Testing of acoustic cameras to detect leakage through a concrete structure
The acoustic cameras were tested by personnel from Ringhals NPP with earlier experience from using acoustic camera during containment leak rate test. The main result is that you should not relay entirely on the camera. A combination of camera and leak spray is recommended.

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.
