Abstract

The paper presents results of nuclear criticality safety analysis of spent fuel storage and
handling for the 1st and 2nd unit of NPP Mochovce. Spent fuel storage pool (compact and reserve
grid) and T-12 transport cask were modeled using the Monte Carlo code MCNP5. Conservative
approach was applied and calculation of max
eff k values was performed for normal and various
postulated emergency conditions in order to evaluate the final maximal max
eff k values. The
requirement of current safety regulations to ensure 5% subcriticality was met except some
especially conservative cases.

Keywords
