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.
Highlights
Nuclear propulsion systems have been investigated due to the large amount of energy they generate, despite this, there are certain factors by which the energy generated cannot be used efficiently
The radial profile of the temperature of the fuel rod in a pressurized water (PWR) reactor that you must obtain in the computational results, must follow the same trend as shown in Fig.5, since these are the curves of the typical radial temperature profile [3]
The results obtained in the first global study, the highest temperature is in the center of the fuel elements; these temperatures vary according to the location of the rod and time, for example, in Fig.14, the radial temperature profile is shown in 2 rods that are in different locations in a time of 60 seconds
Summary
Nuclear propulsion systems have been investigated due to the large amount of energy they generate, despite this, there are certain factors by which the energy generated cannot be used efficiently. The results of the local study are the basis for developing the global study on fuel elements and the PWR, to carry out an energy analysis.
