FALCON 2022 CRS4 contribution: ALFRED two phase CFD model

This document reports and describes the in-kind contribution of CRS4 to the FALCON consortium for the year 2022. A complete CFD model of the ALFRED primary coolant flow path is built, without taking profit of geometrical symmetries and representing both the Lead and the Argon phases under the framework of the Volume of Fluid (VoF) approach. The model makes also use of the volume interface feature allowing to provide the model with fuel and secondary coolant dedicated volumes. The main peculiarities of the model are explained. The model is used to simulate a full power steady-state and then to simulate a pump trip from the steady state configuration with two different resistance coefficients of the tripped impeller.
