15. But how do you get sea water all the way to Oklahoma, kansas, North and South Dakota etc. etc.?

How many of these traveling wave reactors are there or is it another of those that sounds good on paper or has been made to kinda work in a lab somewhere? Sounds like its something we don't even want to fuck with let alone use it as an example of what can be done

Kirk Sorensen of Flibe Energy has criticized the TWR as "a particularly difficult implementation" of the fast breeder reactor, which he characterizes as "already hard to build in the first place." As well, he has emphasized the enormous difficulties and risks associated with the eventual nuclear decommissioning of a TWR reactor.[16] Dr. Robert Hargraves, who is on the Flibe Energy Board of Advisors,[17] lauded the goal of addressing energy poverty globally with the TWR, but briefly highlighted that its projected cost of energy production, "competitive with [conventional] nuclear power", wasn't as low as fossil fuels (e.g. coal).[18]


We're talking about a need for a change in the way we're producing our electricity not an experiment that may or may not work. Even with reprocessing there's still that sticky subject of nuclear waste, something that we really don't have any answers for yet. If I remember correctly the waste you finally wind up with after reprocessing has less volume but much longer lived, ie more dangerous to future inhabitants
From wiki
Nuclear reprocessing technology was developed to chemically separate and recover fissionable plutonium from irradiated nuclear fuel.[1] Reprocessing serves multiple purposes, whose relative importance has changed over time. Originally reprocessing was used solely to extract plutonium for producing nuclear weapons. With the commercialization of nuclear power, the reprocessed plutonium was recycled back into MOX nuclear fuel for thermal reactors.[2] The reprocessed uranium, which constitutes the bulk of the spent fuel material, can in principle also be re-used as fuel, but that is only economic when uranium prices are high. Finally, a breeder reactor is not restricted to using recycled plutonium and uranium. It can employ all the actinides, closing the nuclear fuel cycle and potentially multiplying the energy extracted from natural uranium by about 60 times.[3][4]

Nuclear reprocessing reduces the volume of high-level waste, but by itself does not reduce radioactivity or heat generation and therefore does not eliminate the need for a geological waste repository. Reprocessing has been politically controversial because of the potential to contribute to nuclear proliferation, the potential vulnerability to nuclear terrorism, the political challenges of repository siting (a problem that applies equally to direct disposal of spent fuel), and because of its high cost compared to the once-through fuel cycle.[5] In the United States, the Obama administration stepped back from President Bush's plans for commercial-scale reprocessing and reverted to a program focused on reprocessing-related scientific research.[6] Nuclear fuel reprocessing is performed routinely in Europe, Russia and Japan.


I'm not sure you will sell very many on using MOX fueled nuclear power plants
