But some residents have decided never to return because they fear radiation, have built new lives elsewhere or don't want to go back to where the disaster hit.
Media reports in said the government could start to release the water - filtered to reduce radioactivity - into the Pacific Ocean as early as next year. Some scientists believe the huge ocean would dilute the water and that it would pose a low risk to human and animal health. Environmental group Greenpeace however said that the water contains materials that could potentially damage human DNA. Officials have said no final decision has been taken about what to do with the liquid.
Japan nuclear disaster residents return. Fukushima water could damage DNA, Greenpeace says. Five remarkable stories of Japan's tsunami debris. Diving into the world of the dead. Fukushima: Is fear of radiation the real killer? Image source, Reuters. The earthquake was the most powerful ever recorded in Japan. Where is the plant?
What happened at Fukushima? Image source, Getty Images. The tsunami overcame the sea wall and hit the plant. The damage led to nuclear meltdowns and a number of hydrogen explosions. How many people were hurt? Fukushima exclusion worse than radiation? Fukushima's long road to recovery Growing crops in the shadow of Fukushima. Authorities screened civilians for radiation exposure in the wake of the disaster. Chernobyl: What happened thirty years ago?
Chernobyl: The end of a three-decade experiment. Who was at fault? The disaster prompted a wave of public anger and a move away from nuclear power in Japan. In addition, 9 T of low-level contaminated water was discharged from the Central Radioactive Waste Disposal Facility to the south discharge point.
Nitrogen gas is being injected into the Unit 1 containment vessel to reduce the possibility of hydrogen combustion within the containment vessel. The pressure in this containment vessel is increasing due to the addition of nitrogen.
Since 6 April, TEPCO has been moving debris from Units 1 to 4 to a common storage area on-site using remote controlled heavy equipment. On 10 April additional anti-scattering agent was sprayed in an area of about m2 on the mountain-side of the Common Spent Fuel Pool to prevent the radioactive materials on the ground from being scattered. In Unit 1 the pressure in the RPV is increasing, as indicated on both channels of instrumentation.
The temperature at the bottom of the RPV was not reported. Fukushima: A closer look — A worker carries his belongings as he walks among the temporary housing structures at J-Village. Fukushima: A closer look — A deserted field and buildings inside the contaminated exclusion zone around the crippled nuclear power station are seen through the bus window. Fukushima: A closer look — A deserted neighborhood inside the contaminated exclusion zone is visible through the bus window.
March 11, - At p. The earthquake causes a tsunami with foot waves that damage several nuclear reactors in the area.
It is the largest earthquake ever to hit Japan. Number of people killed and missing. Read More. The combined total of confirmed deaths and missing is more than 22, nearly 20, deaths and 2, missing. Deaths were caused by the initial earthquake and tsunami and by post-disaster health conditions. Other Facts. A microsievert mSv is an internationally recognized unit measuring radiation dosage.
People are typically exposed to a total of about 1, microsieverts in one year. The debris was not considered to be radioactive. All times and dates are local Japanese time. About an hour after the quake, waves up to 30 feet high hit the Japanese coast, sweeping away vehicles, causing buildings to collapse, and severing roads and highways.
Sixty to seventy thousand people living nearby are ordered to evacuate to shelters. March 12, - Overnight, a 6. Officials report the earthquake and tsunami have cut off the plant's electrical power, and that backup generators have been disabled by the tsunami. March 13, - People living within 10 kilometers 6. The total evacuated so far is about , So far, three units there have experienced major problems in cooling radioactive material.
The residents remaining within 30 kilometers of the plant, despite an earlier evacuation order, have been ordered to stay indoors. Officials quickly work to pump seawater into the reactor, as they have been doing with two other reactors at the same plant, and the situation is resolved. Workers scramble to cool down fuel rods at two other reactors at the plant - No. Downtown Tokyo is not included. Up to 45 million people will be affected in the rolling outages, which are scheduled to last until April.
March 15, - The third explosion at the Daiichi plant in four days damages the suppression pool of reactor No.
