Debris And Contaminated Water Still Fill No.4 Reactor Building Of Fukushima Daiichi

OKUMA, JAPAN - JANUARY 29: Radiation-contaminated water floods the basement of the No.4 reactor at Tokyo Electric Power Co (TEPCO)'s Fukushima Daiichi Nuclear Power Plant on January 29, 2014 in Okuma, Fukushima, Japan. The No. 4 reactor of the srtricken Fukushima Daiichi Nuclear Power Plant where workers are removing spent nuclear fuel, is still a gutted shell and conditions there remain extremely hazardous, even though the No. 4 reactor has seen the most decommissioning work of those four reactors as radiation levels there are much lower than in the other reactors.
