Before WW2 Danish geologists had found traces of uranium in Greenland. But being squeezed from both sides in the escalating Cold War between East and West, in the first decade after WW2 the Danish government did not support expeditions to explore Greenland's potential uranium deposits. The situation changed abruptly after President Eisenhower's Atoms for Peace address in December 1953, as a result of which a Danish Atomic Energy Commission (AEK) was set up in early 1955. Besides building a (...) large atomic energy research facility (Risø) one of AEK's first initiatives was to support big scale uranium expeditions to South-West Greenland. The ultimate goal for the leaders of AEK was to liberate Denmark from its dependence on imported fossil fuels by developing Danish nuclear reactors, fuelled by natural uranium from Greenland. In the late 1960s, after more than a decade of uranium explorations, this was still a goal, albeit much more long term. For many reasons the hunt for uranium in Greenland after WW2 was unsuccessful, but the main ones were Danish sovereignty concerns, techno-scientific nationalism and devastating institutional clashes of interests. The present paper will explore these problems. (shrink)

The ‘how’ and the ‘why’ of knowledge circulation is explored in a study of the encounter between American and British nuclear scientists and engineers who together developed a gas centrifuge to enrich uranium in the 1960s. A fine-grained analysis of the transnational encounter reveals that the ‘how’ engages a wide variety of sometimes mundane modes of exchange in a series of face-to-face interactions over several years. The ‘why’ is driven by the reciprocal wish to improve the performance of the (...) centrifuge, though this motive is embedded in the asymmetric field of the ‘special relationship’ in nuclear matters between the United Kingdom and the United States. The result of the encounter is co-produced, hybrid knowledge in which the national provenance of the contributions from each side of the Atlantic is at once diluted and a contested site for the affirmation of national power.

The study uncovers the drama of Stei Baita (Romania), a former uranium mine, which experienced during the communism period, an intensive industrialization. This shaped the territorial pattern, cultural, economic and social relationships, with a tremendous impact on the quality of the environment which was sacrificed against a rapid of a so-called economic growth. Stei Baita is a classic example of legacy mine land and the authors aim is to capture and assess all important aspects of sustainable development within this (...) study-case of disadvantaged community living in a radon prone area. More specifically, authors introduce their responses to several questions: (1) What do we know about social, economic and environmental capital of the selected settlement?; (2) Is the legacy of a uranium mine the platform of debate for negotiating for sustainable development?; and (3) What is the role of ethics in the current context of Stei Baita? Within the framework of analysis, equity, seen as part of ethics, is valued both as the premise of the debate and mandatory requirement for human development that should target sustainability. Authors have not discussed truths, but positions on identified problems by investigating community members’ perceptions. Thus, peculiarities of this community are dealt within a thematic context (e.g., resources and environment, individual development, social system). Finally, ethics is valued as social construct built by negotiating interpretations of morally desirable situations and behaviors accepted in a particular society at a certain historical moment. This view is consistent with ethical relativism which denies the existence of a unique moral truth and which sets the understanding of Stei Baita context on the path of the “new ethics”. The “new ethics” depicts the world in nuances, allowing society to surpass obstacles to the progress of understanding. (shrink)

According to Rivka Weinberg, gametes are like enriched uranium: both are hazardous materials. Exposing human beings to enriched uranium can result in radioactivity and decreased life expectancy, while exposing sperm and ova to each other can result in the creation of needy innocent persons with full moral status. Weinberg argues that when we engage in activities that put our gametes at risk of joining with others and growing into persons, we assume the costs of that risky activity. She (...) calls this the Hazmat Theory of parental responsibility. The theory is novel and important, and has far-reaching consequences for the ethics of procreation, parenting, and population, implying among other things that that the only way to avoid acquiring parental responsibilities may be to “abstain from sexual intercourse or surgically interfere with our gamete-release system.” For these reasons the theory merits careful scrutiny. In this article I criticize the theory's account of how parental responsibility is acquired and its treatment of the standard of care expected of gamete possessors, and argue that it fails to properly account for a distinction between procreative costs and parental responsibility. Even if gametes are hazardous, it does not follow that parental responsibility in Weinberg's sense is acquired whenever one brings new persons into existence. (shrink)

ConclusionThe common assumption that Becquerel had no special reason to study uranium compounds in his search for substances emitting penetrating radiation cannot explain (a) Becquerel's own accounts, which refer to his choice as due to “the peculiar harmonic series of bands”; (b) Becquerel's systematic test of all uranium compounds (and metallic uranium), in contrast to his neglect of other substances; and (c) Becquerel's belief in invisible phosphorescence as an explanation of the radiation emitted by uranium compounds, (...) even after his discovery that non-luminescent and metallic uranium also emit penetrating radiation.By comparing Becquerel's older studies of uranium to his radioactivity research, this paper has presented a reconstruction that can explain all of these points above. According to the historical evidence presented here, it is likely that Becquerel concentrated his attention on uranium and its compounds because the mechanical theory of luminescence opened up the possibility that, precisely in the case of uranium and its compounds, a violation of Stokes's law could occur, and penetrating short-wavelength radiation could be emitted through a special type of phosphorescence.

An integrated approach of the topics ‘population’, ‘energy’ and ‘climate’ results in conclusions contrary to public opinion. Population growth will lead to disaster ten times faster than global warming. 2.5 billion people in the poor countries account for a population growth of one billion every 12 years. Fertility rates decrease with increasing gross domestic products (GDPs). Increasing GDPs correlate with increasing energy consumption. Wind power and solar energy are too expensive for the poor countries. Low-price energy can only be produced (...) with coal, gas, oil and uranium. Therefore, many more coal-fired power stations and nuclear reactors need to be built and hopefully population growth will slow down. Once population is stabilized environmental issues can be addressed. (shrink)

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)

An empirical interaction potential has been developed primarily to simulate displacement cascades in a UO 2 matrix. After a bibliographical survey revealed that the potentials discussed in the literature are not entirely suitable for describing point defects and their migration, we decided to adapt the most representative of the existing potentials. Our objective was specifically to reproduce transport phenomena, which are fundamental to a satisfactory description of atomic displacement cascades. The modified potential more correctly describes the experimental energies of formation (...) and migration of point defects as well as the oxygen diffusion coefficients in the superionic phase. Thermal expansion, heat capacity and enthalpy are also better modelled over a wide temperature range. The new potential is much more transferable than earlier potentials fitted mainly to the properties of perfect crystals. The initial simulated atomic displacement cascades showed that this potential is well suited to the description of structural effects created by decelerating recoil nuclei in a UO 2 matrix. (shrink)
