SENDAI (Kyodo) -- A new sea wall has recently been erected at the Onagawa nuclear power plant in Miyagi Prefecture to guard the seaside complex against possible tsunami and was shown to local assembly members on Tuesday.

The sea wall, built in the wake of the nuclear disaster in nearby Fukushima Prefecture triggered by the March 2011 earthquake and tsunami, is about 3 meters tall, effectively making it a 17-meter sea wall given that it is built on ground about 14 meters above sea level.

The concrete structure, built at the Tohoku Electric Power Co. nuclear power complex in the town of Onagawa and the city of Ishinomaki, stretches about 600 meters along the Pacific coast. It was shown Tuesday to Ishinomaki assembly members in a guided tour.

All operating commercial nuclear reactors in the country have gone offline amid public concern over the safety of nuclear reactors in the aftermath of the disaster at the Fukushima Daiichi nuclear power plant.
