I thought so as well.

I was under the impression that there was a large central pool in the reactor, where the rods were submerged in a circular organization. I don't see that in the image there, but I am notably uneducated about nuclear reactor design.

This is what I was working from:

You both very well could be right. This is the only diagram I've seen in related news articles, so I assumed it was right, but we all know how accurate news reports can be. rolleyes.gif

This is an image of the actual reactor #4 spent fuel pool.

Here's another image of #4. You can see the blowouts of the walls relative to the crane above the pool.

The more I look around, the more I'd like to claim accuracy for the image I originally linked to as a diagram of the reactor. Every single diagram I find related to the Fukushima I plant has the same basic design: Reactor in the middle, then a boxy spent fuel pool to an upper side of the reactor containment.

That picture cheats a lot.

It looks like the cover of the reactor pressure vessel.
There should be a steel cover (like a dome) on top of that.
This is during a yearly maintenance.

Go back to your post and click "Edit", it's still there; it simply seems like hotlinking that image wouldn't work for unknown reasons. I did not delete any links.

OK I understand. I was trying to embed a youtube video earlier and it was just appearing as a link. I couldn't get the video to play on the forum. I clicked the "embed" option under the youtube video and tried posting the code, php, I didn't know how to do like other are able to do, so I thought it was being blocked or deleted.

Just post the Youtube URL itself and it will auto-embed, no BBCode involved.

The latest update is:

Work halted at reactor 2 after 500 millisieverts detected.

http://enenews.com/news-advisory-repair-work-halted-at-reactor-no-2-after-500-millisieverts-detected

Tokyo says radiation in tap water above limit

http://www.chron.com/disp/story.mpl/ap/top/all/7486954.html



And it seems like this thread is dead.

So a good chunk of Tokyo is basically screwed if they drink the tap water.
That's 50 million thirsty people folks. 50 million. I have a bad feeling about this...

EDIT: Infants only, but I could foresee this becoming a serious problem if the levels rise
Nice to see that air radiation is now fine though
