CFD Analysis of Downcomer of Nuclear Reactor VVER 440
Journal Title: Strojnicky casopis - Journal of Mechanical Engineering - Year 2016, Vol 66, Issue 2
Abstract
The paper is focused on CFD analyses of the coolant flow in the nuclear reactor VVER 440. The goal of the analyses is to investigate the influence of the orifice diameter on the mass flow through individual fuel assemblies in the reactor core. The diameter of orifice can be changed during the operation of a nuclear power plant. Considered boundary conditions in the investigated region of the coolant are based on nominal coolant flow conditions in the nuclear reactor VVER 440.
