Abstract

The disposal of radioactive wastes to the ground from the Hanford separations plants is summarized ; volumes of wastes and contained curies discharged to swamps, trenches, and cribs are presented. Significant literature on ion- exchange studies using Hanford soils is reviewed. A field experiment with a model crib is described; preliminary findings indicate that spreading a waste solution below a disposal facility may be of greater benefit in disposal operations than previously assumed. Further studies with the calcite-phosphate reaction are reported; significant variables which affect Sr{sup +2} removal are calcite surface area, pH of the influent, flow rate, temperature and phosphate ion concentration. Bone-seeking radioisotopes are also removed from F- solutions when contact is made with calcite. The zeolite clinoptilolite shows high selectivity for Cs{sup +} even in the presence of increased Na{sup +} concentration. The effect of the large-scale ground disposal operation at Hanford is described by means of a map and geological cross-sections showing areas and volumes of ground and ground water contamination.

(author) [French] Les auteurs donnent un apercu de l'elimination dans le sol des dechets radioactifs des usines de separation des isotopes de Hanford ; ils indiquent les quantites de dechets - et de curies - qui sont evacuees dans des marecages, des tranchees et des coffres. Ils passent en revue des etudes importantes qui ont ete publiees sur les proprietes d'echangeurs d'ions des sols de Hanford. Ils decrivent une experience pratique faite avec un coffre modele; il ressort des resultats preliminaires que le fait de repandre une solution de dechets au-dessous d'une installation d'evacuation pourrait etre beaucoup plus avantageux pour les operations d'evacuation que l'on n'avait cru precedemment. Les auteurs signalent d'autres etudes fondees sur la reaction calcite-phosphate ; parmi les variables importantes qui influent sur l'elimination du Sr{sup ++}, il faut citer: la zone de surface de la calcite, le pH du liquide de dilution, la vitesse de circulation, la temperature et la concentration des ions de phosphate. Au contact de la calcite, les radioisotopes osteophiles sont egalement retires des solutions de F-. La clinoptilolite zeolitique manifeste une selectivite elevee pour le Cs{sup +}, meme en presence d'une concentration accrue de Na{sup +}. Les effets d'une vaste operation d'elimination dans le sol a Hanford sont exposes a l'aide d'une carte et de coupes transversales des couches geologiques indiquant les zones d'evacuation et les degres de contamination des terrains et des nappes d'eau souterraines. (author) [Spanish] Los autores describen brevemente los metodos utilizados para la evacuacion en el subsuelo de los desechos radiactivos de las instalaciones de separacion de Hanford; indican tambien las cantidades de desechos evacuados en estanques, zanjas y cajas, y su actividad en curies. Dan cuenta, ademas, de las publicaciones mas importantes sobre los estudios de intercambio ionico realizados utilizando tierras de Hanford. En la memoria se describe una investigacion sobre el terreno efectuada con una caja experimental; los resultados preliminares indican que la dispersion de una solucion de desechos debajo de una instalacion de evacuacion puede tener un efecto mas beneficioso de lo que se suponia. Se describen nuevos estudios sobre la reaccion calcitafosfato ; los factores que afectan la separacion del Sr{sup +2} son la extension superficial de la calcita, el pH del afluente, el caudal, la temperatura y la concentracion del ion fosfato. Los radioisotopos osteofilos pueden separarse de las soluciones de F- poniendolas en contacto con calcita. La clinoptilolita de ceolita presenta una elevada selectividad para el Cs{sup +}, incluso en presencia de una concentracion mas elevada de Na{sup +}. Los efectos de la evacuacion en gran escala de desechos radiactivos en el subsuelo de Hanford se indican mediante un mapa y secciones transversales geologicas, que muestran el volumen de las aguas freaticas y la superficie del terreno contaminados. (author) [Russian] Dajutsja vyvody po udaleniju radioaktivnyh othodov v zemlju s hjenfordskih zavodov po razdeleniju izotopov. Opisyvaetsja udalenie vysokoaktivnyh othodov v bolota, rvy i vyrabotki. Daetsja obzor literatury po izucheniju ionnogo obmena pochvy v rajone Hjenforda. Daetsja opisanie jeksperimenta v polevyh uslovijah s model'ju vyrabotki; predvaritel'nye rezul'taty pokazyvajut, chto rassredotochenie othodov pod ustanovkoj dlja ih udalenija mozhet predstavljat' bol'shuju vygodu, chem ranee predpolagalos'. Takzhe soobshhaetsja o reakcii kal'cit-fosfata. Vazhnymi peremennymi velichinami, vlijajushhimi na udalenie Sr{sup +2} javljajutsja vneshnjaja poverhnost' kal'cita, pH slivaemyh othodov, skorost' potoka, temperatura i soderzhanie ionov v fosfate. Radioizotopy, kotorye mogut nakaplivat'sja v kostjah, takzhe udaljajutsja iz F- rastvorov, kogda imeetsja kontakt s kal'citom. Ceolit klinoptilolit pokazyvaet vysokuju izbiratel'nost' dlja Cs{sup +} dazhe v prisutstvii povyshennoj koncentracii Na{sup +}. Vlijanie udalenija othodov v zemlju v krupnyh masshtabah v Hjenforde pojasnjaetsja s pomoshh'ju karty i teologicheskih razrezov, pokazyvajushhih razmery zagrjaznenija zemli i gruntovyh vod. (author)}
