ol them down and reduce
pressure inside reactor container vessels.
01:43 - Japan Atomic Power says the cooling process was
working at its Tokai No.2 nuclear power plant's reactor although
two of the three diesel power generators used for cooling were
out of order. The reactor at the plant, about 120 km (75 miles)
north of Tokyo in Ibaraki prefecture, was automatically shut
after Friday's massive earthquake and tsunami.
07:29 - TEPCO says it has reported a rise in radiation
levels at its Fukushima Daiichi nuclear power plant to the
11:11 - Domestic media image shows smoke rising from the
No.3 reactor at Japan's Fukushima Daiichi nuclear plant.
Japanese TV says there was a hydrogen explosion at the plant.
11:20 - Japan's nuclear safety agency confirms a new
explosion rocked Japan's stricken Fukushima Daiichi nuclear
power complex, sending a plume of smoke into the air. But it
says it cannot confirm whether or not the hydrogen explosion at
the plant's No.3 reactor has led to an uncontrolled leak of
11:40 - Jiji quotes TEPCO as saying a fresh explosion that
rocked the Fukushima Daiichi nuclear power complex has not
damaged the plant's No.3 reactor vessel.
12:43 - Chief Cabinet Secretary Yukio Edano says a
large-scale radiation leakage is unlikely from the Fukushima
Daiichi nuclear power plant's No. 3 reactor hit by an explosion
after cooling problems.
15:17 - Jiji news agency reports that there has
been an explosion at a fuel oil tank at a thermal power plant in
Fukushima and that the tank is on fire. It is not immediately
clear which company the thermal power plant belonged to.
15:26 - The IAEA says Japan has told the U.N. nuclear
watchdog the hydrogen explosion at the No.3 reactor at the
Fukushima Daiichi nuclear plan did not damage the primary
16:17 - Chief Cabinet Secretary Yukio Edano confirms water
levels at the Fukushima Daiichi plant No.2 reactor are falling
and its cooling functions have stopped.
17:23 - Jiji news agency says Japanese authorities have
safely cooled down two nuclear reactors at the Fukushima Daini
nuclear plant, close to another nuclear complex where they are
still struggling to cool three overheating reactors.
19:52 - Jiji quotes TEPCO as saying nuclear fuel rods at the
Fukushima Daiichi complex's No.2 reactor, where levels of water
coolant around the reactor core had been reported as falling
earlier in the day, are now fully exposed. Jiji says a meltdown
of the fuel rods cannot be ruled out.
20:10 - Water levels inside the Fukushima Daiichi complex's
No.2 reactor are almost empty, TEPCO says. Jiji news agency says
the operator of the plant has started injecting sea water to the
reactor in the hope of cooling it down.
