The recommendation for a barrier, which the government is now planning to install, was made by US experts just three months after the plant was severely damaged in the 2011 earthquake and tsunami.
However, at the time, Tokyo Electric Power Company (Tepco), operators of the plant, successfully lobbied against the proposal due to high costs and fragile investor confidence, according to a memo uncovered by a Japanese newspaper.
News of Tepco’s rejection of the proposed barrier comes only weeks after Shinzo Abe, the prime minister, unveiled plans to build a frozen wall to limit such leaks, in the run up to the Olympic 2020 bid announcement.
Operators of the Fukushima plant, which Mr Abe is visiting today on an official tour, recently reversed months of denials and admitted that hundreds of tonnes of radioactive water was leaking from the hastily-constructed storage tanks every day.
