Popis: Denatured reactor plutonium with a 238 Pu isotopic content of ∼6% or somewhat more can be produced in a suitably adapted fuel cycle. Several such fuel cycle options are proposed. Reenriched reprocessed 235 U/ 236 U/ 238 U, which can be blended with some low-enriched 235 U/ 238 U fuel, leads, after one burnup cycle of 50 to 60 GWd/tonne in a pressurized water reactor (PWR) core, to denatured reactor plutonium with more than 8% 238 Pu isotopic content. Presently existing reactor plutonium with ∼2.8% 238 Pu from spent fuel with a burnup of 50 GWd/tonne can also be converted in PWRs, during one or two burnup cycles over 50 to 60 GWd/tonne into denatured reactor plutonium. This is also demonstrated by burnup calculations for different fuel cycle scenarios using, e.g., reenriched reprocessed uranium, thorium, and minor actinides. Denatured reactor plutonium with 6% or somewhat more 238 Pu isotopic content can be considered as a proliferation-resistant fuel and could be treated like low-enriched (
