by Nancy via Houseoffoust 4/18/2011 2:00:19 PM- @Markfm @LM Thanks for the link to 5meters. I find it hard to believe it is true, but Kyodo cites. NISA. Anyone here believe a building there would hold 5 meters of water column?by RBean 4/18/2011 2:00:39 PM
now look at these other heat images on 4. this is the 20th www.houseoffoust.com
by Nancy via Houseoffoust 4/18/2011 2:00:59 PM- @RBean : no.by Edano 4/18/2011 2:01:05 PM

Can metal become irradiated enough to emit? If the water in the well has evaporated, could the metal itself give off heat? Chernobyl has a truck/car/cement mixer graveyard. The pattern could be caused by the beams partially blocking?by marie rich 4/18/2011 2:01:49 PM

by Nancy via Houseoffoust 4/18/2011 2:02:27 PM- ahh: look. the symmettrical "X" structure of the hotspot can be caused by the steel pattern of the roof !!!by Edano 4/18/2011 2:02:54 PM
Then here is today's www.houseoffoust.com
by Nancy via Houseoffoust 4/18/2011 2:03:09 PM- @Edano that's what I just saidby marie rich 4/18/2011 2:03:18 PM
- @Edano yes. we thought there were rows of heat on those older images. It is the roof trussing going over a larger spot and making stripes in it.by Nancy 4/18/2011 2:03:36 PM
@RBean If it's an area below ground level..perhaps.by LM 4/18/2011 2:03:53 PM- Can it be the well itself? Now the water has probably all evaporated. The metal could be highly irradiated.by marie rich 4/18/2011 2:05:06 PM
from my experience on the reactor I worked on ... even with all the fuel out of the reactor when we shutdown to do tank work.. there were still so many thermals coming off the irradiated components that we had to maintain some minor flow to help out... so, it's possible that in a much larger reactor with shroud still in to have thermals..by dean 4/18/2011 2:05:29 PM
I'm thinking LM may have it right, though as JO correctly noted those containments are supposed to be pretty much air/water tight (just that I expect cracking by now)by Markfm 4/18/2011 2:05:51 PM- It looks like todays is just on the edge of the well but it is so round and intense. The new thing I am using to try to pinpoint the well is the crane since the crane has to straddle the well and the sfp. That makes the well just barely over the mid line long ways so a small part of the circle may be over the long midline.by Nancy 4/18/2011 2:06:01 PM
- Hmm, what marie and dean are saying could be the thing. if the well structures themselves can be "radioactive" and give off heat. That could explain maybe. Still a bit puzzled by the two heat areas. I really need more images of the work floor of #4 before the quake. It could give some definitive answers.by Nancy 4/18/2011 2:07:30 PM
- At @Nancy I've thought that the bldgs. keep looking more and more deteriorated (aftershocks? water weight?) Maybe the 'movement' is beams and wall pieces shiftingby marie rich 4/18/2011 2:07:36 PM
- At Chernobyl they have a huge car/fire truck/cement mixer/ chopper graveyard of irradiated metalby marie rich 4/18/2011 2:10:13 PM
- @marie rich the newest images of 4 don't show any changes that I found. I was going through them yesterday and marking floor lines, placements of known items and wall structures. Nothing I found had moved and the floor on 4 looks the same. Look at those old heat images, everything is off to the seaside of the mid line of the building. Now today the hot spot on the mid line.by Nancy 4/18/2011 2:10:33 PM
- From the NRC "The radioactivity can range from just above background levels found in nature to very highly radioactive in certain cases such as parts from inside the reactor vessel in a nuclear power plant. " You do get some transference, contamination.by Markfm 4/18/2011 2:10:37 PM
- @marie rich I remember seeing those vehicle graveyards. But does that kind of thing radiate heat?by Nancy 4/18/2011 2:10:58 PM
- @Markfm So if this is the well and it is heating up what changed today vs. weeks ago?by Nancy 4/18/2011 2:11:29 PM
@Nancy - The breakdown of any isotope creates heat. The shorter the half-life, the higher the heat.by Hank Scorpio 4/18/2011 2:12:06 PM- They are getting the water into the spf instead of everywhere?by marie rich 4/18/2011 2:12:08 PM
- If I'm not mistaken. :)by Hank Scorpio 4/18/2011 2:12:12 PM
- This is the first mid line hot spot that hot. A few faint heat spots on the midline earlier but not this concentrated and hot. Was there water in the well and now there is not? Have they been draining 4?by Nancy 4/18/2011 2:12:14 PM
- It would evaporate- both naturally over time and by heatby marie rich 4/18/2011 2:12:48 PM
@Nancy Need to find out if possible, what they were doing before the accident. But nobody seems to know that.by Jim Carver 4/18/2011 2:13:01 PM- @Hank Scorpio there had been some assumption that the scattered rod materials TEPCO talked about could be on 4's deck.by Nancy 4/18/2011 2:13:07 PM
- Hot spots showing now, but not earlier? Crack in the RPV itself from one of the earthquakes, or else in pipes/assemblies at the bottom of it, which let out the water that had previously masked the heat (by spreading it out -- water has very high heat capacity)by Markfm 4/18/2011 2:13:31 PM
- @Jim Carver The TEPCO line is "routine maintenance"by Nancy 4/18/2011 2:13:35 PM
@RBean: no problem to flood 5 meters of water in the building; remember the building goes 10 or 15 meters underground...by Jocelyn Mayer 4/18/2011 2:13:42 PM- Of course no word what that entails.by Nancy 4/18/2011 2:13:43 PM
- (I'd expect penetrations at the bottom failing before the main RPV, certainly)by Markfm 4/18/2011 2:14:21 PM
- @Markfm Maybe that is where the water they cited is in 4's building came from?by Nancy 4/18/2011 2:14:27 PM
- @Markfm nothing in the RPV so something would have to break to make it leak. A pipe coming loose?by Nancy 4/18/2011 2:15:00 PM
- What day was the last big-ish quake. Wasn't there a 6 there recently?by Nancy 4/18/2011 2:15:23 PM
- Pretty sure they have poured a couple million tons in, easily, based on the numerous reports of anywhere from 100 - 170 tons going in on a given day. The water had to go somewhere.by Markfm 4/18/2011 2:15:27 PM
- The well is kept full of water whether operational or outage. At first, they used shotgun approach and some water probably splashed into well, too. But when they got the big booms, the water was more directed. Water evaporates no matter what, but esp. with heat. So maybe it just dried up in the well?by marie rich 4/18/2011 2:15:48 PM
- @Markfm On 4 they have been alternating between spraying the pool and broadcast spraying across the roof line onto the deck.by Nancy 4/18/2011 2:16:08 PM
- @Markfm @Nancy Because most of it didn't go where they wanted anyway.by Jim Carver 4/18/2011 2:16:26 PM
- That was what was so ineffecient about that. Try standing 10 ft. away and try filling a mason jar with a garden sprayer.by Jim Carver 4/18/2011 2:18:07 PM
