Vessel wall integrity of nuclear power plants
Description
KIVI/NIRIA-NNS symposium:
Vessel Wall Integrity of Nuclear Power Plants
In Doel, four nuclear power plants are located together on a site near the port of Antwerp. In Tihange, three similar nuclear power plants are located along the Meuse River.
During regular maintenance work, abnormalities were found in the material structure of the steel reactor vessels at Doel 3 and Tihange 2 nuclear power plants in the summer of 2012. In the meantime, several investigations have been carried out which show that the vessels have sufficient residual integrity, and discussions are ongoing in Belgium about the start-up of these two plants.
These facts raised questions in the Netherlands about the integrity of the reactor vessel at the Borssele nuclear power plant. It has since been concluded by the regulatory authorities that the situation in Doel 3 and Tihange 2 is so different that there is no safety concern in Borssele. However, as part of continuous improvement, additional measurements were carried out during the most recent fuel swap.
At the symposium, experts will discuss the situations in the Belgian plants and in Borssele and provide an overview of the measurement techniques in use
