SynopsisThe background to recent major advances in the construction and operation of fast reactors is outlined with particular reference to the Dounreay Prototype Fast Reactor. The advantages and disadvantages of sodium as a coolant of the high energy density assembly are discussed and an account given of the consequences of a leak and the precautions taken against this eventuality. Attention is drawn to the safety aspects of the system. The economics of the plans for fuel reprocessing are explained and an account given of the progress in the fabrication of fast reactor fuel pins. Finally the environmental impact of present and planned activities on the Dounreay site is presented in the context of participation in the European Collaboration on Fast Reactor Technology and attention drawn to the importance of the planning inquiry in progress at Dounreay.

ABSTRACT Uranium exploration increased over the past decade in response to an increase in the price of uranium, with more than 900 companies engaged in the global exploration on over 3,000 projects. Major economic discoveries of new uranium orebodies have been elusive despite global exploration expenditures of $3.2 billion USD, with most of the effort in historical uranium districts. The increased effort in exploration with minimal return can be described through the example of a cyclical model based on exploration and discovery in the prolific Athabasca Basin, Saskatchewan. The model incorporates exploration expenditure, quantities of discovered uranium, and the sequence of uranium deposit discoveries to reveal that discovery cycles are epochal in nature and that they are also intimately related to the development and deployment of new exploration technologies. Exploration in the Athabasca Basin can be divided into an early “prospector” phase and the current “model-driven”phase. The future of successful uranium exploration is envisaged as the “innovation exploration” stage in which a paradigmatic shift in the exploration approach will take the industry towards new discoveries by leveraging research and technology development. Effective engagement within the “innovation exploration” paradigm requires that exploration organizations recognize knowledge brokers, and adopt research, development, and technology transfer as a long-term, systematic strategy, including critical definition of exploration targets, identification of innovation frontiers needed, enhanced leadership to accurately portray the research and development imperative and elevation of the status of the research and development effort within the organizational system.

The article examines the main global problems of the modern world space, defining the main tendencies of overcoming the crisis and the further path of human development. Globalization indicates the general nature of most processes meaningful to mankind. Modern humanity represents an indivisible system of economic, political, social and cultural ties and interactions, which is significative for the unity of its future destiny. Informatization became the basis of globalization, reflecting the current level of technology development. Global problems are problems affecting all mankind, influencing the course of economic development and social sphere, also ecology and political stability. These problems require international cooperation, since none, even a highly developed State, is able solve them on its own. The number of hungry people in the world has increased over the past few years. Now every ninth person in the world is starving every day, suffering from a lack of nutrition. Both the food scarcity and hunger are among the greatest threats to the overall health of the human population exceeding malaria, tuberculosis or HIV. Responsibility for the planet should begin with responsibility for the country, because the crisis of a separate country complicates the world situation in the political aspect; ecological and resource crises jeopardize environmental equilibrium and complicate the problem of resources on a global scale; an economic crisis leads to social consequences in other countries.

Business Intelligence (BI) has been a top technology development concern for high-ranking IT executives over the past decade. The objective of BI is to use data analysis as a competitive weapon, deeply integrated into business processes. The ability of an organization to provide enterprise-level BI services depends heavily on its IT strategy, itself a function of existing technology investment. Previous research has described four IT architecture stages ranging from isolated applications to modular services, each with increasing complexity and service capabilities. Representatives from four companies were interviewed about the status of their BI activities, and the resulting data helps identify common barriers faced by these organizations in the provisioning of enterprise-level BI services. Interview results also describe the success of a limited-scope operational BI system by one of these firms, and the role of semantic data exchange technologies, primarily XML, in this system.

With the improvement of technology, technology began to gradually applied to every field, electric field inspection also began to gradually enable unmanned aerial vehicle (uav) inspection instead of manual inspection. Articles in the domestic and foreign research literature of unmanned aerial vehicle (uav) magnetic coupling resonance charging basis, this paper introduces the unmanned aerial vehicle (uav) magnetic coupling resonance charging technology development and application of the status quo, points out the problems in the current study of, offers a new way for the further research in this field.


As the need for breeder technology in the United States has receded into the more distant future, it has become clear that an alternative justification must be found for continued priority development of sodium-cooled fast-reactor technology. Both the modular high-temperature gas-cooled reactor and the liquid-metal-cooled reactor (LMR) have technical attributes that provide more simple and transparent solutions to some of the problems confronting the nuclear enterprise, in addition to their potential for greater market penetration, resource extension, and waste management improvements. For the past five years, the LMR development programme in the United States has attempted to use these technical attributes in more innovative ways to provide more elegant solutions for the practical commercial application of nuclear energy. This paper discusses the reasons and status of the technological approaches that have evolved to support these policy considerations. For the LMR, efforts are focused on four interrelated development thrusts: (1) increased use of standardization; (2) passive safety approaches; (3) modularity; and (4) improved fuel cycle approaches. The paper also discusses the status of related design activities being conducted by the General Electric Company and a team of U. S. vendors.
