Concrete containment management using the Finite Element technique combined with in-situ Non-Destructive Testing of conformity with respect to design and construction quality, CONMOD

Funded under: FP5-EAECTP C

Abstract

CONMOD is an exercise project that involves combining advanced finite element analysis and the latest non-destructive examination techniques with the aim of establishing the condition of reinforced concrete structures, as well as their present and future behaviour under various loading conditions including the effects of ageing. The subject of this work has been the nuclear power containment of Barsebäck 1 and the MAEVA mock-up.
It can be said that CONMOD is a response to recognition of the fact that there is a real need for a new approach to what is commonly termed ageing management of concrete structures. It is also an attempt to demonstrate the need to combine new technologies harmoniously and to explore their mutual benefits effectively.
CONMOD is unique in the sense that the investigative techniques have been applied to an actual containment structure. In this sense the work is highly qualified to respond to the question as to whether this kind of investigative process is really necessary and possible, i.e. for this type of structure and using these techniques. This doubt stems partly from a lack of understanding of the issues that are relevant, as well as a scepticism towards the reliability of NDE techniques. These are dealt with in CONMOD.
