    Full text link
    A version of the pn-continuum-QRPA is outlined and applied to describe the Gamow-Teller strength distributions for ÎČÎČ\beta\beta-decaying open-shell nuclei. The calculation results obtained for the pairs of nuclei 116^{116}Cd-Sn and 130^{130}Te-Xe are compared with available experimental data.Comment: 8 pages, 3 figures, To appear in the proceedings of "Nucleus-2007: Fundamental problems of nuclear physics, atomic power engineering and nuclear technologies" Voronezh, Russia, June 25-29, 200

    Interactive Graphic Simulation: An Advanced Methodology to Improve the Teaching-Learning Process in Nuclear Engineering Education and Training

    Nowadays, computer simulators are becoming basic tools for education and training in many engineering fields. In the nuclear industry, the role of simulation for training of operators of nuclear power plants is also recognized of the utmost relevance. As an example, the International Atomic Energy Agency sponsors the development of nuclear reactor simulators for education, and arranges the supply of such simulation programs. Aware of this, in 2008 Gas Natural Fenosa, a Spanish gas and electric utility that owns and operate nuclear power plants and promotes university education in the nuclear technology field, provided the Department of Nuclear Engineering of Universidad PolitĂ©cnica de Madrid with the Interactive Graphic Simulator (IGS) of “JosĂ© Cabrera” (Zorita) nuclear power plant, an industrial facility whose commercial operation ceased definitively in April 2006. It is a state-of-the-art full-scope real-time simulator that was used for training and qualification of the operators of the plant control room, as well as to understand and analyses the plant dynamics, and to develop, qualify and validate its emergency operating procedures

    Education and Training of Future Nuclear Engineers Through The use of An Interactive Plant Simulator.

    The International Atomic Energy Agency (IAEA) sponsors the development of nuclear reactor simulators for education, or arranges the supply of such simulation programs [1]. Aware of this, the Department of Nuclear Engineering of the Universidad Politécnica de Madrid was provided in 2008 with the Interactive Graphical Simulator of the Spanish nuclear power plant José Cabrera, whose operation ceased definitively in 2006. According with the IAEA-TECDOC-1411 [2] , the simulator is a Graphical Simulator, used for training of main control room personnel, technical support engineers, and operations management. This paper presents all the work performed at the Department to turn the simulator into a teaching/learning tool, to be use in the nuclear engineering studies following guidance found in [3]

    녾튾 : As the chairman of KEPIC, the Korea Electric Power Industry Code Committee, for the past 15 years, C.K. Lee has mobilized and managed 350 engineering professors and professional engineers dispatched from six engineering-related academic societies. KEPIC’s 2005 edition consists of five parts contained in 83 volumes or some 27,000 pages, about 3.2 meters thick. Dr. Lee is also a former Commissioner on the Atomic Energy Commission of South Korea, and a former chairman of the International Nuclear Societies Council. This article is adapted from Dr. Lee’s book-length presentation at the Summer Institute of the World Nuclear University, held in Korea in August 2007. A previous article, “A Nuclear Perspective from Asia,” appeared in the Winter 2002-2003 21st Century. The author can be reached at [email protected]

    Creating a Canadian profession: the nuclear engineer, c. 1940-1968

    Get PDF
    Canada, as one of the three Allied nations collaborating on atomic energy development during the Second World War, had an early start in applying its new knowledge and defining a new profession. Owing to postwar secrecy and distinct national aims for the field, nuclear engineering was shaped uniquely by the Canadian context. Alone among the postwar powers, Canadian exploration of atomic energy eschewed military applications; the occupation emerged within a governmental monopoly; the intellectual content of the discipline was influenced by its early practitioners, administrators, scarce resources, and university niches; and a self-recognized profession coalesced later than did its American and British counterparts. This paper argues that the history of the emergence of Canadian nuclear engineers exemplifies unusually strong shaping of technical expertise by political and cultural context

    The rise and fall of the fast breeder reactor technology in the UK: between engineering “dreams” and economic “realities”?

    Get PDF
    This report explores the evolution of the fast breeder nuclear reactor programmes in the UK, from the period of great promises and expectations in the 1950s and 1960s towards their progressive abandonment in the 1980s and 1990s. The project, of which this report is an element, aims thereby to draw lessons relevant for the current “nuclear renaissance” and medium-term planning on the future of nuclear power. Given that the fast breeder programmes were closely interlinked with the general evolution of nuclear power in the UK, this report includes a fairly detailed historical description of this more general ‘nuclear context’. This primarily chronological description of the evolution of the UK fast breeder programmes provides a basis for a comparison between the evolution of the British and French fast breeder reactor programmes. A central question in such a comparison concerns the lateness of the abandonment of the fast breeder programme in France, as compared to most other countries developing this technology. The cross-country comparison will explore the relative influence of the contextual and historical conditions within which the nuclear technologies have evolved in France and the UK on the one hand, and the ‘universal’ factors common to the evolution of socio-technical systems in general on the other. This exploratory research was based on documentary analysis and eleven interviews of experts involved in, or with knowledge of, the UK fast breeder reactor (FBR) programmes
