Decision on Japan nuke plant fault line postponed

November 04, 2012


Experts have postponed a decision on whether a fault line underneath Japan's only operating nuclear power plant is active or what to do with the facility.

A five-member team commissioned by the Nuclear Regulation Agency inspected the Oi nuclear power plant in western Japan last week to examine a suspected fault line there.

Two of Oi's four reactors resumed operation in July for the first time since last year's nuclear crisis triggered by a quake and tsunami that hit other reactors in Fukushima No. 1 nuclear power plant in Fukushima Prefecture.

The experts agreed on Nov. 4 that part of Oi's underground structure slid as far back as 125,000 years ago but couldn't tell if it was because of an active fault line. They will meet again this week.

Chief regulator Shunichi Tanaka has suggested a plant closure if the fault line is judged active.
