One Reactor Damaged, Radiation Threat Back

The damaged reactor contain radioactive fuel as much as 170 tons.

One reactor at the Nuclear Power Plant (NPP) Fukushima Daiichi, Japan, allegedly suffered damage. It is feared would spread radiation at a rate more into the air.
As reported by the page the Associated Press, Friday, March 25, 2011, a spokesman for Japan's nuclear safety agency, Hidehiko Nishiyama, said that there is data showing the singularity in the function of the reactor at nuclear power plants. "Probably one of the reactor were damaged," Nishiyama said.
He said that it is likely that the reactor is damaged reactor unit three, which exploded on Monday, March 14, 2011. Reactor unit is the most problematic since the nuclear crisis occurred in Fukushima. Accommodate the radioactive fuel as much as 170 tons, the damage can be fatal.
So far, the radioactive deliberately set their spending by the team to reduce the pressure in the sheath. If the damaged reactor, it is feared uncontrolled spending becomes radioactive and can distribute large amounts of radiation into the air.
Work on the reactor is stopped when done checking reactor units at the nuclear power plant.
Meanwhile, efforts to cool the reactor by pumping sea water into the reactor casing is feared hampered due to deposition of salt crystals in water distribution channel.
Reporting from the CNN pages, which settles the salt crystals from sea water flowed into reactor. When sea water evaporates due to heating in the sheath of the reactor, the salt left behind at the bottom. It is feared could cause damage or even the warming of the temperature inside the envelope.
Nuclear experts from the University of Michigan, Gary Was, says that if salt buildup in the reactor will not be a problem. However, if the sediment in the water hose supplier, is likely to inhibit the rate of sea water. "If it settles in the reactor core, it will not be a problem. Because the salt will melt with the temperature is very hot inside," he said.
Sea water is a major tool in the effort to cool the nuclear reactor in Fukushima. Post-earthquake and tsunami two weeks ago, officers using sea water with injected directly into the reactor, or through water cannon spray or poured through a helicopter. In one minute, 100 gallons of water channeled into each reactor at this nuclear power plant.
