[en] This report proposes an inventory of knowledge in geothermal energy (high and low enthalpy) in 55 countries of the world concerned by this resource. For each country, a sheet briefly indicates currently exploited and potential fields, produced and foreseen powers, and some field characteristics (fluid nature, temperature, number of drilled wells), proposes a brief overview of the sector organization (indication of national bodies, and of foreign companies intervening in the country), and states some general remarks related to the local energy policy, and, in some cases, research orientations
[en] The HTR was brought to technical maturity during the last 15 years: AVR-reactor plant is operating since 1968; coolant outlet-temperatures of 950 °C have been succesfully demonstrated for many years by AVR. Apart from little R+D-effort, HTRs for electrical power and process steam generation can be built. But the long term strategic importance of HTR will be the real high temperature area, the task to reduce Germany's dependency on imported primary energy, especially crude oil and natural gas by refining our own reserves of primary energy. Our resources of ''dirty'' primary energy, hard coal and lignite, have to be converted into clean secondary energy carriers, as synthetic natural gas (SNG), methanol and hydrogen. This conversion has to be done with minimum environmental pollution. Conventional autothermal technologies of coal conversion are polluting the atmosphere to a remarkable extent.
[en] This document focus on Niger Republic mineral industries related points that are: socio-political and economical context; specific characters such as administrative, juridical and fiscal environment; citizens employment and training; actual situation and energy projects; transport; existing mining companies, construction materials enterprises and projects presentation; effect of mining sector and construction material on national economy and prior major problems to be solved
[fr]Ce document comprend des points lies a l'industrie minerale au Niger qui sont: le contexte socio-politique et economique; les caracteres specifiques tel que l'environnement administratif, juridique et fiscal; l'emploi et la formation des citoyens; situation actuelle et projets energetiques; le transport; la presentation des societes d'exploitation miniere et entreprises de materiaux de construction existantes et projets; les statistiques de production et d'exportation; l'impact du secteur mines et materiaux de construction sur l'economie nationale et les grands problemes prioritaires a resoudre
[en] The paper discusses the nuclear technology takeover, acceptance and adoption; technology transfer contents and structure; the structure of local acceptance; the role, contents and significance of individual preparations with particular acceptance; nuclear technology transfer and takeover organization model; role of network planning within the process of technology transfer, takeover, acceptance and adaptation; as well as the role and model of completion of local infrastructure as required for technology transfer and acceptance.

[en] The development of nuclear energy for peaceful purposes has had a series of big international scientific and technical conferences as major milestones. The first was, of course, the United Nations Geneva Conference in 1955, which released a wealth of information which had hitherto been classified. This conference gave rise to a worldwide enthusiasm for the potential and possibilities of nuclear power. The three following Geneva Conferences in 1958, 1964, and 1971 showed a successive slow change in character reflecting the change in the nature of the information exchange which was taking place, the new role of smaller and more specialized meetings, and fast and extensive literature dissemination systems. Steadily, these conferences turned from the original role of international information exchange among scientists and technicians to one of summarizing a wealth of available information in order to present it to those who were to take planning and programming decisions in each nation, reflecting also the hopes and the great investments required in nuclear power. The IAEA, established in 1957, provided the UN with a scientific secretariat for the last two Geneva Conferences, and itself organized the Conference on Nuclear Power and its Fuel Cycle in Salzburg in 1977 at a time when the closing of the nuclear fuel cycle was a focal point of interest
[en] This project was initiated in response to expressed requirements by a number of utilities for a method to guide the scoping of a cost-effective preventive maintenance program for power plants. A guide was prepared and workshops were held to present the model reflected in the guide for developing a PM program. The model includes the identification of critical equipment items to be considered, the establishment of potential scope and frequency with which PM activities should be performed on this equipment, and the presentation of methods to perform cost/benefit and program optimization analyses consistent with the utility's level of resource commitment to PM. The guide also indicates the manpower requirements for developing a PM program using the model by skill level and number. (author)
[en] The author discusses the reasons for science transfer to developing countries. He mentions the impact of science on industrial and technological development in such countries. Furthermore he describes the activities of the IAEA and UNESCO in this field. (HSI).
[en] The paper describes a systematic method for the description of systems and equipment for nuclear power plants (NPP) of the PWR, BWR, HWR and WWER types. This method allows easy search for the equipment of different types of NPP and enables the formulation of statements and decision of the manufacturers which take part in deliveries for nuclear power program.
