Advanced Scale Conditioning Agents

The accumulation of deposits in the secondary side of steam generators (SGs) increases the potential for accelerated tube degradation and flow oscillations. As these deposits harden and form crevices, they can cause conditions that lead to tube corrosion. To improve upon traditional mechanical deposit removal techniques and avoid the potential drawbacks of traditional SG chemical cleaning, advanced scale conditioning agent (ASCA) technology was developed in 2000.

Small bore embedded piping internal inspection and corrosion elimination

Solving corrosion-related issues is a major challenge for the worldwide ageing fleet of nuclear power plants, looking for LTO (long-term operation). While utilities can proceed to replacements for many pipes affected by corrosion, a replacement strategy is not always possible. Other maintenance solutions are required for inaccessible or embedded pipes. Moreover, for those pipes which cannot be replaced, internal inspection and corrosion removal become an even greater technical challenge if the pipe’s diameter is small and when the remote access to the zone of interest requires to travel through bended sections and elbows.

Socket Weld Examinations

Socket welds are used in numerous applications throughout the nuclear industry and due to the unique configuration, size and other limitations, ultrasonic inspection can be challenging.
