The technology, developed by US-based Nuccorp, eliminates the need for periodic venting and ultrasonic testing inspections.

If allowed to accumulate, air and gas can compromise the proper operation of the emergency core cooling system, Areva said.

The NGAT continuously monitors the accumulation of of air and gas, while it allows for quick ventilation of the affected system to ensure the plant’s continued safe operation.

According to Areva, the device can be easily established at existing plants and has already been successfully demonstrated in operation.

Areva installed base business unit senior vice president George Beam said, "This agreement is yet another example of AREVA’s support of the U.S. nuclear fleet’s mission to generate safe and reliable electricity.

"We are pleased to be the exclusive channel for this innovative technology, as it is the only solution that allows customers to completely verify, measure and eliminate gas in station systems."
