Foundation in Fukushima nuclear plant reactor likely badly damaged

The internal wall of a cylindrical foundation supporting the reactor
pressure vessel of the No. 1 unit of the crippled Fukushima Daiichi nuclear
power plant may be badly damaged across its entire circumference, its
operator said Tuesday. Some of the damage was revealed in videos taken
during a survey of the No. 1 unit’s containment vessel by operator Tokyo
Electric Power Company Holdings Inc., which said it would further analyze
the footage and assess the seismic resistance of the pedestal. The survey,
conducted from March 28 through March 31 using an underwater robot, found
the concrete wall missing in over half of the pedestal measuring 5 meters
in internal diameter, leaving the reinforcing bar exposed.
