Description
Application of Gd2O3 in form of burnable poison particles (BPPs) has been investigated for improving neutronics performance of VVER-1000 fuel assembly. Numerical calculations have been conducted for optimizing BPP parameters using the MVP code and the JENDL-3.3 data library. The results show that by using Gd2O3 particles with the diameter of 60 μm and the packing fraction of 5% the burnup reactivity curve and pin-wise power distribution are obtained approximately that of the reference design. To minimize power peaking factor (PPF), two models of assembly consisting of 18 BPP-dispersed rods have been selected so that the burnup reactivity curve is approximate that of the reference one, while the PPF decreases from 1.167 to 1.105 and 1.113, respectively.
