OMS helps clients to replace aging pipework

A client in the nuclear industry approached OMS to ask us to assist with one of the steps associated with removing and replacing some aging pipework in the primary circuit of a nuclear power plant.

Due to the radiation levels, each process needed to operate as quickly and efficiently as possible. Adding to the challenge, the internal diameter of the pipework varied from approximately 700 mm to 800 mm and the only access was via a small entry hole, measuring approximately 400mm.

OMS were chosen because of our track record of providing industry-leading metrology and visual testing equipment. Due to the specific project requirements, we developed a new system equipped with multiple high-definition cameras to see the areas of interest with varying levels of magnification. The unit was also equipped with laser profilometry to accurately measure the region of interest before and after various steps were carried out. OMS’s proprietary software enables easy overlaying of scans to detect and measure small differences (such as material removal) between scans – even if the tilt of the robot varies between scans.

If you have a challenging nuclear project, we may be able to help. Contact us.
