Japan’s government approved a revised “road map” yesterday to clean up the Fukushima nuclear power plant destroyed by an earthquake and tsunami in 2011.

Decommissioning the damaged reactors is expected to take 30 to 40 years.

The three reactors that had meltdowns have a combined total of 1,573 units of mostly used nuclear fuel rods, which are still inside and must be kept cool in pools of water.
