Don't depend on "brian_g stumble butt dumpster diver" to do anything scientific. Even it agrees to this contention.
However, "brian_g stumble butt dumpster diver" takes on himself & has no power to ask questions, receive answers, or use such knowledge for societal advancement. Never did it obtain science or mathematics degrees. Never did it obtain upper class science, chemistry, astronomy, physics, algebra or pre-calc for its poorly earned hi skule DEE-plooomaa.'brian_g stumble butt dumpster diver' has made errors of 1 million TIMES, 1000 TIMES, 3000 TIMES, & 73 million TIMES.
What "brian_g stumble butt dumpster diver" does ask, is what has been known for decades. If its sins weren't worse than its arrogance, "brian_g stumble butt dumpster diver" is silliness personified & it has no intelligence in any science or mathematics. However, beyond silliness, "brian_g stumble butt dumpster diver" is a slimy steenking filthy vile reprobate rooting(& rotting) racist pukey proud pig AND 4-time alleged AND 4-time proud threatener.
More and more that’s all the "pinheadlitesout" have more and more diarrheas.

I remember your 4-time alleged threats. Then, there were the 4 proud threats you made, that you gladly admitted to, with no encouragement from me. Then there was your avatar that showed your deep racism & anti-patriotic stance. Yeah, the whole re-pubic-lick-un party liked thet 'un. Of course, the re-pubic-lick-un party showed their racism & anti-patriotic stance.

Yes, I see why you hide out in Germany. The U.S. just don't got no attraction for you.......

<quoted text>SoE,
LWR plants and LFTR plants are totally different, so converting the first to the second would be impractical. However, since LFTRs have a much smaller footprint than a typical LWR, it should not be difficult to install one on current LWR reservations and at least make use of the grid infrastructure.
Weapons grade materials come from totally separate facilities. It is not practical to make weapons using power reactor Spent Nuclear Fuel. It is even less practical to use material from a LFTR NPP.
I was trying to consolidate some of the functions.
I new there were going to be problems from the beginning and at that time had an intutuive understanding that the problems would
be bad considering health risk...(monitoring Hanford)etc.
Just in terms of the economics of decommissioning and construction of new facilities discounting waste disposal and accompaning health risk this is beginning to appear a first magnitude disaster..
The point that were at now given the fact that the clean-up of Hanford by Bechtel is going so poorly (design on the fly)is going to surpass the national debt..
There are three ways decommission can be accomplished and plants appear to not have the money set aside in some cases....This just get worse and worse....
We will continue to construct weapons fuel regardless of any apposing view.
It just goes on and on...

Good to see that you can set aside your Son of Entertainment attitude. Excellent post but, NRC requires plant owners to set aside money when the plant is still operating to pay for the future shutdown costs. So where is the money? See why Wind Mills Rule.

So, where is the money ?
I,m not sure i'm following you here..
NRC requiring set-a-side should mean the owner investors have it..

Please don't confuse Hanford, a nuclear weapons site, with typical nuclear power plant sites. They are worlds apart. First thing is that Hanford used the PUREX method to extract ultra-pure Plutonium for bombs. PUREX results in a LOT of nasty waste products.
Here in the US, NPPs are required to set aside a certain percentage of their income for decommissioning costs. The Trojan NPP that WAS downriver from Hanford is gone now. Their decommissioning seems to have gone just fine.
What NPPs have is a political issue. They have been paying the FedGov a fee to be used to handle the Spent Nuclear Fuel in a consolidated manner but the FedGov has been dithering for decades.

What COULD be done is to use a variation of something called pyro-processing to segregate the SNF into three pots, the big one being the UNspent Uranium. That can be either vitrified and returned to the earth or reprocessed for LWR fuel. This represents about 95%-97% of the total.

The second pot is Fission Products (~2%-3%). Those can be dry casked for medium term storage (~500 years). Many of the FPs are stable after 10 years and can, if economical, be separated further; reducing the amount that needs to be stored. Some of the radioactive FPs are valuable because of their special radioactive properties. These can also be further separated and thus reduce the storage needed.

The third pot (~1%-2%) is the stuff that Yucca Mountain was intended for. It is comprised of the stuff bred from some of the U238 in the original fuel. These are the "transuranics" including Neptunium, Plutonium, Americium, and Curium. These are nasty and have fairly long half-lives. These would need to be stored or 10s or 100s of thousands of years. However, these can also be put into Liquid Fluoride Thorium Recyclers and burned up.

In my observations of radioactive elements and their existence dates back to when we first entered into this realm of energy. Various experiments conducted openly and secretly exposed us to radioactive elements. One example of how we can observe the spread rate and separate it from natural radioactive elements. Let us take Strontium 90 which has ½ life span of 300 years. This was produced with the testing of one particular bomb we will call it the U-Bomb. Only 15 were tested. Strontium 90 was one of its radioactive elements. Deductive reasoning gives us the realization that all the Strontium 90 in our present day atmosphere was man-made. Strontium 90 is of the calcium class. Now consider that at present not one living organism does not contain a portion of this element. I will not go into the various medical factors that this could be affecting other than note the rise in bone marrow cancer from say 60 years ago. Now consider radioactive elements with ½ life times of 20,000 years and their dispersals. Keep in mind the affects of radioactive accumulation that will not be flushed out of living organisms. Dispersal of radioactive elements will be global in virtually all additional contributions. Accident or not.
KitemanSA brings forth one small method for treating one particular radioactive element. There are also chemical processes but neither can address the more ardent radioactive elements. Radioactive desegregation from say U-235 to Plutonium and its various purities are constantly affected only by time.{Note when earth is closest to the sun radioactive elements slow in their radioactivity and increase at a greater distance from the sun. Einstein again proven correct.}
This leaves me with one bottom-line answerer to radioactive elements production, is presently, needs to be extremely limited. For medical and R&D research, BUT not as a source of energy generation. We have not matured our responsibilities to our technology presently. Advancement on Alternative Green Energies would be a prudent course. Future generations, requires us to reign in our intelligence to keep pace with our abilities to contain the responsibilities of wisdom.

All really sensible men agree that the prudent course is to be neither bigoted in our attachment to the old nor rash and unpractical in keeping an open mind for the new, but to make the best of both dispensations.

Sorry, Sr90 half life is 30 years, not 300.

Actually, I discussed a method that can handle all the different elements we would wish to handle. I'm not sure what BF means here.
