Abstract

The proposed use of cavities in salt formations as a disposal site for radioactive wastes is based upon : 1. Existence of salt for geologic time periods, 2. The impermeability of salt to the passage of water; 3. The widespread geographical distribution of salt; 4. The extremely large quantities of salt available; 5. The structural strength of salt; 6. The relatively high thermal conductivity of salt in comparison with other general geologic formations; 7. The possible recovery of valuable fission products in the wastes injected into the salt; 8. The relative ease of forming cavities in salt by mining, and the even greater ease and low cost of developing solution cavities in salt; and 9. The low seismicity in the areas of major salt deposits. Radioactive liquid wastes can be stored in cavities in natural salt formations if the structural properties of the salt are not adversely affected by chemical interaction, pressure, temperature, and radiation. Analytical studies show that it is possible to-store 2-year-old 10,000 MWD/T, 800 gal/ton waste in a sphere of 10 ft diameter without exceeding a temperature of 200 Degree-Sign F. Laboratory tests show that the structural properties and thermal conductivity of rock salt are not greatly  More>>

Analytical studies show that it is possible to-store 2-year-old 10,000 MWD/T, 800 gal/ton waste in a sphere of 10 ft diameter without exceeding a temperature of 200 Degree-Sign F. Laboratory tests show that the structural properties and thermal conductivity of rock salt are not greatly altered by high radiation doses, although high temperatures increase the creep rate for both irradiated and unirradiated samples. Chemical interaction of liquid wastes with salt produces chlorine and other chlorine compound gases, but the volumes are not excessive. The migration of nuclides through the salt and deformation of the cavity and chamber can only be studied in undisturbed salt in situ. One-fifth-scale models have been run in a bedded salt deposit in Hutchinson, Kansas, and full-scale field tests are in progress. (author) [French] L'emploi envisage des cavites des gisements de sel comme lieu d'evacuation des dechets radioactifs se-fonde sur les considerations suivantes: 1. L'existence du sel dans des formations correspondant a diverses periodes geologiques ; 2. L'impermeabilite du sel a l'ecoulement d'eau; 3. La vaste repartition geographique du sel; 4. Les enormes quantites de sel existantes ; 5. La solidite structurale du sel; 6. La conductivite thermique relativement elevee du sel par rapport a d'autres formations geologiques generales; 7. La recuperation eventuelle de precieux produits de fission dans les dechets injectes dans le sel; 8. La facilite relative d'obtenir des excavations dans le sel par voie d'extraction, ainsi que la facilite encore plus grande et le cout reduit de la preparation dans le sol de cavites par voie de solution; 9. La faible seismicite constatee dans les zones des principaux gisements de sel. Les dechets radioactifs liquides peuvent etre emmagasines dans les cavites des formations de sel naturel, a condition que les proprietes structurales/du sel ne soient pas defavorablement influencees par les interactions chimiques, la pression, la temperature et les rayonnements. Il ressort d'etudes analytiques qu'on peut emmagasiner 3.200 litres (800 gallons) par tonne de dechets d'uranium irradie a 10.000 MWj/t, vieux de deux ans, dans une sphere de 3 metres (dix pieds) de diametre sans depasser une temperature de 93 Degree-Sign C (200 Degree-Sign F). Des essais de laboratoire montrent que les proprietes structurales et la conductivite thermique du sel gemme ne sont pas sensiblement transformees par des doses de rayonnements intenses, bien que les temperatures elevees augmentent le taux de fluage des echantillons irradies et non irradies. Les interactions chimiques de dechets liquides avec du sel donnent naissance a du chlore et a des composes gazeux du chlore, mais les volumes n'en sont pas excessifs. Les migrations des nuclides a travers le sel ainsi que la deformation de la cavite ne peuvent etre etudiees que sur place dans le sel vierge. Des maquettes a l'echelle de 1/5 ont ete essayees a Hutchinson (Kansas) dans un gisement de sel; des essais d'une certaine importance sont actuellement en cours. (author) [Spanish] Las razones por las que se propone utilizar las cavidades en las formaciones salinas como lugar de evacuacion de desechos radiactivos son: 1. La gran antigueedad de los yacimientos de sal; 2. La impermeabilidad de la sal al agua; 3. La amplia distribucion geografica de los yacimientos salinos; 4. Las enormes cantidades de sal disponibles ; 5. La resistencia estructural de la sal; 6. La elevada conductividad termica de la sal comparada con la de otras formaciones geologicas; 7. La posibilidad de recuperar valiosos productos de fision de los desechos evacuados en formaciones salinas; 8. La relativa facilidad con que se puedan formar oquedades por excavacion del yacimiento y la facilidad aun mayor de formar cavidades a bajo coste por disolucion de la sal; 9. La escasez de sismos en las zonas donde existen grandes yacimientos de sal. Los desechos radiactivos liquidos pueden almacenarse en las cavidades de los yacimientos salinos naturales si las propiedades estructurales de la sal no resultan desfavorablemente afectadas por la interaccion quimica y los efectos de la presion, temperatura y radiacion. Los estudios analiticos demuestran que luego de dejarlos enfriar durante dos anos es posible almacenar los desechos resultantes del tratamiento de uranio irradiado a 10,000 MW dia per tonelada y formados a razon de 800 galones/tonelada en una esfera de 10 pies de diametro sin que la temperatura exceda de 200 Degree-Sign F. Los ensayos de laboratorio demuestran que las propiedades estructurales y la conductividad termica de la sal gema no resultan apreciablemente alteradas por grandes dosis de radiacion, aunque las temperaturas elevadas aumentan el indico de fluencia tanto en las muestras irradiadas como en las no irradiadas. Por la accion de los desechos liquidos sobre la sal se forman volumenes moderados de cloro y otros gases clorados. La migracion de los nuclidos a traves de la masa salina y la deformacion de las cavidades pueden solo estudiarse en las formaciones salinas inalteradas. En un yacimiento estratificado de sal situado en Hutchinson, Kansas, se han hecho experimentos con modelos a escala 1:5 y se estan realizando pruebas sobre el terreno a escala 1:1. (author) [Russian] Predlagaemoe ispol'zovanie polostej soljanyh zalezhej v kachestve mest dlja udalenija radioaktivnyh othodov osnovyvaetsja na: 1. Sushhestvovanii soli v techenie geologicheskih vekov, 2. Vodonepronicaemosti soli, 3. Shirokom geologicheskom rasprostranenii soli, 4. Chrezvychajno bol'shih kolichestvah imejushhejsja soli, 5. Strukturnoj prochnosti soli, 6. Sravnitel'no vysokoj teploprovodnosti soli po sravneniju s drugimi geologicheskimi obrazovanijami obshhek haraktera, 7.

Sravnitel'no legkom sozdanii polostej v soli putem vyemki porody i eshhe bol'shej legkosti i nizkih zatratah na razrabotku v soli rastvornyh polostej, 9. Nizkoj sejsmichnosti v rajonah glavnyh soljanyh zalezhej. Zhidkie radioaktivnye othody mogut hranit'sja v polostjah, nahodjashhihsja . v zalezhah prirodnoj soli, esli strukturnye svojstva soli ne narusheny himicheskim vzaimodejstviem, davleniem, temperaturoj ili radiaciej. Analiticheskie issledovanija pokazyvajut, chto mozhno hranit' 800 gal/tonn dvuhgodichnyh othodov na 10000 MWD/T v sfere diametrom 10 futov, esli temperatura ne. prevyshaet 200 Degree-Sign po Farengejtu. Laboratornye ispytanija pokazyvajut, chto strukturnye svojstva i teploprovodnost' gornoj soli ne izmenjajutsja v znachitel'noj stepeni pod vozdejstviem vysokih doz radiacii, hotja vysokie temperatury uvelichivajut stepen' polzuchesti kak dlja obluchennyh, tak i dlja neobluchennyh obrazcov. Himicheskoe vzaimodejstvie zhidkih othodov s sol'ju daet hlor i drugie hloristye gazoobraznye soedinenija, no ih kolichestvo ne veliko. Migracija nuklidov v soli i deformacija polosti i kamery mogut byt' izucheny tol'ko v netronutoj zalezhi soli na meste. Ispytyvalis' modeli v odnu pjatuju natural'noj velichiny v zalezhah plastovoj soli v Hatchinsone, Kanzas; provodjatsja takzhe polnomasshtabnye polevye ispytanija. (author)}
