Osaka Court Set To Rule On Halting Ohi Reactors

Osaka court set to rule on halting Ohi reactors

An Osaka court is expected to make an imminent ruling on whether to halt the operations of two reactors at the Ohi nuclear power plant in central Japan.

A nearby resident filed a lawsuit in 2017 with the Osaka District Court calling for an injunction to suspend the operations of the No.3 and 4 reactors in Ohi town, Fukui Prefecture.

The plaintiff claims the units are ill-prepared for a major earthquake, putting the lives and livelihoods of nearby residents at risk.

The court has been assessing whether calculations by the plant's operator, Kansai Electric Power Company, on maximum ground motion at the plant are appropriate.

The plaintiff argues that Kansai Electric uses an improper formula in its calculations, and underestimates maximum ground motion.

The company says it makes stricter assessments than necessary for geological fault lengths and the potential scale of seismic motion.

The court's decision is being closely watched, as an injunction would result in the immediate halt of the reactors, which are in commercial operation.
