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.

Gap formation between steel liner and cylinder wall in reactor containment buildings
The reactor containment building is the most important safety barrier in a nuclear power plant. It is a cylindrical, prestressed concrete structure with an embedded steel liner on the inner face of the containment wall, designed to maintain integrity in the event of an internal accident.
