[en] In the United States, coal provided 56 percent of the electricity generated in 1992. Nuclear energy was the next largest contributor, supplying 22 percent. Natural gas provided 9 percent, while hydro-electric and renewables together supplied another 9 percent. Currently, the 109 nuclear power plants in the U.S. have an overall generating capacity of 99,000 MWe. To improve efficiency, safety, and performance, the lessons of 30 years of experience with nuclear powerplants are being incorporated into design criteria for the next generation of U.S. plants. The new Advanced Light Water Reactor plants will feature simpler designs, which will enable more cost-effective construction and maintenance. To enhance safety, design margins are being increased, and human factors are being considered and incorporated into the designs

[en] The predictions of energy needs in Poland up to 2038 have been presented. The nuclear power contribution in them have been discussed taking into account different developing options. The ecological consequences have been predicted and compared for variants presented

[en] In this paper, developments in the world for utilization of nuclear energy and, in parallel to these developments, works undertaken in Turkey are summarized. Besides this, future prospects in the field of nuclear energy in the world and in Turkey, and our opinion about the action to be taken in our county, in the light of past experiences of nuclear power projects that could not be succeeded, are presented

[en] The status and prospects of nuclear power development in the newly-independent state in the territory of the former Soviet Union are considered. The prerequisites as well as the scientific - technical and industrial basis for the implementation of the national nuclear programs - technical and industrial basis for the implementation of the national nuclear programs are discussed. The tendencies in development of a new generation of advanced reactors are described. (author)

[en] Electricity generation, like any economic activity, leads to costs that can be grouped in two categories: (a) private or internal and (b) external. Private costs are those paid by the buyers and sellers of energy within the market system. The external costs, however, are not included in the market price mechanism as they accrue to third parties other than the buyer and the seller. External costs include environmental external costs and non-environmental external costs. There are two conditions for the existence of external costs: (a) market failure, or the inability of markets to account for the cost of environmental impacts of energy generation and the market structure and (b) government or policy failure, or the policies that cause private generators to pay either higher or lower costs than they would if these interventions did not exist. A third reason can be added for the existence of non-environmental externalities: energy security, or certain costs faced by society as a result of over-reliance on imported energy. Section A introduces the concept of external costs and benefits. Section B looks at the environmental externalities of energy generation. The procedure is to develop the methodology to estimate what are known as externality adders, i.e. a monetary value for the environmental costs and benefits associated with selected generation technologies, expressed in pence per kilowatt-hour. The result is an 'adder' because, in principle, the sum can be added to the private cost of generating electricity to obtain a measure of the 'full' or 'social' cost. The selected generation technologies are conventional coal, wind power, small-scale hydro, energy crops, incineration of municipal solid waste and energy recovery from landfill. The data reported are based on the application of the technologies in Scotland, but the methodology can be applied anywhere. Section C takes a brief look at the non-environmental externalities including the general theory and evidence from the United Kingdom, including the non-fossil fuel obligation, a system for encouraging energy generation from nuclear fuels and renewable resources. Section D discusses various strategies for internalizing external costs of conventional forms of energy, including emission taxes and tradable emission permits. (author)

[en] The impact of power generation on environment is becoming an ever increasing concern in decision making when considering the energy options and power systems required by a country in order to sustain its economic growth and development. Hydrogen is a strong emerging candidate with a significant role as a clean, environmentally benign and safe to handle major energy carrier in the future. Its enhanced utilization in distributed power generation as well as in propulsion systems for mobile applications will help to significantly mitigate the strong negative effects on the environment. It ia also the nuclear power that will be of utmost importance in the energy supply of many countries over the next decades. The development of new, innovative reactor concepts utilizing passive safety features for process heat and electricity generation are considered by many to play a substantial role in the world's energy future in helping to reduce greenhouse gas emissions. This report produced by IAEA documents past and current activities in Member States in the development of hydrogen production as an energy carrier and its corresponding production through the use of nuclear power. It provides an introduction to nuclear technology as a means of producing hydrogen or other upgraded fuels and to the energy carries hydrogen and its main fields of application. Emphasis is placed on high-temperature reactor technology which can achieve the simultaneous generation of electricity and the production of high-temperature process heat

[en] An overview of the operation of the Swiss nuclear power plants Beznau, Muehleberg, Goesgen and Leibstadt for December 1986 is given together with a retrospective view of 1986

[en] This is a revised and updated edition of 'Nuclear Fuel and Power, Capacity, Demand and Trade Prospects', first published in March 1984. It presents the results of an analysis of projections of effective nuclear power generating capacity in all countries during the remainder of this century, projections of nuclear power production, its fuel requirements and its relation to electricity demand in OECD countries during the same term and projections of indigenous and imported natural uranium supply in OECD countries up to 1995. The results are summarized in Part I. Detailed results and projections for OECD countries, the Third World and the CMEA (Europe) countries (the Soviet Union and the six East European members of the CMEA), are discussed in Parts II,III and IV. The methods are explained and results tabulated in the Appendices. It was published in April 1986 before the accident at the Chernobyl reactor. (UK)
