I am doing a research project on the integral fast reactor, developed at Argonne. I understand that a big part of the IFR concept is that the reactor's waste is reprocessed. Throughout my research, I have come across the mentioning of "pyroprocessing." Could you explain what pyroprocessing is, and how it works?
We do not have a general non-technical write-up on pyroprocessing but by searching “nuclear reprocessing” in Wikipedia it gives a general description of the technology and a few links.
More information about pyroprocessing (including an online pdf brochure) is available at
I hope these help.
