Kyodo says pressure on #3, the reactor with plutonium, is growing. "Steps" are being taken to reduce that pressure. Meanwhile, authorities "shot" authorities into the spent-fuel pool of reactor #4:
1st water sprayed at Fukushima's No. 4 reactor
TOKYO, March 20, Kyodo
Japanese authorities shot water into a spent-fuel pool of the reactor No. 4 of the crippled Fukushima Daiichi nuclear power plant Sunday for the first time since the reactor's cooling system failed following last week's powerful earthquake.
The operator also stepped up efforts to reactivate the cooling system of the reactors No. 1 and 2 as power cables were connected to them, but the International Atomic Energy Agency chief indicated it was premature to have an optimistic view on the future of the troubled plant.
The Ground Self-Defense Force sprayed about 80 tons of water from a vehicle into the pool for nearly one hour until 9:30 a.m., according to the Defense Ministry.
