Non-destructive Evaluation of Concrete Damages of Containment Walls in Nuclear Power Plants

Résumé : This paper is focused on the part of the project ANR ENDE that concerns the damage and crack characterization by means of NDT. The tests are done in 3 or 4 points bending in order to study the cracks' generation, their propagation, as well as their opening and closing. The main ultrasonic techniques developed concern linear or non-linear acoustic: acoustic emission [SBA 2015], Locadiff [LAR 2015], energy diffusion, surface wave's velocity and attenuation, DAET [3]. The recorded data contribute to providing the mapping of the investigated parameters, either in volume, in surface or globally. Digital image correlation is an important additional asset to validate the coherence of the NDT results. RÉSUMÉ. Il est nécessaire d'utiliser les méthodes non-destructives pour une bonne évaluation des structures en béton et notamment les ouvrages sensibles comme les centrales nucléaires. Dans le cadre du projet ANR ENDE, plusieurs développements ont été effectués en méthodes non destructives. Cet article présente les résultats d'une large campagne expérimentale qui a pour objectif de qualifier des méthodes END nouvelles pour la détection de l'endommagement diffus et la détection et la caractérisation des fissures (position, longueur, etc.).
