But in terms of processes, this diagram is too simplistic. What about all the attached chemical plant required for semi-continuous on-line fuel reprocessing?

But in terms of processes, this diagram is too simplistic. What about all the attached chemical plant required for semi-continuous on-line fuel reprocessing? Keeping that safe, leak-free and coping with the activation of all the pipework and processing equipment is a huge engineering challenge. Don't get me wrong, I love the simplicity of the LFTR reactor, but keeping the reactor running at scale requires a lot of additional infrastructure around it, and that's the hard part.
