From what I have read, the #1 reactor was going to be decommissioned this month anyways (been in operation since the early 70s), but I doubt they wanted the extra cleanup this tsunami dealt them.
Apparently, there's fears in the government there that there's is, or was, a meltdown of the reactor cores of units 1 and 3, but because the reactors aren't safe yet, they haven't gotten close enough to them to see.
There's also issues with Fukushima Daini (II) with the cooling pumps in units 1, 2 and 4 stopping. There doesn't appear to be any danger from there that I have heard of. Tokai Nuclear Power Plant also had coolant problems in unit #2, with a pump having stopped working, but another pump was working; however 2 of the 3 diesel generators are out of order as of right now. Onagawa NPP had a fire in the turbine section, but doesn't seem to have damaged the reactors there; then there was an elevated level of radiation there, but they think that came from Fukushima Daiichi and there was no issue with Onagawa. It seems like there are several people who have been affected by radiation from Fukushima Daiichi, but I haven't seen to what extent.
Right now, the Japanese are doing everything they can to prevent the worst-case scenarios with their power plants and, so far, they are succeeding. The only good thing that I can think of that will come out of this is better understanding of how to respond to nuclear emergencies at power plants.

Yeah, a Hydrogen explosion blowing the roof off the containment building during a coolant loss is bad, but if (as stated) the containment vessel is intact, it's a minor annoyance compared to the earthquake and tsunami.
They're flooding the core with seawater and boric acid, then they will fill the entire containment building to keep it cool. Not good for the reactor, but apparently the core is already ruined, so it ain't gonna make things much worse.Duncan Edwards wrote:Packerton wrote:http://img847.imageshack.us/img847/438/fallout.jpg
This image is all over the net, hope its not true.
I don't see how it could be. The figures they are quoting exceed anything ever delivered in Pacific nuclear bomb tests. That would also be from an uncontained total meltdown which this is very unlikely to become. Chernobyl was not a light water reactor nor was it housed in a containment building. I suspect strongly this is a piece of scary artwork.
EDIT - The logo in that map is from a private Australian company that I suspect has nothing to do with it. They not only make no mention of it on their website I can't imagine how a private company that appears to specialize in mostly industrial situations would have access to such detailed data.
