Fire engines

Can't find the link right now, but that is apparently how they are pumping the water in. It's also why one of the cores ended up getting uncovered: the pumper ran out of gas. The fire suppressing pumps of the turbine halls are also being used but some of those have been damaged by the explosions.

The worry is that they may not be able to source enough diesel to keep the pumps going due to the broken supply chain and shortages elsewhere.

Yup.

http://english.chosu...011031500630.html

When the cooling system at the reactor broke down, TEPCO used fire engines to pump seawater into the reactor to cool the rods, but the pump malfunctioned, causing most of the fuel rods to be exposed. If exposed to air, fuel rods overheat and melt, releasing radioactive materials into the atmosphere.

TEPCO said it cannot rule out a meltdown due to the exposure of the fuel rods but is bringing the temperature down again by injecting seawater. It added since the reactor is contained by an outer structure there is "no possibility of a worst-case accident."

Japanese broadcaster NHK reported the pumps stopped flushing seawater into the reactor after running out of fuel when a plant official who was operating the pumps left his seat to monitor something else.

(I'd be surprised if it really came down to one person getting up to go to the toilet (or whatever).)

NHK has an English page with information that is probably more timely than the big English news sites - http://www3.nhk.or.jp/nhkworld/

Cheers,
Scott.
