| Popis: | International audience; French Projects of Investment for the Future, called “Research for Nuclear Safety and RadiationProtection” have been initiated to further research on the causes, the management, the impact of theobserved nuclear accidents and to propose and validate solutions to limit the risk and the consequences.In this context the "Non Destructive Evaluation of nuclear plants containment” project” (ENDE) witheight partners (six research institutes and two industrials) supported by the “National Agency of Research”,proposes a methodology for the Non Destructive Evaluation of the containment capacity to fulfil its twomajor functions: strength and leak tightness. The NDE measurements will be performed underconditions representing the specific solicitations of a decennial inspection, and after or during areference accident.The project aims to develop NDEs, to combine them by data fusion and to select the most efficientcombinations with quantitative criteria.The work is based on:• Structuring the knowledge and developing an experimental plan.• Evaluating the material in representative conditions of accidental solicitations (water saturation,porosity, strength, elastic modulus, stress) and the diffuse thermal damage (micro cracks)• Monitoring the transition from diffuse to continuous damage (cracks) and monitoring a crack understress (opening and width).• Implementing ND Techniques on-site.The ND techniques retained after selection will be implemented on a containment mock-up on the 1/3scale. This mock-up developed by EDF (Electricité de France) will be available in 2016. It will becomparable to those of real size containment regarding pressure and temperature conditions. Themeasures deduced from the NDEs will be introduced in another project (Macena) that aims to simulatethe water and heat transfers as well as creep occurring in a reference accident. We will present themethodology and the results obtained during the first year and a half. |
