Japan suspends Fukushima water release after quake as precaution

Fukushima nuclear plant suspends wastewater release after earthquake, no radiation leak detected, operations to resume.

The release of wastewater from Japan's stricken Fukushima nuclear plant was temporarily suspended on Friday following an earthquake, its operator said.

A 5.8-magnitude jolt struck off the coast of the northeastern Fukushima region, home to the plant wrecked by a tsunami in 2011, at 00:14 a.m. Friday (1514 GMT Thursday), the Japan Meteorological Agency said.

"We have confirmed remotely that there were no abnormalities on ALPS treated water dilution/discharge facility, etc.," Tokyo Electric Power Company (TEPCO) said on X, formerly Twitter, referring to the water release process.

But "to be on the safe side, we have suspended the operations of the facilities in accordance with the pre-defined operational procedures", it said in the early hours of Friday.

Several hours later TEPCO said in a statement that "no abnormalities were detected" and a spokesman told AFP that the water release would resume later on Friday.

No leak of radiation was detected after TEPCO finished necessary checks while "readings from monitoring posts remain normal", he added.

Japan's nuclear regulatory authority also said shortly after the quake that no abnormalities were detected at either the wrecked Fukushima Daiichi plant, or its sister plant Fukushima Daini.
