Containment Mock-up Tests at Walldof, Germany

摘要

The Walldorf project is to be seen in the framework of the different activities for the containment design of the European Pressurized Water Reactor (EPR). The research centers around pressure tests using a containment mock-up depicting the main features of a steel reinforced concrete containment with a fibreglass reinforced plastic (FRP) liner. Important questions and potential solutions that are of relevance for a real containment, for instance questions relating to reinforcing arrangements, the design of large penetrations, the application of FRP liners as well as the load carrying characteristics and deformation behaviour of the structure, crack development in steel reinforced concrete and, in particular, the effects of a system consisting of steel reinforced concrete and FRP liner on the leak tightness of containment in the case of large concrete deformations had been investigated.
