Abstract
The new benchmark for VVER-1000 control rod ejection transient was published recently. One of the assumptions proposed in the benchmark is given fixed values for fuel-cladding gas gap thermal conductivity and thermo-physical properties of fuel and cladding materials. In this paper, authors investigate an impact of this assumption on simulation results.
Keywords: X2; VVER-1000; Control Rod Ejection; fuel-cladding gas gap thermal conductivity; thermo-physical properties of fuel and cladding
