Abstract

Studies of various reactor types undertaken by the Commissariat a l'energie atomique have led to the use and-development of many non-destructive methods of testing the various materials employed in their construction, and especially methods involving the use of X- and {gamma}-rays, ultrasonic waves and eddy currents. A summary is given below of the tests carried out during the construction of EDF (graphite gas) and EL 4 (heavy water) reactor types and of co-laminated elements. Emphasis is laid on certain typical aspects of these various methods, some of which are well known. EDF type: ultrasonic measurement of the wall thicknesses of uranium or uranium alloy tubes; gamma- radiographic detection of voids in the tubes; ultrasonic inspection following heat treatment of the tubes ultrasonic flaw detection (inclusions, pipes) in billets and rough casts for MgZr cladding; leak-tightness testing of slugs by helium eliquation. EL4 type: ultrasonic and eddy-current measurements of the wall thicknesses of Zircaloy pressure and guide tubes; ultrasonic inspection of Zircaloy pressure tubes and stainless-steel cladding tubes; in vacuo radiography of Be claddings; leak-tightness testing of pencils by helium eliquation. Co-laminated elements; cladding thickness measurements by pulsed eddy currents; determination of core position in tubes and plates, using X-rays, gamma  More>>

The methods have been developed for industrial use. Several of the inspections already constitute routine manufacturing procedures, others will be introduced shortly and a further number are likely to come into use at a later date. (author) [French] Les etudes de divers types de reacteurs entreprises par le CEA ont conduit a utiliser et a mettre au point de nombreuses methodes de controle non destructif pour les differents materiaux entrant dans leur realisation, en particulier: radiographie et gammagraphie, methodes ultrasonores et courants de Foucault. Le memoire decrit les controles effectues au cours de la fabrication des reacteurs des filieres EDF (graphite- gaz) et EL4 (eau lourde) et des elements colamines. Les auteurs insistent sur quelques points caracteristiques de ces diverses methodes, dont certaines sont bien connues. Filiere EDF: mesure des epaisseurs des parois des tubes en uranium ou uranium allie, par ultrasons; recherche des cavites de ces tubes, par gammagraphie; controle des traitements thermiques de ces tubes, par ultrasons; recherche des defauts (inclusions, criques), par ultrasons dans les billettes et ebauches des gaines en MgZr; controle de l'etancheite des cartouches, par ressuage d'helium. Filiere EL 4: mesure des epaisseurs des parois des tubes de force, et de guidage en Zircaloy, par ultrasons et courants de Foucault; examen des tubes de force en Zircaloy et tube de gaine en acier inoxydable par ultrasons; radiographie sous vide des gaines en Be; controle d'etancheite des crayons, par ressuage d'helium. Elements colamines : mesure de l'epaisseur des gaines, par courants de Foucault puises; recherche de la position de l'ame sur tubes et plaques, par radiographie, comptage gamma et courants de Foucault puises; controle de l'homogeneite.du combustible, par comptage gamma; detection des defauts dans les billettes en ZrU, par ultrasons et gammagraphie; recherche des zones decollees des plaques, par ultrasons, courants de Foucault puises et mesure de resistivite. Ces mises au point ont ete faites en vue de leur utilisation industrielle. Plusieurs de ces controles sont effectues couramment en cours de fabrication, d'autres le seront prochainement et certains sont susceptibles de l'etre a plus longue echeance. (author) [Spanish] Los estudios del Commissariat a l'Energie Atomique sobre diversos tipos de reactores indujeron a utilizar y a perfeccionar numersos metodos no destructivos destinados a inspeccionar los distintos materiales que intervienen en la construccion de esos reactores; en particular radiografia y gamma- grafia, metodos ultrasonicos y empleo de corrientes de Foucault.. A continuacion se enumeran las operaciones de control llevadas a cabo durante la construccion de reactores pertenecientes a las familias EdF (grafito-gas) y EL 4 (agua pesada), y de elementos colaminados; se hace hincapie en ciertos aspectos caracteristicos de estos metodos, algunos de los cuales son ya bien conocidos. Familia EdF: metodos ultrasonicos para medir el espesor de las paredes de tubos de uranio o aleacion de uranio ; localizacion de las cavidades en esos tubos por gammagraffa; empleo de medios ultrasonicos para control de los tratamientos termicos a que se someten los tubos; empleo de procedimientos ultrasonicos para buscar fallas (inclusiones, grietas) en las palanquillas y barras con que se elaboran las vainas de Mg-Zr; control de la estanqueidad de los elementos mediante exudacion de helio. EL4: uso de metodos ultrasonicos y corrientes de Foucault para medir espesores de pared en tubos de Zircaloy, sean de fuerza o de guia; empleo de metodos ultrasonicos para inspeccionar tubos de fuerza de Zircaloy y vainas de acero inoxidable; radiografia al vacio de vainas de Be; control de la estanqueidad de barras huecas mediante exudacion de helio. Elementos colimados: medida del espesor de vainas mediante el empleo de corrientes de Foucault pulsadas; verificacion de la posicion del alma en tubos y placas mediante radiografia, recuento gamma y aplicacion de corrientes de Foucault pulsadas; control de la homogeneidad del combustible por recuento gamma; deteccion de defectos en barras de Zr-U mediante procedimientos ultrasonicos y gammagraficos; determinacion de las zonas despegadas en placas, empleando metodos ultrasonicos, corrientes de Foucault pulsadas y medicion de resistividad. Estos metodos se han desarrollado con miras a su utilizacion industrial. Algunos de ellos se aplican ya corrientemente durante la fabricacion; otros se utilizaran proximamente y el resto es susceptible de aplicacion a mas largo plazo.
