The head of the U.S. Nuclear Regulatory Commission (NRC) said all the water is gone from one of the spent fuel pools at Japan’s Fukushima nuclear complex. It increases possibility of nuclear crisis.

“There is no water in the spent fuel pool and we consider that radiation levels are extremely high,” NRC Chairman Gregory Jaczko said, RBK reports.

However, Japanese authorities denied the pool was dry.

As Armenian News-NEWS.am reported earlier, on March 11, the biggest earthquake (9 magnitude) in the recent years hit the northeast of Japan, triggering a 10-meter tsunami and followed by several powerful aftershocks. The epicenter is located 373 to north-east from Japan’s capital, Tokyo at the depth of 24 kilometers. A massive earthquake damaged cooling functions of the Fukushima nuclear plant, making the operator to pour seawater into reactors and let out radioactive air into atmosphere.
