A state-backed entity is close to completing a plan for decommissioning the crisis-hit Fukushima nuclear power plant, detailing for the first time how it hopes to extract fuel debris from three reactors, sources said.

The Nuclear Damage Compensation and Decommissioning Facilitation Corp., tasked with providing technical support for decommissioning the complex, may propose a method to remove nuclear debris without completely filling the reactor containment vessels with water, the sources said Tuesday.

The plan means the debris inside reactors 1, 2 and 3 at the crippled Fukushima No. 1 complex is likely to be shaved off gradually with a drill or laser equipment as a shower of water is poured remotely, the sources said.
