Abstract

In the study of ultimate disposal of high-level radioactive wastes at Brookhaven National Laboratory emphasis is being placed on the formation of phosphate glasses as a means of incorporating the fission products in stable media. Of primary interest here is the development of a process in which the entire conversion from the raw aqueous wastes to the final.glass product would be carried out in an all-liquid system. The phosphate-glass method offers a number of important advantages in this respect and, in particular, lends itself to the development of a continuous process in which the liquid medium would be readily transferable from one process step to another. The paper presents the results of bench-scale studies on the production of phosphate glasses, with the continuous mode of operation, utilizing various types of aqueous wastes. The studies have been in progress for some 20 months and were carried out to determine essential operating parameters with particular attention paid to corrosion resistance and physical integrity of the high-temperature crucible. In addition, the paper discusses flow-sheet development together with the design and results of operation of. an engineering-scale plant having a capacity of 0.5 ft{sup 3} of glass per day with a continuous feed of  More>>

(author) [French] Dans l'etude des methodes d'elimination definitive des dechets de haute activite, le Laboratoire national de Brookhaven attache une grande importance aux verres au phosphate pour la fixation des produits de fission dans un milieu stable. On s'efforce essentiellement de mettre au point un processus dans lequel la transformation, depuis le dechet liquide et l'etat brut jusqu'au produit vitreux final, s'opererait entierement en phase liquide. A cet egard, le verre au phosphate presente un grand nombre d'avantages importants; en particulier, il se prete a la mise au point d'un processus continu dans lequel le milieu liquide pourrait facilement passer d'un stade au stade suivant. Les auteurs exposent les resultats d'etudes en laboratoire sur la production de verres au phosphate, suivant un processus continu, avec differents types de dechets liquides. Ces etudes, qui sont en cours depuis une vingtaine de mois, ont pour objet de determiner les parametres de fonctionnement essentiels, en tenant compte notamment de la resistance a la corrosion et de l'integrite physique du creuset et haute temperature. Les auteurs commentent aussi le diagramme de circulation ainsi que les plans et le fonctionnement d'une installation experimentale pouvant produire 14 dm{sup 3} de verre par jour en etant alimentee de maniere continue avec des dechets simules. (author) [Spanish] En el estudio de los metodos para la evacuacion definitiva de desechos de elevada radiactividad, que se realiza en el Brookhaven National Laboratory, se viene prestando particular atencion a la formacion de vidrios al fosfato como recurso para incorporar los productos de fision a un medio estable. Interesa principalmente encontrar un proceso con arreglo al cual la conversion, desde los desechos acuosos en bruto hasta el producto vitreo final, pueda efectuarse enteramente en fase liquida. En este sentido, el metodo del vidrio al fosfato ofrece una serie de importantes ventajas y, en particular, se presta para el desarrollo de un proceso continuo en cuyo curso el medio liquido puede pasar facilmente de una operacion a otra. El autor expone los resultados de estudios de laboratorio sobre la obtencion de vidrios al fosfato, con arreglo a un procedimiento continuo con distintos tipos de desechos acuosos. Estos estudios se vienen realizando desde unos veinte meses atras y su proposito es determinar los parametros funcionales basicos, prestandose particular atencion a la resistencia a la corrosion y a la integridad fisica del crisol de alta temperatura. Ademas, se examina en la memoria el trazado del diagrama de circulacion, juntamente con el calculo y los resultados obtenidos en la explotacion de una instalacion experimental de una capacidad de elaboracion de 0,5 pies{sup 3} (14 dm{sup 9}) de vidrio por dia, con alimentacion continua de desechos inactivos simulados.

Glavnyj interes predstavljaet razrabotka processa, pri kotorom vodnye othody prevrashhalis' by v okonchatel'nyj steklovidnyj produkt v polnost'ju zhidkoj sisteme. Metod poluchenija fosfatnogo stekla predstavljaet celyj rjad vazhnyh v jetom otnoshenii preimushhestv i, v chastnosti, daet vozmozhnost' razrabotat' nepreryvnyj process* v kotorom zhidkaja sreda mozhet legko napravljat'sja iz odnoj stadii processa v druguju.
