A French energy company says it is working to resolve a "performance issue" at a nuclear plant in China following claims of a potential leak.EDF Energy confirmed that gases that had built up in a component of the plant were deliberately released.
It comes after CNN reported that the US government had been assessing reports of a leak at the Taishan plant.
The facility's Chinese part-owner, China Guangdong Nuclear Power Group, refuted claims of a leak on Monday.
AFP news agency reports the gases released were xenon and krypton.
The International Atomic Energy Agency (IAEA) announced it has "no indication that a radiological incident occurred".
