It is no doubt that Japan has suffered a horrific tragedy and thousands of people may have perished, our hearts go out to them. We people, live in a world where we are unable to hold back the forces of nature and the world has not found any way of forecasting where the next disaster will strike.
It seems an almost impossible task to for the country to clear up the mess and rebuild as before, and as for the families who have lost every thing how on earth do they begin to replace those losses. but they will in due coarse...

Japan warns of small radiation leak at nuclear plant « Reply #13 Posted: 12 March 2011 at 12:09 AM »

Japanese authorities have warned there could be a small radiation leak from a nuclear reactor whose cooling system was knocked out by the earthquake. Technicians at the Fukushima Daiichi plant are set to release vapour from the unit in question to lower the pressure and prevent a meltdown. This carries a risk that a small amount of radioactive material could leak, officials say. The government has ordered about 45,000 people to evacuate the area. Reports quoted Japan's nuclear safety watchdog as saying radioactivity levels in the control room of the Fukushima plant were running at 1,000 times normal. The watchdog also said radioactivity levels near the plant had risen. It was unclear whether the apparent increase in radiation had been caused by the failed cooling system.

Reports also said that cooling systems had also failed in three reactors at a second nuclear power plant, Fukushima Daini, 11km (7 miles) south of Daiichi. A total of 11 reactors at four nuclear power stations automatically closed when the earthquake hit on Friday. The prime minister declared a "nuclear emergency" - under Japanese law, an emergency must be declared if a cooling system fails, if there is a release of radiation, or if there is a dangerous level of water in the reactor.

Japan's nuclear safety agency said pressure inside one of six reactors at the Fukushima Daiichi plant, some 270km north-east of Tokyo, was considerably higher than normal. Authorities say they are taking wind direction into account when planning the release of radioactive vapour, which they insist would not be in quantities big enough to affect human health. "It's possible that radioactive material in the reactor vessel could leak outside but the amount is expected to be small and the wind blowing towards the sea will be considered," Chief Cabinet Secretary Yukio Edano told a news conference.

The reactor at the Fukushima Daiichi power station that triggered the emergency alert was the 40-year-old Reactor 1, one of six on the site. The earthquake cut electricity supplies to the power station, triggering an automatic shut-off for the reactors. Diesel-powered generators kicked in to provide enough power for cooling and other basic functions. But it is understood that at least one back-up generator failed, so causing the cooling system to malfunction. Reactors 1, 2 and 3 automatically shut down when the magnitude 8.9 quake shook the plant, while reactors 4, 5 and 6 were not in operation as they were undergoing scheduled inspections. The reactors are Boiling Water Reactors (BWR), one of the most commonly used designs, and widely used throughout Japan's fleet of nuclear power stations. Heat is produced by a nuclear reaction in the core, causing the water to boil, producing steam. The steam is directly used to drive a turbine, after which it is cooled in a condenser and converted back to water. The water is then pumped back into reactor core, completing the loop.

In total, the country has 55 reactors providing about one-third of the nation's electricity.

There are two nuclear reactors that are in State of emergency

The number of reported dead is rising and many more missing, over the next few days these terrible numbers will unfold

One of the nuclear plant buildings exploded a short while ago. Now confirmed as reactor 1.
Not looking good.

Japan earthquake: nuclear disaster feared after power plant 'explosion'

Japan is battling to avoid a nuclear disaster after an explosion at a power plant in the aftermath of the country’s biggest earthquake and a devastating tsunami.

A huge blast was heard and white smoke seen billowing into the air at one of two power plants which the Japanese government had placed under a state of emergency. Several workers were reported to have been injured.

Prime minister Naoto Kan had warned that a radiation leak might occur at one of the reactors at the Daiichi facility at Fukushima, 150 miles north of Tokyo, after Friday's 8.9-magnitude quake.

The reports of an explosion followed aftershocks and came as a huge humanitarian operation got under way.
By Saturday morning at least 1,300 people were feared dead and international rescue teams began to arrive

The reactor’s cooling system failed after the earthquake struck off the Pacific coast, triggering a 33ft tsunami. Pressure in the reactor was continuing to rise after repeated efforts to return power to the cooling systems failed. Radiation inside the plant soared to 1,000 times its normal level, officials said, triggering evacuation orders for residents.

It looks like a loss of coolant accident. They must now try to prevent a cor melt down. If this happens it will be like a mini volcano spuing high level radioactive molten lava and dust into the atmosphere. I doubt antone will come out and say that. A core meltdown means the very high temperature core will melt everything and travel down into the ground throwing up lots of debri out as it goes.

Latest news is that there has been no damage to the pressure containment vessel. So that is good.
