Abstract

Full text: The measurement of wall thickness of austenitic and non-ferrous sheets, tubes and containers is presented. Two methods for contactless measurement are discussed: eddy- current method for measuring the thickness of non-ferrous and austenitic sheets and containers by means of transition coils; eddy-current measurement of the wall thickness of tubes by means of feed-through coils. Suitable instruments and their application are shown. Wall-thickness measurement on non-ferrous reactor assemblies by the ''magnetic ball method'' is also discussed. The principle of this new type of measurement is explained, its range of use - especially for spot- measurements - is discussed, and a practical instrument is described. Measurement of non-magnetic coatings on magnetic base materials is discussed. The measurement principles (magnetic DC and AC field methods) are explained and instruments for measurement of nonmagnetic coatings between 3-{mu}m and 20-mm thickness are shown. The special problem of measurement of stellite deposits on ferritic walls of reactor vessels is discussed. The measurement of electrically non-conductive coatings on base materials consisting of non-ferrous metals; and the principle of measurement (eddy currents) are explained. An instrument for this purpose is shown and typical examples of measurements are given. Contactless in-line measurements of physical dimensions of metallic  More>>

An instrument for this purpose is shown and typical examples of measurements are given. Contactless in-line measurements of physical dimensions of metallic reactor components are given. Various methods for ferrous and non-ferrous metals are explained (magnetic DC and AC field method, eddy-current methods). Instruments and examples for remote measurements of diameter, ovality, distortion etc., of reactor components are described, and methods of measuring the spacing of such components in the ''hot'' zone of the reactor are shown. An instrument for recording the surface profile and for direct reading the roughness values (''Rauhtiefe'', ''Glaettungstiefe'', CLA value and RMS value) is shown. Typical examples of the use of the instrument for reactor components are discussed. Special attention is given to the possibility of using a small and versatile pick-up by means of manipulators in the ''hot'' zones and on ''hot'' materials. The increase of surface roughness with increasing irradiation dose is discussed.

Deux methodes de mesure des epaisseurs sans contact sont discutees: la mesure, par courants de Foucault, de l'epaisseur de feuilles et des parois de recipients en metaux non ferreux ou en aciers austenitiques, au moyen de bobines se deplacant le long des pieces a examiner: la mesure, par courants de Foucault, de l'epaisseur des parois de tubes, au moyen de bobines dans lesquelles se deplacent les pieces a examiner. L'auteur decrit des instruments appropries et le mode d'utilisation. Il discute egalement la mesure de l'epaisseur des parois de parties constitutives de reacteurs, en metaux non ferreux, par la 'methode de la bille magnetique' et explique le principe de ce nouveau type de mesure et son domaine d'utilisation - notamment pour les mesures par points; il decrit un instrument approprie. L'auteur examine la mesure des revetements non magnetiques de materiaux magnetiques; il explique les principes de mesure (methodes fondees sur les champs magnetiques des courants continus et des courants alternatifs) et decrit des instruments de mesure de revetements non magnetiques dont l'epaisseur varie entre 3 {mu}m et 20 mm. Il expose le probleme special de la mesure des depots de stellite sur les parois en aciers ferritiques des cuves de reacteurs. La mesure des revetements non conducteurs de metaux non ferreux est etudiee. Le memoire explique le principe de mesure (courants de Foucault). Il decrit un instrument approprie et donne des exemples de mesures typiques. L'auteur examine egalement la mesure sans contact, en continu, des dimensions de parties constitutives metalliques de reacteurs et explique diverses methodes de mesure pour les metaux terreux et non terreux (champs magnetiques des courants continus et des courants alternatifs, courants de Foucault). Il decrit des instruments et donne des exemples de mesure telecommandee du diametre, de l'ovalisation, de la distorsion, etc., de diverses pieces; il expose des methodes de mesure de l'espacement des elements de la zone active du reacteur. Le memoire decrit un instrument permettant d'enregistrer le profil de surface et de faire la lecture directe des valeurs de la rugosite (profondeur de rugosite, degre de polissage, direction des irregularites et valeur quadratique moyenne). Il donne des exemples typiques d'emploi de cet instrument pour les pieces d'un reacteur. L'auteur traite en particulier de la possibilite d'utiliser un petit lecteur polyvalent, a l'aide de manipulateurs, dans les zones actives et pour les matieres 'chaudes'. Il discute l'augmentation de la rugosite de surface en fonction de l'accroissement de l'irradiation.
