The president of Tokyo Electric Power Company Holdings Inc., the operator of the Fukushima No. 1 nuclear plant, has vowed to responsibly scrap the crippled reactors and revitalize the economies of its host communities, ahead of the 10th anniversary of the accident.

In a recent online interview, Tomoaki Kobayakawa said the utility was "making all-out efforts" in the decommissioning work and to achieve economic revitalization for the local communities. He also said radiation levels at the crisis-hit plant remain relatively stable.

Inside three of the Fukushima No. 1's six nuclear reactors, however, melted fuel debris remains highly radioactive, leaving decommissioning a challenging task even 10 years after the world's worst nuclear disaster since the 1986 Chernobyl accident.
