The steam observed rising above No.3 for hours is radioactive. It is now presumed that the containment vessel has cracked. SDF had prepared to drop water from helicopter, but could not do so safely.

“Tests revealed traces of radiation in tap water in Fukushima city, 80 kilometers (50 miles) from the Daiichi nuclear plant, the local government said Wednesday. The Fukushima prefecture’s nuclear department said amounts of radioactive cesium and iodine that are not harmful to the human body were found in water samples taken at 8 a.m. Wednesday (7 p.m. ET Tuesday)…
Government officials said the traces found are connected with the nuclear plant. A measurement of the tap water supply taken later in the day found no traces of iodine or cesium.” -cnn live blog

conditions at the Daiichi plant have continued to deteriorate. The greatest concern at this time is over exposed spent fuel rods at the no. 3 and 4 reactors. As of now, radiation has prohibited workers from adding water to the pools…
A road has been built to allow a water cannon truck to approach what remains of the structures. Police hope to shoot water through the holes in a last ditch effort to prevent the rods from reaching recriticality. The chance that heat being generated from these hundreds of rods (many reactors worth) will lead to nuclear reactions is very real.

SDF helicopter has dropped some water on reactor no. 3.
Radiation readings after the water-drop remain the same as before.

Tired. But staying up to watch what happens with the trucks. The Defense Secretary says this is the last effort for his forces – that after today, radiation levels in the area will be too high for them to participate. However…it is possible that the President will order their return, under law that says when other lives are at risk, occupational limits do not hold.

“[7:37 a.m. ET Thursday, 8:37 p.m. Thursday in Tokyo] An operation to spray water on the No. 3 nuclear reactor at the Fukushima Daiichi nuclear plant has ended after 40 minutes, Japan’s Defense Ministry says. Five fire trucks took turns spraying water for two minutes each, officials said, and there was no further spraying planned.” -cnn live blog
TEPCO reports that radiation levels rose after the operation (exact rates were not given.)
“The level around the plant’s administration building rose to 4,000 microsievert per hour from 3,700 after the trucks joined an unprecedented attempt to cool down the reactor’s apparently overheating fuel pool, after SDF helicopters dropped tons of water earlier in the day.” -kyodo news
The Defense Ministry says that choppers and trucks will be used again on Friday.
