MAEVA, a mock-up near Civaux nuclear power plant for containment evaluation in accident conditions

摘要

In 1996, EDF has decided to construct a containment model at the scale 1:3, the MAEVA mock-up, in order to study the integrity of a prestressed concrete containment without liner in terms of mechanical strength and leaktightness, for loadings corresponding to its design and beyond design conditions. In parallel to the construction and testing of the mock-up, a R&D programme, the CESA project will permit to compare predictive calculations of the behaviour of the mock-up to the experimental results.
