A tower at a nuclear research institute northeast of Tokyo has collapsed due to strong winds generated by Typhoon Faxai. Officials say no one has been injured and no radioactive substances have been released into the environment.
Representatives from the Japan Atomic Energy Agency said workers at the agency's institute in Oarai Town, Ibaraki Prefecture, discovered on Monday that a cooling tower had collapsed.
The wooden tower was 16.5 meters high and 30 meters wide. It was built in 1968.
Officials said that a testing reactor near the tower has been offline since 2006 and that the tower itself does not contain radioactive substances.
They said there have been no changes in the measurements at radioactivity monitoring posts in and around the institute.
A senior official at the agency apologized for the trouble that has been caused.
