#Fukushima I Nuke Plant: It Will Take Years, Says Nuclear Safety Commission

in order to cool the fuel rods in the reactors and the spent fuel rods. Years. They are saying 1 to 2 years just to restore the water circulation systems.

From Jiji Tsushin's article (3/29/2011) on March 29 press conference by Nuclear Safety Commission, whose chairman by the way may be in trouble for being too "candid", embarrassing the politicians:

It will take years to cool the fuel rods in the reactors and the spent fuel rods at Fukushima I Nuclear Power Plant.

When the power is cut off, the heat from the fuel rods would drop to a few percent of the heat during the normal operation and would further drop to 1 percent within 1 to 2 weeks. But after that, it wouldn't decrease very much. Therefore, the heat exchanger systems need be restored.

The pumps to draw sea water are broken, and it will take months till the replacement pumps arrives. The circulation systems must be restored within 1 to 2 years.

In order to store the water polluted with radiation, the plan should be made for storage ponds and pools.

Regarding the Reactor Pressure Vessels (RPVs) of the Reactors 2 and 3, it is natural to assume that there is a leak somewhere when the pressures do not rise as expected. The Commission suggests the possibility that the RPVs are broken.
