SDF concludes dousing of No.4 reactor
Laaska News March 20,2011
Japan’s Self-Defense Force has concluded Sunday’s water-spraying operation to cool the storage pool of spent fuel in the Number 4 reactor at the quake-hit Fukushima Daiichi nuclear plant.
The operation was carried out in 2 parts, one in the morning and the other in the afternoon.
The second operation ended before 8PM.
The Defense Ministry says more than 100 tons of water has been discharged, and much of it reached inside the reactor building.
This is the first time since the initial quake hit on March 11th that the Number 4 reactor has been doused.
Cooling systems for the spent fuel rod pools at the Number 3 and number 4 reactors have been disabled since the quake, raising concerns over the leakage of radioactive materials.
Earlier, workers sprayed water for more than 13 hours into the Number 3 reactor, which is more seriously damaged.
