In the Nordic countries, the reactor containment is designed as a cylindrical concrete structure prestressed by horizontal and vertical tendons that can be bonded or unbonded. The stress of the tendons is an important security function for the containment in case of accident.

The aim of this study is to analyze prestressed bonded tendons obtained through the decommissioning of Barsebäck nuclear power plant, to better understand the factors that influence their performance. The results show that it is possible to estimate the stress in bonded tendons through instrumentation and cutting of cables. Furthermore, the article shows that Barsebäck's tendons have lost remarkably little of their stress.

    Deformationer och töjningar resulterande av håltagning i reaktorinneslutning på Ringhals 2

    Structural modifications to nuclear power plant containments require careful assessment to maintain safety margins. Changes can influence stresses and deformations, making reliable measurement and interpretation essential for safe operation and long-term integrity.

    Wood-induced corrosion on steel plates embedded in concrete

    The issue of wood-induced corrosion on concrete embedded steel plates is important for nuclear power plants, as it can potentially lead to structural integrity problems. This laboratory study aimed to investigate initiation and short-term development of this specific type of corrosion. The report is only available in Swedish with an English summary.
