I don't want government money spent on building more PUREX plants.
I would rather see the money spent in R&D on a more reasonable plan.
I think one could assemble a processing plant using many of the same techniques as we plan to use for LFTR.
The major difference being a high uranium capacity front-end.
I would expect we can provide as separate streams:
Xe (I think by this point non-radioactive since Xe isotopes either have short half-lives <36 days or long ones >1e14 years)
Kr (still radioactive so it ought to be stored for 100 years)
U (?can be used in HW reactors or enriched for LWRs but some comments about it being too radioactive for normal handling in enriching)
Np (useful to generate Pu238 but we probably would swamp the market)
noble metals (Zn, Ga, Ge, As, Nb, Mo, Tc, Ru, Rh, Pd, Ag, Cd, In, Sn, Sb)
Zr (comes off early in the vacuum distillation step)
THE REST (Rb, Cs, Sr, Ba, Y, the lanthanides) PLUS actinides (Thorium, Americum and Curium)
For processing LWR SNF there is no thorium and the burnup is low enough that there is only a small amount of Am or Cm. I would prefer that we could remove it but we can save that job for another decade. We still have removed 99+% of the actinides.
Unfortunately, THE REST includes both Cs137 and Sr90 so it will include the major heat sources.
