IHI Southwest Technologies. and Newton Labs completed a robotic examination of an in-service condensate storage tank (CST) at a United States nuclear reactor during the plant’s 2014 autumn outage. IHI engineers conducted the inspection of the tank floor by utilising a combination of phased array ultra-sound, eddy current, laser scanning, and high resolution cameras, all mounted on an Inspector-series underwater robot designed, manufactured and operated by engineers from Newton Labs.
