A step in the decommissioning of Japan's crippled Fukushima Daiichi nuclear plant could be delayed by 3 years.
Japan's government and the plant operator say they need more time before they remove spent nuclear fuel rods in 2 of the reactors. The rods are in storage pools and now won't be removed until fiscal 2023. They say they first need to remove rubble and radioactive substances.
The plan to remove molten fuel debris has not changed. This step is considered the biggest hurdle to decommissioning the plant.
The plant went into triple meltdown following the 2011 earthquake and tsunami. It's expected to take 40 years to scrap the plant.
