  • The Benefits of Moving to an All-W87 ICBM Force the NNSA Is Proposing
    The Benefits of Moving to an All-W87 ICBM Force The NNSA is proposing to replace the W78 ICBM warhead with a new W87-1 warhead using a “W87- like” pit. A better alternative Replacing the 200 deployed W78s with the some of the 340 W87s in storage would bring several benefits: 1. Enhanced safety—much sooner: A major feature of the W87-1 is that it would use insensitive high explosives (IHE). As NNSA states in its report W78 Replacement Program (W87-1): Cost Estimates and Insensitive High Explosives: “Replacing the conventional high explosives (CHE) in the current W78 warhead with IHE is the single most significant weapon system change that improves the warhead’s safety and security.” But the W87 also uses IHE and could be deployed now, not in several decades. 2. Less demanding pit production schedule: The W87-1 would use new plutonium pits, which requires the NNSA to start up and then quickly ramp up its pit production from the current zero (and none since 2013) to 80 per year by 2030. As the NNSA states, this will be “challenging.” The alternative would obviate or significantly delay the need to produce 80 pits by 2030. 3. More realistic schedule overall: The NNSA faces significant schedule challenges in producing the W87-1, as it states in the FY19 Stockpile Stewardship & Management Plan: “Production is predicated on all newly manufactured components and a nuclear material manufacturing modernization strategy that relies on large, multi-year investments in component and material capabilities.” 4. Reduced NNSA workload: The NNSA and the weapons complex are already struggling to manage five simultaneous major work programs on weapons in the stockpile while also building the UPF and trying to establish a pit production capacity.

  • Tickling the Sleeping Dragon's Tail: Should We Resume Nuclear Testing?
    TICKLING THE SLEEPING DRAGON’S TAIL Should We Resume Nuclear Testing? National Security Report Michael Frankel | James Scouras | George Ullrich TICKLING THE SLEEPING DRAGON’S TAIL Should We Resume Nuclear Testing? Michael Frankel James Scouras George Ullrich Copyright © 2021 The Johns Hopkins University Applied Physics Laboratory LLC. All Rights Reserved. “Tickling the sleeping dragon’s tail” is a metaphor for risking severe consequences by taking an unnecessary provocative action. Its origin can be traced to the last year of the Manhattan Project at Los Alamos National Laboratory (LANL) in 1946. When investigating the critical mass of plutonium, LANL scientists usually brought two halves of a beryllium reflecting shell surrounding a fissile core closer together, observing the increase in reaction rate via a scintillation counter. They manually forced the two half-shells closer together by gripping them through a thumbhole at the top, while as a safety precaution, keeping the shells from completely closing by inserting shims. However, the habit of Louis Slotin was to remove the shims and keep the shells separated by manually inserting a screwdriver. Enrico Fermi is reported to have warned Slotin and others that they would be “dead within a year” if they continued this procedure. One day the screwdriver slipped, allowing the two half-shells to completely close, and the increased reflectivity drove the core toward criticality. Slotin immediately flipped the top half-shell loose with a flick of the screwdriver, but by then he had endured

Biography F-l iii Report to Congress: Assessment of the Safety of U.S. ~ Nuclear Weapons and Related Nuclear Test Requirements Abstract.The principal safety features included in the design of modern nuclear weapons are described briefly, and each nuclear weapon currently in the stockpile or under development is given a comparative safetyI rating from "A" through "D," indicating the extent to which these safety features are included in its design. The list is then narrowed by deleting weapons currently scheduled for retirement and short-range, surface-to-surface tactical nuclear weapons that will likely be returned to the U.S. and placed in storage. With the exception of the Minuteman and Trident ballistic missile warheads, all warheads in this projected future stockpile will have both of the most important design features that contribute to nuclear weapon safety: enhanced electrical isolation (EEl) and insensitive high explosive (IHE).

  • Transparency in Nuclear Warheads and Materials the Political and Technical Dimensions
    TRANSPARENCY IN NUCLEAR WARHEADS AND MATERIALS THE POLITICAL AND TECHNICAL DIMENSIONS EDITED BY NICHOLAS ZARIMPAS At a time when arms control is being deconstructed by some and a blueprint for its reconstitution is being sought by others, the enhancement of transparency in nuclear warheads and materials as a means to achieve deeper and irreversible nuclear reductions deserves urgent atten- tion. The contributions in this volume map out the progress made and identify and discuss the reasons why countries pos- sessing nuclear weapons are impeding transparency. The main focus is on the technical means and procedures that have been used, are under development or have been proposed for building, strengthening and institutionalizing transparency. The authors analyse the arrangements for the establishment of stockpile declarations, the verification of nuclear warhead status and dismantlement, the storage and disposal of fissile materials, as well as the monitoring of production facilities. This volume brings together a unique and wide body of information and in-depth analysis by an informed group of arms control experts and is expected to stimulate international debate on the subject of nuclear transparency. Dr Nicholas Zarimpas (Greece) was Leader of the SIPRI Project on Military Technology and International Security in 1999–2002. He previously worked for the European Commission and the Organisation for Economic Co-operation and Development, where he specialized in the nuclear fuel cycle and the manage- ment of plutonium. During the past 10 years he has acted as scientific secretary to several international technological and policy committees.

    Ghosts of the Future Kelvin Mason Independent researcher [email protected] Abstract This film (https://vimeo.com/182695880) explores the UK’s decision to replace its Trident nuclear weapons system. Due to the ‘alternative format’i, the script and a response to reviewers is printed below. The film’s narration draws upon an existentialist ethics to critique a politics and culture of nuclear weapons, Mutually Assured Destruction and deterrence. The film was made at an academic seminar intervention at the Atomic Weapons Establishment at Burghfield in Berkshire in June 2016. Thematically linking ‘war’ and (global) ‘warming’, the seminar explored nuclear weapons and energy as, literally, signature technologies of the Anthropocene. A particular phenomenological approach employs close observation and social participation in place as an ‘incandescence’ to illuminate wider geographies and diverse temporalities. Physically inhabiting the AWE space made visible these ‘ghosts’ and highlighted the inextricability of emotion and reason. The film argues that deterrence is antithetic to the key existentialist tenet of transcendence. Deterrence is immoral not (only) because it is defined by abominable revenge rather than justice, but because it shapes an oppressive politics and culture that preclude the attainment of freedom and the acceptance of a concomitant personal responsibility. Owning one’s radical freedom and responsibility is Sartre’s definition of ‘authenticity’, living the truth about ourselves. Keywords Trident; deterrence; existentialism; ethics; place Published with Creative Commons licence: Attribution–Noncommercial–No Derivatives Ghosts of the Future 150 Narrator’s Script Robert Macfarlane observes that, ‘We mostly respond to mass extinction with ‘stuplimity’: the aesthetic experience in which astonishment is united with boredom, such that we overload on anxiety to the point of outrage-outrage’.

  • W76-2 “Low-Yield” Warhead Fact Sheet*
    W76-2 “Low-Yield” Warhead Fact Sheet* The W76-2 “low-yield” Trident warhead, currently in production, is dangerous, unjustified, and redundant. Background: The W76-2 nuclear warhead is a new “low-yield” warhead called for by the Trump administration's 2018 Nuclear Posture Review. It will be mounted on the Trident II D5 ballistic missile, which is deployed on OHIO Class “Trident” ballistic missile submarines. Trident's only mission is strategic nuclear deterrence; the W76-2 turns this stated mission on its head. Legislation has been introduced to stop production of the W76-2. There is no “deterrence gap.” The United States spends approximately four times the amount as Russia each year on its nuclear arsenal—amounting to $61.3 billion for the U.S. in 2011 compared to $14.8 billion for Russia.1 The Trump administration is in the process of rebuilding this arsenal at an estimated cost of $1.7 trillion, with inflation, over the next 30 years. While this immense program is excessive, adds to a new arms race with Russia, and should be scaled back, Russia cannot doubt that the United States is serious about maintaining an unambiguously strong nuclear deterrent.2 The United States already deploys a variety of low-yield nuclear weapons. These include 150 B61 gravity bombs that can be set from 0.3 to 60 kilotons, and air-launched cruise missiles with yields of 5 to 150 kilotons. These weapons are being upgraded to extend their lifetimes, are are receiving improvements, including greater accuracy.3 For comparison, the W76-2 will be 6.5 kilotons.3 Nuclear war cannot be controlled.

  • History of the Nuclear Stockpile Robert S
    History of the Nuclear Stockpile Robert S. Norris, Thomas B. Cochran, and William M. Arkin he United States since 1945 has manufactured some 60,000 . nuclear warheads in 71 types configured for 116 weapon systems costing some $750 billion. This amounts to an Taverage production rate of about four warheads per day for 40 years. With the current rate of spending on warhead production exceeding that of the Manhattan Project, the present stockpile of some 25,500 warheads is once again on the rise. That the most basic facts about the stockpile are shrouded in secrecy and difficult to discover is troubling, given their importance. Absent from the voluminous literature about the nuclear age is any serious treatment of the history of the warhead stockpile. "Gadget:' "Little Boy:' and "Fat Man" have been the central characters in chronicles of the dawn of the nuclear era, but a history of their many successors remains to be written. Only preliminary data can be offered here,but a full analysis is likely to lead to new insights about the Cold War, the dynamics of the arms race, and features of the contemporary debate.1 . The nuclear warhead stockpile grew slowly at first. Because of a scarcity of materials and laborious production methods there were only seven hundred by 1950. But by the mid-1950s. with the pro- duction complex in place, the stockpile began growing by thousands of warheads per year until it reached its peak in 1967 at just under 32,000. By 1970- 1971 the stockpile had dipped to 27,000, then 236 Robert S.
