Radiation has work in the Japanese nuclear power plant

Workers fought for disaster today in a highly competitive Japanese nuclear plant preempt self-described earthquake aftershocks and a radiation spewing at the site of fire rattled the nation.

An evacuee is screened on Tuesday for an uncontrolled in Koriyama, Fukushima, Prefecture.
On the fifth day of the crisis in the Japanese prefecture Fukushima Dai-Ichi nuclear plant, northeast of Tokyo, the Islands earthquake and a tsunami, recovered from Friday magnitude 9.0 which killed thousands of people."Reactors have the plant again and again small amounts of radioactive gas in the crisis, which release ventilated result of the intentional movements of pressure in the reactors."There is still a very high risk for more radiation coming out "warned Japanese Prime Minister Naoto Kan Tuesday.The two hours fire on Tuesday on the plant reactor buildings in a water pool it apparently heated verwendet-Up nuclear fuel rods kept." That triggered the release of radioactive steam more than 160 times the annual dose received course one person short spiked heel radiation levels after a year.A second fire broke this morning in the same building. Tokyo electric power spokesman Hajimi Motujuku said the blaze exterior of reactor containment vessel broke out.Tokyo electric power, said the new blaze broke out, because the first fire had not completely extinct.The plant as spraying water and acid of helicopters and Firetrucks in his troubled nuclear reactors to prevent further a radiation of Leaky, Masami Nishimura, a spokesman for Japan nuclear Sicherheitsagentur.Hohen radiation levels said prompted an evacuation of the plant Tuesday, pouring sea water left 50 employees in three overheating reactors continue."They had operations suspend this morning after an increase in the radiation made too dangerous for the workers continue to set up, Chief Cabinet Secretary said Yukio Edano."The workers even the smallest work now to perform the work, "he said." "Because of the radiation hazard, we are on stand by mode."The most worrying, a reactor was an earlier explosion at the site showing signs of leaks to. Such a leak in the steel and concrete containment vessel, the houses the nuclear core of a reactor the biggest threat of a "radiological event" in the crisis, said Anthony Pietrangelo of the nuclear energy Institute, an industry organization in WashingtonD.C.The Dai-Ichi plant had its three operating nuclear reactors automatically stopped, when the earthquake hit Friday, but the tsunami still hot nuclear fuel rods knocked out cooling of the system.Pietrangelo compared the crisis 1979's three mile Iceland disaster, in which about half of the nuclear fuel in a reactor melted down.In an effort to prevent a similar fate for the installation of three working reactors - all probably with partially molten fuel rods - cast engineers in sea water.Japanese officials Tuesday indicated that water levels in two of the reactors seem stable but are on the reactor shakily signs of a leak. "To keep cool the fuel rods the key is to prevent a major meltdown and large amounts of radiation."You are working with razor-thin margins, "said nuclear expert David hole tree from the Union of concerned scientists against building more nuclear power plants." Hydrogen explosions at the site have injured 15 workers and the outer housing all three reactors building damaged.In a last desperate step sea water cools the rods, the the water, creating steam boiling. The steam must be drained release to pressure on the reactor Chamber. "More water can be added, to keep the bars immersed."Sea water is not what normally would like to use for this operation "Engineer of Brian Woods said Oregon State University in Corvallis the nuclear."As long as is to keep the sea water, cool things, but should it released relatively little radioactive gas, "Woods said.
