ISBN 0-252-02296-3. £22.00.A decade after the end of the Cold War, the culture and technology of nuclear (...) weapons had lost much of the overt sense of dread they once inspired. The decline in international tension following the end of the communist regimes of the Soviet bloc produced a massive shift in the ideology of the nuclear in the 1990s. The de-targeting and dismantling of large numbers of nuclear weapons and the demise of the threat of nuclear annihilation created new conditions both for international security and for the writing of nuclear history. With the declassification and release of large quantities of official documentation from the former adversaries, as well as the fiftieth anniversary of the bombings of Hiroshima and Nagasaki in 1995, a burst of histories of various aspects of the nuclear age have appeared over the last ten years, exploring not just the technopolitics, strategy and operational logistics of the Cold War and the arms race, but the cultural history of the nuclear age, its imagery, its architecture, its oppositional politics and its effects on the landscape, national and regional economies and cultures and indeed everyday life. At a time of global economic and political uncertainty and the emergent threat of capricious international terrorism and new nuclear proliferation, the apparent certainties of the Cold War now even evoke a certain nostalgia, and its artefacts and structures are being recast as ‘heritage’.

Following with the discovery of the electron by J. J. Thomson at the end of the nineteenth century a steady elucidation of the structure of the atom occurred over the next 40 years culminating in the discovery of nuclear fission in 1938–1939. The significant steps after the electron discovery were: discovery of the nuclear atom by Rutherford (Philos Mag 6th Ser 21:669–688, 1911 ), the transformation of elements by Rutherford (Philos Mag 37:578–587, 1919 ), discovery of artificial radioactivity (...) by Joliot-Curie and Joliot-Curie (Comptes Rendus Acad Sci Paris 198:254–256, 1934 ), and the discovery of the neutron by Chadwick (Nature 129:312, 1932a , Proc R Soc Ser A 136:692–708, 1932b ; Proc R Soc Lond Ser A 136:744–748, 1932c ). The neutron furnished scientists with a particle able to penetrate atomic nuclei without expenditure of large amounts of energy. From 1934 until 1938–1939 investigations of the reaction between a neutron and uranium were carried out by E. Fermi in Rome, O. Hahn, L. Meitner and F. Strassmann in Berlin and I. Curie and P. Savitch in Paris. Results were interpreted as the formation of transuranic elements. After sorting out complex radio-chemistry and radio-physics O. Hahn and F. Strassmann came to the conclusion, beyond their belief, that the uranium nucleus split into smaller fragments, that is nuclear fission. This was soon followed in 1939 by its theoretical interpretation by L. Mietner and O. Frisch. (shrink)

Community detection is a major issue in network analysis. This paper combines a socio-historical approach with an experimental reconstruction of programs to investigate the early automation of clique detection algorithms, which remains one of the unsolved NP-complete problems today. The research led by the archaeologist Jean-Claude Gardin from the 1950s on non-numerical information and graph analysis is retraced to demonstrate the early contributions of social sciences and humanities. The limited recognition and reception of Gardin's innovative computer application to the humanities (...) are addressed through two factors, in addition to the effects of historiography and bibliographies on the recording, discoverability, and reuse of scientific productions: (1) funding policies, evidenced by the transfer of research effort on graph applications from temporary interdisciplinary spaces to disciplinary organizations related to the then-emerging field of computer science; and (2) the erratic careers of algorithms, in which efficiency, flaws, corrections, and authors’ status, were determining factors.

Drawing upon the concepts of civic epistemologies and sociotechnical imaginaries, this article delves into the history of nuclear energy in Portugal, analyzing the ways in which the nuclear endeavor was differently enacted by various sociopolitical collectives – the Fascist State, post-revolutionary governments and the public. Following the 1974 revolution - known as the Carnation Revolution - this paper analyzes how the nuclear project was fiercely contested by a vibrant anti-nuclear movement assembled against the construction of (...) the Ferrel Nuclear Plant, the first sociotechnical controversy in Portugal, paving the way for the emergence of a combative civic epistemology. Supported by semi-structured interviews with scientists, activists and local residents of Ferrel and the analysis of historical material, this article presents the failed Portuguese nuclear endeavor as an emblematic case study to explore the co-production of science and society, in particular the role of revolutionary processes in the unfolding of sociotechnical controversies.

In my paper I argue for mobilising recent material heritage at universities in teaching history of contemporary science. Getting your hands dirty in the messy worlds of the laboratory and the storage room, and getting entangled with the commemorative practices of scientists and technicians does not belong to the common experiences of students in history and philosophy of science. Despite the recent material turn in cultural studies, students’ engagement with the material world often remains a linguistic exercise, extending (...) at most to an excursion to the sanitised and academically encultured world of the museum exhibit.I contrast this approach by drawing on experiences of taking students to the Atomei, Germany’s oldest research reactor at the Garching campus of the Munich University of Technology. Decommissioned since 2000, the installation and its history are still controlled by scientists. Studying contemporary laboratories and their materiality has so far been the domain of sociologists and ethnographers. I argue for opening these spaces to historians of science and engaging with the ‘unfinished’ material world of contemporary science. Taking the material seriously beyond the linguistic turn and asking students to explore laboratories and other sites of knowledge production challenges existing histories and historiographies. By exploring local university departments and their recent histories through their material heritage, we can observe everyday science and confront scientists and technicians’ cultures with those of historians’. By engaging with recent material heritage as historians and archivists, students can make an important contribution to enhancing the awareness about this heritage, its implications for history writing, as well as its documentation and preservation.

Discusses the methods of moral reasoning, the evaluation of moral arguments, nuclear war theory, the policy of nuclear deterrence, and the effect of nuclear weapons on nonnuclear powers.

Communities of nuclear workers have evolved in distinctive contexts. During the Manhattan Project the UK, USA and Canada collectively developed the first reactors, isotope separation plants and atomic bombs and, in the process, nurtured distinct cadres of specialist workers. Their later workplaces were often inherited from wartime facilities, or built anew at isolated locations. For a decade, nuclear specialists were segregated and cossetted to gestate practical expertise. At Oak Ridge Tennessee, for example, the informal ‘Clinch College of (...) class='Hi'>Nuclear Knowledge’ aimed to industrialise the use of radioactive materials. ‘We were like children in a toy factory’, said its Director: ‘everyone could play the game of designing new nuclear power piles’. His counterpart at Chalk River, Ontario headed a project ‘completely Canadian in every respect’, while the head of the British project chose the remote Dounreay site in northern Scotland because of design uncertainties in the experimental breeder reactor. With the decline of secrecy during the mid-1950s, the hidden specialists lauded as ‘atomic scientists’ gradually became visible as new breeds of engineers, technologists and technicians responsible for nuclear reactors and power plants. Mutated by their different political contexts, occupational categories, labour affiliations, professional representations and popular depictions, their activities were disputed by distinct audiences. This chapter examines the changing identities of nuclear specialists and the significance of their secure sites. Shaped successively by Cold War secrecy, commercial competition and terrorist threats, nuclear energy remained out of site for wider publics and most nuclear specialists alike. The distinctive episodes reveal the changing working experiences of technical workers in late-twentieth and early twenty-first century environments. (shrink)

The argument of ‘Nuclear Song’ is pursued at various extremities of the damage done to poetic imagination by what the poem never quite names as ‘the’ nuclear. ‘Nuclear Song’ opens with an epigraph asking how far human agency, even the resources of poetic song, are complicit with anthropogenic radioactivity. Is there a poetic grammar for representing nuclear plumes and umbrellas, the yellow cake and toxic clouds of nuclear trauma that radiate from Japan through the English (...) language? Can poetry even be written after and in the light of Fukushima? What future-proof forms of memory stewardship and signage can survive the ruins of nuclear wastelands? What happens to the lyric stanza when it is irradiated, its very atoms split and fused in new compounds? This song of the nuclear anthropocene attempts to find nodes and notes of resistance to the metaphorical radiation emanating from the dark ecology of nuclear horizons. Amid the ruins, alternative ecologies of mourning and reconciliation with nuclear pains are imagined: imagination dead imagine. The unnatural history born witness to concludes with glimpses of wild boars in the radioactive environs of Fukushima, boars in search of the truffles of scarred art with which the poem begins.

This essay will examine the polemic and poetic means through which three Indigenous Australian writers discuss the repercussions and risks associated with nuclear power, waste and weaponry as an existential and material threat to the mythopoeic creation stories, totemic systems and landforms which sustain Indigenous Australian belief. This essay will follow the establishment of a media ecology through which discourses of technological harm in Oodgeroo Noonuccal's “No More Boomerang” lay the foundation for Australian Indigenous anti-nuclear activist poetics and (...) highlights the relationship between language, belief and technology. Oodgeroo's [Kath Walker] “No More Boomerang” will be read as a precursor to the experimental expression of Lionel Fogarty's “Foot Walking and Talking – Atomic Confusion” as well as the procedural methodologies behind Natalie Harkin's “Zero Tolerance.” It will be argued that Indigenous-led representations of nuclear weaponry as an ontologic-existential threat can only be properly critiqued when framed through the constructs of race, nationhood and the history of colonization in Australia.

The widespread adoption of radioisotopes as tools in biomedical research and therapy became one of the major consequences of the "physicists' war" for postwar life science. Scientists in the Manhattan Project, as part of their efforts to advocate for civilian uses of atomic energy after the war, proposed using infrastructure from the wartime bomb project to develop a government-run radioisotope distribution program. After the Atomic Energy Bill was passed and before the Atomic Energy Commission was formally established, the Manhattan Project (...) began shipping isotopes from Oak Ridge. Scientists and physicians put these reactor-produced isotopes to many of the same uses that had been pioneered with cyclotron-generated radioisotopes in the 1930s and early 1940s. The majority of early AEC shipments were radioiodine and radiophosphorus, employed to evaluate thyroid function, diagnose medical disorders, and irradiate tumors. Both researchers and politicians lauded radioisotopes publicly for their potential in curing diseases, particularly cancer. However, isotopes proved less successful than anticipated in treating cancer and more successful in medical diagnostics. On the research side, reactor-generated radioisotopes equipped biologists with new tools to trace molecular transformations from metabolic pathways to ecosystems. The U.S. government's production and promotion of isotopes stimulated their consumption by scientists and physicians, such that in the postwar period isotopes became routine elements of laboratory and clinical use. In the early postwar years, radioisotopes signified the government's commitment to harness the atom for peace, particularly through contributions to biology, medicine, and agriculture. (shrink)

The nation’s nuclear power industry is in trouble. The number of operating reactors continues to decline, while only one new plant is scheduled to open and it is well behind schedule and 50% over budget. The article will investigate the possibility of a nuclear revival in this country by first analyzing the troubled history of the light water reactor, a technology that dates back to the 1950s, and one the federal government choose to pursue to ensure America’s (...) technological leadership, and one the nuclear manufactures heavily promoted to ensure profitability. All of this resulted in a rush to nuclear power in the 1960s, but abruptly ended a little more than a decade later, due largely to the exorbitant costs of constructing a nuclear plant. The article then discusses the chances of a nuclear comeback, focusing on new reactor designs, which are less complex and cheaper to construct but will be dependent upon how seriously global warming is viewed by the public and elected officials.

In the ever-expanding field of nuclear history, studies of ‘nuclear culture’ are becoming increasingly popular. Often situated within national contexts, they typically explore responses to the nuclear condition in the cultural modes of literature, art, music, theatre, film and other media, as well as nuclear imagery more generally. This paper offers a critique of current conceptions of ‘nuclear culture’, and argues that the term has little analytical coherence. It suggests that historians of ‘nuclear (...) culture’ have tended to essentialize the nuclear to the detriment of historical analysis, and that the wide variety of methodological approaches to ‘nuclear culture’ are simultaneously a strength and a more significant weakness, in that they have little shared sense of the meaning of the term, its theoretical underpinnings or its analytical purchase. The paper then offers a study of Ewan MacColl's 1946 playUranium 235, whose career reveals much about the diversity of cultures of the nuclear in post-war Britain. The study moves us away from a single, homogeneous ‘British nuclear culture’ towards a pluralistic critical history of cultural responses to nuclearization. These responses, I conclude, should be seen as collectively constitutive of the nuclear condition rather than as passive reflections of it. (shrink)

The enormous destructive power of present stocks of nuclear weapons poses the greatest threat to public health in human history. Technical changes in weapons design are leading to an increased emphasis on the ability to fight a nuclear war, eroding the concept of deterrence based on mutually assured destruction and increasing the risk of nuclear war. Medical planning and civil defence preparations for nuclear war have recently been increased in several countries although there is little (...) evidence that they will be of significant value in the aftermath of a nuclear conflict. These developments have raised new ethical dilemmas for those in health professions. If there is any risk of use of weapons of mass destruction, then support for deterrence with these weapons as a policy for national or global security appears to be incompatible with basic principles of medical ethics and international law. The primary medical responsibility under such circumstances is to participate in attempts to prevent nuclear war. (shrink)

As the title suggests, this book is a series of imagined dialogues concerning the ethical issues raised by the practice of nuclear deterrence. The dialogues take place between various professional philosophers who meet each other at a conference on philosophy and the arms race. Among the issues covered are the possibility of justifying the use of nuclear weapons in retaliation, the morality of nuclear threats, hostage-holding, the relation between morality as it applies to individuals and morality as (...) it applies to states, political realism, feminism and peace-making, and so on. The book does not break new ground in its discussions of any of these issues, but my sense is that that is not really its point. It is, rather, an introductory work which rehearses a variety of issues and arguments in a way that is accessible to those with little or no training in philosophy. For this sort of reader the book may be quite useful. Many passages in the dialogues address issues of interest to people concerned about nuclear weapons and make the sorts of points that one might overhear in discussions of these topics by earnest and intelligent people. One important merit of the book is that the range of topics covered is broader than that normally found in the philosophical literature. (shrink)

With the passing of the Cold War, a chapter in the history of nuclear deterrence has come to an end. Nuclear weapons remain, however, and nuclear deterrence will again be practiced. Rather than simply assume that the policy of deterrence has worked we need to learn the proper lessons from history in order to ensure that its mistakes are not repeated. Professor Lee furnishes us with the kind of analysis that will enable us to learn (...) those lessons. This 1993 book is the first post-Cold War assessment of nuclear deterrence. It provides a comprehensive normative understanding of nuclear deterrence policy, examining both its ethical and strategic dimensions. The book poses the question: What kind of nuclear policy, if any, deserves both moral and prudential endorsement? (shrink)

The first nuclear engineers emerged from the Manhattan Project in the USA, UK and Canada, but remained hidden behind security for a further decade. Cosseted and cloistered by their governments, they worked to explore applications of atomic energy at a handful of national labs. This unique bottom-up history traces how the identities of these unusually voiceless experts - forming a uniquely state-managed discipline - were shaped in the context of pre-war nuclear physics, wartime industrial management, post-war politics (...) and utopian energy programmes. Even after their eventual emergence at universities and companies, nuclear workers carried the enduring legacy of their origins. Their shared experiences shaped not only their identities, but our collective memories of the late twentieth century. And as illustrated by the Fukushima accident seven decades after the Manhattan project began, this book explains why they are still seen conflictingly as selfless heroes or as mistrusted guardians of a malevolent genie.

This article examines the attempt by the Kingdom of Morocco—a country of pivotal geopolitical importance in the late 1970s and early 1980s—to secure a research reactor. It finds that by treating that reactor as a diplomatic object, we can observe the different diplomatic frameworks in which that object was conceived of, contextualized, and negotiated. The historical emergence of these frameworks occurred in close relationship with the IAEA, which acted as an intermediary linking various administrations, programs, and countries, including Morocco. In (...) the end, this history reveals that the late Cold War nuclear world involved multilateral actions and forces, some of which encouraged Morocco in its bid to acquire a reactor, but others of which left that same reactor orphaned and unfinished.

The nuclear engineer emerged as a new form of recognised technical professional between 1940 and the early 1960s as nuclear fission, the chain reaction and their applications were explored. The institutionalization of nuclear engineering channelled into new national laboratories and corporate design offices during the decade after the war, and hurried into academic venues thereafter proved unusually dependent on government definition and support. This paper contrasts the distinct histories of the new discipline in the USA and UK (...) (and, more briefly, Canada). In the segregated and influential environments of institutional laboratories and factories, historical actors such as physicist Walter Zinn in the USA and industrial chemist Christopher Hinton in the UK proved influential in shaping the roles and perceptions of nuclear specialists. More broadly, I argue that the State-managed implantation of the new subject within further and higher education curricula was shaped strongly by distinct political and economic contexts in which secrecy, postwar prestige and differing industrial cultures were decisive factors.

Criticism of nuclear weapons policies often misses the target through ignorance of the policies that are actually in effect. This essay recounts the development of American nuclear weapons policies, together with a history of the criticisms of these policies presented by nuclear strategists and moral philosophers.

This book advocates for the United States to abolish nuclear weapons, arguing its necessity in terms of the harmful consequences of nuclear deterrence. Kultgen's argument is based on conceptions of human rights and is couched in terms accessible to the disciplines that address human affairs in the social sciences, history, arts, and humanities.

There was more than one response to the nuclear age. Countering well-documented attitudes of protest and pessimism, Muriel Howorth (1886–1971) models a less examined strain of atomic enthusiasm in British nuclear culture. Believing that the same power within the atomic bomb could be harnessed to make the world a ‘smiling garden of Eden’, she utilized traditionally feminine domains of kitchen and garden in her efforts to educate the public about the potential of the atom and to ‘safeguard’ it (...) on their behalf. Boldly entering an overtly masculine arena in which, as a woman and a layperson, she was doubly an ‘other’, Howorth used a variety of publications, organizations and staged events to interpret atomic science and specifically to address women. Her efforts, dating roughly from 1948 to 1962, preceded but had broad overlaps with official Atoms for Peace programmes, and culminated in the formation of the Atomic Gardening Society in 1960 to promote the cultivation of gamma-irradiated seeds by British gardeners.

The acquisition of a nuclear power reactor from the North American company Westinghouse in 1964 not only brought atomic practices and knowledge to Spain but also introduced new methods of industrial organization and management, as well as regulations created by organizations such as the US Atomic Energy Commission and the International Atomic Energy Agency. This article analyzes the history of the knowledge, regulations and experimental practices relating to radiation safety and protection that traveled with this reactor to an (...) industrial space: the Zorita nuclear power plant. Within this space, the appropriation, use, and coproduction of knowledge and practices were conditioned by political, economic, industrial and social factors, and by the engineers, researchers and other professionals who contributed expert knowledge. Material held in the Tecnatom Historical Archive—the engineering company that coordinated construction of the plant—is the main source for this work, which delves into the history of knowledge and atomic technologies and adds to the historiography of radiological protection in Spain.

For more than a decade, Iran has been referring to a fatwa issued by its Supreme Leader, Ali Khamenei, proscribing nuclear weapons. The fatwa, however, not only failed to influence the process that led to the resolution of Iran’s nuclear crisis, but also has been met with a good deal of skepticism. The most commonly held suspicions about the credibility of the fatwa can be summed up in five central questions: Has the nuclear fatwa actually been issued? (...) Does the fatwa apply to all the aspects of nuclear weapons including their production, possession and use? What is the juridical status of the fatwa? Was the nuclear fatwa issued only to deceive other nations? Is the fatwa really irreversible? This article tries to answer these questions by providing a chronological review of the fatwa and analyzing all the relevant statements by Khamenei. The analysis is conducted against the background of Islamic principles, Shi’a jurisprudence and the history of the Islamic Republic of Iran. The article concludes that the fatwa is a credible religious decree and could indeed contribute to the cause of nuclear disarmament. (shrink)

The development of nuclear energy technologies in the second half of the 20th century came with great hopes of rebuilding nations recovering from the devasta-tion of the Second World War or recently released from colonial rule. In coun-tries like France, India, the USA, Canada, Russia, and the United Kingdom, nuclear energy became the symbol of development towards a modern and technologically advanced future. However, after more than six decades of experi-ence with nuclear energy production, and in the (...) aftermath of the Fukushima nuclear disaster, it is safe to say that nuclear energy production is not without its problems.Some of these problems have their origins in the very materiality of the technolo-gies involved. For example, not only does the use of highly radioactive materials give rise to risks for the current generation (e.g., in the potential for disaster when reactors melt down) but high-level radioactive waste from nuclear energy production presents a serious intergenerational problem for which an acceptable final solution or its implementation remains elusive. Moreover, nuclear energy technologies have specific social and political consequences. For example, they have been said to be authoritarian technologies (Winner, 1980), requiring cen-tralized authority, secrecy, and technocratic decision-making. While some of these problems could have been foreseen before nuclear energy technologies were introduced, others only arose after these technologies were already integrated into the social and infrastructural fabric of our lives. Addition-ally, new technologies (e.g., Generation III, III+ and IV reactors) are still being developed, bringing with them new and uncertain hazards and risks. Ignorance and uncertainty about the possible deleterious effects of introducing a new technology are inevitable, especially if the technology is complex, large time-scales are involved, or risks depend on social or political factors unforeseen in the design stage. However, this should not deter us from developing and intro-ducing new technologies. Rather, it should motivate us to organize these ‘exper-iments’ with new technologies in society in such a way that we can learn about their possible hazards and risks as effectively and responsibly as possible (van de Poel, 2011, 2015). In this way, it is possible to minimize risks and avoid unwant-ed moral, social or political developments. However, organizing such experi-ments responsibly also means that one could come to the conclusion that continuing an experiment is no longer responsible or desirable. Should we be prepared for such a scenario, and if so, how could we do that? One possible strategy to tackle this issue is that the technology and its introduction should be reversible. The aim of this thesis is to further explore this strategy by answering the following main research question (RQ) and accompanying subquestions (SQ):RQ: What are the implications of reversibility for the responsible develop-ment and implementation of nuclear energy technologies?SQ1: Under what conditions can nuclear energy technologies be considered reversible?SQ2: Why should nuclear energy technologies be reversible?SQ3: If so, how could the reversibility of nuclear energy technologies be achieved?After the introductory chapter 1, the chapters that form the main body of this dissertation each provide a distinct contribution to answering the three subques-tions and, by extension, the main research question. Guided by three historical case studies of nuclear energy technology development (i.e., India, France and the USA), chapter 2 answers the first subquestion by formulating the two condi-tions under which it can be considered reversible, i.e., 1) the ability to stop the further development and deployment of a that technology in society, and 2) the ability to undo the undesirable outcomes (material, institutional or symbolic) of the development and deployment of the technology. Chapter 3 subsequently tackles the second subquestion by establishing the general desirability of technological reversibility by virtue of its relation to responsibility in Emmanuel Levinas’ ethical phenomenology. It argues that technology development is a legitimate response to responsibility but inevitably falls short of the responsibility that inspires it, incessantly calling for technological and political change in the process. Having thus argued that nuclear energy technologies should ideally be reversible, chap-ters 4 and 5 work towards specific strategies to achieve technological reversibil-ity. Chapter 4 first investigates the processes that make it difficult to stop the further development and implementation of a nuclear energy technology in society, thus provid-ing input on how to fulfill the first condition for the reversibility of nuclear energy technologies. To do so, it presents a phenomenological perspective on technology and its adoption based on the work of Alfred Schutz. It also explores different ways in which technology adoption drives the processes of path depend-ence towards technological lock-in. Chapter 5 examines the history of geological disposal of high-level radioactive waste in the USA. It identifies a number of concrete policy pitfalls that could lead to lock-in and that should consequently be avoided. It also presents a number of general design strategies that could facilitate the undoing of undesirable consequences of a technology, thus providing input on how to fulfill the second condition for the reversibility of nuclear energy technol-ogies.Chapter 6 summarizes the central findings of the thesis and explains how these help to answer the research questions. On top of this, it reflects on a number of complications connected to reversibility considerations. Based on this, it is concluded that the question of irreversibility and reversibility is context- and technology-specific and a matter of degree. The chapter concludes with a reflec-tion on generalizations and limitations of the results. Finally, chapter 7 discusses the implications of this dissertation’s results for responsibly experimenting with nuclear energy technologies in society. (shrink)
