ABSTRACT
4 Units of Paks NPP are planned to operate in 15 month cycles. The number of fresh fuel planned for this cycles is 102/unit/cycle. In this work we tried to improve fuel demand of 15m cycles, the goal was to establish 90 assembly/cycle strategies. For this purpose different developed assembly structure was investigated. Appropriate enrichment is determined, CCS libraries was generated to different versions and equilibrium cycles are arranged. Fresh fuel cost and benefits are calculated for each version.
