Abstract

VVER-440 reactors have been utilized in Slovakia since 1978. Up to now, the length of their operating cycle has not change. This paper presents a proposal of extending the cycle from 12 to 14 months. Main attention is paid to the selection of the equilibrium fuel cycle. In this selection, the current fuel was considered with respect to relevant limits.
