Chubu Electric Power plans to construct an 18m-high tsunami defence wall around the around the Hamaoka nuclear plant in Japan.
Construction of the wall, which will stretch 1.6km around the plant, is estimated to cost around JPY100bn ($1.3bn).
The company will also take preventive measures to ensure water does not enter the nuclear facility and enable the plant to sustain an earthquake of the same magnitude as the 11 March 2011 disaster.
Construction of the tsunami defences are expected to be completed by December 2012, reports Reuters.
The Hamaoka nuclear plant was closed in May after the Prime Minister Naoto Kan called for its shut down, citing that the region is at risk of being hit by another major earthquake in next few decades.
