Characterization of neutron and gamma irradiated concrete constituents
These days, the report on characterization of neutron and gamma irradiated concrete constituents is being finalized. This massive experimental work aimed at compiling a database of experimental data which help the nuclear facility operators to assess the residual performance of concrete in highly irradiated environment. Typically, these are the biological shielding structures which are designed …

Completion of Deliverable D4.6 Prediction of creep and shrinkage from mix
In our recent study, we’ve made significant strides in comprehending the complex phenomena of concrete creep and shrinkage. This research significantly enhances our understanding of concrete behavior in crucial applications like nuclear power plants. It has the potential to drive improvements in construction techniques and materials. You can read the entire study now here.
Post-Doctoral Internship: Numerical Study of DEF at the Mesoscale Using a Cohesive-Volumetric Approach
We are pleased to announce the commencement of a post-doctoral internship lasting 18 months, which forms an integral part of the ongoing research efforts at the Institute of Radioprotection and Nuclear Safety (IRSN). This research initiative is focused on understanding the aging process of concrete within the containment buildings of nuclear power plants, with a …

Advancing corrosion safety assessment for concrete structures in NPPs
Through our EU-funded research, ZAG Slovenija and Laborelec identified two effective non-destructive corrosion testing techniques (NDTs) – Pulsed Eddy Current and half-cell Potential Mapping. These portable and cost-effective NDTs enable early detection of steel liner corrosion inside steel cylinder concrete pipes (SCCPs). To automate the inspection process, CEA developed a robotic platform with a manipulator, specifically designed for corrosion NDTs inside …

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 …

The 2nd project meeting
The 2nd project meeting is currently underway at the Finnish VTT in Espoo. The program is very busy. Presentations of individual work packages and meetings of the work groups themselves take place every day. We thank the main coordinator of the project for the organization and hospitality.
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 …
