[en] This paper attempts to make a fair comparison of the financial cost of producing and supplying most of the relevant forms of energy of fossil fuels, nuclear power and renewable energy sources. The role of cost in making the choice between the variety and abundance of energy supplies that are available is described and some of the main considerations and uncertainties to be taken into account in comparing the technical cost of energy projects, including the need to protect the environment are examined. Comparative cost estimates are presented on a uniform and consistent basis in a number of charts and the background to these costs and the basis on which they have been estimated is described.

[en] The purpose of this paper is to examine some of the systems and sub-systems involved in so-called ''conventional'' e⁺e^- linear colliders and to study how their design affects the overall cost of these machines. There are presently a total of at least six 500 GeV c. of m. linear collider projects under study in the world. Aside from TESLA (superconducting linac at 1.3 GHz) and CLIC (two-beam accelerator with main linac at 30GHz), the other four proposed e⁺e^- linear colliders can be considered ''conventional'' in that their main linacs use the proven technique of driving room temperature accelerator sections with pulsed klystrons and modulators. The centrally distinguishing feature between these projects is their main linac rf frequency: 3 GHz for the DESY machine, 11.424 GHz for the SLAC and JLC machines, and 14 GHz for the VLEPP machine. The other systems, namely the electron and positron sources, preaccelerators, compressors, damping rings and final foci, are fairly similar from project to project. Probably more than 80% of the cost of these linear colliders will be incurred in the two main linacs facing each other and it is therefore in their design and construction that major savings or extra costs may be found

[en] In the future a transfer from the fossil fuel-based economy to hydrogen-based economy is expected. Therefore the development of systems for efficient H_2 production becomes important. The several conventional methods of mass-scale (or central) H_2 production (methane, natural gas and higher hydrocarbons reforming, coal gasification reforming) are well developed and their costs of H_2 production are acceptable. However, due to the H_2 transport and storage problems the small-scale (distributed) technologies for H_2 production are demanded. However, these new technologies have to meet the requirement of producing H_2 at a production cost of $(1-2)/kg(H_2) (or 60 g(H_2)/kWh) by 2020 (the U.S. Department of Energy's target). Recently several plasma methods have been proposed for the small-scale H_2 production. The most promising plasmas for this purpose seems to be those generated by gliding, plasmatron and nozzle arcs, and microwave discharges. In this paper plasma methods proposed for H_2 production are briefly described and critically evaluated from the view point of H_2 production efficiency. The paper is aiming at answering a question if any plasma method for the small-scale H_2 production approaches such challenges as the production energy yield of 60 g(H_2)/kWh, high production rate, high reliability and low investment cost.

[en] The purpose of this work is to show how to predict the variance and the mean of a Monte-Carlo estimator by a previous deterministic calculation. When the time spent per particle can be also predicted, it is then possible to get the cost of the MC calculation before its execution. The previous works of T. Booth and R.J. Juzaitis are the theoretical basis of this study of MC errors. We shall give numerical results in infinite slab and finite cylinder geometries

[en] Many different estimates for the cost of decommissioning nuclear power plants have been published. This book, aimed at the general reader, analyzes reasons why the published estimates for decommissioning vary so widely, and examines to what extent various political, institutional, technical, and economic factors could explain the variation

[en] The Fast Flux Test Facility (FFTF) is a government-owned, 400-MW(thermal), sodium-cooled test reactor operated by Westinghouse Hanford Company. The reactor is shut down and is undergoing a transition to a long-term surveillance and maintenance state. The mission strategy for the FFTF transition project is to place the FFTF in a radiologically and industrially safe condition, completing the transition phase activities as soon as possible to drive down the current annual surveillance and maintenance costs from approximately $26 million/yr to roughly $1.5 million/yr. The effort to establish the shutdown and transition costs for this 7-yr, $260 million activity is a first of a kind for the U.S. Department of Energy (DOE)

[en] Eric Besson, former minister of Industry, Energy and the Digital Economy, asked a committee to analyze the various possibilities for France's energy policy in 2030 and beyond. The conclusions and recommendations are presented herein. With respect to the supply of electricity, this committee worked on four scenarios: a) maintaining the existing park of nuclear plants; b) accelerating the passage to the third or even fourth generation of nuclear reactors, c) gradually reducing the share of nuclear power; and d) closing down all nuclear power stations. 2 options have been examined for the d scenario: the substitution of nuclear energy by renewable energies (d1) and its substitution by fossil energies (d2). Different aspects have been examined: the electricity cost, CO₂ releases, jobs, trade balance and security of energy supply. For instance the cost of the electric power produced by the 4 scenarios a, b, c, and d have been estimated: -) between 60 and 73 euros/MWh for scenario b, -) between 52 and 59 euros/MWh for scenario a, -) between 69 and 79 euros/MWh for scenario c, -) between 92 and 102 euros/MWh for scenario d1, and -) between 80 and 89 euros/MWh for scenario d2. Moreover 8 recommendations have been proposed by the committee, the first 2 ones are: -) making energy saving and energy efficiency a national public priority, and -) decommissioning reactors only on safety concerns, not on political issues
