I think the lower left of the floorplan is the big garage door. So the access point would be East & South corner

@ peter, I"m trying to find some common rates for corrosion on piping, there will certainly be issues
by dean 1/19/2012 4:02:32 PM

@Peter yes 1st floor has containment doors. They are on the diagonal in that layout, lower left & upper right cuts into the containment circle that flare out on the outer edge represent the 2 containment air locks

hola' @ Pedro nice seeing you
by dean 1/19/2012 4:02:44 PM

@ Pedro, recovery is going well.. still in Physical Therapy and have started stationary bicycle training

you can see the access door on floor 1 on left side and see how far down it is into containment inside

@lilly, I must be underestimating the difficulty for getting a better video in there, I've done alot of these types of jobs over my career and I will say ours turned out a heck of alot better,,,

@dean I really wonder if they are using an Olympus scope camera that isn't rated for high radiation. I need to go back and look at your example cameras. Do they have scopes?
by lillymunster 1/19/2012 4:20:50 PM

yes @ lilly, the rad levels there should have been able to be tolerated if it indeed is a radiation hardened camera

at that level would they have been looking at the floor grating
by dean 1/19/2012 4:22:32 PM

head height level of the containment doorway is 12200 OP the bottom of the floor where the pedestal rests is 6180 OP
by lillymunster 1/19/2012 4:24:06 PM

6.02 meters to the floor from head height. About 20 feet
by lillymunster 1/19/2012 4:25:06 PM

they will definately need an interpreter for identifying what that camera is looking at, one time an engineer was looking at a scope camera and somehow forgot the camera was upside down... duh...they twist all around

i will return ..breakfast time..

@Peter wouldn't they have seen the water then? it would have been over the grate
by lillymunster 1/19/2012 4:38:00 PM


This image from the NHK broadcast if this is accurate shows the penetration about half way up the 1st floor height

@Peter The grate in pictures I think is the catwalk around at the level of the bottom of the containment airlocks
by lillymunster 1/19/2012 4:39:31 PM

6 meters to about head height, 5 meters would have covered the catwalk grate with water
by lillymunster 1/19/2012 4:39:58 PM

@Peter are my numbers matching yours? The difference I have on the elevation drawing shows a 6 meter difference between the floor bottom of containment and about head height of the air lock door level. So 5 meters of water would be about shin height on a person or maybe a foot over the bottom of the air lock door. Thus covering the cat walk grate

@Peter sensors
by lillymunster 1/19/2012 5:05:04 PM

Put together the details from discussions this morning along with diagrams and posted to the site. We can add to it or change if we find more

@Peter I wonder if the humidity is so high that water is collecting on the sensor giving a false reading.
by lillymunster 1/19/2012 5:19:48 PM

do we have any results from the endoscoping ?

TEPCO fails to clearly see inside damaged reactor
The operator of the crippled Fukushima Daiichi nuclear power plant has failed in an attempt to get clear images from inside damaged reactors using fiber-optic lines.
Tokyo Electric Power Company is trying to determine the state of nuclear fuel inside the plant's Number 1, 2 and 3 reactors. The fuel melted through the wall of each reactor's core units and fell to the bottom of their containment vessels after the March 11th 2011 earthquake and tsunami.
On Thursday, TEPCO inserted an optical fiber scope known as an endoscope through a hole into the containment vessel of the Number 2 reactor.
Photos taken by a camera attached to the endoscope show parts of walls and pipes inside the containment vessel. But the images were blurred, probably due to radiation and vapor from contaminated water, leaving details, including the surface of the contaminated water, unclear.
TEPCO says that the photos showed no serious damage or deformation to walls and pipes.
The utility also measured the temperature of the inside of the vessel for the first time since the disaster at 44.7 degrees Celsius. The figure almost matches the 42.6 degrees already shown by thermometers around the vessel.
It's the first time that TEPCO has examined the inside of the damaged reactors since the disaster. The company says it must understand the state of the reactors before it can complete its shutdown of the plant.
