Modified Candle ReactorsIn this study conceptual design study of Pb-Bi
cooled fast reactors which fuel cycle need only natural uranium input has been performed. In this case CANDLE burn-up strategy is slightly modified by introducing discreet regions.
In this design the reactor cores are subdivided into several parts with the same volume in the axial directions.
The natural uranium is initially put in region 1, after one cycle of 10 years of burn-up it is shifted to region 2 and the region 1 is filled by fresh natural uranium fuel.
This concept is basically applied to all regions, i.e. shifted the core of I’th region into I+1 region after the end of 10 years burn-up cycle .
