Nuclear Power Concrete Technology

This research program provides new knowledge for managing concrete structures at both Swedish and Finnish nuclear power plants. The purpose is to safeguard the entire life of the structures whilst ensuring safe, reliable and cost-effective operations. In order to do that, we need to build new expertise in concrete technology.

Betongteknik kärnkraft

We also contribute to building expertise in the nuclear industry, the government, universities and high schools. Our program includes both doctoral projects and contract research. The focus of the research is to:

• investigate local climates in the reactor inclusion to identify environments that cause degradation and affect the density of the enclosure
• develop tools for studying clamping cables and sealing plates
• verify calculation tools used in the reactor inclusion
• investigate safety-related issues in the waterways

    Inspection of Pipes in Leak Indication Systems

    Leak indication systems can detect leakage from fuel pools early. These systems consist of long systems of pipes with very small diameters, which can lead to blockages which is very important to prevent. but finding methods for this is difficult due to the geometrical complexity. Therefore, this study examined possible methods for detecting and removing mineral blockages in narrow, embedded leak indication pipes with sharp bends.

    Syntesrapport 2007-2024: Betongtekniskt program kärnkraft

    Energiforsk driver sedan 2007 ett forskningsprogram kring betongkonstruktioner inom kärnkraftverken. Det finns ett behov av att bygga både kompetens och att utveckla teknikbasen för teknisk förvaltning av byggnader och konstruktioner inom kärnkraftindustrin.

    Testing of acoustic cameras to detect leakage through a concrete structure

    The purpose of the project was to see how well the acoustic cameras worked on a concrete containment with known leakage through the structure.
