Not a major issue, but a minor inconsistency that I noticed. Plutonium-rich nuclear waste solution and uranium nuclear waste solution are fluids, and should probably be categorized under the Fluids category (they currently appear under Unsorted, which can be seen in the Factoripedia and while setting circuit conditions).
Secondly, the recipes "breeder-fuel-from-uranium-cell" and "breeder-fuel-cell-from-MOX-fuel-cell" are labelled as unknown keys (they appear under the Factoripedia as well as the centrifuge itself).
