Periodic in-service inspection is carried out during maintenance outages to deliver essential input for assessing the structural integrity of primary circuit components.
NDT can assess the current condition of a component or system and allow personnel to evaluate whether it is fit for service and the remaining service life. Such evaluation, which can be done with minimal downtime, can help plant personnel develop strategic plans for system maintenance that extend the life cycle.

Boilers, Headers, Steam lines, Turbines, Feed water Heaters, Condensers are some of the main components associated with power generation.

The reason for the inspection depends on the component and its role in the plant operation.
