Still think there has to be some plants, fungi, bacteria that would bind this stuff up in some way and put it to good use or no use. Maybe the GMO people can work on that one? 



Emerson, thank you for all your input. You still have me thinking of a way to power my house with pecans.

Mekka Pakanohida, you made me hungry for miso soup.



Yeah I am making a batch of it right now. (The miso)

I was over at PRI forums & there was something about bacteria working with Uranium & links.

Aganpipe, doesn't the type of fuel rod also matter?  Some are better than others, etc.  Also, I just read a report that PG&E nuclear facility near Diablo Canyon, Cali hasn't had a earthquake response in well, nearly forever.  This facility is near San Francisco & as a former resident that lived through several earthquakes there, well, I'm rather pissed at CA, and happy I am in Oregon.

As for powering your house, have you thought of a biochar burner?  Some people use them to fuel their homesteads while making biochar for use on said homestead.














Lastly, getting back on topic.  Did you know Dusty that nearly everyone in New Jersey lives within 10 miles of a Superfund waste site?  The Garden State should be renamed to the Glowing State.

thanks for the info Aganippe and confirmation Emerson and the heads up Mekka.

Mekka, is PRI forums Permies RI?
saw some stuff on permies after doing a quick search that said search/google "pearls before slime".

on the biochar burner, will have to research that some more. was looking at making some charcoal when a big tree fell down in the back yard. Didn't find an efficient model then, but sounds like there are some. That tree's going to get hugeled in the near future, as it's gone to the fungi masters now.

Here's a link to an AlterNet update summarizing stories from various sources -

http://www.alternet.org/rss/1/530223/nuclear_crisis_--_report%3A_impossible_to_predict_fallout_in_us%3B_japanese_defense_forces_begin_water_drops?akid=6674.154357.tsiC5D&rd=1&t=5

Keep in mind that AlterNet definitely has a sky-is-falling mindset, but you can check out the various sources yourself.

My father sent me the alternet story, I was rather unconvinced by it.

Honestly I do not know enough about the metallurgy of fission fuels to make a sensible comment, it does seem to be a highly specialised field.
That said I will make an attempt. Understand that I may be well wrong here. Also understand that this will be a somewhat disorganised answer. I shouldn't have to tell you not to try this at home.
In terms of the fissionable isotopes, my understanding is almost all use some form of uranium dioxide, either palletised, or sintered in place with a bunch of filler. This filler would be mostly for structural support, and would be chosen for a minimal influence on neutron velocity and path.
Different types of fuel rod, would be talking more about the different fillers being used, each with different thermal responses. ( aka, they can take different amounts of overheating before softening or melting).
I have read of sequences where control rod channels become blocked, either by distorted fuel rods, or by the control rod itself distorting and jamming the channel. This is more of the problem with solid moderator reactors than liquid moderator reactors, although it is still possible.
This failure mode is only relevant ( towards runaway) whilst the control rods are withdrawn, If it occurs whilst the control rods are fully inserted ( as in a SCRAM), the effect is merely to reduce the upper capacity limit of that plant, or to prevent restart.
That is the limit of what I can think of, in terms of different fuel rod 'types'.
Remember in the class of reactors that we are talking about, at least some active cooling *must* be used, even with the core in full shut down.

The *entire* time that there is the potential for a high energy decay to occur within the fuel in the reactor core, the reactor core is capable of creating heat. Over time, that potential to create heat is reduced, as the fuel mostly changes states to a more stable form ( more stable in terms of isotopes. the less potential for high energy emissions, the more stable). This is why in usual operation they change out the fuel rods from time to time, in order to hold the core at a given level of potential energy.

Also remember the entire job of a nuclear reactor is to turn water into high pressure ( and thus high temperature) steam. That is what it is designed to do. The rest of the power plant is *exactly* the same as you would find in a coal plant, a natural gas plant or a geothermal plant.

In short, talk of hem using " a different type of fuel rod", is IMO, a red herring. It might be true, but it is irrelevant. Understand that the press is not going to report on this dispassionately. This is a dangerous black magic to a majority of people's minds, and they will play on that discomfort.

They are not going to admit that ultimately what they are talking about is just another kind of boiler, and that overpressure in any other kind of boiler is harmful too, as is running a boiler dry.

Ignore most of the voodoo sky is falling crap. Yes this can emit substances that are undetectable without specialised equipment and can kill you. So can granite.

These reactors run with UZrH rods rather than UO[sub]2[/sub] rods, and that is very relevant because the UZrH becomes less reactive as the temperature rises, and provides less resistance to heat transfer, in turn this means a lower likelihood of meltdown. A draw back is that the Zr oxidizes at extremely high temperatures in the presence of water, releasing H[sub]2[/sub] gas. The vented steam contained this hydrogen and that is what caused the explosions in the containment buildings, though it is better to have that energy released outside of the containment vessel than in it It is not good to have an explosion.

Why hasn't this been moved to the Meaningless Drivel forum yet?

I stand corrected,  thanks  Emerson. And that is interesting.

I make most of my biochar the old fashioned way, I make a fire because at this moment I don't have the resources to make a biochar facility or good burner,  but it is on the list of things to be done within 5 years for this property as I have been doing experiments with it.

I really wish one of those biochar facilities would open near NYC even though I no longer live out East.  I remember the last time I was there that people are now living on top of old landfills both in NY & New Jersey.  I can't help but think of the toxins building open under those conditions...  ..which does give me pause about a place I knew on the isle of Oah'u.  It seems that this company behind my University was allowed to strip mine the island in to make dolomite which gets shipped to the mainland.  The strip mine is then filled with garbage from the island, which, in the past have started underground fires.

Lot of craziness out there making it unsafe for living, as the original post was eluding to.

Why I need to look for more like minded people within walking or biking distance to do some experiments together.

There is a neighborhood in wilmington north carolina called Land Fall. I hear the only had to change on letter on the map when they renamed it from Land Fill. They occasionally have hurricanes make Land Fall there, so both names are appropriate.

Sound like a diagnosable psychological disorder.
