Abstract

The latest version of Russian fuel VVER-440 includes burnable absorber in 6 pins. In this article is
impact of burnable absorber on nuclide composition and criticality analyzed. In part 1 was analyzed
whole burnup interval 0 – 50 MWd/kgU ³. In present part 2 are detailed analysis only for first cycle
(burnup 0 – 10 MWd/kgU)
