Ok … so is this latest report in the newspapers (SMH) accurate or not ?

Quote:
Fears of a meltdown at one of the troubled nuclear reactors in Japan have grown after officials said its fuel rods were "fully exposed", as the country grappled with a growing humanitarian and economic crisis after Friday's devastating earthquake and tsunami.

Air pressure inside the No.2 reactor at the Fukushima Daiichi plant, located 250 kilometres north of Tokyo, rose suddenly when the air flow gauge was accidentally turned off, its operator Tokyo Electric Power Company (TEPCO) said.

Cooling water was blocked from flowing into the reactor, leading to full exposure of the rods at about 11.00pm on Monday (1.00am AEDT on Tuesday). When the rods are exposed and temperatures rise within the containment vessel, the rods could lose their vertical shape and melt down.

"We are not optimistic but I think we can inject water once we can reopen the valve and lower air pressure," a TEPCO official told reporters.
Full exposure of the rods is a major issue … something to be very worried about.

Cheers
