No. 4 spent fuel pool heating up after cooling system knocked out

Could make these Colorado fires look pretty insignificant.

Note that NBC’s top story tonight was about a college kid who got attacked by chimps in S. Africa. No mention of Fukushima or LIBOR. They’re not even pretending any more.

The cooling system of the spent-fuel pool in reactor 4 at the Fukushima No. 1 plant automatically suspended operations Saturday and the water temperature is starting to rise, Tokyo Electric Power Co. said.

The utility has been unable to activate a backup cooling system for the pool since operations halted at around 6.25 a.m., and is looking into the causes, Tepco officials said later in the day.

The pool’s water temperature stood at around 31 degrees Celsius when the cooling system ceased functioning and was increasing by 0.26 degree per hour late Saturday afternoon, according to the officials.

If Tepco remains unable to start up the system or its backup, the temperature could reach 65 degrees by Tuesday morning — the maximum limit specified by safety regulations.

Reactor 4 demands our attention

Which dude said, Hey, let’s put the spent fuel pool on the roof of the reactor building. Are the US reactors like that as well (except with far more spent fuel)? Ack.

It would be good to remove the material from the spent fuel pool before it all collapses in a heap. Currently the crane is crumpled in the pool itself. So a new crane will be needed, and a structure to support it. Here are the plans for such released today:
