The successful removal of a beam dropped into a spent fuel pool, the first Tokyo Electric Power Co. settlement related to the death of an evacuee and a higher seawall at the Hamaoka nuclear plant highlighted the last week’s news from Japan.
Developments related to the Fukushima Daiichi power plant severely damaged following last year’s earthquake and tsunami include:
Beam Removed from Unit 3 SFP
While clearing debris from around the unit 3 spent fuel pool on Sept. 22, a piece of remotely operated equipment dropped a steel beam into the water. TEPCO workers retrieved it Thursday, according to a release, after practice runs using a mockup of the beam and the SFP. Before the beam was lifted from the pool and set on the ground next to the reactor building, crews also lowered a system of rods and chains into the SFP to protect its liner during the procedure. A water purification system was also installed that TEPCO said doubled visibility in the pool to 5 meters. No damage to the liner or changes in plant conditions were detected after the beam was removed.
