Asia Bizz: Despite being declared stable, water leaks from the crippled Fukushima Daiichi nuclear power plant in Japan have become more frequent. Last year, a massive earthquake and tsunami badly damaged the power plant which resulted in the meltdown of three reactor cores.

The Tokyo Electric Power Co. is constantly facing challenges to keep the nuclear power plant under control. On February 3, 2012, the workers spotted a leak at the water processing unit that was releasing beta rays that could cause radiation sickness.

The spokesperson of TEPCO said that no one was injured and the leaks stopped as soon as the bolts were tightened on a tank. It was also revealed that 8.5 tons of radioactive water leaked earlier in the week.

The water leaked as the pipe became detached at No 4 reactor which is one of the six reactors at the plant. Earlier the company claimed that only a few litres of water leaked out. The officials are now investigating the exact cause of leak. The damage of the no 4 reactor building has been a cause of concern to the experts due to the collapse of its spent fuel cooling pool that could cause a major disaster. Due to the cold winter the water inside the plant has frozen.
