No.2 reactor chronology
Three of the 6 nuclear reactors at the Fukushima Number One nuclear power plant automatically halted operations at 2:46 PM on Friday after the earthquake struck. But the emergency power generator to cool the reactors failed to work.Tokyo Electric Power Company notified the government that a state of emergency existed based on laws governing nuclear issues. The government then instructed nearby residents to evacuate. At the No.2 reactor, the cooling water had partially evaporated, considerably reducing the water level inside the nuclear containment vessel.Two days after the earthquake, on Sunday, the pressure rose. To prevent the container from being damaged, work began to release the inside air which includes radioactive substances.
But on Monday, the pressure increased further, and the water level also dropped. TEPCO began to pump in sea water on Monday afternoon. But the pump ran out of fuel and the water level remained low. The 4 meter tall fuel rods are believed to have been fully exposed for 2 hours and 20 minutes.
Shortly after 9:30 PM, high levels of radiation measuring 3,130 microsieverts per hour were recorded near the plant gates. It is believed that the fuel rods were likely damaged and melted. At around 6:10 Tuesday morning, an explosion was heard near a facility known as the suppression pool, which adjusts the pressure of the No.2 reactor.
At one point immediately after the explosion, radiation levels near the power plant reached 965.5 microsieverts.
The facility is believed to have sustained damage, and radioactive substances are unlikely to have been sufficiently contained.
No.3 reactor chronology
Immediately after the earthquake, water was pumped into the No.3 nuclear reactor of the stricken Fukushima plant to prevent overheating. But 2 days later, on Sunday, the system to provide water stopped operating and an emergency was declared. The pressure in the reactor's containment vessel rose while the water level dropped, leaving some of the fuel rods exposed and possibly damaging and causing them to melt. So work began to pump sea water into the reactor, but the operation was suspended due to a lack of water. Shortly after 11:00 AM on Monday, the hydrogen which had accumulated inside the No.3 reactor exploded, blowing away the ceiling and outer walls.
Eleven TEPCO employees and Self Defense Force members were injured.

No.4 reactor chronology
The No.4 reactor at the Fukushima No.1 nuclear power plant had been shut down for regular inspection since November last year. There was no nuclear fuel in the reactor, and its 783 fuel rods had been removed to a pool for spent nuclear waste. The pool's temperature more than doubled to 84 degrees Celsius as of 4:18 AM on Monday after its cooling system broke down. An explosion occurred at around 6:00 AM on Tuesday. The roof of the No.4 reactor building was found to have been damaged. At around 9:00 AM, a fire was confirmed in the reactor building. The plant's operator promptly issued an emergency alert. The fire was later put out, but a radiation level of 100 millisieverts per hour was detected around the reactor building at 10:22 AM on Tuesday.
Fire at No.4 reactor put down
Tokyo Electric Power Company says the fire has been extinguished at the No.4 reactor at the quake-hit nuclear power plant in Fukushima prefecture. Company officials said that the fire had started at 9:38 AM local time on Tuesday near the northwestern part of the 4th floor of the building that houses the reactor at the Fukushima No.1 nuclear power plant. The officials said before the fire, an explosion was heard and that an area near the roof of that building was found to have been damaged. TEPCO is confirming reports that the temperature of the pool which contains spent nuclear fuel had risen from its usual 40 degrees Celsius to 84 degrees.A company official says a hydrogen explosion is thought to have occurred at the No.4 reactor, but details including its relation to the fire are unknown. Chief Cabinet Secretary Yukio Edano told reporters shortly after 11:00 AM on Tuesday that a fire had broken out at the No.4 reactor. He said the reactor has not been operating after the earthquake, but hydrogen is being produced because spent fuel creates its own heat. He said so it can be inferred that a hydrogen explosion similar to those that took place at the No. 1 and 3 reactors occurred.
All residents within 20km of plant evacuated
Japan's National Police Agency says all residents within 20 kilometers of the quake-damaged Fukushima No.1 nuclear power plant have been evacuated. Police and Self-Defense Forces personnel guided the residents to safety following reports of radiation leaks from the plant's reactors. They worked overnight to relocate 450 hospital patients and nursing home residents by bus, and the last 96 hospital patients were flown to safety by helicopter on Tuesday morning. Police cars are patrolling areas between 20 and 30 kilometers of the plant and urging residents to stay indoors with their windows shut.Tuesday, March 15, 2011 16:05 +0900 (JST)
