The most recent radioactive leak at Fukushima nuclear power plant was raised by All Japan news’s Nuclear Regulation Authority (NRA) to Level 3 on an international scale for radiological releases.
In March 2011, Fukushima Daiichi power plant was hit by a disastrous earthquake and tsunami that led to the meltdown of three nuclear reactors. Those meltdowns were classified as Level 7, the highest rating that International Nuclear and Radiological Event Scale (INES) can give.
Last week, Tokyo Electric Power Company (TEPCO), the operator of Fukushima nuclear power plant, reported a new leak, with around 300 tons of radioactive water spilling into the ground. It is the most recent incident in a series of embarrassing revelations related to the crippled power station.
It is still not known since when is the water leaking, nor if the contaminated content has reached the Pacific Ocean or not. TEPCO doubts the radioactive water has reached the ocean, as the tank is located far from the harbor and as no high radiation levels were detected in the water trench located close to the radioactive water tank, according to the company officials.
The NRA has reported last week that it is possible to raise the severity of the leaking from a Level 1 “anomaly” to a Level 3 “serious incident” on the INES scale, after consultations with the International Atomic Energy Agency.
