CHIM
The CHIM scanner was designed for inspection of the steam generator channel head to tube sheet weld. The scanner allows probe changes by the support of the vessel leg, without loss of the scanning datum.
Inspection of the steam generator channel head to tube sheet weld is particularly difficult behind each of the vessel’s support legs. The CHIM scanner allows scanning of this section using a low profile modular scanner which is supported off the vessel leg. Holding a single probe, the scanner is designed to allow probe changes without its complete removal and therefore loss of the scanning datum.
