I am a massive LFTR stan, but we have to recognize that, EROEI aside, the total economics of nuclear aren't competitive in the current regulatory framework in the US versus alternative energy. I agree that theoretically those EROEI figures are correct/achievable, but PWR/LWR has so poisoned the brand of fission that we can't get those right now.

We'll need a stable price target (and maybe paranoia of the Chinese) to get LFTR and better reactor design actually economical and the necessary political reforms.
