I've been wondering about that too. Lately they indicate that the nitrogen injection is causing the pressure increase. I don't remember exactly when the nitrogen injection started but I seem to remember the pressure rising well before that.
EDIT: from the 4/7 IAEA report: "Instrumentation "B"...
Yes, they are radiator cooled. They mention "locomotive-sized" which I take it to mean very big. The larger generators we make (>3MW) typically use remote-mounted radiators unless they are CHP applications.
I wonder if we will ever know? I mean, doing any kind of forensic analysis is going to be pretty much impossible for any person on site due to radioactivity. Robots might be able to get in certain areas but may be hampered by debris. Getting large stuff off the top to examine the status of the...
Nice first post! You bring up some interesting observations. I hadn't even noticed those debris patterns until you brought them up. Hmmm...more to think about.
Looks like core pressure and temperature on #1 are creeping back up. Also noticed a new measurement for radiation.

No problem, please keep going. I didn't mean any offense. Glad to see you are thinking the fuel handling equipment went over to the north side as I suggested a while back.
I think that he is saying "stop it guys with all the speculation and photo examinations."
I have a headache from looking at all this stuff over the past week and am done squinting at photos until more info comes out. Until someone gets some eyes up close to this stuff (camera/robot eyes...
After looking a bit closer at the explosion photos I think the south side is illuminated, not in shadow. I don't know the exact time of the explosion but I am sure it is documented somewhere.
