This picture taken on August 21, 2010 shows members of the Fukushima prefectural assembly observing an operation of the MOX fuel storage pool inside the Tokyo Electric Power CO's (TEPCO) Fukushima No.1 plant third reactor building in the town of Okuma, Futaba district, in Fukushima prefecture. Four of the six reactors at the Fukushima No.1 plant have now overheated and sparked explosions since a massive earthquake and tsunami knocked out cooling systems on March 11, 2011. Radiation levels near a quake-hit nuclear plant are now harmful to human health, Japan's government said on March 15, 2011 after two explosions and a fire at the crippled facility.
