Radioactive substance leaks from Fukui nuclear power plant in Japan

Jen Mills, Metro 24 Dec 2025

Radioactive water leaked from a disused power plant in Japan today during work to decommission it.

Parts of the Fugen nuclear plant in Fukui Prefecture are being dismantled, and while this took place, around around 20ml of water containing a ‘high’ amount of the radioactive isotope tritium leaked from a pipe.

Japanese broadcaster NHK One reported earlier that detailed investigations were underway to see if any workers were splashed with the water, though internal exposure via inhalation had been ruled out.

Citing the Nuclear Regulation Authority, they said no radioactive material had leaked outside the controlled area of the plant.
