Description
Supercritical Water-cooled Fast Reactor (SCWFR) presents features of combining fast and light water reactor characteristics in one design. The coolant mass flow rate is just as 1/8 as in the BWR, and the neutron energy is harder than in PWR, so it would has the breeding ability. In this paper, using different models of improved Flower-SCWFR core, the void reactivity effect, power distribution,and breeding ratio are analyzed by core zoning scheme, axial coolant densities zoning,seed and blanket assembly with suitable P/D value, MOX fuel with different design and enrichment zoning, and solid uranium matrix cooled by internal clad channels in blanket assembly. Finally, an optimized modal of the improved SCWFR cores-'Flower type' is obtained. (authors)
