Abstract

The naval industry has integrated the generation of energy through nuclear processes, due to the large amount of energy that is produced in these processes, for example, the ship NS OTTO HAHN, which used a propulsion plant with energy generated by a reactor of pressurized water (PWR), which operated under a nuclear fission process. Also, other examples are military ships and icebreakers. In order to know the energy contribution of this type of nuclear propulsion plants, this work carries out a multiphysics analysis of a PWR reactor, considering a turbulent behavior for the fluid that comes into contact with the uranium rods. Finally, the results of the fluid velocity fields along the fuel elements and the outlet nozzles are presented, as well as the temperature fields inside the reactor.
