, and the decision to field the device only heightens the danger of escalation.

  • Doomsday clockIt Is Now 100 Seconds to Midnight

    The Bulletin of the Atomic Scientists’ Doomsday Clock is now closer to midnight than ever in its history. The Bulletin cites worsening nuclear threat, lack of climate action, and rise of “cyber-enabled disinformation campaigns” in moving the clock hand. December 2020 marks the 75th anniversary of the first edition of the Bulletin of the Atomic Scientists, initially a six-page, black-and-white bulletin and later a magazine, created in anticipation that the atom bomb would be “only the first of many dangerous presents from the Pandora’s Box of modern science.”

  • Radiation risksSecuring Radiological Sources on the Go

    Radioactive materials are a critical tool in a number of industrial applications, particularly oil and gas drilling and welding. While these sources are safe and well-regulated for their intended use; if lost or stolen the materials could be used by terrorists to make dirty bombs.

  • Iran’s nukesEuropean Unity on Iran Nuclear Deal May Be Cracking

    There are signs that cracks are beginning to appear in European unity over its backing of the 2015 Iran nuclear deal, or JCPOA, as allies come under growing pressure from the United States to abandon the agreement in the wake of Tehran’s downing of a passenger jet January 8. Iran announced this month it would ignore all restrictions on its nuclear enrichment activities, but insisted it was permitted to do so under the 2015 deal, because the U.S. was the first signatory to break the agreement.

  • Iran’s nukesIsrael Warns Iran is Closer to Nuclear Bomb

    Israeli military analysts say that by the end of 2020 Iran will have enough enriched uranium for one nuclear bomb. The assessment comes after recent tensions between the U.S. and Iran brought them to the brink of war. The United States pulled out of the Iran nuclear deal in 2018, and Israeli intelligence officials speculated that Iran would resume its efforts to acquire a nuclear bomb.

  • ArgumentHow Demise of Iranian Nuclear Deal Rekindles Israel’s Dilemma

    For Israel, it may be a case of “careful what you wish for.” Whatever its flaws, the Iran nuclear deal gave Israel a breather of sorts. Now its leaders face a grimly familiar predicament, and a ticking clock.

  • Iran’s nukesFrance: Iran Could Have Nuclear Weapon within One to Two Years

    French Foreign Minister Jean-Yves Le Drian has warned that Iran could have nuclear weapons in one or two years if Tehran continues to violate a landmark nuclear accord with world powers. Before the nuclear deal between Iran and the leading world powers was signed in October 2015, Iran’s “dash-to-the-bomb” break-out time was estimated to be between two and five months. The various clauses of the nuclear deal had increased Iran’s break-out time to 12-18 months – and the deal would have kept Iran’s nuclear program in that state until 2030. Since the U.S, withdrew from deal on 8 May 2018, Iran has systematically, if carefully and slowly, breached more and more of the restrictions imposed on its nuclear program in 2015.

    The Council on Foreign Relations has asked policy experts to rank thirty ongoing or potential conflicts based on how likely they are to occur or escalate in the next year, and their possible impact on U.S. interests. For the second year in a row, a highly disruptive cyberattack on critical infrastructure, including electoral systems, was the top-ranked homeland security–related concern. A mass-casualty terrorist attack was a close second. A confrontation between the United States and Iran, North Korea, or with China in the South China Sea remain the biggest concerns overseas.

    Iran’s attacks on Iraqi bases housing U.S. troops as Tehran announced it will no longer comply with restrictions on uranium enrichment may encourage North Korea to perfect its nuclear and missile technologies, experts said.

  • Iran’s nukesIran Abandons 2015 Nuclear Deal

    Iran says it is no longer limiting the number of centrifuges used to enrich uranium— a virtual abandonment of the 2015 nuclear deal. But the Sunday statement did not make any explicit threats that Iran is seeking a nuclear weapon — something Iran has always denied it wants to do. Its statement said Iran will still cooperate with the International Atomic Agency. President Donald Trump pulled the U.S. out in 2018.

  • Nuclear safetyHelping Keep U.S. Nuclear Deterrent Safe from Radiation

    Advanced modeling speeds up weapons research, development and qualification. It also lets researchers model changes in experimental conditions that increase the total radiation dose, change how fast a device gets that dose, and mix and match destructive elements like neutrons, energy and heat in environments that cannot be recreated in experimental facilities.

  • Perspective: Iran’s nukesUnderstanding Iran’s Nuclear Escalation Strategy

    Iran is back in the nuclear game. Eric Brewer and Ariane Tabatabi write that the United States and the remaining parties to the Iran nuclear deal must prepare for what may be a significantly more challenging year ahead with additional Iranian nuclear escalatory measures. “By withdrawing from the agreement and already firing its most potent rounds (i.e., oil and banking sanctions), the United States is limited in its ability to deter further Iranian nuclear advances. Iran, on the other hand, still has more chips it can play,” they write.

  • Nuclear securityThe Nexus Between Nuclear Energy & Nuclear Security

    By Greg Witt

    Despite the plentiful and relatively cheap energy available in the upper-income countries, nearly one billion people worldwide have no consistent access to electricity, with another one billion having reduced access to healthcare due to energy poverty and a further 2.7 billion relying on biomass as their primary source of energy. Any program hoping to ameliorate these challenges would almost certainly require a radical expansion in global electricity generation. While renewable energy sources, including solar, wind, and hydroelectric power, will inevitably play a role in any low-carbon future, any genuinely sustainable energy future would also require a massive investment in nuclear energy.
