Tokyo Electric Power Co. started the unprecedented and potentially risky measure of allowing water to flood the containment vessels of three troubled reactors at the Fukushima No. 1 nuclear power plant, company sources said.
It is the world's first attempt to saturate the entire containment vessel with water with the aim of cooling the pressure vessels inside the containment vessels and ultimately the reactor cores themselves.
So far, TEPCO has been injecting water into the pressure vessels at the No. 1 through No. 3 reactors. Under the new plan, TEPCO will allow the water to overflow from the pressure vessels through valves and ruptured pipes until the water fills the outer containment vessels.
According to TEPCO's road map, the water levels will reach the upper end of the fuel rods within three months.
The amount of water injected into the pressure vessels is about one ton larger per hour than the amount that evaporates due to the intense heat from the fuel rods.
The water level at the No. 1 reactor has been raised to about 6 meters above the bottom of the containment vessel. That level is 3 meters below the bottom of the pressure vessel.
But TEPCO has been unable to verify the water levels at the No. 2 and No. 3 reactors, and suspect that water is leaking from the damaged containment vessels.

- Per below line, will there be any rod there after three months of open air exposure?by Rob in SF 4/27/2011 3:39:36 AM

- Unit 3 Spent fuel pool water temperature.. condition : indicator failure. This does not even warrant a red box? it is blue like it is an OK thing.by Ralph Unger 4/27/2011 3:49:22 AM
@Ralph Unger They just put a sensor on the water crane there over the weekend....by Nancy 4/27/2011 3:50:56 AMTHIS JUST IN... finally got the latest 108mb T-Hawk 720x480 video uploaded.
by Rob in SF 4/27/2011 3:51:37 AM- Yep, my point is that having no data is a bad thing and it should be a red box kind of thing.by Ralph Unger 4/27/2011 3:52:40 AM
- @Rob Are the glitches my connection or the video?by Ralph Unger 4/27/2011 3:53:46 AM
- @Ralph Unger like the days of missing heat images on the days things were not good.by Nancy 4/27/2011 3:55:37 AM
- @Ralph Unger I get the glitches as well. Seem to be in the original MPEG but I did let YouTube process the source file, rather than mess with it myself in FCP.by Rob in SF 4/27/2011 3:56:14 AM
- No info there that I saw , other then it is a mess over there.by Ralph Unger 4/27/2011 3:56:55 AM
- @Ralph Unger What you want with the T-Hawk footage is the audio of the guy leaning over the shoulder of the operator telling him what to shoot...by Rob in SF 4/27/2011 4:01:16 AM
- I already have that, "Hey don't look at the SFP's or the reactor covers!"by Ralph Unger 4/27/2011 4:02:38 AM
Looked like rods still strewn about to me which reactor you think it was?by carabnr 4/27/2011 4:02:41 AM- The text description for the video on the TEPCO website is a big help:
Current situation between the turbine building and the reactor building of the unit 1, 2, 3, and 4
www.tepco.co.jpby Rob in SF 4/27/2011 4:04:52 AM - So why are they looking at this alley space?by Rob in SF 4/27/2011 4:05:33 AM
- I doubt that rods are strewn about, if in the reactor they would have a hard time leaving it and if in the SFP's they would be pushed down by the explosion, unless they went critical in a big way in which case they would be blow out of the SFP's.by Ralph Unger 4/27/2011 4:07:20 AM
- The radiation measurements I see do not support the idea that they went critical. www.tepco.co.jpby Ralph Unger 4/27/2011 4:08:28 AM
- At least not in a "big" way.by Ralph Unger 4/27/2011 4:09:31 AM
- I-131 reading do suggest that there is fission still going on somewhere at the plants.by Ralph Unger 4/27/2011 4:11:17 AM
- I think that at least 1 reactor or fuel pool is "chugging" That means that the fuel become critical and then creates enough heat to cause a disruption of the pile so it becomes sub-critical and it settles down and becomes critical again. The older data from the site showed a cycle like I am talking about. It is subtle in the current data. www.tepco.co.jpby Ralph Unger 4/27/2011 4:18:00 AM
- If your trenches are full and you have to keep pouring water into reactors, don't they flood, on purpose or not, anyway? Then say, " I meant to do that."by Scilla 4/27/2011 4:32:21 AM
@Scilla Wanna bet we will hear we had no choice but to release water into the ocean ?..by VeenOui 4/27/2011 4:34:29 AM- Catch 22. I gotta keep the fuel rods covered, I gotta not leak radioactive water into the sea. But any water I add to keep the fuel covered will leak into the sea. I am glad it is not my job.by Ralph Unger 4/27/2011 4:34:33 AM
- I get the impression they're visually inspecting the plumbing and HVAC in that latest T-Hawk video. Perhaps hoping to visually locate an elusive liquid leak? Or hedging their bets before transferring some highly radioactive water via the plumbing seen below?by Rob in SF 4/27/2011 4:35:34 AM

Pressure gauge for the Unit 1 Primary Containment Vessel.
From this we can glean? Anything? Why show it?by Rob in SF via Tepco.co.jp 4/27/2011 4:41:29 AM- I dunno, I think it means that there is some pressure so the vessel is not broken.by Ralph Unger 4/27/2011 4:42:48 AM
- Is zero ambient pressure or relative?by Ralph Unger 4/27/2011 4:43:41 AM
@Ralph Unger - you mean zero Absolute or zero Guage pressure right? Guage pressure 0 doesn't take atmosheric pressure into the equation, or 0=14.7Psiaby Lethbridgean 4/27/2011 4:46:47 AM- Yep That is what I meant and I was about to correct my post as it makes no sense.by Ralph Unger 4/27/2011 4:47:37 AM
- I meant relative or absolute.by Ralph Unger 4/27/2011 4:48:47 AM
- @Ralph Unger - my screen is tiny but on the face of the guage you should see the UNITS it reads in, if it ends with an A it is absolute if it ends in a G it is guage pressure.by Lethbridgean 4/27/2011 4:49:14 AM
- I can't tell on my screen, crappy netbook.by Lethbridgean 4/27/2011 4:49:45 AM
- Gonna pixelate it brb LOL.by Ralph Unger 4/27/2011 4:50:14 AM
- Even at major zoom, there is not enough pixels to read it.by Ralph Unger 4/27/2011 4:51:25 AM
- It was worth a shot anyway, they probably planned it that way, "see there IS some pressure"by Lethbridgean 4/27/2011 4:54:04 AM

- sorry if this was brought up earlier- but did anyone notice that many of the rad net monitors are out today?by inCalifornia 4/27/2011 5:01:58 AM
- Pls post the link.by Ralph Unger 4/27/2011 5:03:08 AM
- Info about the map. www3.nhk.or.jpby Scilla 4/27/2011 5:04:32 AM
