In an update to the story we began covering yesterday, China says that there was no radiation leak at the Taishan Nuclear Power Plant and radiation levels around the plant did not rise beyond acceptable limits. A media report on Monday said the US government was assessing a report of a leak at the Taishan plant in China’s southern Guangdong province, and that the station’s French operator Framatome had reported a “performance issue”. China’s Ministry of Ecology and Environment has subsequently said that an increase in radiation levels had been detected in the primary circuit at Taishan’s Unit 1 reactor, but they were within the parameters for safe operations.
