TOKYO, Aug. 5 — RIA Novosti, Xenia Naka.For the first time after the March accident temperature in the third reactor nuclear power plant "Fukushima-1" has dropped below 100 degrees Celsius, the company said the operator station Thurso.
On September 1, Petersen applied for reactor cooling system further spraying water on the principle of the soul and believes that it was the most effective.
In the first reactor was possible to reduce the temperature to 90 degrees. However, for the full stop of the reactor need for analysis and calculation of possible radiation leaks, so Petersen said the decision premature.
Stabilization of the temperature below 100 degrees — one of the most important conditions for the transition to a reactor shutdown. Petersen also said it intends to apply the method of cooling spray, which had shown its effectiveness, and in the second reactor.
Stopping the supply of electricity due to the earthquake and tsunami on March 11 led to the melting of fuel on the ground — the third reactor nuclear power plant "Fukushima-1", and experts with certainty say that nuclear fuel is likely to not only melted rods, but burned the bottom of the reactor vessel and accumulated at the bottom of the reactor containment.
According to experts, in order to extract nuclear fuel and reactors permanently eliminate the consequences of the accident, will take several decades.
