By now you all know the story. The video has to be seen to be believed. Sendai looks like a G--d---- nuclear bomb hit it -- unbelievable devastation. Our family and friends in Japan are all accounted for and safe, thank God, but as a survivor of a major earthquake myself (Northridge '94, 6.6) I can guarantee you they are scared. (Our Yuki is here in the USA, in Orlando, so she's safe.)
For continuous live steaming video, open NHK in a window and let it run. The shibō/fumei counter inset into the video image is bone-chilling, like Hell's scoreboard. As you monitor, keep an ear open for the phrase genshiryoko hatsuden-sho [原子力発電所, "nuclear power plant"]. They lost coolant pressure at the big plant near Sendai today. I'm a former nuclear power worker, and let me tell you that's a sphincter-clenchingly scary situation. For a reactor that big (1100 MW) to lose all coolant pressure to the core is a nightmare scenario. Fortunately it's an BWR (boiling water) type reactor, so even if the core runs dry it can't melt down Chernobyl-style; without water in the core to thermalize (slow down) the neutron flux from the rods, the reaction stops (steam being more or less neutron-transparent, stopping criticality in the core).
Unfortunately, if coolant flow stops, whatever is left in the reactor core is going to flash to hot steam at high pressure (about 500°F @ 1100 PSI) and it's gotta go somewhere. I guarantee you that they will vent the core to secondary containment (the reactor building and control areas, basically) to save the core and pipes from rupturing, and that building isn't airtight; some radioactive steam will get out (if it hasn't already). Result: the control room and everybody and everything in it are going to end up being contaminated.
And they are going to have to dump the steam in the containment building sooner or later Radioactive steam on top of the Hiroshima-level destruction... not pretty.
Give money to relief organizations if you can. Otherwise, please pray for the folks in Japan who are hurting tonight. There's really nothing else to do.

Pikadon Redux?

"I had seen enough "Blade Runner/The Day After" movies that I had half expected to encounter mutants walking around town or troglodytes emerging from the sewers.
Meanwhile, near Ground Zero just below the precise spot where the Nagasaki bomb had detonated, I saw several American fast-food restaurants including the smiling face of Colonel Sanders."
Manga in Japan: diminished hopes
Once again, Matt Alt has his eyes on the road ahead and gives us a heads-up. More commentary from Carl, Uncle Tim, and our very own B-Chan.
A good read, however depressing.
