Modelling of ageing in concrete nuclear power plant structures

Objective

MAECENAS will develop a comprehensive reliability-based analysis assessment tool to determine the risk of an unacceptable reduction in the structural safety of reinforced PCCV and PCPVs as a result of operational and environmental ageing effects.
For the first time a complete analysis capability will exist that considers the complex moisture transport, creep, shrinkage and fracturing processes under elevated temperature for concrete suffering multi-axial stress states. This can lead to a step-change in the interpretation of condition and assessment of appropriate repair strategies.
Test data on the behaviour of aged concrete will be gathered to create a thermodynamically consistent constitutive theory. The project will involve close collaboration between leading academic institutions and senior engineers from within the nuclear industry.
