Inspection Services

Highly radioactive and contaminated components are hard to access for human personnel. Therefore we develope special tooling, combining inspection equipment and robotics. The resulting remotely controlled inspection is performed on site, in a quick, efficient and responsible manner. The types of inspections we perform are:

NRG is your partner for Non-Destructive Testing. We are especially proficient in performing regular inspections, or inspecting difficult to reach components in your facility. Contact us for the possibilities!

To inspect a difficult to reach weld in a reactor vessel, the Inspection & Services team from NRG developed a remotely operated vehicle (ROV). By combining our ROV with an ultrasonic scanner and Eddy Current sensors, we were able to inspect the weld at 20 meters of depth within two hours.

Under supervision of a nuclear regulator, this technique and our Inspection Team personnel has been successfully ENIQ-qualified on open and blind test subjects.

How do you assess the condition of tap ends without disassembling components? We developed a robot able to guide a phased array sensor over the tap end. Software sends the ultrasonic sounds along the threads in the tap end. In one rotation, the whole tap end is assessed!

Our technique is tested on tap ends with small, deliberately applied tears to ensure quality and provide technical substantiation.

Combining an Eddy Current probe with ultrasonic sensors, we are able to surface inspection of welds on a pump. Our Ectane device enables us to make very efficient use of the available inspection time.

Our technique was qualified on a 1:1 reference piece of the weld, available in our test facility in Arnhem. All personnel is trained on using the devices in the same facility.
