„FULL CORE“ BENCHMARK FOR VVER-440
23rd Symposium of AER on VVER Reactor Physics and Reactor Safety (2013, Štrbské Pleso, Slovakia)
Reactor physics experiments and code validation (benchmarks)
Abstract
Because of difficulties with experimental validation of power distribution predicted by
macro-code on the pin by pin level we decided to prepare calculation benchmark named
?FULL-CORE? VVER-440. 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 this benchmark is to test the pin by pin power distribution in
fuel assemblies predicted by macro-codes that are used for neutron-physics calculations
especially for VVER-440 reactors.
The submission of this benchmark was presented on the 21st Symposium of AER in
2011. The reference solution has been calculated by MCNP code using Monte Carlo method
and the results has been published in the AER community. The results of reference calculation
were presented on the 22nd Symposium of AER in 2012.
In this paper we will compare available macro-codes results of this calculation
benchmark.
