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 …

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 …

Irradiation start in WP5
Yesterday (June 1, 2021) we started irradiation of sixty aggregate samples. This is a very important phase in work package 5 Assessing the performance of irradiation of concrete. All samples were inserted into two capsules and put into active zone of light water research reactor LVR-15 being operated by Research centre Rez in Husinec-Rez near …
CoMS_2020/21 international conference
