I've been thinking of buying tuna again since things seem to be relatively safe in that regard (of course, there are other things besides radiation to think about). I'll be getting more American Tuna - they fish up the west coast, around Alaska-ish, where the tuna are hanging out when they're younger.<br /><br />I have quite a bit of family in CA but nothing I can do about that.<br /><br />shadowfoothttps://www.blogger.com/profile/16024745044730301470noreply@blogger.comtag:blogger.com,1999:blog-2703718837080088488.post-52669118261351453502016-04-16T21:56:50.851-05:002016-04-16T21:56:50.851-05:00If there is elevation change in the area in questi...If there is elevation change in the area in question, and a flow gradient, then yes, the freeze method would be much more likely to fail for the reasons you mention.

A...Aimee - I am a believer in physics and geology. And statistics. Sea level rise is most certainly going to happen, though the immediate effect on house prices is not clear to me- real estate cons are a huge source of wealth, predictably. In terms of radioactivity from Fukushima affecting your fish, and then your health- probabilities there are very tiny; the fact that we can detect it does not mean it will have measurable health ramifications. I would not live in California, for anything. Visit, yes I do, small windows of time are not much problem. Long windows- bad things. The NW - I think is a bit less risky at the moment; but- that's a guess; human ability to truly gauge earthquake hazard is very poor.<br /><br />Steve- yes, freezing soil for construction is an understood technique - but it's entirely different from trying to immobilize an aquifer. That's never been attempted, I think. In the construction practices, water is allowed to move through the set up, specifically so pressure will NOT build.<br /><br /> Water moving through soil/rock microstructure is as slippery as hydrogen molecules to try to contain. And water pressure is an exceptionally powerful force, since water is incompressible; force is transmitted completely. So- envision - water is freezing in the soil, restricting established flow paths. Pressure builds. Water will find (is finding now) paths not yet blocked; and start to flow faster there. More pressure- faster flow, greater force. Various kinds of erosion, cutting, changes in solubility of rock/soil minerals will happen, and the existing pathways will grow- increasing flow. High flow- harder to freeze, since new heat is constantly supplied- Now; put an entire aquifer, rain on the mountains, in back of that. It will go through; or around, and begin physical erosion and/or soil liquefaction- <br /><br />That's only one set of reasons. Basically there are no "possible" or "probable" effects that might operate to make it work- and all known ones will operate to make it increasingly improbable, and will likely join forces down the unknown road to make it really, really improbable. My prediction - it won't work. Resources and time will be entirely wasted, and should be spent on finding some pathway with a reasonable chance of success.Greenpahttps://www.blogger.com/profile/17224906349154302210noreply@blogger.comtag:blogger.com,1999:blog-2703718837080088488.post-45623072002120511762016-04-01T22:13:20.150-05:002016-04-01T22:13:20.150-05:00Aw, come on, tell us why you don't think the i...Aw, come on, tell us why you don't think the ice walls will work. Using freezing to isolate foundation work from groundwater or high water tables is a well known construction technique. I know nothing of the geology and groundwater situation there, but if done as per successful past experience, why wouldn't it work?Steve Carrowhttps://www.blogger.com/profile/11706114439618856525noreply@blogger.comtag:blogger.com,1999:blog-2703718837080088488.post-18321786401445923752016-04-01T16:25:11.160-05:002016-04-01T16:25:11.160-05:00Would you be worried if you lived on the northwest...Would you be worried if you lived on the northwest coast of the US?

In this case- it turned out the water they were pumping up - was already too radioactive to release without treatment- and local fishermen were watching it all very closely. And a bunch of the contamination is tritium - for which no one on this planet has found any economical ways to remove it from water like this. No filters or other processes can do it. So they wound up with more water they had to store; not less, and more that was ultimately too contaminated even by their own relaxed standards to dump in the ocean... so- the entire project just quietly disappeared from public view or discussion.<br /><br />They've built physical walls- that made it worse, and a couple other things- all pretty much on the "we have to look like we're doing something" level. The plain fact is, the technologies to deal effectively with a melted reactor core- do not exist, anywhere. But good Public Relations efforts - can keep the panic down a bit.Greenpahttps://www.blogger.com/profile/17224906349154302210noreply@blogger.comtag:blogger.com,1999:blog-2703718837080088488.post-32053808594587833552016-03-31T12:37:52.459-05:002016-03-31T12:37:52.459-05:00I realize there must be quite a bit of water flowi...I realize there must be quite a bit of water flowing into the area, but if they're going to spend lots of money wouldn't it make more sense to figure out a way to divert the underground river? Like maybe dig a huge trench (new riverbed, really) that goes in a different direction, then connect it to the river? It would be a ridiculously huge project but building those freezing units must have been a huge project as well.shadowfoothttps://www.blogger.com/profile/16024745044730301470noreply@blogger.comtag:blogger.com,1999:blog-2703718837080088488.post-37256774779244835412016-03-31T06:36:36.569-05:002016-03-31T06:36:36.569-05:00I dot have a degree in chemistry or physics.
