Chubu Electric Power will construct a 16 kilometer long, 18 meter high tsunami defence wall around its Hamaoka nuclear plant in Tokyo at an estimated cost of around JPY100 billion or $1.3 billion.
The company will also take safety measures to avoid the entry of the water into the nuclear facility and to ensure that the plant will be able to withstand even if another earth quake of the 9.0 magnitude like11 March 2011 occurs in future.
Construction of the tsunami deference wall is slated to be completed by December 2012.
The company had to close the plant in May after the Prime Minister Naoto Kan called for its shut down stating that the region, where the plant is located is prone to a major earthquake in next few decades.
