Overview on space-time core calculationsfor VVER reactors

Grundmann, U.

Transient analyses for VVER reactors performed with the computer code DYN3D are described. The decay heat after the shutdown of a VVER-440 is considered. A Xenon oscillation transient in a VVER-1000 is presented. The results for control rod ejections and control rod withdrawal in VVER-440 and VVER-1000 reactors are shown. A boron dilution transient in a VVER-440 by using the coolant mixing model of DYN3D is presented.

Keywords: VVER reactors; transients; analyses; three-dimensional core model; feedback; reactivities
