Concrete structures can degrade as a result of alkali-silica reactions, and nuclear plants need to develop aging management programs to maintain structural integrity for extended operations. To support that work, this report reviews research on how alkai-silica reactions change the mechanical properties and behaviors of concrete structures.
In nuclear plants, visual inspection techniques—such as viewing directly with the eyes and remote viewing via cameras and fiberscopes—are commonly used to detect cracks in concrete structure and stainless steel surfaces. This report includes a survey of these techniques, an assessment of the effectiveness of algorithms to measure the width of cracks, hardware requirements for […]
