Abstract

The radiant-heat spray calcination process for conversion of liquid wastes to solids is described and the design of a one-gallon-per-hour spray calcination unit coupled with a small melt pot, capable of being run separately as a pot calciner, is discussed. The units were designed to test the feasibility of the calcination process with actual Purex plant waste in terms of the process as a unit operation, off-gas treatment, fission-product behaviour, condensate and calcined waste characteristics. The entire system was made to fit into an available 7-1/2 ft x 15 ft x 15 ft tall, manipulator-equipped, shielded cell which is also described. Included in the design discussion are: the resistance heating of the spray calciner column, thermal insulation of the column, spray nozzle, method of nozzle replacement, induction heating of the melt pot, radioactivity scanner for the pot, off-gas processing system including condenser, scrubber and filters, off-gas sampling device, liquid sampling device, wash-down system, feed system, instrumentation and control methods. The experience gained in operating the calciners and associated equipment is discussed. Experimental results presented show the effectiveness of off-gas decontamination and behaviour of gross chemical constituents and some specific fission products.

(author) [French] Les auteurs etudient le procede de calcination par pulverisation et chauffage radiant utilise pour transformer les dechets liquides en solides; ils decrivent notamment une installation de calcination par pulverisation (d'une capacite de 1 gallon par heure) accouplee a un petit creuset que l'on peut utiliser separement comme creuset de calcination. Cet ensemble- a ete concu pour etudier la possibilite de calciner des dechets reels resultant du traitement Purex, en tenant compte des facteurs suivants: operations dans un seul appareil, traitement des gaz d'echappement, comportement des produits de fission, caracteristiques du condense et des dechets calcines. Tout l'appareillage a ete installe dans une cellule blindee de 2, 50 x 5 x 5 m, pourvue de manipulateurs, qui est aussi decrite dans le memoire. Les auteurs traitent des questions suivantes: chauffage par resistance de la colonne de calcination, isolement thermique de la colonne, ajutage de pulverisation, methode de remplacement de l'ajutage, chauffage par induction du creuset, detecteur de radioactivite du creuset, systeme de traitement des gaz d'echappement (y compris le condensateur, l'epurateur et les filtres), echantillonnage des gaz d'echappement et des liquides, systeme de lavage, instruments et methodes de controle. Les auteurs font part de l'experience acquise dans le fonctionnement des appareils de calcination et du materiel connexe. Les resultats experimentaux presentes montrent l'efficacite de la decontamination des gaz d'echappement et donnent une idee du comportement des principaux elements chimiques constitutifs et de certains produits de fission. (author) [Spanish] En la memoria se describe el proceso de calcinacion poi pulverizacion y calentamiento radiante; asimismo, se describe una instalacion de calcinacion por pulverizacion (de un galon por hora de capacidad) acoplada a un pequeno crisol, que puede utilizarse separadamente como crisol de calcinacion. La finalidad de las instalaciones era permitir el estudio de la posibilidad de aplicar la calcinacion a desechos normales procedentes del proceso Purex, tomando en consideracion los siguientes factores: el proceso como operacion interna, el tratamiento de los gases de escape, el comportamiento de los productos de nssion y las caracteristicas del condensado de los desechos calcinados. El sistema se instalo en una celda blindada - que tambien se describe - de 7, 5 X 15 X 15 pies, equipada con manipuladores. Se hace particular referencia a los siguientes puntos: calentamiento por resistencia de la columna de calcinacion, aislamiento termico de la columna, tobera de pulverizacion, metodo de sustitucion de la tobera, calentamiento por induccion del crisol, detectorde radiactividad de] crisol, sistema de tratamiento de los gases de escape (comprendidos el condensador, el depurador y los filtros) tomamuestras de gases de escape, tomamuestras de liquidos, sistema de lavado, instrumentos de precision y metodos de control. Les autores examinan la experiencia adquirida con el funcionamiento de las instalaciones de calcinacion y el equipo auxiliar. Los resultados experimentales expuestos ponen de manifiesto la eficacia de la descontaminacion de los gases de escape, asi como el comportamiento de los principales constituyentes quimicos y de determinados productos de fision.
