Abstract

Acidic wastes from the recovery of enriched uranium from aluminium, zirconium, and stainless-steel fuels at the Idaho Chemical Processing Plant are stored in underground tanks of two configurations and nominal sizes of 30,000 and 300,000 gallons. The design and operation of the waste-tank farm as well as the methods of environmental disposal of low-level wastes is described. The ''concentrate and contain'' philosophy of waste disposal has as its ultimate aim the production of a solid mass containing the fission products. The disadvantage of increased treatment costs may or may not be offset by reduction in storage costs. The low thermal conductivity of solids makes storage temperature considerations more important than for liquids. The acid aluminium nitrate wastes from the processing of fuels of the Material Testing Reactor type may be converted to granular alumina by calcining in a fluidized bed from 350 Degree-Sign to 550 Degree-Sign C. The major process components are the NaK heated calciner, an off-gas cleaning system and the solids storage vessels. The process design and the research and development programme are reviewed. On the basis of the successful demonstration of fluidized-bed calcining and high-temperature solids storage in conjunction with other considerations, a number of future storage  More>>

(author) [French] A l'usine de traitement chimique de l'Idaho, les dechets acides provenant de la recuperation de l'uranium enrichi contenu dans les cartouches de combustible en aluminium, zirconium, et acier inoxydable sont stockes dans des reservoirs souterrains de deux formes differentes et d'une capacite theorique de 30,000 et de 300,000 gallons. L'auteur donne une description du plan et du fonctionnement de l'annexe ou se trouvent les reservoirs a dechets, ainsi que des methodes d'elimination des dechets de faible activite dans le milieu ambiant. Le but meme du systeme qui consiste a concentrer et a incorporer dans d'autres substances les dechets a eliminer est la production d'une masse solide contenant les produits de fission. L'inconvenient que constituent les frais de traitement plus eleves peut etre parfois compense par une reduction des frais de stockage. La faible conductivite thermique des corps solides donne plus d'importance a la temperature de stockage que dans le cas de liquides. Les dechets acides de nitrate d'aluminium provenant du traitement des combustibles du type de ceux que l'on utilise dans les reacteurs d'essai des materiaux peuvent etre transformes en aluminium granule par voie de calcination dans un lit fluidifie a une temperature allant de 350 Degree-Sign a 550 Degree-Sign C. Les principaux elements de l'installation sont: un calculateur chauffe au NaK, un systeme d'epuration des gaz d'echappement et un ensemble de recipients pour le stockage des matieres solides obtenues. L'auteur donne un apercu du processus de traitement et du programme de recherche et de mise au point. L'auteur examine un certain nombre de systemes futurs de stockage et leurs incidences sur le milieu ambiant en prenant pour base les resultats positifs de la demonstration du systeme de calcination a ht fluidifie et d'emmagasinage a haute temperature ainsi que d'autres considerations. (author) [Spanish] En la planta de tratamiento quimico de Idaho, los desechos acidos procedentes de la recuperacion del uranio enriquecido de los combustibles nucleares que contienen aluminio, zirconio y acero inoxidable se almacenan en tanques subterraneos de dos formas, con capacidades nominales de 30,000 y 300,000 galones. El autor describe la organizacion y funcionamiento de la seccion de tanques, asi como los metodos utilizados para la evacuacion de desechos de baja actividad. La evacuacion de desechos con arreglo al, principio de la 'concentracion y confinamiento' tiene por finalidad la obtencion de una masa solida que retenga los productos de fision. Los gastos mas elevados que este tratamiento supone pueden a veces quedar compensados por la reduccion de los gastos por concepto de almacenamiento. La baja conductividad termica de los solidos obliga a conceder mayor importancia a la temperatura de almacenamiento que en el caso de los liquidos. Los desechos acidos de nitrato aluminico que se forman al tratar los combustibles del tipo utilizado en los reactores de ensayo de materiales (MTR), pueden transformarse en alumina granular por calcinacion en un lecho fluidificado, a una temperatura comprendida entre 350 Degree-Sign y 550 Degree-Sign C. Los principales componentes de tal instalacion son: el calcinador alentado por una aleacion de NaK, un sistema.de depuracion de los gases desprendidos y los tanques para el almacenamiento de solidos. El autor describe el diseno de la instalacion, asi como el programa de investigaciones y desarrollo. Basandose en los resultados favorables obtenidos con este sistema de calcinacion en lecho fluidificado y almacenamiento de solidos a elevada temperatura, y en otras consideraciones, el autor examina diversos sistemas de almacenamiento y sus relaciones con el medio ambiente.

V dokumente opisyvajutsja konstrukcii i rabo ta ustanovki dlja hranenija othodov v bakah, a takzhe metody udalenija v okruzhajushhuju sredu othodov s nizkim urovnem aktivnosti. Princip ''koncentracii i uderzhanija'' pri udalenii othodov vylilsja v konechnuju formu proizvodstva tverdoj massy, soderzhashhej produkty delenija. Nevygoda ot uvelichenija stoimosti obrabotki mozhet byt' pokryta sokrashheniem stoimosti hranenija, no ne vo vseh sluchajah. Vvidu nizkoj teploprovodnosti tverdyh tel soobrazhenija o temperature hranenija igrajut bolee znachitel'nuju rol', chem dlja zhidkih tel.
