QWhat will become of Fukushima Daiichi Nuclear Power Station?
AWork is underway to decommission the reactors within 30-40 years.

Due to the failure of reactor cooling, the nuclear fuel overheated and melted together with peripheral metals, etc., and the resulting materials later cooled and hardened to become "fuel debris". Following the accident at TEPCO's Fukushima Daiichi Nuclear Power Station, Reactors 1-3 still contain fuel debris, however, the reactors are being maintained in a stable condition by continuously pouring water.
