  2. MOTIVATION • Study of thorium cycles and its application on VVER-440 reactor • Decrease of plutonium production, plutonium transmutation VUJE , Inc., Okružná 5, 918 64 Trnava, Slovakia; FEI STU, Ilkovičova 3, 81219 Bratislava, Slovakia

  3. SCENARIOS Pu-Th mixed oxide fuel cycle (VVER-440) ThOX Pu - all isotopes 9.74 wt% Pu (5.40 wt% Pu-239) STORAGE PuThOXFabrication VVER-440(PuThOX core) Reprocessing UOX U 1.24 wt% Pu FPMA0.1% Pu0.1% U UOXFabrication VVER-440(UOX core) URT 4.2 wt% U-235 PuThOX Waste Enriched U VUJE , Inc., Okružná 5, 918 64 Trnava, Slovakia; FEI STU, Ilkovičova 3, 81219 Bratislava, Slovakia

  4. SCENARIOS U-Pu-Th mixed oxide fuel cycle ThOX Pu - all isotopes U - all isotopes UPuThOXFabrication VVER-440(UPuThOX core) STORAGE Reprocessing (U,Pu,Th)OX FPMAPu0.1% U UOXFabrication VVER-440(UOX core) Wastes URT 4.2% U-235 FPMA0.1% Pu0.1% U U UOX Reprocessing VUJE , Inc., Okružná 5, 918 64 Trnava, Slovakia; FEI STU, Ilkovičova 3, 81219 Bratislava, Slovakia

  5. COMPUTATION MODELS Model of homogeneousVVER-440 assembly Model of advancedComposite VVER-440 Assembly - MoCA VUJE , Inc., Okružná 5, 918 64 Trnava, Slovakia; FEI STU, Ilkovičova 3, 81219 Bratislava, Slovakia

  6. SCENARIOS VVERT fuel cycle The uranium was added to blanket because natural thorium does not includea fissile component, enriched uranium is required to provide a reasonable power density in the blanketduring the initial periodof U-233 buildup VUJE , Inc., Okružná 5, 918 64 Trnava, Slovakia; FEI STU, Ilkovičova 3, 81219 Bratislava, Slovakia

  7. INPUT DATA target burnup: core cycle:50 GWd/tHM 320 fpd, 5 years VUJE , Inc., Okružná 5, 918 64 Trnava, Slovakia; FEI STU, Ilkovičova 3, 81219 Bratislava, Slovakia

  8. VUJE , Inc., Okružná 5, 918 64 Trnava, Slovakia; FEI STU, Ilkovičova 3, 81219 Bratislava, Slovakia

  9. RESULTS Potencial of Pu transmutation seed 4.2% U-235 seed 7.0% U-235 VUJE , Inc., Okružná 5, 918 64 Trnava, Slovakia; FEI STU, Ilkovičova 3, 81219 Bratislava, Slovakia

  10. RESULTS MA content in the fuel (g/tHM) VUJE , Inc., Okružná 5, 918 64 Trnava, Slovakia; FEI STU, Ilkovičova 3, 81219 Bratislava, Slovakia

  11. CONCLUSIONS • UPuThOX equilibrium cycle offers highest Pu transmutation ratio from selected scenarios • Composite assembly with Th fuel in the blanketdo not offer better plutonium generation rate asany of all selected fuel scenarios;it brings only lowest MA production per produced energy VUJE , Inc., Okružná 5, 918 64 Trnava, Slovakia; FEI STU, Ilkovičova 3, 81219 Bratislava, Slovakia

  12. Thank you for your attention VUJE , Inc., Okružná 5, 918 64 Trnava, Slovakia; FEI STU, Ilkovičova 3, 81219 Bratislava, Slovakia
