Containment integrity has to be verified and assessed to achieve containment lifetime extension. The aging behavior of a pre-stressed containment is analyzed by long-term evaluation of containment deformation.


The Civil Structure Degradation Assessment uses innovative techniques to evaluate critical structures like containments made of pre-stressed concrete.
The containment deformation under load is evaluated using dedicated measurement techniques. Based on the measurements, long-term containment integrity is assessed under considering bi-axial material behavior. AREVA NP also provides Aging Management for Civil Structures.
