The meltdown news from Japan continues to raise questions and concerns. Fresh on the heels of the revelation that Fukushima Daiichi unit 4 is sinking into the ground comes word that hydrogen has been building up in unit 1-- so much so that Tokyo Electric is pumping nitrogen gas in to prevent an explosion. That place is going to be a continuing danger to the world, and especially to us downwind and downstream in the Pacific Northwest, for decades to come. "Cold shutdown," my eye.
