Abstract

Generally the volumes of low- and intermediate-level radioactive wastes produced at chemical processing sites are so great as to make permanent storage prohibitively costly. In many instances chemical treatment may provide sufficient decontamination to allow the discharge of these effluents to surface streams or estuaries. However, in some circumstances such methods are costly and either do not make possible adequate decontamination, or result in excessively large volumes of semi-solid wastes that must be permanently stored. It is believed that in such a situation the deep underlying formations of the earth may constitute a safe and economic waste-disposal resource. In sandstone formations large volumes of waste may be stored with a high degree of containment integrity. Both the interstitial voids and ion-exchange properties serve to make available a great storage capacity. The disposal system employing deep formations of the earth is conceived to consist of a pattern of injection wells for introducing the waste, and of relief wells which serve to reduce well-head pressures, permit monitoring, and direct the flow in such a manner as to make maximum use of the formation. Information needed for the design of such a system includes data on the dispersion or short-circuiting properties of the  More>>

It is believed that in such a situation the deep underlying formations of the earth may constitute a safe and economic waste-disposal resource. In sandstone formations large volumes of waste may be stored with a high degree of containment integrity. Both the interstitial voids and ion-exchange properties serve to make available a great storage capacity. The disposal system employing deep formations of the earth is conceived to consist of a pattern of injection wells for introducing the waste, and of relief wells which serve to reduce well-head pressures, permit monitoring, and direct the flow in such a manner as to make maximum use of the formation. Information needed for the design of such a system includes data on the dispersion or short-circuiting properties of the formations, ion-exchange characteristics of the media, and the chemical and radiochemical properties of the waste. A two-well prototype injection system has been in operation for two years at the Engineering Field Station of the University of California. (author) [French] En general, les dechets de faible ou moyenne activite produits dans les usines de traitement chimique atteignent un volume tel que le cout de leur entreposage permanent est prohibitif. Dans plusieurs cas, un traitement chimique peut produire une decontamination suffisante pour que ces effluents puissent etre jetes dans des cours d'eau et des estuaires. Dans certaines circonstances, cependant, ces methodes sont onereuses ; en outre, ou bien elles ne permettent pas une decontamination suffisante, ou bien elles donnent de grandes quantites de dechets semi-solides qui doivent etre entreposes d'une facon permanente. On croit qu'en pareils cas les dechets peuvent etre enfouis d'une maniere sure et a peu de frais dans les profondeurs des formations sous-jacentes du sol. De grandes quantites de dechets peuvent etre entreposees avec une tres forte probabilite d'isolement parfait dans les formations greseuses. Les vides interstitiels et les proprietes d'echange d'ions permettent de disposer d'une grande capacite d'entreposage. Les installations d'elimination qui permettent d'utiliser les formations profondes du sol comprennent des puits d'injection par lesquels on introduit les dechets et des puits de surete qui servent a reduire la pression a l'orifice des puits, a exercer un controle radiologique des operations et a diriger les effluents de maniere a utiliser la formation au maximum. Pour etablir le projet d'une telle installation, on a besoin de renseignements comprenant des donnees sur les proprietes de dispersion de la formation, les caracteristiques d'echange d'ions de la couche et les proprietes chimiques et radiochimiques des dechets. Le prototype d'une installation d'injection a deux puits fonctionne depuis deux ans a l'Engineering Field Station de l'Universite. (author) [Spanish] Por lo comun, el volumen de los desechos radiactivos de actividad baja e intermedia producidos en las instalaciones de tratamiento quimico es tan considerable que el coste de su almacenamiento permanente resulta prohibitivo. En muchos casos el tratamiento quimico permite alcanzar un grado de descontaminacion suficiente para permitir la evacuacion de los efluentes en estuarios o corrientes de agua superficiales. No obstante, en determinadas circunstancias estos metodos son demasiado costosos, y no permiten lograr un grado suficiente de descontaminacion o dan lugar a la formacion de enormes cantidades de desechos en estado semi-solido que han de almacenarse de modo permanente. Se estima que en tales casos las formaciones geologicas profundas pueden constituir un lugar de evacuacion satisfactorio desde el punto de vista de la seguridad y de la economia. En las formaciones de arenisca resulta posible acumular grandes cantidades de desechos con un alto grado de estabilidad del confinamiento. Merced a sus cavidades intersticiales y caracteristicas de intercambio ionico, esas formaciones suelen poseer una capacidad de almacenamiento muy considerable. En principio, el sistema de evacuacion que utiliza las formaciones geologicas profundas ha de consistir en un conjunto de pozos de inyeccion por los que se introducen los desechos, y de pozos de compensacion que sirven para reducir la presion en la boca de los pozos, medir la radiactividad y dirigir el flujo de tal modo que se aproveche al maximo la capacidad de almacenamiento de la formacion. Entre los datos necesarios para proyectar un sistema de este tipo figuran las propiedades de dispersion de la formacion sus caracteristicas de intercambio ionico y las propiedades quimicas y radioquimicas de los desechos. En el Centro tecnologico experimental de la Universidad de California viene funcionando desde hace dos anos un sistema piloto de dos pozos con una capa acuifera. (author) [Russian] Obychno na predprijatijah himicheskoj obrabatyvajushhej promyshlennosti radioaktivnye othody s nizkim i srednim urovnjami aktivnosti imejut mesto v takom bol'shom kolichestve, chto ih hranenie v techenie dolgogo vremeni nerentabel'no. Vo mnogih sluchajah himicheskaja obrabotka othodov mozhet obespechit' dostatochnuju ih dezaktivizaciju dlja otvoda othodov v reki ili morja. Odnako v nekotoryh sluchajah takie metody trebujut zatrat i libo ne obespechivajut dostatochnoj dezaktivacii, libo privodjat v itoge k obrazovaniju chrezvychajno bol'shogo kolichestva polutverdyh othodov, dlja kotoryh neobhodimo obespechit' stacionarnoe hranenie. Predpolagaetsja, chto v takom sluchae glubokie geologicheskie obrazovanija mogut javit'sja mestami dlja bezopasnogo i renta- bil'nogo zahoronenija othodov. V obrazovanijah peschanika mozhno hranit' v bol'shom kolichestve othody s vysokoj aktivnost'ju. Kak obshhee svojstvo zhidkostej, vsegda stremjashhihsja zapolnit' pustoty, tak i osobennosti ionnogo obmena v othodah blagoprijatstvujut shirokomu ispol'zovaniju takih emkostej dlja hranenija othodov. Sistema udalenija othodov, v kotoroj ispol'zujutsja glubokie geologicheskie obrazovanija, kak schitajut, sostoit iz sistemy vpusknyh skvazhin dlja vvedenija othodov i razgruzochnyh skvazhin, kotorye sluzhat dlja kontrolja i regulirovanija potoka othodov s cel'ju obespechit' naibolee racional'noe ispol'zovanie emkosti. Nuzhnye svedenija dlja proektirovki takoj sistemy vkljuchajut dannye po dispersionnym svojstvam, obrazovaniju dannoj geologicheskoj formacii, osobennostjam ionnogo obmena sredy, a takzhe po himicheskim i radiohimicheskim svojstvam othodov. V tehnicheskoj polevoj stancii universiteta v techenie dvuh let dejstvuet opytnaja dvuhskvazhennaja vpusknaja sistema. (author)}
