[en] The main activities of the Agency are reviewed: nuclear power trends; regulatory aspects of nuclear power; technical developments: Eurochemic, Halden, Dragon, food irradiation; gas-cooled fast reactors, isotopic batteries; nuclear data Centers

[en] The IMS has been conceived with the idea to study the magnetosphere as a whole single system, consisting of plasma that moves under the boundary conditions imposed by a cold, resistive, co-rotating ionosphere at its base, and a warm, collisionless, streaming solar wind at its top. Such study obviously requires co-ordinated observations from spacecraft, ground-based facilities, aircraft, balloons, and research rockets, conducted simultaneously at many different spatial locations under pre-planned circumstances

[en] This annual report describes the scientific research in Nuclear Physics Division from September 1980 to August 1981. The following subjects are studied: nuclear spectroscopy, high excitation energy nuclear states, reaction mechanisms with light ions, heavy-ion physics, intermediate energy physics, and perinuclear research. A list of publications and lectures is included

[en] The environmental significance of ³H releases prompted an IAEA-sponsored coordinated research programme on various aspects. Data were collected to help health physicists, radioecologists, radiobiologists and environmentalists to predict the behaviour of ³H in the major terrestrial ecosystems of the world. A common methodology was used to carry out a variety of projects in widely varying biomes, from tropical to arctic regions: in Belgium, on terrestrial food chains, with deposition of tritiated water (HTO) on crops and pasture, and incorporation of ³H into proteins, nucleic acids, etc.; in Finland, plots of pasture and forest were labelled by HTO, and plant uptake were studied; in France, ³H-content in water, in relation to different parts of vines, orange and olive trees in a Mediterranean climate; in the Federal Republic of Germany, contamination due to ³H-releases; in India, mean ³H-residence time in some tropical trees; in Mexico, ³H-persistence as free-water ³H and tissue-bound ³H in crops; in the Netherlands, ³H-metabolism in ruminants; in the Philippines, residence time in soil and in various commonly edible crops, and excretion time; in Thailand, half residence time in soil and local vegetation; in the USA, the effects of HTO vapour and liquid exposure in a wide range of climatic conditions, including organic fixation and concentration factors. An extensive bibliography is attached, and also annexes of laboratories and project titles; plant species, exposure and residence times; comparable lists for animals studied; scientific and common names of the species, and a glossary

[en] The following is a general review of the launch campaigns in which Germany is or will be involved in the near future, i.e. until the first quarter of 1975. During this period, the Mobile Raketenbasis will be conducting or preparing three separate campaigns in different parts of the world. The three campaigns are distinguished not only by their different locations, but also by the different scientific aims. This review, it is hoped, will highlight the possibilities and flexibility of the Mobile Raketenbasis

[en] This paper attempts to summarize the neutrino oscillation section of the Workshop on Future Directions in Particle and Nuclear Physics at Multi-GeV Hadron Beam Facilities. There were very lively discussions about the merits of the different oscillation channels, experiments, and facilities, but the authors believe a substantial consensus emerged

[en] ARIES (Autonomous Robotic Inspection Experimental System) is a semi-autonomous robotic system intended for use in the automatic inspection of stored containers of low level nuclear waste. The project is being performed by a team under the SCUREF (South Carolina University Research and Education Foundation) comprised of the University of South Carolina, and Clemson University, and their industrial partner Cybermotion Inc., with funding from METC, Morgantown, WV. The ARIES program is unusual in the level of cooperation between the universities and Cybermotion. By maintaining daily communications via telephone and E-Mall, participating in frequent meetings with each other and the end users, and by developing an open flow of (sometimes sensitive) technical information, the team has been able to build on a very broad base of intellectual strengths and existing technology without wasteful duplication. This base includes all of the navigation and control software and hardware developed by Cybermotion over nearly a decade and the deep technology resources of the university partners. It is anticipated that the result will be a technically advanced system that is much closer to a deployable configuration than is typical for this stage of research. In this decade of shrinking budgets, such relationships can provide a crucial advantage for all participants

[en] A general discussion is presented on the kinds of problem which with suitable co-ordination would form appropriate topics for university research. R and D work can be done in-house, or with an industrial contractor, or with a university or polytechnic. The criteria are examined. Involvement by universities and polytechnics, and topics and location, are considered further. (U.K.)

[en] CANDU reactors produce electricity cheaply and reliably, with miniscule risk to the population and minimal impact on the environment. About half of Ontario's electricity and a third of New Brunswick's are generated by CANDU power plants. Hydro Quebec and utilities in Argentina, India, Pakistan, and the Republic of Korea also successfully operate CANDU reactors. Romania will soon join their ranks. The proven record of excellent performance of CANDUs is due in part to the first objective of the vigorous R and D program: namely, to sustain and improve existing CANDU power-plant technology. The second objective is to develop improved nuclear power plants that will remain competitive compared with alternative energy supplies. The third objective is to continue to improve our understanding of the processes underlying reactor safety and develop improved technology to mitigate the consequences of upset conditions. These three objectives are addressed by individual R and D programs in the areas of CANDU fuel channels, reduced operating costs, reduced capital costs, reactor safety research, and IAEA safeguards. The work is carried out mainly at three centres of Atomic Energy of Canada Limited--the Chalk River Nuclear Laboratories, the Whiteshell Nuclear Research Establishment, and the Sheridan Park Engineering Laboratories--and at Ontario Hydro's Research Laboratories. Canadian universities, consultants, manufacturers, and suppliers also provide expertise in their areas of specialization
