The purpose of the Comprehensive Nuclear-Test-Ban Treaty (CTBT) is to establish a legally binding ban on nuclear weapon test explosions or any other nuclear explosions. The Preparatory Commission for ...the CTBT Organization (CTBTO PrepCom) is developing the International Monitoring System (IMS) that includes a global network of 80 stations to monitor for airborne radionuclides upon entry into force of the CTBT. All 80 radionuclide stations will monitor for particulate radionuclides and at least half of the stations will monitor for radioxenon. The airborne radionuclide monitoring is an important verification technology both for the detection of a radionuclide release and in the determination of whether the release event originates from a nuclear explosion as opposed to an industrial use of nuclear materials. Nuclear power plants and many medical isotope production facilities release radioxenon into the atmosphere. Low levels of a few particulate isotopes, such as iodine, may also be released. Detections of multiple isotopes are useful for screening the radionuclide samples for relevance to the Treaty. This paper examines the anticipated joint detections in the IMS of noble gas and particulate isotopes from underground nuclear explosions where breaches in the underground containment vents from low levels to up to 1% of the radionuclide inventory of the resulting fission products to the atmosphere. Detection probabilities are based on 844 simulated release events spaced out at 17 release locations and one year in time. Six different release (venting) scenarios, including two fractionated scenarios, were analyzed. When ranked by detection probability, 11 particulate isotopes and one noble gas isotope (133Xe) appear in the top 20 isotopes for all six release scenarios. Using the 11 particulate isotopes and the one noble gas isotope, the IMS has nearly the same detection probability as when 45 particulate and 4 noble gas isotopes are used. Thus, a limited list of relevant radionuclides may be sufficient for treaty verification purposes. The probability that at least one particulate and at least one radioxenon isotope would be detected in the IMS from the release events ranged from 0.15 to 0.86 depending on the release scenario.
In December 1994 Ukraine gave up the third-largest nuclear arsenal in the world and signed the Non-Proliferation Treaty, having received assurances that its sovereignty would be respected and secured ...by Russia, the United States, and the United Kingdom. Based on original and heretofore unavailable documents, Yuri Kostenko’s account of the negotiations between Ukraine, Russia, and the US, reveals for the first time the internal debates of the Ukrainian government, as well as the pressure exerted upon it by its international partners. Kostenko presents an insider’s view on the issue of nuclear disarmament and raises the question of whether the complete and immediate dismantlement of the country’s enormous nuclear arsenal was strategically the right decision, especially in view of the 2014 annexation of Crimea by Russia, one of the guarantors of Ukraine’s sovereignty under denuclearization.
Atomic Steppe tells the untold true story of how the obscure country of Kazakhstan said no to the most powerful weapons in human history. With the fall of the Soviet Union, the marginalized Central ...Asian republic suddenly found itself with the world's fourth largest nuclear arsenal on its territory. Would it give up these fire-ready weapons-or try to become a Central Asian North Korea?This book takes us inside Kazakhstan's extraordinary and little-known nuclear history from the Soviet period to the present. For Soviet officials, Kazakhstan's steppe was not an ecological marvel or beloved homeland, but an empty patch of dirt ideal for nuclear testing. Two-headed lambs were just the beginning of the resulting public health disaster for Kazakhstan-compounded, when the Soviet Union collapsed, by the daunting burden of becoming an overnight nuclear power.Equipped with intimate personal perspective and untapped archival resources, Togzhan Kassenova introduces us to the engineers turned diplomats, villagers turned activists, and scientists turned pacifists who worked toward disarmament. With thousands of nuclear weapons still present around the world, the story of how Kazakhs gave up their nuclear inheritance holds urgent lessons for global security.
Moral theologians, defense analysts, conflict scholars, and nuclear experts imagine a world free from nuclear weapons At a 2017 Vatican conference, Pope Francis condemned nuclear weapons. This ...volume, issued after the 60th anniversary of the Cuban Missile Crisis, presents essays from moral theologians, defense analysts, conflict transformation scholars, and nuclear arms control experts, with testimonies from witnesses. It is a companion volume to A World Free from Nuclear Weapons: The Vatican Conference on Disarmament (Georgetown University Press, 2020). Chapters from the perspectives of missile personnel and the military chain of command, industrialists and legislators, and citizen activists show how we might achieve a nuclear-free world. Key to this transition is the important role of public education and the mobilization of lay movements to raise awareness and effect change. This essential collection prepares military professionals, policymakers, everyday citizens, and the pastoral workers who guide them, to make decisions that will lead us to disarmament.
Researchers must improve ways to verify weapons declarations and collaborate on nuclear power, argues R. Scott Kemp. Researchers must improve ways to verify weapons declarations and collaborate on ...nuclear power, argues R. Scott Kemp.
China is significantly expanding the size and sophistication of its nuclear forces. Over the summer of 2021, researchers using satellite imagery discovered three separate fields of intercontinental ...ballistic missile (ICBM) silos under construction in the deserts of north-central China. If each silo is eventually equipped with a missile, the Chinese nuclear arsenal capable of striking the continental US could triple in size. Furthermore, the US government estimates that China’s nuclear arsenal could number 1000 warheads by 2030, with at least 200 deployed on long-range platforms.

In September 1980, eight Catholic activists made their way into a Pennsylvania General Electric plant housing parts for nuclear missiles. Evading security guards, these activists pounded on missile ...nose cones with hammers and then covered the cones in their own blood. This act of nonviolent resistance was their answer to calls for prophetic witness in the Old Testament: “They shall beat their swords into plowshares, and their spears into pruning hooks. Nation shall not take up sword against nation; they shall never again know war.”
Plowshares explores the closely interwoven religious and social significance of the group’s use of performance to achieve its goals. It looks at the group’s acts of civil disobedience, such as that undertaken at the GE plant in 1980, and the Plowshares’ behavior at the legal trials that result from these protests. Interpreting the Bible as a mandate to enact God’s kingdom through political resistance, the Plowshares work toward “symbolic disarmament,” with the aim of eradicating nuclear weapons.
Plowshares activists continue to carry out such “divine obediences” against facilities where equipment used in the production or deployment of nuclear weapons is manufactured or stored. Whether one agrees or disagrees with their actions, this volume helps us better understand their motivations, logic, identity, and ultimate goal.
Station RN33 on Mount Schauinsland near Freiburg, Germany, is part of the International Monitoring System monitoring radioxenon in air (131mXe, 133Xe, 133mXe, and 135Xe) for verification of the ...Comprehensive Nuclear Test Ban Treaty. Here, we present data from phase II testing of a new system, Xenon International at RN33, July 14th, 2021 to Jan 22nd, 2022, together with SPALAX data from the same time period. Radioxenon could be detected in 473 of 719 samples, among them many multiple isotope detections. Activity concentrations of spiked and selected environmental samples were verified by laboratory reanalysis. The sensitivity of Xenon International for radioxenons is up to one order of magnitude better for the metastable isotopes than that of the SPALAX, with a shorter sampling duration of 6 h.
•Phase II test of a new radioxenon detection system at monitoring station RN33 of the CTBTO International Monitoring System.•Radioxenon detected in 66% of samples.•6h sampling time and increased sensitivity compared to SPALAX currently in operation.
