2006: Three to four new power supply cars have arrived at the Fukushima-Daiichi nuclear plant in north-eastern Japan to provide emergency electricity for the earthquake-damaged cooling system of one reactor, the World Nuclear Association has said. The power cars are being prepared for connection, the WNA said, citing the Japanese ministry of economy, trade and industry. Other power modules are being flown in.
2009: The World Nuclear Association said pressure inside the containment of Reactor 1 at Fukushima-Daichi had been steadily increasing over the time that its emergency core cooling systems had not been active. The Tokyo Electric Power Company reported at 0200 local time (1700 GMT) that pressure had increased beyond reference levels, but was within engineered limits, the WNA added.
