Good explanation of the technology at Fukushima, but doesn't explain the apparent lack of batteries.
Although Tokyo Electric said it also continued to deal with cooling system failures and high pressures at half a dozen of its 10 reactors in the two Fukushima complexes, fears mounted about the threat posed by the pools of water where years of spent fuel rods are stored.
At the 40-year-old Fukushima Daiichi unit 1, where an explosion Saturday destroyed a building housing the reactor, the spent fuel pool, in accordance with General Electric’s design, is placed above the reactor. Tokyo Electric said it was trying to figure out how to maintain water levels in the pools, indicating that the normal safety systems there had failed, too. Failure to keep adequate water levels in a pool would lead to a catastrophic fire, said nuclear experts, some of whom think that unit 1’s pool may now be outside.
“That would be like Chernobyl on steroids,” said Arnie Gundersen, a nuclear engineer at Fairewinds Associates and a member of the public oversight panel for the Vermont Yankee nuclear plant, which is identical to the Fukushima Daiichi unit 1.
The fuel rods in the No.2 reactor at the quake-damaged plant are again "fully exposed", boosting fears of an eventual partial meltdown.
Air pressure inside the reactor at the Fukushima No 1. plant rose suddenly when the air flow gauge was accidentally turned off, operator TEPCO said early Tuesday (local time).
That blocked the flow of cooling water into the reactor, leading to full exposure of the rods about 11pm on Monday, it said.
Reminds me of the generators in the basements of hospitals in New Orleans when Katrina struck.
