Methods for Locating Pool Liner Leakage at Nuclear Power Plants
A state-of-the-art review is complemented by targeted EMAT shear-horizontal guided-wave experiments, which clarify detection mechanisms and practical limitations. Based on the combined findings, Alternating Current Field Measurement (ACFM) is identified as the most promising near-term technique for locating surface-breaking cracks, with Phased Array Ultrasonic Testing (PAUT) as a complementary method for detailed characterization. The results provide an application-oriented basis for prioritizing inspection techniques and guiding future development toward more reliable leakage localization with reduced downtime.

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.

Shear Force Capacity of Existing Concrete Slabs
Shear force capacity in concrete slabs is crucial for structural integrity, especially in nuclear power plants where safety and reliability are paramount. In several cases low or sometimes insufficient shear force capacities have been observed in structural analyses of existing concrete slabs using modern codes. Understanding shear force capacity and how it has been treated in earlier codes helps ensure durability and safety, preventing structural failures.
