Japanese authorities have yet to confirm the overflow of radioactive water from the emergency units of Japanese nuclear power plant Fukushima 1, the Kyodo news agency reported on Tuesday, according to RIA Novosti.
The 9.0-magnitude earthquake and tsunami that rocked Japan on March 11 triggered a number of explosions at the Fukushima nuclear power plant, spreading fears of massive radioactive contamination.
The reactors are located some 55 to 70 meters away from the Pacific coast.
Chief Cabinet Secretary Yukio Edano admitted on Tuesday that there was a partial meltdown of fuel assemblies at Fukushima`s reactor No. 2.
On Monday, the plant operator Tokyo Electric Power Co. detected plutonium in the soil of the Fukushima plant. However, according to experts, the concentration of the substance does not differ from previous recorded analysis and poses no threat to human health.
Greenpeace suggested on Monday extending the evacuation zone around the plant from 20 to 40 kilometers due to high radiation levels.
The confirmed death toll from the earthquake and tsunami stands at more than 10,000, according to police, and over 17,440 are listed as missing.
