A tour of the facilities five years after the worst nuclear accident since Chernobyl. The damaged reactors have been stabilized through makeshift water cooling and release of radioactive water have been greatly reduced. The ice wall to contain radioactive water from leaking into the ocean has been completed and is awaiting regulator approval to put into operation. Over 100,000 evacuees have been allowed to return. Decommissioning continues and will take decades to complete and cost billions of yen. Plenty of challenges lay ahead. What to do with contaminated soil, water, and how to remove the melted fuel.
