– Engineers successfully lay a power cable outside the damaged Fukushima Daiichi nuclear power station as the first step in an attempt to cool the reactors and stop spreading of radiation.

– Further cabling inside the plant is in progress before trying to start water pumps to cool overheated fuel rods. Plant operator confirms that engineers are able to restart a diesel pump to cool reactor in plant number 5.

– The plant operator states that when the power is restored, all equipment will be checked to ensure that they are working and not damaged before trying to restart coolers at reactor No.2, followed by 1, 3 an 4.

– The U.N. atomic agency says the situation at the power plant is critical but it is not deteriorating badly.

– If engineers were unable to cool the reactor, the last option would be to bury the plant in concrete and sand in order to prevent a catastrophic radiation leak – the method used at Chernobyl in Ukraine in 1986.

– Based on the 7-level INES international scale, the severity rating of Japan nuclear crisis has risen to level 5 from 4, the equivalent of the Three Mile Island accident in 1979. The 1986 Chernobyl in Ukraine was rated 7 on that scale.

– At this stage, Japan has not planned to expand the evacuation area beyond 30 km yet. Radiation level at the plant is reported to be as high as 20 milli-Sieverts per hour. The limit for workers involved in emergencies was previously 100 milliSieverts but it has been raised to 250 for workers battling at Fukushima incident.

– The head of the U.S Nuclear Regulatory Commission, Gregory Jaczko, says that it could take up to several weeks before the reactors are cooled down. About 300 workers, wearing masks, goggles and protective clothing are working strenuously in the radioactive wreckage.

– Japanese Prime Minister, Naoto Kan plans to sound out the opposition party on joining a grand coalition to handle reconstruction policy after the earthquake and tsunami.

– A man was pulled out alive from the rubble of a house eight days after the quake in Miyagi region, one of the most affected areas.

– A death toll of nearly 7,000 people have been confirmed. Another 10,700 people are still missing.

– The Japanese government plans to dedicate up to 10 trillion Yen ($127 billion) lending to businesses to help them in their day-to-day operations and repair damage.
