Abstract

The ?Full-Core? VVER-440 pin power distribution calculation benchmark was proposed by Mr.
Mikol?? on the 21st Symposium of AER in Dresden in 2011⁴. This benchmark is a 2D
calculation benchmark based on the VVER-440 reactor core cold state geometry with taking into
account the geometry of explicit radial reflector. The main task of the benchmark is to test the
pin by pin power distribution in selected fuel assemblies at the periphery of the VVER-440 core.
In this paper we present our calculations (keff, pin by pin power distribution, integral fission
power) made by MCNP and the KARATE code system in the Centre for Energy Research, the
analysis of our results and some conclusions.
