The nuclear power plant Fukushima I under the danger of destruction. The Japanese media informs that the situation at the nuclear power plant is very dangerous. Experts say the full meltdown of nuclear fuel may happen and in this case the consequences would be fatal.

Tokyo Electric Power Company is taking measures to reduce pressure inside the No.1 reactor containment vessel at the troubled Fukushima Daiichi nuclear plant.

The power company began injecting more water into the No.1 reactor on Wednesday, after temperatures on the reactor surface reached about 400 degrees Celsius, exceeding the safety limit of 302 degrees.

The power company says lights have been turned on inside the control room of the No.1 reactor building.

Japan's Nuclear and Industrial Safety Agency says the influx of massive amounts of water has raised the pressure inside the reactor containment vessel.

The power company cut back on the water injection early on Thursday. This resulted in pressure inside the container dropping to 0.3585 mega-pascals, below the safety limit of 0.528 mega-pascals.

The reactor temperature also dropped to 243 degrees as of 5:00 AM on Thursday.

The safety agency says the reactor remains stable for now, but it will continue monitoring it carefully.

Chief Cabinet Secretary Yukio Edano said on Thursday there has been no damage to the containment vessel of the No.1 reactor despite the rise in pressure inside. He also said that it is necessary to monitor the situation continuously.
