Folks, when someone references an older post by post number, how do I find that post? There must be a way to jump directly to it... if I enter a post number into the search box, I get no returns. Thanks in advance for your help!

Hi Razzz, This might help: NRC Boiling Water Reactor Systems Overview: http://www.nrc.gov/reading-rm/basic-ref/teachers/03.pdf

Astronuc, thank you for the reply. I confess I wasn't thinking about the velocities involved during normal ops (duh! facepalm). But on shut down, there must be a transition period between boiling with rods partially/mostly uncovered to +10m bathtub water. I'm sure that would be far far more...

Another question... Where is hydrazine stored (e.g., any stored in the reactor building where it might have been involved in the explosions)? How is it inserted into the coolant? Would it have been inserted after the scram in each unit (before the explosions)?

Hi Downwinder, Where did you find these facts please?

If that were the case, however, I would have thought they would have gotten the right ones brought in long before now, wouldn't they? I mean, even if it wouldn't have been in time to prevent the hydrogen explosions in the first 2 reactors, they would desperately have liked to have had power of...

Exactly - you and I are thinking on the exact same lines. But here's the thing, considering the location, and the fact that they are using CAMS, I would expect that area to always be quite toasty. You'd be getting shine from core itself, from 40 years of activation in the RV & D/W metals...

And here is probably the ignorance question of the decade... I had thought that BWR's ran with significant coolant cover over the assembly tops - but recently read that no harm would be expected in BWRs during normal operating conditions even, ran with as much as 1/3rd of the top of the rods...

I've been trying to understand a bit better what might have happened in the two or three hours post quake - and along those lines, to also understand better just how some of the emergency and residual heat removal systems would normally be expected to function (e.g., not specific to Fukushima's...

Hi folks, I'm new here, first post. I'm hoping that RealWing or other experts here might be able to help with a few questions. First, it seems that they've recovered CAMS readings on the drywell and suppression chamber. I'm interested in the significance, if any, but have no idea what...
