40R/hr is high, but not insurmountable under the conditions.  Also is that
the general area or only one spot with a high number?  A long section of
piping could be pushed or pulled into place with a crane and fed with pumps
hooked in series.  It seems like a fire truck should be able to lift water
that high.  Certainly if hooked in series (though would the hose hold the

"It is interesting that they have not rigged a hose up to the area and

The dose rates, at one point and for a single measurement, on the ground
between Unit 3 & Unit 4, was 40 REM/hr. Because of the thick concrete
walls in the Unit-4 fuel pool and reactor building, this dose rate is
from skyshine alone!!!

The dose rates on the refuel floor are immediately lethal.

There are systems to remotely fill the spent fuel pool. These must be:
1. damaged
2. without power
3. inaccessible inside the reactor building due to dose rates, and/or
4. fire trucks (cross connected to the normal filling system) cannot
generate enough pressure to push the water to the 4th floor

Probably a combo of items 1,2,&3.
