Completion of Hamaoka plant tsunami seawall delayed
SHIZUOKA — Chubu Electric Power Co said Tuesday that it will complete the construction of a tsunami seawall around its Hamaoka nuclear power plant in Shizuoka Prefecture by December next year, which is later than originally planned.
The power utility initially planned to build a 18-meter-high seawall but this was judged not high enough. The 1.6-kilometer-long seawall will now be 21 meters high. Chubu Electric said a coastal levee will also take longer to construct, TBS reported.
The Hamaoka plant lies just 100 meters away from 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.
