[en] The purpose of this paper is to indicate the vast gap in the utilisation of nuclear power between advanced and developing countries, identify some of the major problems encountered in the introduction of nuclear power into developing countries and suggest some possible approaches to overcome them.
[en] The Vulcain programme has been set up with the aim of developing a water reactor type specially designed to be attractive in the range of small and medium power outputs, especially in view of its application in developing countries. There is a market on economic grounds for small and medium size nuclear power stations whose specific investment cost is below a threshold. Extra-economic considerations may also justify the erection of small and medium size nuclear power stations. We believe that nuclear power stations of the Vulcain type are an interesting proposal for these markets.
[en] More than a million dollars has now been spent by the Agency on research contracts to aid work with radioisotopes in medicine. The object is to assist in making radioisotope techniques, as developed and elaborated in the technologically advanced countries, available to hospitals and medical research institutions in developing countries, where they can be applied to solve particular local or regional health problems
[en] In many developing countries there is a need to improve the food by increasing its protein content. The stimulation of the synthesis of proteins by the crops must be considered of primary importance in those countries. Different methods for determination of the available nitrogen and of the nitrogen uptake by plants can be defined: field, trials; plot methods; micro-plots; pot experiments; lysimeters; incubation of samples in the laboratory, and recurrent profile sampling. Advantages and disadvantages of all these methods are briefly discussed, considering whether the main transformations of nitrogen in soil and the nitrogen status could be characterized applying these methods. The most important nitrogen transformations in soil may be summed up as follows: 1. Leaching by rain, thereby distinguishing ammonia- and nitrate-nitrogen; 2. Volatilization (denitrification, disintegration of nitrites, evaporation, of NH3); 3. Fixation of NH4+, in expanding crystal-lattices of clay minerals. Finally, the situation in developing countries and in the industrialized, developed countries is compared, deriving some conclusions for the way of farming; to be recommended in connection with the nitrogen problems.

[en] The paper discusses the development of nuclear physics in developing countries, pointing out the difficulties of research in the future. A proposal for the formation of regional centres is put forward. Arguments justifying the formation of these regional centres are presented together with the suggestion that UNESCO and IAEA act as sponsors and financial supporters of the regional centres. The institutes in the developing countries could serve as a basis for such centres. Countries which are qualified and interested in having and using the facilities of the regional centres should also participate in the financing of them. (author)
[en] Nuclear power is now being accepted as a fully competitive source of electric power in large sized units in many industrialized countries. If we examine growth of nuclear capacity in recent years, we find that there has been a steady increase in unit sizes and this trend is likely to continue. Under these circumstances countries which are unable to use large plants may find it increasingly difficult to benefit from cheap nuclear power until their grids become extensive enough to absorb such large units. This paper examines the prospects of intermediate size power reactors (200 - 500 MW), by reviewing the problems associated with their availability and competitiveness and suggests how some of these problems could be met.
[en] Rapid progress has been made in a branch of medical work which uses radioactivity without involving the patient. Known as 'in vitro' - or test tube - procedures, they are valuable because of their simplicity and may be of great advantage in developing countries. This brief review is by Dr. H. Belcher, of the Division of Life Sciences. (author)
[en] The text of the Agreement between the Agency and the Government of Sweden relating to Co-operation in the Provision of Assistance to Developing Countries is reproduced in this document for the information of all Members. The Agreement entered into force on 18 January 1970 pursuant to Section 27 thereof.
[en] Recent developments, and especially the new and critical interest of developing countries, have helped to mark the turning of a page in the Agency's history. If the present situation in the economics of nuclear power does not change there is a danger that developing countries will lag further and further behind the advanced countries in its use. Shortage of resources impose a brake on Agency efforts to promote benefits of nuclear techniques, especially by technical assistance. These were some of the points made by Dr. Sigvard Eklund, the Director General, when he presented the Agency's annual report to the Economic and Social Council (ECOSOC) in July. (author)
