Corrosion of steel liners

Corrosion of steel liners inside concrete structures is one of the concerns in the aging management of Nuclear Power Plants (NPP). WP2 of the ACES project is addressing two cases where safety is the major challenge: chloride-induced corrosion of Steel Cylinder Concrete Pipes (SCCP) and crevice corrosion of steel liner embedded in the concrete of …

Experimental study and modeling of the effect of prestressing on the internal swelling reactions of concrete

Internal swelling reactions (ISR) can lead to the degradation of concrete due to expansion induced by such chemical reactions. ISR are common in massive concrete structures such as nuclear power plants that contain prestress reinforcement and are thus submitted to creep. Recent research shows the importance of the effect of prestressing on the reduction of …

Deliverable 1.1 done

ACES finished the state of the art report on the knowledge of the quantitative assessment of ageing of concrete in nuclear power plants. The report provides general guidance on ageing management of concrete structures in nuclear power plants based on international recommendations and a concise description of different concrete degradation and ageing processes. The report …
