[en] When will atomic power start to play its part in earnest; that is, when will a significant fraction of new power plants be based on nuclear systems? This is in my opinion the key question today. It is still early to try to give a definitive answer, but recent developments in the nuclear power field now make it still more urgent to give this question thorough consideration. In order to do so it is necessary to make a survey of the need for power as it exists now and as it is likely to develop in the future; one must also find out what possibilities exist to meet this demand from known energy reserves or such reserves as can be expected to be available in the future. Such a survey made on a global basis will give a balanced picture, but the conclusions obtained in such a way cannot, of course, be applied to individual and local situations. If it were to be proved that our reserves will be insufficient, nuclear power would clearly seem to have an important role in meeting the need, but it is at the same time of the utmost importance to find out if energy reserves hidden in the world's resources of uranium and of thorium are adequate or if technological development can make them so
[en] A nuclear power expert of the International Atomic Energy Agency, who was sent to El Salvador at the request of that country's Government, has recommended that the possibility of using nuclear energy as a competitive source of power generation in El Salvador should be kept under review and given a more serious study within the next few years. The report submitted by the expert after his mission to El Salvador contains a preliminary assessment of the prospects of nuclear power in the country. His main findings are presented
General report on the behalf of the Commission for Finance, Budgetary Control and Nation's economic accounts, about the finance bill project for 1963 (part 2 - Service means and special arrangements), adopted by the National Assembly - Nr 43. Opinion presented on the behalf of the Commission for Economic Affairs and Planning, on the finance bill project for 1963 (part 2 - Service means and special arrangements), adopted by the National Assembly - Nr 44
[en] This document comprises two reports. The first one states comments and critics made by the Senate Commission on the content of topics of the finance bill project for 1963 depending on the Prime Minister Services (overseas services, education, so on.) and more particularly atomic energy: expenses related to the Pierrelatte plant, to submarine propulsion, to CEA operation and activities (with an inventory of radio-elements), to the CERN (European Research Centre for Nuclear Physics) development and operation, to EURATOM activities, to the operated nuclear reactors. The second report focuses on atomic and nuclear issues. The author briefly presents the nuclear fuel production, and the status of the nuclear electric power production from five nuclear plants. He discusses the development perspectives of nuclear power production, presents and comments the activities of different nuclear research centres (Saclay, Fontenay-aux-Roses, Grenoble, Cadarache), proposes an overview of nuclear power production in England, in the USA and in the USSR. He finally comments credits awarded to the CEA, their level, their usage, the part used to build EDF plants, and those coming from the Army budget, and also the financing of the Pierrelatte plant
[en] The economic advantage of electricity-generating nuclear stations decreases when their size decreases. However, when a counter-pressure turbine is joined on to a reactor and the residual heat can be properly used, it can be shown that fairly low capacity nuclear equipment may compete with conventional equipment under certain realistic enough conditions. The aim of this paper is to define these special conditions under which nuclear energy can be profitable. They are connected with the location and the general economic environment of the station, the pattern of the electricity and heat demands it must meet, the level of fuel and specific capital costs, nuclear and conventional. These conditions entail certain technical and economic specifications for the reactors used in this way otherwise they are unlikely to be competitive. In addition, these results are referred to the potential steam and electricity market, which leads us to examine certain uses for the heat generated by double purpose power stations; for example, to supply combined industrial plants, various types of town heating and for removal of salt from sea water.

[fr]L'interet economique de centrales nucleaires productrices d'electricite decroit lorsque la puissance decroit. Cependant, lorsqu'on associe une turbine a contrepression a un reacteur et qu'il est possible d'utiliser dans de bonnes conditions la chaleur residuelle, on peut montrer que dans certaines conditions assez realistes, des equipements nucleaires d'une puissance unitaire peu elevee peuvent etre competitifs avec des equipements conventionnels. Cette communication a donc pour but de mettre en evidence quelles sont ces conditions particulieres de rentabilite de l'energie nucleaire. Elles sont liees a la localisation de la centrale et a son contexte economique general, a la structure de la demande d'energie electrique et thermique a laquelle elle doit satisfaire, au niveau des couts des combustibles et des investissements specifiques nucleaires et classiques. Ces conditions de rentabilite conduisent a admettre pour les reacteurs ainsi utilises certaines caracteristiques techniques et economiques hors desquelles la competition est improbable. On situe, d'autre part, ces resultats par rapport au marche potentiel de la vapeur et de l'electricite et on est ainsi conduit a examiner certaines utilisations de la chaleur des centrales mixtes telles que l'alimentation de complexes industriels, de divers types de chauffage urbain ou du dessalement des eaux de mer.

[en] A report on nuclear power prospects in the Philippines, recently published by IAEA, analyzes the prospects for installing late in the 1960's a relatively large nuclear power plant in the electric power grid which serves a major part of the Island of Luzon. It concludes that such a plant might be economically competitive over its lifetime with a conventional power plant of the same size. Accordingly, the report recommends steps which the Philippine authorities might take if they wish to pursue the matter further
[en] On the occasion of the 20th anniversary of the conducting of the first self-sustaining nuclear chain reaction and following development of nuclear reactors, the article reviews the work and scientific development behind this achievement. The impact of atomic energy on economics, benefits of nuclear reactors for electricity production and the by-product - radio isotopes, used in different areas such as industry, medicine, agriculture etc. are pointed out
[en] As a working method for determination of changes in molecular mass that may occur by irradiation (pyrolytic-radiolytic decomposition) of polyphenyl reactor coolants, a cryoscopic technique has been developed which associated the basic simplicity of Beckman's method with some experimental refinements taken out of the equilibrium methods. A total of 18 runs were made on samples of napthalene, biphenyl, and the commercial mixtures OM-2 (Progil) and Santowax-R (Monsanto), with an average deviation from the theoretical molecular mass of 0.6%.

[en] Four recent estimates of the fossil fuel resources in the United States are used in the Report on Civilian Nuclear Power. They are not entirely independent estimates and, in particular, three of the estimates of coal resources have as their basis the data in 'Coal Reserves of the United States - A Progress Report, January 1, 1960,' Geological Survey Bulletin 1136. The total energy content of the various fossil fuel resources remaining in the United States as given by these estimates has been summarized.
[en] The basic circumstances which stimulated Finland's interest in nuclear power are summarized in the report as follows: 'In Finland the main power resource has been, and still is, water power. It is clear, however, that the hydro potential is insufficient to cover the increasing consumption over a long period of time. Already about one half of this potential has been exploited. Thus the country will necessarily have to consider the utilization of thermal power to an increasingly large extent. There is no indigenous coal or oil. For this reason it has become necessary to investigate realistically the possibilities offered by nuclear power'
