For the lifetime extension of the containment its integrity has to be verified and assessed. In this context, the aging behavior of pre-stressed containments is analyzed by evaluating long-term containment deformation.
AREVA NP's Containment Integrity Assessment uses results from pre-installed sensors or from subsequent installations of sensors at suitable locations on the structure. The containment evaluation is based on the data made available since the start of the monitoring system. Long-term and biaxial material behavior as well as force balance between the section members are factored into the Containment Integrity Assessment.

The pre-stressed containment integrity has been successfully assessed for an European customer.
