I guess we will just have to agree to disagree since I am quite positive that we have reached the level of technical maturity,(at least here in the west) to safely handle radioactive materials. I am also pretty sure that without the anti-nukes spreading lies hither and yon, the politics would soon catch up. So it seems the lack of maturity lies with the anti-nukes. Please understand that I refer to commercial systems, not military. So far, they seem to have bit of a problem taking care of their stuff.
I'd kind of like to see a UN Corporation that provides LFTRs at cost+%, under UN control, to any country that is willing to turn over all rights to nuclear research; i.e., they would agree not to do any nuclear research/development. The LFTR would be designed for optimum breeding with an emergency denaturing system to prevent diversion of fuel to weapons projects.
It need not be UN specifically, but it should include buy-in from all the major nuclear powers so that all agree that countries that attempt to violate their agreement are appropriately disciplined.
Kiteman; Your simple dismissal of the facts that illuminate what I have proposed does not relieve us from our obligations to hold fission accountable. Merely by accusing the anti-nukes as immature will require evidence that supports that accusation. Other wise it is dismissed as simple rhetoric.
You have reached a position that you are positive that we have reached our technological maturity for fissionable energy is just your opinion with no facts to support that position.
UN corporation for LFTR’s dispersals is interesting. However their record for maintaining security. as it is, a hit or miss dependent to the strengths of their adversaries. Thus terrorist would seek to obtain the fuel of these LFTR’s and then we can anticipate what that would entail.
Think GE has a program for that, they want to produce these mini atomic reactors for less fortunate energy deprived areas of the world. They face the same dilemma. How can they guarantee security 24/7 for life of the plant? Maturity level of the world is even less than what is in this nation.
Now once again; why such determination for a complex centrally controlled energy program, when the Sunshine is just outside your window. Individuals have the ability to be INDEPENDENT from central energy sources Temptations will forever be within a centrally controlled energy system to exploit their customers. Our Fusion Reactor is already on line and we call it the SUN. Each of us has the ability to extract that energy for less cost than any centralized energy system can ever accomplish for those of us, that choose INDEPEDENCE.

Brian; It was stipulated that you provide links to sources that demonstrates what your implying is correct. All you have offered is something about what you saw. Then you want me to cite something. NO, NO, NO, that’s not how it works. I have given you a site to find a greater knowledge for what you are trying to converse in. There are other sites but why bother look at you. Stumbling about asking others to give you the answerer and then you will not comprehend it and off on to another of some useless opinionate rhetoric.
You have to cross that lonesome valley all by yourself for no one can do it for you… Here try this; Just one small part of Paleoclimatology and one brief epoch of time. Go to Snowball Earth and study the theories that led us to that snowball . How did it get reversed? After all snow reelects the sun. This might make cheer you up. Observe what the atmosphere was. I know you’re a CO2 fan. Now that should not take more than about an hour of your time to study. Be careful though, knowledge is an addictive process.

Once again you have demonstrated the failure of your Fail Safe gizmo. Humans made the Fail Safe and Humans Are the prime causes of failure of systems. Paradox.“Its no Fail Proof”; that is no more than saying six of one ½ dozen of another. What this implies is a foundation is being laid for semantically dismissing various obstacles and highlight the benefits. Semantics aside there is no 24/7 /life of reactor guarantee that insures us that it will not continue to add to the radioactivity that is already a-washed world wide. Accumulation of radioactivity is compounding to the top of the food chain. When we get to space and safely out of orbit. Then we can fire up these fissionable reactors. There the probability of the humans employed will be matured enough to comprehend the nature of fissionable material. A simple safety feature to insure that the Earth is no longer threatened with additional radioactivity from these energy sources is to have them in an escaping orbital trajectory. Fail and off they go. Perhaps to the Sun if we should so choose. Adding any more radioactivity pollution to our fragile eco system is no longer tolerable from radioactive generators. Especially all the energy required falls from a huge Fusion Reactor and the pickings are easy and non TOXIC. No need for Fail Safe or worries of Terrorist pursuits.

No reply to my questions and my answers to yours go ignored? Is that how your preacher man advises you? Nay, nay never question and when questioned never answerer. Perhaps those other questions were too much for you. Lets get real Simple; {PUN} What I f Adam and Eve were the first two humans and only humans? Then we can deduce that their off springs would have to commit to incest to keep the ball rolling. Hmmm a religion based on incest? Hmm Oh I know abracadabra and hocus pocus and you can have your answerer to that question. Go ahead ask any preacher, priest, rabbi, etc. etc. Then watch how their magic works…

Your saying this suggests to me that you are not technically trained. The difference between fail proof and fail safe is not "symantics" it is the difference between what is technically increadible and technically achieveable.

Why should it? Radiation exists, gets created, and goes away. Adding small amounts to the existing field just takes us to where our species evolved. Small amounts are good for us. And yes, I do think there is a reason to believe that the generl level of world radioactivity will not go up, even if there are caverna and other geologic fetures where the level may go up significantly.

Radiation does not compound, but various chemicals do. Some of the chemicals may have radioactive isotopes, like Iodine. Iodine actually bio-accumulates... to a level. That is why it is so effective to take Iodine tablets if there has been an event like Fukushima (which, by the way, Liquid Fluoride Thorium Recyclers CAN'T have). The Iodine in the tablet fills the reservoir so to speak so the leaked radio-Iodine just washes thue the body. Other chemicals are bioactive but don't accumulate, like Cesium. But again, none of those chemicals can get released from LFTRs like Fukushima because LFTRs CAN'T melt down!

Kiteman states; “technically increadible and technically achieveable.”

BF] Does not answerer the question of a Fail Proof or Fail Safe system that I presented to you. There are no such thing in our humane existence. Achieving the incredible would be more accurate description.

KM; States; “Adding small amounts to the existing field just takes us to where our species evolved. Small amounts are good for us”

BF] We have already past the point of small amounts in the radioactivity that has spilled out. It will take thousands of years to return back to levels of naturally occurring radioactivity dispersions. Adding small amounts will increase that time frame and the biological destruction that we are presently suffering from.

KM States “ I do think there is a reason to believe that the generl level of world”
BF] No argument there. Both of us in agreement there.

KM States “Accumulation of radioactivity is compounding to the top of the food chain. Radiation does not compound, but various chemicals do.”

BF] Top of the food chain accumulates greater amounts of radioactivity by consumption of the vegetation and the animals that eat those vegetations as well. Thus compounding the destructive effects of the accumulating increasing radioactivity.

KM States “Some of the chemicals may have radioactive isotopes, like Iodine. Iodine actually bio-accumulates…”

BF] Iodine can be used to help flush some radioactivity. Problem is it does not remain and constant replenishment would be required. Hmm What would the effects be of abusive iodine chemicals to our bodies? Thyroid? Hmmm. And once again it does not flush out Strontium 90 from the blood or bones as well as radon and a few other radioactive compounds. That’s why its not a sure protection and is limited as to its use. Don’t so easily dismiss Cesium because its bioactive. That one compound alone in small amounts can be fatal. Regardless of your iodine pill.

KM States “But again, none of those chemicals can get released from LFTRs like Fukushima because LFTRs CAN'T melt down!”

BF] Oh great I was hoping not to divulge that secret to the terrorist.! What hell have you wrought upon us now..?
All of these complex shadowy devious ploys for fission, why? We have Fusion Energy raining down on us and blowing by us. Out there for easy pickings. Nor would we not be trading one Toxic Fueling System for another. We would be replacing Toxic systems with Sunshine which stimulates the Green to bloom. Now don’t that feel good and clean rather than that oily, coaly radioactive stuff we have been living in. You have problem with that????

Past global climate changes had strong regional expression. To elucidate their spatio-temporal pattern, we reconstructed past temperatures for seven continental-scale regions during the past one to two millennia. The most coherent feature in nearly all of the regional temperature reconstructions is a long-term cooling trend, which ended late in the nineteenth century. At multi-decadal to centennial scales, temperature variability shows distinctly different regional patterns, with more similarity within each hemisphere than between them. There were no globally synchronous multi-decadal warm or cold intervals that define a worldwide Medieval Warm Period or Little Ice Age, but all reconstructions show generally cold conditions between ad 1580 and 1880, punctuated in some regions by warm decades during the eighteenth century. The transition to these colder conditions occurred earlier in the Arctic, Europe and Asia than in North America or the Southern Hemisphere regions. Recent warming reversed the long-term cooling; during the period ad 1971–2000, the area-weighted average reconstructed temperature was higher than any other time in nearly 1,400 years.

Small greenhouses were used in the arctic to maintain Erioporum vaginatum-dominated tussock tundra for 10 wk at ambient CO"2 (340 @mL/L), elevated CO"2 (510 or 680 @mL/L), or elevated CO"2 and 4@?C above ambient temperature (680 @mL/L, ambient + 4@?).

The denier above repeats its lies for years and years. Here's science again saying otherwise:

"There were no globally synchronous multi-decadal warm or cold intervals that define a worldwide Medieval Warm Period or Little Ice Age."

Also:

When Keeling first began his measurements, the amount of carbon dioxide (also known as CO2) was 316 parts per million (ppm). As of Tuesday this week, the measurement was 398.44 ppm as measured at Mauna Loa.
