More TECHNICAL BRIEFS. Hie negative side uf civilian nuclear power development holds (1) that coal is so abundant in this country we should let other nations where coal is scarce develop the technology (or use of the new nuclear fuel, (2) that a strong civilian nuclear power program would seriously reduce the military effort in this- field and, because of the declassi fication necessary, would compromise security. And lost but net least, such a program would cost millions ol dollars. Summarising the eituation favoring nuclear power development now, there is the prestige value to be gained, the matter of foreign competition, the op timistic views on the current economics of nuclear power, by-product military benefits, assuring maximum return from our military investment in the atom, provisions of the Atomic Energy Act permitting civilian development and the present enthusiasm in industry to join with government in the search for com mercial nuclear power. APC Paper, no number. economic evaluation of the Industrial Ue of Atomic Energy. By ITalker L Ciller. The Detroit Edison Co. Although many Industrial uses of atomio energy ere contemplated,' the practical uses, for the present, seem to be (1) production of radioactive Iso topes for numerous purposes, and (2) use of the vast amount of heal energy released by the fission of atoms of ura nium (U-233 and U-235) and plutonium (Pu-239). This hest will be used for production of steam which in turn can be used for generation of electric power or for other industrial purposes. For the sake of simplicity, this discussion will concern chiefly the generation of eleetric power. The questions first asked about the use of atomic energy for the generation of electric power are (1) Is it physically possible at this lime? and (2) how much will it cost? The first of these questions has keen answered affirmatively many times. .Or Walter H Zinn, in a paper presented at this meeting has told us of the exceed ingly difficult problems which are in volved and indicated that ways of meet ing these problems can be found. He has also told us of the experimental breeder reactor at Arco, Idaho where the generation of comparatively' email amounts of electricity using the heat of nuclear fission has actually been accom plished. The second question, how much will It cost, is much more perplexing. It involves many different problems and unfortunately cannot be answered spe- cifically at this time. The best we can do is to make a rather broad economic evaluation of several aspects of tbe de velopment to show why atomio energy is of such vital importance to our coun try and to the world, and to point out areas in which energy derived from nuclear fission will be of great economic value. The aspects to be considered in clude (1) the potential fuel resources of the world, end their importance to civ ilisation, (2) die utilisation of our nat urally fissionable and fertile materials, and (3) the justifiable costa of heat power reactors. In undertaking an economic evalua tion of this kind we should bring Into foeus the goals which we ore striving to achieve. The electric power industry has long balanced costa in the effort to provide power to the ultimate consumers in the most economical manner, h has weighed the coat of producing power in thermal plants located at mine mouths os compared with location near the load centers. It has made studies of the over all costs of supplying power from ther mal plants as compared with hydro electric plant's. And from these studies decisions hove been made conceroij>| the methods of supplying electricity our power systems and to the ultlmifr customers at the lowest possible cosuj consistent with good service standard^ Atomic onergy provides us with'l? new source of fuel. It Is attractive $ us because we hope to be able to uiinjjj1 it to produce electric power at a ecu less than that incurred with.the preseal U| conventional (ue)s or with the energy & (ailing water--hydro-electric generation/ Unless we can accomplish this goifi electric power systems or those Indip tries that provide self-generation canatf justify the large scale uso of atosa fuels for power generation. Consumer? cannot be expected to pay a higher cefr for electricity simply because it Is prg duced by using atomic fuels. It Is qj derttood, of course, iliat all proper; credits and debits for by-produets pro duced in the operation of nuclear rtsS tore must be included in determintifl real costs of power produced with aloa&; fuels. The goals, therefore, are to develop practical commercial installations whlcK will produce electric power at as low on lowfcr costs than present day power ga^ TO OBTAIN COMPLETE TEXT Material for these abstracts comes from the following sources unless otherwise stated.
