Kansai Electric Power will begin surveys for the construction of a new nuclear power reactor at its Mihama power station in Fukui prefecture, western Japan, to replace the existing facility, the company said on Tuesday.

A Japanese power company unveiled plans for the country’s first nuclear reactor since the 2011 Fukushima meltdown.

The Tokyo Electric Power Company Holdings said it will need 12 to 15 years of preparation – or until 2037 or later – before starting the full-scale removal of melted fuel debris.
