I've been under the impression that reactor fuel is of a complelty different isotopic nature to that found in the nuclear devices.
It has a much lower enrichment %. A partially used fuel rod may be 90% unenriched U238, 3% U235, 3% Plutonium, 4% decay bi-products. And to a large extent, it is the caesium and strontium biproducts that were the pollution issues.
