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.

This article examines public communication about atomic energy as an important vector in the political, institutional, and technological transformations of Ukraine's nuclear industry since the breakup of the USSR. It explores the ongoing effort to make the atom more domestic, familiar, human, and accessible against the not-so-distant backdrop of the Chernobyl nuclear disaster in 1986. The central focus of this article is the analysis of children's drawings of nuclear power stations produced for art contests organized by local nuclear information centers. (...) These contests and other activities of the centers have contributed to the increased visibility of nuclear power in Ukraine. The drawings reveal the inscription of the atom into complex representations about the Ukrainian nation, its past, present, traditions, and modernity. The analysis of these drawings as well as government and nuclear power station (NPP) documents, press articles, and interviews indicates that the notion of the “domestication” of the atom is a particularly appropriate way to describe the banalization of nuclear technologies in Ukraine.

Within science and technology studies, few approaches have generated more contention—or more misunderstanding—than the "actor-network" analyses of Callon, Latour, and Law. Although many have taken critical issue with this approach, few studies have engaged the strengths and weaknesses of actor-network theory on its own terms. This article presents two arguments that constitute a critical engagement across actor-network terrain. First, the author suggests that the confusion surrounding actor-network accounts lies partially in the ambiguous role played by "social context" and argues for (...) the political and explanatory importance of resketching the boundaries between the laboratory and society. Second, the author argues that a semiotic perspective is not necessarily an exclusive one and that different ways of telling stories about technoscientific practice can be combined usefully. These arguments are illustrated with a mostly Latourian account of the development of the STR Mark-I, the world's first "fully engineered" nuclear reactor. (shrink)

In the chemical production process, the temperature of the continuous reactor has nonlinear characteristics such as large inertia. An improved autodisturbance control method is proposed. By improving the tracking differentiator with adjustable parameters, the expanded state observer and the control structure obtained an improved automatic disturbance rejection control model and realized the optimal control of the nonlinear and large-delay systems. On the process control training system, the experiment of the continuous system process flow is compared with the anti-interference of the (...) Smith predictive compensation system, which uses an optimal set of data. The reactor temperature fluctuates, but the self-resistance is improved. The optimal overshoot of the disturbance is close to 0. Compared with the original antidisturbance controller, the antidisturbance time is not affected by the number of iterations, which reduces the high requirements on the accuracy of the parameters. Therefore, the improved automatic disturbance rejection control improves the operation and enhances the ability to resist external disturbance that changes the controlled object. (shrink)

In this article, we argue that scientists and technologists associated with the nuclear industry are building support for small modular reactors by advancing five rhetorical visions imbued with elements of fantasy that cater to various social expectations. The five visions are as follows: a vision of risk-free energy would eliminate catastrophic accidents and meltdowns. A vision of indigenous self-energization would see SMRs empowering remote communities and developing economies. A vision of water security would see SMR-powered desalination plants satisfying the (...) world’s water needs. A vision of environmental nirvana would see SMRs providing waste-free and carbon-free electricity to preserve the earth’s biosphere. A vision of space exploration would see SMRs assisting in the colonization of the moon, Mars, and possibly other worlds. These visions help create a symbolic convergence among promoters, serving to attract political and financial support, and erasing previous nuclear failures from public discourse. Moreover, underlying these visions is a technological utopian ideal world where SMRs would generate plentiful energy of multiple kinds, offering the necessary means for a life of comfort for all people by meeting various needs and without any environmental externalities or cause for concern about accidents.

Publics and policymakers increasingly have to contend with the risks of complex, safety-critical technologies, such as airframes and reactors. As such, ‘technological risk’ has become an important object of modern governance, with state regulators as core agents, and ‘reliability assessment’ as the most essential metric. The Science and Technology Studies literature casts doubt on whether or not we should place our faith in these assessments because predictively calculating the ultra-high reliability required of such systems poses seemingly insurmountable epistemological problems. (...) This paper argues that these misgivings are warranted in the nuclear sphere, despite evidence from the aviation sphere suggesting that such calculations can be accurate. It explains why regulatory calculations that predict the reliability of new airframes cannot work in principle, and then it explains why those calculations work in practice. It then builds on this explanation to argue that the means by which engineers manage reliability in aviation is highly domain-specific, and to suggest how a more nuanced understanding of jetliners could inform debates about nuclear energy.

The postwar investments by several governments into the development of atomic energy for military and peaceful uses fuelled the fears not only of the exposure to acute doses of radiation as could be expected from nuclear accidents or atomic warfare but also of the long-term effects of low-dose exposure to radiation. Following similar studies pursued under the aegis of the Manhattan Project in the United States, the “genetics experiment” discussed by scientists and government officials in Britain soon after the war, (...) consisted in large-scale low-dose irradiation experiments of laboratory animals to assess the effects of such exposures on humans. The essay deals with the history of that project and its impact on postwar genetics. It argues that radiobiological concerns driven by atomic politics lay at the heart of much genetics research after the war and that the atomic links are crucial to understand how genetics became an overriding concern in the late 20th century.

This simulation study is a fuzzy model-based neural network control method. The basic idea is to consider the application of a special type of neural networks based on radial basis function, which belongs to a class of associative memory neural networks. The novelty of this approach is the use of an RBF neural network controller in a model reference adaptive control architecture, based on a one-step-ahead Takagi–Sugeno fuzzy model. The objective is to control the concentration in a continuous stirred-tank reactor (...) highly non-linear system and to assure its stability by limiting the temperature rise generated from the irreversible exothermic reaction. This contribution will help to reduce environmental impact of chemical waste. (shrink)

In the mid-1940s, Argentina was partially isolated and ruled by a military regime. The political confrontation between the military and the scientific community as well as international pressures played a major role in the failure of the first attempts to cope with nuclear development. Only after the relationship between the military and local scientists was readjusted and control of atomic energy was placed in the hands of the Navy, and Argentina's international relations restored, did nuclear development begin to take off. (...) This paper examines the traumatic process of creating the political and institutional conditions for the reception of nuclear technology in a peripheral context. The key to shaping future policies was the decision made by Argentina's Atomic Energy Commission in April 1957 to construct its first research nuclear reactor instead of buying it as other countries such as Spain and Brazil were doing at the time.

On March 11, 2011, a magnitude 9.0 earthquake and thirty-eightmeter high tsunami destroyed Tokyo Electric’s Fukushima nuclear power complex. The disaster was not a high-damage, low-probability event. It was a high-damage, high-probability event. Massive earthquakes and tsunamis assault the coast every century. Tokyo Electric built its reactors as it did because it would not pay the full cost of a meltdown anyway. Given the limited liability at the heart of corporate law, it could externalize the cost of running (...) class='Hi'>reactors. In most industries, firms rarely risk tort damages so enormous they cannot pay them. In nuclear power, “unpayable” potential liability is routine. Privately owned companies bear the costs of an accident only up to the fire-sale value of their net assets. Beyond that, they pay nothing — and the damages from a nuclear disaster easily soar past that point. Government ownership could eliminate this moral hazard — but it would replace it with problems of its own. Unfortunately, the electoral dynamics in wealthy modern democracies combine to replicate nearly perfectly the moral hazard inherent in private ownership. Private firms will build reactors on fault lines — but so will governments. (shrink)

Life appears to be a natural property of matter, but the problem of its origin only arose after early scientists refuted continuous spontaneous generation. There is no chance of life arising ‘all at once’, we need the standard scientific incremental explanation with large numbers of small steps, an approach used in both physical and evolutionary sciences. The necessity for considering both theoretical and experimental approaches is emphasized. After describing basic principles that are available (including the Darwin-Eigen cycle), the search for (...) origins is considered under four main themes. These are the RNA-world hypothesis; potential intermediates between an RNA-world and a modern world via the evolution of protein synthesis and then of DNA; possible alternatives to an RNA-world; and finally the earliest stages from the simple prebiotic systems to RNA. The triplicase/proto-ribosome theory for the origin of the ribosome is discussed where triples of nucleotides are added to a replicating RNA, with the origin of a triplet code well-before protein synthesis begins. The length of the code is suggested to arise from the early development of a ratchet mechanism that overcomes the problem of continued processivity of an RNA-based RNA-polymerase. It is probable that there were precursor stages to RNA with simpler sugars, or just two nucleotides, but we do not yet know of any better alternatives to RNA that were likely to arise naturally. For prebiotic stages (before RNA) a flow-reactor model is suggested to solve metabolism, energy gradients, and compartmentation simultaneously – thus the intense interest in some form of flow reactor. If an autocatalytic cycle could arise in such a system we would be major steps ahead. The most likely physical conditions for the origin of life require further clarification and it is still unclear whether the origin of life is more of an entropy (information) problem (and therefore high temperatures would be detrimental), rather than a kinetic problem (where high temperatures may be advantageous).

Solving complex socio-technical problems, this paper claims, involves diverse knowledges (cognitive diversity), competing interests (social diversity), and pragmatism. To explain this view, this paper first explores two different cases: Canadian pulp and paper mill pollution and siting nuclear reactors in seismically sensitive areas of California. Solving such socio-technically complex problems involves cognitive diversity as well as social diversity and pragmatism. Cognitive diversity requires one to not only recognize relevant knowledges but also to assess their validity. Finally, it is suggested, (...) integrating the resultant set of diverse relevant and valid knowledges determines the parameters of the solution space for the problem. (shrink)

When its atmosphere processing plant's fusion reactor exploded, it turned it into a desolate, irradiated hunk of rock uninhabitable by humans for thousands of years. The explosion was not far off from what the surviving humans in Aliens were planning anyway: nuke the site from orbit. To set the stage for considering the military decisions of Colonial Marines from an ethical perspective, strap in like it's a simulated combat drop from low orbit. This chapter looks at the Aliens future of (...) the twenty‐second century. After the first tragic encounter with the Xenos in Aliens, the remaining humans are trying to figure out their next steps in the back of the armored personnel carrier (APC). Many of the ideas being tossed around in the APC (even slimy Carter Burke's) keep the Xenos distant and so actually reduce the threat, backing the humans away from the need to make decisions in a “supreme emergency”.

The 1979 partial nuclear reactor meltdown at Three Mile Island was simultaneously hyper-visible and hidden from public view. It was the subject of non-stop media attention, but its causes and consequences required expert explanation. No fire or explosion marked the moment when insensible radionuclides escaped the facility. Yet, residents recalled a variety of troubling sights, sounds, odors, tastes, and sensations. Public distrust percolated in the interstices between government assertions that little radiation had escaped the facility and residents’ sense memories of (...) the incident. This article traces intertwined networks of activists from Japan and Pennsylvania as they mobilized legally, politically, and scientifically to develop evidence about the offsite effects of Three Mile Island. Exploring the distinct cosmology of evidence that activists marshaled, the article shows how they placed the messy, contingent, dynamic living world at the center of inquiries about the meltdown’s consequences. Activists developed new practices of biological witness that reconfigured the interplay between scientific, legal, and moral authority, while concurrently reformulating sufferers’ subjectivities and notions of scientific objectivity. In the process, they suggested that environmental justice entailed epistemic justice. Their cosmology of evidence served as an argument and a material proof that the beloved but suffering living world, and the sciences used to understand it, could and should frame the governance of industrial society’s invisible harms.

Merck suppressed data on harmful effects of its drug Vioxx, and Guidant suppressed data on electrical flaws in one of its heart-defibrillator models. Both cases reveal how financial conflicts of interest can skew biomedical research. Such conflicts also occur in electric-utility-related research. Attempting to show that increased atomic energy can help address climate change, some industry advocates claim nuclear power is an inexpensive way to generate low-carbon electricity. Surveying 30 recent nuclear analyses, this paper shows that industry-funded studies appear to (...) fall into conflicts of interest and to illegitimately trim cost data in several main ways. They exclude costs of full-liability insurance, underestimate interest rates and construction times by using overnight costs, and overestimate load factors and reactor lifetimes. If these trimmed costs are included, nuclear-generated electricity can be shown roughly 6 times more expensive than most studies claim. After answering four objections, the paper concludes that, although there may be reasons to use reactors to address climate change, economics does not appear to be one of them. (shrink)

Four hundred seventy-six nuclear power plants are in operation or under construction around the world. Are concepts for designing and operating plants safely sufficient? Conventional approaches are premised on expectations of predictability and control of radiation release and on assumptions that plant operations are closed systems. Field observations in the industry find, however, that the periodic necessity to refuel, test safety equipment, and continuously upgrade plant designs introduces challenges to control not originally calculated. The social and cultural contexts of markets, (...) regulation, and work systems create additional contingencies. In this dynamic environment, reactor operations produce invaluable data about the states of the entire technology and organizational system. Rereading these dynamics as "experiments" suggests an alternative epistemol ogy that synthesizes science's values of doubt, discovery, and documentation with engineering's values of efficiency, optimization, and problem solving. This redefines plant-based risk handlers as ethologists, geologists, and anthropologists of an ecology of visible and invisible hazards. (shrink)

The contribution of this present paper is to propose a method that combines a chemical Brusselator reaction-diffusion system with a biological cell system via gap junction for controlling and visualizing the frequency and magnitude of chaotic intracellular calcium oscillations in two cell types, including nonexcitable cells and the glial cells. This produces a wide variety of oscillatory behaviors similar to those reported in numerous biological experiments. We particularly show that in the majority of chaos cases, the reactor to cell coupling (...) can induce the generation of regular calcium oscillations as the coupling strength is varied. Together with the proposed method of coupled models, the regularity of these chaotic oscillations enables us to gain better understanding and extensive insights into the overall coupling dynamics.

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 accidents at Three Mile Island and Chemobyl have slowed the development of commercial nuclear fission in most industrialized countries, although nuclear proponents are trying to develop smaller, allegedly “fail-safe” reactors. Regardless of whether or not they succeed, we will face the problem of radioactive wastes for the next million years. After a brief, “revisionist” history of the radwaste problem, Isurvey some of the major epistemological and ethical difficulties with storing nuclear wastes and outline four ethical dilemmas common to (...) many technological and environmental controversies. I suggest two solutions to these ethical dilemmas and show why they are also economical and realistic proposals. (shrink)
