Abstract

The radioisotope power programme of the US Atomic Energy Commission has brought forth a whole new technology of the use of radioisotopes as energy sources in electric power generators. Radioisotope power systems are particularly suited for remote applications where long-lived, compact, reliable power is needed. Able to perform satisfactorily under extreme environmental conditions of temperature, sunlight and electromagnetic radiations, these ''atomic batteries'' are attractive power sources for remote data collecting devices, monitoring systems, satellites and other space missions. Radioisotopes used as fuels generally are either alpha or beta emitters. Alpha emitters are the preferable fuels but are more expensive and less available than beta fuels and are generally reserved for space applications. Beta fuels separated from reactor fission wastes are being used exclusively in land and sea applications at the present. It can be expected, however, that beta emitters such as stiontium-90 eventually will be used in space. Development work is being carried out on generators which will use mixed fission products as fuel. This fuel will be less expensive than the pure radioisotopes since the costs of isotope separation and purification are eliminated. Prototype thermoelectric generators, fuelled with strontium-90 and caesium-137, are now in operation or being developed for  More>>

A plutonium-238 thermoelectric generator is in orbit operating as electric power source in a US Navy TRANSIT satellite. Generators are under development for use on US National Aeronautics and Space Administration missions. The large quantities of radioactivity involved in radioisotope power sources require that special attention be given to safety aspects of the units. Rigid safety requirements have been established and extensive tests have been conducted to insure that these systems can be employed without creating undue hazards. (author) [French] Le programme de production d'energie au moyen des radioisotopes, execute par la Commission de l'energie atomique des Etats-Unis, a donne naissance a toute une technologie nouvelle de l'emploi des radioisotopes comme source d'energie dans des generateurs. Les sources d'energie utilisant des radioisotopes conviennent particulierement pour les applications a distance, qui exigent des alimentations de longue duree, de faibles dimensions et de fonctionnement sur. Ces ''batteries nucleaires'', qui peuvent fonctionner de maniere satisfaisante dans des conditions extremes de temperature et d'exposition aux rayons solaires et aux rayonnements electromagnetiques, constituent des sources d'energie interessantes pour differents types d'engins telecommandes tels que ceux qui sont destines a recueillir des renseignements ou a assurer une surveillance ainsi que les satellites et autres vehicules spatiaux. Les radioisotopes utilises comme sources d'energie sont generalement des emetteuis alpha ou beta. Les emetteurs alpha sont preferables, mais ils sont plus couteux et plus rares et on les reserve generalement pour les applications spatiales. A l'heure actuelle les emetteurs beta, obtenus par separation des dechets de la fission nucleaire, sont utilises exclusivement dans les engins terrestres et marins. On peut neanmoins prevoir que des emetteurs beta, comme le strontium-90, seront eventuellement utilises dans l'espace. On fait actuellement des recherches sur des generateurs qui utiliseront comme sources des melanges de produits de fission. Ces sources seront d'un prix de revient moins eleve qile les radioisotopes purs car les couts de la separation et de la purification seront supprimes. Des prototypes de generateurs thermoelectriques, utilisant le strontium-90 et le cesium-137 comme sources, fonctionnent actuellement ou sont mis au point dans des stations meteorologiques, des engins de balisage et des appareils pour la survellance des profondeurs marines. Le satellite TRANSIT, place sur orbite par la Marine americaine, est equipe d'un generateur thermoelectrique au plutonium-238 comme source d'energie electrique. Des generateurs sont a l'etude pour les projets spatiaux du Bureau de l'Aeronautique et de l'Administration de l'espace americains. En raison des grandes quantites de radioactivite que comportent les sources d'energie utilisant des radioisotopes, il faut accorder une grande attention a la securite de ces appareils. Pour s'assurer que l'on peut les utiliser sans creer de risques inutiles, on a etabli des normes de securite rigoureuses et procede a des essais tres pousses. (author) [Spanish] El programa de la Comision de Energia Atomica de los Estados Unidos en materia de energia electrica generada por radioisotopos ha dado origen a toda una nueva tecnologia cuyo objeto es el empleo de radioisotopos como fuentes de energia en los generadores de electricidad. Las fuentes radioisotopicas se prestan en particular para aplicaciones a distancia en las que se necesita una fuente de energia duradera, poco voluminosa y de funcionamiento seguro. Capaces de funcionar satisfactoriamente en las condiciones mas extremas de temperatura y exposicion a la luz solar y radiaciones electromagneticas, estas ''baterias nucleares'' constituyen fuentes interesantes de energia para dispositivos de acopio de datos controlados a distancia, sistemas de vigilancia, satelites y otros vehiculos espaciales. Los radioisotopos utilizados como fuente de energia son habitualmente emisores alfa o beta. Los emisores alfa son preferibles, pero tambien mas caros y menos abundantes que los emisores beta y se reservan por lo general para usos espaciales. En la actualidad los emisores beta obtenidos de los productos de fision procedentes de los reactores se utilizan exclusivamente para aplicaciones terrestres y maritimas. No obstante, es de esperar que con el transcurso del tiempo los emisores beta tales como el estroncio-90 se emplearan en el espacio. Se estan realizando investigaciones con generadores alimentados por mezclas de productos de fision. Estas seran menos costosas que los radioisotopos puros, pues se suprimen los gastos de separacion y purificacion de isotopos. En la actualidad funcionan o estan a punto de funcionar generadores termoelectricos prototipo, alimentados con estroncio-90 y cesio-137, en estaciones meteorologicas, dispositivos auxiliares de navegacion y aparatos de vigilancia de las profundidades del mar. En el espacio funcionan generadores termoelectricos de plutonio-238 como fuentes de energia electrica del satelite TRANSIT de la Marina de los Estados Unidos. Se estan construyendo asimismo generadores para los proyectos espaciales de la National Aeronautics and Space Administration de dicho pais. La elevada radiactividad inherente a las fuentes radioisotopicas de energia exige que se preste especial atencion a la seguridad de las mismas. Se han establecido rigurosas normas de proteccion y se han ejecutado ensayos muy avanzados para poder emplear estos dispositivos sin originar riesgos inaceptables. (author) [Russian] Programma ispol'zovaniya radioaktivnykh izotopov v kachestve ehnergeticheskogo syr'ya, razrabotannaya Komissiej po atomnoj ehnergii SSHA, privela k sozdaniyu sovershenno novoj tekhnologii primeneniya radioizotopov v kachestve istochnikov ehnergii v generatorakh ehlektroehnergii. Sistema radioizotopnykh ehnergeticheskikh stantsij osobenno nuzhna tam, gde vvidu krajnej otdalennosti trebuyutsya dolgovechnye, nadezhnye i malogabaritnye silovye ustanovki. Sposobnye udovletvoritel'no funktsionirovat' v tyazhelykh usloviyakh, naprimer pri dejstvii temperatur, solnechnogo sveta i ehlektromagnitnogo izlucheniya, takie ''atomnye batarei'' yavlyayutsya zamanchivymi istochnikami ehnergii dlya ustanovok, sobirayushchikh informatsiyu na rasstoyanii, dlya upravlyayushchikh sistem, dlya iskustvennykh sputnikov i drugikh kosmicheskikh ob{sup e}ktov. Radioizotopy, primenyayushchiesya v kachestve goryuchego, obychno ispuskayut al'fa- ili beta-luchi. Al'fa-izluchateli kak toplivo predstavlyayut bol'shuyu tsennost', no oni stoyat doroge i v to zhe vremya menee dostupny, chem beta-izluchateli, poehtomu ikh, kak pravilo, ispol'zuyut dlya kosmicheskikh zadach. Beta-goryuchee, vydelennoe iz otkhodov reaktora, v nastoyashchee vremya primenyaetsya isklyuchitel'no dlya nazemnykh ili morskikh tselej. Odnako sleduet ozhidat', chto takie beta-izluchateli, kak strontsij-90, v kontse kontsov budut primenyat'sya i v kosmose. V nastoyashchee vremya vedutsya issledovatel'skie raboty s generatorami, v kotorykh v kachestve goryuchego budut primenyat' smeshannye produkty deleniya. Ehto goryuchee budet deshevle, chem chistye radioizotopy, poskol'ku sokratyatsya zatraty na razdelenie izotopov i na ikh ochistku. Prototipom termoehlektri- cheskikh generatorov, pitaemykh strontsiem-90 i tseziem-137, yavlyayutsya uzhe funktsionirujte ili razrabatyvaemye generatory na meteorologicheskikh stantsiyakh, v navigatsii i v glubokovodnykh ustrojstvakh obnaruzheniya. Termoehlektricheskim generatorom, rabotayushchim na plutonii-238, osnashchen iskustvennyj sputnik ''Tranzit'', razrabotannyj voennomorskim vedomstvom SSHA. Razrabatyvayutsya generatory dlya ispol'zovaniya v kosmose Upravleniem po natsional'noj aehronavtike i issledovaniyu kosmicheskogo prostranstva. Vysokaya aktivnost' radioizotopnykh istochnikov ehnergii trebuet, chtoby voprosam bezopasnosti bylo udeleno osoboe vnimanie. Sleduet ustanovit' strogij kontrol' za soblyudeniem tekhniki bezopasnosti i provesti ryad shirokikh ispytanij, chtoby udostoverit'sya, chto radioaktivnye sistemy mogut funktsionirovat', ne nanosya ushcherba okruzhayushchim.
