Charley, I'm confused as well, but that is the story in the Japan Times, Reactor 5 at Fukushima 1.

So- What do they mean by cold shutdown?
Did the quake/tsunami damage the rod containment so that water must constantly be added to keep the rods cool?
I dunno!

A report 04.04.11 said stability at 5-6 under threat. Listening to the youtube coverage of the broadcast of that date- youtube.com/watch?v=W7uGvW8xvY, they were worried about flooding at 5-6, but is is hard to understand the brief cuts by the spokesmen.
