TEPCO forced to review reactor 4 cooling plan, NHK, June 12, 2011:
The operator of the Fukushima Daiichi nuclear power plant has been forced to reconsider its plan to cool the spent fuel storage pool of the No.4 reactor.
Water injection from a special vehicle has not been intense enough to cool the water in the pool [...]
On Friday, workers entered the 4th floor of the No.4 reactor building where the pool is located for the first time since the nuclear disaster took place.
They found a large hole in a wall created by the March 15th explosion. They also discovered that a nearby pipe necessary for the cooling system had been mangled. [...] Fixing the damaged pipe is expected to be extremely difficult. [...]
