TWR　can　make　use　of　non-enriched　fuel　and　obtain　very　high　burnup　without　the　need　of　fuel　reprocessing.　TWR　is　an　effective　way　of　fuel　utilization　besides　the　closed　fuel　cycle.　In　this　paper,　the　feasibility　of　MA　transmutation　in　a　TWR　was　analyzed　to　further　excavate　the　fuel　utilization　of　this　type　of　reactor.　MA　was　homogeneously　charged　in　the　self-designed　1　250　MWt　board　type　radial　fuel　shuffling　sodium　cooled　TWR　core,　and　the　MA　weight　fraction　is　from　2.0%　to　12.0%.　A　self-developed　MCNP-ORIGEN　coupled　code　was　applied　to　perform　burnup　calculation.　The　results　indicate　that　the　transmutation　amount　increases　linearly　with　the　MA　weight　fraction,　while　the　transmutation　rate　parabolically　varies　with　the　increase　of　the　MA　weight　fraction.　Neutronic　safety　parameters,　such　as　the　core　effective　multiplication　factor,　Doppler　feedback　coefficient,　void　worth　coefficient　and　effective　delayed　neutron　fraction,　were　compared　under　different　MA　weight　fractions.　The　results　indicate　that　the　core　effective　multiplication　factor　and　the　void　worth　coefficient　increase　with　the　MA　weight　fraction,　while　the　Doppler　feedback　coefficient　and　the　effective　delayed　neutron　fraction　decrease　with　the　increase　of　the　MA　weight　fraction.　©　2015,　Atomic　Energy　Press.　All　right　reserved.
