[en] It is now a quarter of a century since nuclear energy was introduced to the public. Its introduction was made in the most dramatic, but unfortunately in the most destructive way - through the use of a nuclear weapon. Since that introduction enormous strides have been made in developing the peaceful applications of this great and versatile force. Because these strides have always been overshadowed by the focusing of public attention on the military side of the atom, the public has never fully understood or appreciated the gains and status of the peaceful atom. This booklet is an attempt to correct, in some measure, this imbalance in public information and attitude. It is a compilation of remarks, and excerpts of remarks, that I have made in recent years in an effort to bring to the public the story of the remarkable benefits the peaceful atom has to offer man. This is a story that grows with the development and progress of the peaceful atom. It must be told so that we can learn to use the power of nuclear energy wisely and through this use help to build a world in which the military applications of the atom will never again be a threat to mankind
[en] The marketing possibilities of natural and treated woods are compared. A description is given of the advantages and disadvantages of these materials, together with the effects that improved quality might have on marketing prospects. Extensive reference tables illustrate the change in supply and demand over a number of years. (author)
[en] A close examination of the local supply and demand for fresh water is involved when considering a sea water desalination plant in a given region. This examination makes it possible in most cases to undertake a thorough study of the natural resources, resulting in the use of desalination being rejected. After confirming this fact by precise examples, the authors consider that the preliminary study should be extended, taking into account the complementary character of natural resources and desalination systems: contribution to peak demand, contribution to base demand. This analysis results in a classification of the main user regions according to certain economic criteria defining their suitability for the use of desalination processes. (author)
[fr]Envisager une installation d'eau de mer dans une region donnee, entraine un examen attentif de l'offre et de la demande locale en eau douce. Cet examen permet de conduire dans la plupart des cas a une etude approfondie des ressources naturelles qui aboutit a ecarter le recours au dessalement. Apres avoir constate ce fait, par des exemples precis, les auteurs estiment que l'on doit pousser plus loin l'etude preliminaire en tenant compte de la complementarite entre les ressources naturelles et les systemes de dessalement: contribution a la demande de pointe, contribution a la demande de base. Cette analyse conduit a classer les regions utilisatrices essentielles selon certains criteres economiques definissant leur aptitude a l'utilisation des procedes de dessalement. (auteur)
[en] A map of Colombia, a country located in the northern part of South America, is shown. With an extension of almost 1.4 million square kilometers, most of its 19.0 million inhabitants; live in the central and western regions while almost half of the territory (the eastern plains) is still largely unsettled and undeveloped. Although the Colombian economy has been dependent mainly on agricultural products and the coffee production has been the primary, source of foreign currency, it is clear now that an industrialization process is beginning. The effects of each a process can already be measured in terms of improved standard of living and in a more steady monetary situation.
[en] Pakistan is one of the very few developing countries which have nuclear power plants actually under construction. The country has a unique geographical position in the sense that it consists of two provinces, namely East Pakistan and West Pakistan, which are physically separated by over 1000 miles of Indian territory. Because of the physical separation of the two provinces, the power systems and the development programmes in the two provinces are considered separately.
[en] The Agency's latest survey of power and research reactors in Member States shows that by the end of 1969 there will be 479 reactors operating. Of these, 105 are power reactors generating nearly 20 000 megawatts of electricity in 15 countries. The other 374 are for research, testing and training purposes in 48 countries. (author)
[en] Experience with experimental fast reactors and the construction of larger prototypes, though limited to few countries, is supported by research on specific aspects in a number of others. Examination of results at an Agency symposium in Monaco during March demonstrated confidence that these reactors will come into use after 1980, will lead to much cheaper generation of electricity, and to much greater economy in using the world's uranium resources.

[en] Dr. Sigvard Eklund, Director General of the IAEA, addressed the 49th Session of the Economic and Social Council of the United Nations, in Geneva, on 9 July. In his speech he drew attention to 'a major event . . . which has had an immediate effect on the work of the IAEA and which could, in the future, affect the whole structure of international relations': the coming into force of the Treaty on the Non-Proliferation of Nuclear Weapons earlier this year.

[en] Prospects for the development of small and medium power reactors were reviewed at a symposium attended by more than 150 participants from 35 countries and five international organizations, held in Oslo in mid-October. Discussion centred on the current technical and economic status of reactors having an output of more than about 500 MWe, which might find application in the comparatively small electricity supply grids which are generally associated with areas where industrialization is not very far advanced.

[en] 2 December 1942, just twenty-five years ago, is the date most often proclaimed as marking the beginning of the atomic age. On that day Enrico Fermi's atomic 'pile' went critical - man had achieved the first self-sustained nuclear chain reaction and controlled it. This achievement is an outstanding example of how modern science can work. It had been predicted in theory, calculated in advance and finally realised through the work of large teams of scientists, headed by some of the most imaginative personalities of our century. The military aspects of man-made nuclear chain reaction still dominate our world today. However, within this quarter of a century, nuclear energy has also become significant as a source of power for peaceful purposes. By the end of another quarter of a century it will, according to the best forecasts we can make today, produce a major part of the electricity in the world. The control of nuclear fission was initiated by Fermi and his collaborators. It had a tremendous impact on politics, on concepts of warfare and finally on scientific progress for man's welfare. Fifteen years afterwards the International Atomic Energy Agency was created to promote the peaceful uses of the new technology and to assist in winning the advantages it offered for improving health and prosperity. Another of its great objects is to ensure, as far as possible, that nuclear materials intended for peaceful purposes shall not be diverted to military ends. The hope of the world must be that this, one day, will include all nuclear materials
