Last night I had a dream in which my job was to identify abandoned nuclear reactors, fuel rods, waste, for clean-up and
In the dream, I was particularly looking in Africa because many African governments had created reactors and because they were unstable they were abandoned when the government fell apart or was replaced.
At this point in our history, we had developed a technique for removing waste from soil and most other things and packaging it in a shipping container for treatment.
The treatment involved first extracting all the actinides from the fission products. The actinides would be burned in a fast reactor leaving only relatively short-lived fission products. The fission products would decay to safe materials in about 300 years versus a million years for waste containing actinides.
