Abstract

In the Federal Republic of Germany there are nuclear reactors under construction with steam generators inside the reactor pressure-vessel. As a result design repairs of steam- generator tubes are very difficult and cause large shut-down times of the nuclear-power plant. It is known that numerous troubles in operating conventional power plants are results of steam-generator tube damages. Because of the high total costs of these reactors it. is necessary to construct the steam generators especially in such a manner that the load factor of the power plant is as high as possible. The Technischer Ueberwachungs-Verein Rheinland was charged to supervise and to test fabrication and construction of the steam generators to see that this part of the plant was as free of defects as possible. The experience gained during this work is of interest for manufacture and construction of steam generators for nuclear-power plants in general. This paper deals with the efficiency limits of non-destructive testing steam-generator tubes. The following tests performed will be discussed in detail: (a) Automatic ultrasonic testing of the straight tubes in the production facility; (b) Combined ultrasonic and radiographic testing of the bent tubes and tube weldings; (c) Other non-destructive tests.

(author) [French] En Allemagne, on construit actuellement des generatrices nucleaires dans lesquelles les bouilleurs sont installes a l'interieur du caisson etanche du reacteur. Il s'ensuit que les reparations des tubes des bouilleurs sont tres difficiles et provoquent de longs arrets des centrales nucleaires. On sait que de nombreuses perturbations du fonctionnement des centrales classiques sont dues a des dommages dans les tubes des bouilleurs. C'est en grande partie en raison du prix de revient eleve de ces reacteurs qu'il est necessaire de construire les bouilleurs notamment de sorte que le facteur d'utilisation de la centrale soit aussi eleve que possible. C'est le ' Technischer Ueberwachungs-Verein' de Rhenanie qui a ete charge de surveiller et de controler la fabrication et le montage des bouilleurs, pour garantir que cet element de la centrale soit aussi exempt que possible de defauts. L'experience acquise dans l'execution de ces travaux peut etre tres utile pour la fabrication et le montage des bouilleurs de n'importe quel type de centrale nucleaire. Le memoire traite des limitations de l'efficacite des essais non destructifs de tubes de bouilleurs. Les auteurs discutent plus particulierement les essais ci-apres: a) Controle automatique par ultrasons de tubes droits dans l'usine de production; b) Controle combine, par ultrasons et par radiographie, de tubes coudes et de soudures; c) Autres controles non destructifs. (author) [Spanish] En la Republica Federal de Alemania se estan construyendo reactores nucleares con generadores de vapor situados en el interior del tanque de presion. Las caracteristicas de este modelo dificultan considerablemente la reparacion de los tubos del generador que puede llegar a paralizar la central nuclear por largos periodos. Como es bien sabido, muchas de las dificultades para mantener en funcionamiento las centrales nucleares de tipo clasico provienen de averias en los tubos del generador de vapor. Por ello, y teniendo tambien en cuenta como razon no menos importante el elevado costo total de esos reactores, es preciso construir los generadores de vapor de tal manera que el factor carga de la central sea lo mas elevado posible. El Technischer Ueberwachungs-Verein Rheinland se encarga de dirigir e inspeccionar la fabricacion y la construccion de generadores de vapor para que esa parte de las instalaciones carezca en lo posible de defectos. La experiencia adquirida a ese respecto ofrece ademas interes para la fabricacion y construccion de los generadores de vapor que se destinan a las centrales nucleares en general. En la presente memoria se examinan los limites de rendimiento del ensayo no destructivo de los tubos para generadores de vapor. Se describen minuciosamente los siguientes ensayos: a) ensayo ultrasonico automatico de los tubos rectos en la fabrica misma; b) ensayo combinado, ultrasonico y radiografico, de los tubos curvados y de las soldaduras; c) otros ensayos no destructivos.

Pri takoj konstrukcii ochen' trudno remontirovat' truby parogeneratorov, chto vedet k bol'shim prostojam jadernoj jelektro stancii. Izvestno, chto mnogochislennye neispravnosti, vstrechajushhiesja na obychnyh jelektrostancijah, javljajutsja rezul'tatom povrezhdenij trub parogeneratorov. Vvidu vysokih obshhih zatrat neobhodimo stroit' parogeneratory tak, chtooy zagruzka ih po vozmozhnosti byla vysokoj.
