Japanese army helicopters able to pour a large amount of water on Thursday morning on two of the reactors at the Fukushima nuclear power to try to cool the fuel, which threatens to enter merger, according to images broadcast live on public television NHK. Apparatus, type CH-47 Chinook, flying over the central and four times seven poured 500 liters of water over the damaged reactor three and four, according to the images.
Currently there are no reports on the outcome of the operation. The plant, operated by Tokyo Electric Power Company (TEPCO), has accumulated a string of serious problems from the earthquake followed by tsunami on Friday. This maneuver aims to prevent spent fuel from the reactor four, currently out of the water is extremely dangerous and cause a major accident.
The reactor containment enclosure three is probably corrupted. On Wednesday abandoned an attempt to use helicopters to cool the reactors due to very high levels of radioactivity. The authorities also plan to use on Thursday, a tanker with water cannons to water reactor four. A special truck Tokyo municipal police arrived Wednesday night near the site to implement this technique, as yet, unpublished.
The radiation level detected in the plant operated by Tokyo Electric Power Co. Fukushima has fallen steadily over the past 12 hours, an official said Thursday Agency's Nuclear and Industrial Safety in Japan. There was a level of 752 microsieverts per hour at the main gate of the plant at 17:00 local time (08:00 GMT) on Wednesday, the official said Tetsuo Ohmura.
Then they changed the location of monitoring at the door on the west side of the plant and records were taken every 30 minutes, he said. At 05:00 am on Thursday, the reading indicated 338 microsieverts per hour. That level is still much higher than it should, but not dangerous.
