fuel management issues


4 units of Paks NPP operate with 15m cycle since 2016. 4.7 and 4.2% enriched fresh fuel assemblies are used and the cycle length is regulated by application of differently enriched fresh fuel. There is a project in progress to verify safety of optimised fuel for Paks, fuel with reduced pin outer diameter and sold pellets. The paper gives some outlook of project status, the plans of transient cycles of Paks NPP and main behaviour of core containing optimised fuel.
