In a nationally televised statement Tuesday, Prime Minister Naoto Kan said radiation has spread from the three reactors of the Fukushima nuclear plant after Friday's massive earthquake and resulting tsunami. Mr. Kan said the radiation level is very high and he said there still is a very high risk of more radiation coming out. There was a third explosion Tuesday morning at the Fukushima plant following similar blasts on Saturday and Monday. And officials say a fire has broken out in one of the plant's reactors. No casualties are reported at the plant.
The troubles began when the earthquake and tsunami knocked out power on Friday, crippling the cooling systems needed to keep nuclear fuel rods from melting down. On Monday, the U.S. Geological Survey upgraded the magnitude of the quake to 9.0 from the previous estimate of 8.9. There have been numerous aftershocks since the initial quake.
Engineers have been pumping seawater into the Fukushima plant to cool the fuel rods after a steam vent inside one of its reactors closed for an unknown reason. But the water levels dropped too abruptly and officials say the fuel rods have been exposed to air at least twice so far. Some of the rod casings may have melted in the heat, allowing contaminated gases to leak into nearby areas. Plant officials say that some radiation has been detected outside the plant. U.S. warships and planes helping with relief efforts moved away from the coast temporarily because of low-level radiation.
Almost 200,000 people have been evacuated from areas around Fukushima. The government has advised those who remain at home to keep indoors. Residents in quake- and tsunami-hit regions are suffering from food, water and heat shortages. Many homes are without electricity and running water. The official death toll has reached almost 2,000, but authorities say they have not been able to contact about 10,000 other people, and that new bodies are constantly being washed ashore. Power rationing began Monday across Japan. That is expected to last into April as the demand for electricity is expected to exceed supply.
About 100,000 Japanese troops, backed by relief teams from more than a dozen countries, are searching for survivors in the rubble. Two U.S. search-and-rescue teams with 144 staff and 12 dogs, are among the teams that began clawing through the ruins at first light Monday in search of survivors. A 15-member Chinese team also was at work. Japan's Kyodo news agency said the Defense Ministry will activate reserves to assist in relief operations, the first time it has done so.
