Yes, the problems are many, including entropy. Achievable today are spreading-out and confining fuels and wastes in tiny quantities using lithographic techniques similar to IC production. Molten salt SMRs solve some problems, but they still don't adequately contain radioactivity in fixed areas as well as heatpipe SSRs (i.e., eVinci) do. Heatpipe SSRs furthermore aren't as good at inherent containment and safety as SSR lithographic cell reactors, which contain minuscule amounts of fissile material/waste per unit volume embedded in chunky, rugged substrates comprising a very small module, reprocessed as a whole. Many, many modules linked together then represent a genset, from large to small. If modules can be standardized, they could be distributed as highly-controlled items as "batteries" for numerous applications. In the long-term, fusion is The Way™.
