According to media reports, the US government performed the act after a French company that part owns and helps operate it warned of an "imminent radiological threat.

The warning included an accusation that the Chinese safety authority was raising the acceptable limits for radiation detection outside the Taishan Nuclear Power Plant in Guangdong province in order to avoid having to shut it down, according to a letter from the French company to the US Department of Energy obtained by CNN.

Despite the alarming notification from Framatome, the French company, the Biden administration believes the facility is not yet at a "crisis level," one of the sources told the American news channel.

While US officials have deemed the situation does not currently pose a severe safety threat to workers at the plant or Chinese public, it is unusual that a foreign company would unilaterally reach out to the American government for help when its Chinese state-owned partner is yet to acknowledge a problem exists.

The scenario could put the US in a complicated situation should the leak continue or become more severe without being fixed, the news channel reported.
