Costain develops AR system to inspect nuclear pipelines

Project comes in response to a challenge from EDF and Innovate UK

Costain is developing a miniature infrared inspection camera that uses augmented reality to assess potential damage to radioactive pipelines.

The project comes in response to a challenge from EDF and Innovate UK to come up with a solution to detect cracks in pipelines that are more than 40-years-old. Currently, visual inspection is considered to be the most effective technique for material defects but it has limitations.

The deterioration of pipes is assessed subjectively, meaning money is spent on replacing pipes that have a much longer life expectancy. The quality of the footage is also often impacted due to the camera being dazzled by its own illuminator, which can result in areas of the image being hidden.

Costain’s technology – which will be trialled on a pilot basis – will provide an evenly exposed image, while also minimising the radioactive levels. Images of the pipes will be taken every three to six months, and will be overlaid using augmented reality to provide a clear indication of any damage that needs be addressed and any pipes that need to be replaced.

Tony Davies, nuclear business development director at Costain, added: “The technology we will produce will have a positive long-term impact on both EDF and their customers and we hope to see it being utilised over the upcoming year.”
