Long term stability of tendons and post tensioning wires
Material properties and structure of the wires and tendons change over time in a post tensioned design, and it is important to investigate the long term performance.
This project is based on a literature study and data from long term measurements from surveillance data from reactor containments in the nuclear power plants Ringhals and Forsmark.

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.

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.
