SHIZUOKA —The Hamaoka nuclear plant locate din Shizuoka Prefecture is unlikely to be restarted anytime soon, the prefecture’s governor said Monday.
The aging nuclear plant is located near a faultline in a region seen as vulnerable to earthquakes. It was one of the first nuclear plants ordered to be shut down after last year’s March 11 disaster.
Last September, plant operator Chubu Electric Co began preparations to build an 18-meter-high anti-tsunami seawall.
However, Shizuoka Gov Heita Kawakatsu told reporters that new disaster-mitigation measures at the plant are a long way off, NTV reported.
Chubu Electric says the seawall and other additional safety measures should protect the plant from a tsunami as strong as the one that crippled the Fukushima plant on after the March 11 earthquake.
The Hamaoka plant faces the Pacific Ocean and sits in the Tokai region, southwest of Tokyo, where seismologists have long warned that a major quake is overdue because two major continental plates meet here.
Chubu Electric said it will spend about 100 billion yen on the 1.6-kilometer-long wall, as well as other measures to prevent flooding inside the plant, and programs to safeguard cooling systems that bring reactors to safe shutdown in case of severe accidents.
Before it shut down, the five-reactor Hamaoka plant accounted for almost 12% of the output of Chubu Electric, which serves a large part of Japan’s industrial heartland, including many Toyota auto factories.
