NDE NucCon 2023

Proud of ACES’s organization and participation in the NDE NucCon 2023! The International Conference on Non-destructive Evaluation of Concrete in Nuclear Applications (NDE NucCon) is co-organized by VTT Technical Research Centre of Finland, Aalto University and BAM. While non-destructive evaluation (NDE) of reinforced concrete structures (RCS) in civil engineering applications has a long history, within …

Mid-term Workshop

This week, the Mid-term workshop of our project took place in the Research Centre Řež. The program of the two-day workshop included two blocks of End User Group View presentations and four blocks of ACES working progress. The book of abstracts and presentations can be found in the download section. We thank everyone for their participation …

Students made test samples of concrete

As part of the ACES project, we work with irradiated rock samples, which are further examined in Hot Cells laboratories. The preparation of samples is very time and financially demanding. The cylindrical samples are only about 1 x 1 cm and 1 x 2 cm, and therefore the operator of the Hot Cells needs to …

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 …
