@Markfm So It can be washed off somewhat.

@fiona This will be a long term problem anyway you look at. Best senario is they stabilize everything and eventually clean the entire site.

@optim: I noticed from yesterday that there seem to be yellowish trees. Maybe it's only a colour effect from the sun. Or maybe they are "burning" from radiation. It would need cam shots from before the 11 to compare and make sure...

john.. my personal opinion on water level in vessels.. I think they knew then the didn't and as the situation worsened they didn't have any level indications..

@Optim: Someone explained here earlier that it took 3 weeks that the trees in Chernobyl turned brown, so it is too early to say something about that, I assume.
by Mina 3/27/2011 10:10:08 PM

@Dean Just watched a documentary on Chernobyl. Seems they were worried about the molten mass of fuel dripping down through the concrete into pools of water below left from the firefighting operations - speculating that it could set off a massive explosion (which is why they sent in firefighters to pump the water out). Is that situation different in Fukushima? Is physical contact between molten reactor fuel and water from the spraying operations a concern? (link to the documentary here: video.google.com )

wolf... there are safety relief valves on the steel reactor vessel system and the taurus.. I'd have been surprised if they went off with just the earth quake.. unless damage occured at that time..
by dean 3/27/2011 10:11:06 PM

@Mina : don't forget the salty water the tsunami brought. this can kill trees.
by Matsuoko 3/27/2011 10:11:20 PM

@Jo lindien: Worth doing the comparison. People interested in image comparison can analyse @mina: Third week since disaster has started. Let's see what happens in next 2-3 days

Somebody asked earlier about strontium and I think it possible that this Japan Today article has been edited because those commenting have obviously read something in the article about soil tests www.japantoday.com

@dean - the salt residue which has encrusted equipment , as I understand it , hinders cooling . My question is with so many unknown factors how deep could this crusting possibly be ?
by Salu 3/27/2011 10:11:45 PM

@nhk no idea how easy it is to get and apply large quantities of the solutions that the abstract says can be used to clean the concrete
by Markfm 3/27/2011 10:11:56 PM

i just wonder if the wind was blowing towards Tokyo what would be the reaction then
by fiona 3/27/2011 10:12:05 PM

@NHK Listener No, it is Spring, just like here. They are having unusually cold weather.
by Jim Carver 3/27/2011 10:12:44 PM

@NHK listener: OK, but aren't those trees some kind of fir or spruce ? Look like to me, but...
by Jo Lindien 3/27/2011 10:12:55 PM

@ALL I think this is new and relates bask to questions of strontium as a sign of vessel degradation/punture/leak. www3.nhk.or.jp
by marie rich 3/27/2011 10:12:57 PM

oh well, if the trees are still green then why are we still concerned? No danger at all, the plant is safe and healthy for humans..
by Caorso 3/27/2011 10:12:57 PM

If the wind is blowing towards Tokyo, TEPCO will issue a statement saying it's blowing the opposite direction.
by Miles 3/27/2011 10:13:02 PM

jay... it can be the same thing at these plants in that the molten core burns through the bottom of the vessel.. (there was a web link Iposted explaining that) .. which would drop into the supression pool and have that sort of reaction
by dean 3/27/2011 10:13:12 PM

@dean, Thanks but in that case where could this reported steam have vented from ?
by WolfDK 3/27/2011 10:13:30 PM

There is a clear black smoke just left of the first Also from white tower from right. It's clearly visible in the web-cam. www.tepco.co.jp We have seen this before so we should not be alarmed..NO?
by Optim edited by George Gibb 3/27/2011 10:14:28 PM

salu.. try an experiment on the stove.. put about 2 cups of salt in a sauce pan of water and boil it off... JUST KIDDING.. there would be alot of build up over this time by now... inhibiting the heat transfer when clean water is introduces
by dean 3/27/2011 10:15:09 PM

@Dean In the documentary, they speculated a 3.5 megaton explosion would have been set off that would have razed Minsk (~350km away). Has that theory been since refuted (I think the documentary came out a few years ago).
by jay77 3/27/2011 10:15:20 PM

@dean Thanks for offering to relay our questions. Do you have any info on the prospects of liquid metal cooling?
by es 3/27/2011 10:16:04 PM

@Jo Lindien: Please remember about the effect salt could have had on the trees. Let's not speculate.
by Bart 3/27/2011 10:16:10 PM

jay.. I'm not sure about that.. there are so many differnces in these reactor..
by dean 3/27/2011 10:16:13 PM

OPINION: I don't have a date stamp for this photo, however I am relatively certain it was taken before 3/11/11. The trees appear substantially greener in this photo than they do on the recent TEMPCO webcam shots. Just my opinion www.ens-newswire.com
by Tenzing via Ens-newswire 3/27/2011 10:16:20 PM

@Bart: you're right. Salted stream may have fallen on the trees...
by Jo Lindien 3/27/2011 10:17:43 PM

I think one very important thing.. the fuel is still contained in the vessels for 1, 2 & 3 and in the canal.. it's still 40 feet deep and there is alot of concrete shielding.. the worst rad levels are up in the air above the reactors.. and that is the safest place for the fuel debris (what every shape they are in) to be
by dean 3/27/2011 10:17:46 PM

@Tenzing Also consider that the height of land from that angle rules out salt damage.
by George Gibb 3/27/2011 10:17:46 PM

@Tenzing: Compare this with current tepco image. The 3 towers are colored differently... strange R u sure this is Daiichi?
by Optim 3/27/2011 10:17:59 PM

@bart i live on the sea shore and i don't think salt does that to trees in such a short space of time - but over a longer period of time it fades all the red cars!
by fiona 3/27/2011 10:18:46 PM

those stacks you see in the picture are usually depended upon to take the air off the facility up the stack and disperse it in the air up at that leve.. those stacks failed which left all the activity down in the faility.. I hope they don't start them ..
