I have questions regarding the normalization factor that is shown in Section 8.3 of the User’s Guide.
Let’s suppose that we have a hexagonal fuel assembly (see image), and a 3D regular mesh is created to tally the flux. This mesh will later be used to create an image of the flux distribution in the assembly, similar to the one shown in the example “Pandas DataFrame” for the fission rate (Out ). The power of the assembly is known, and we want to report and plot the flux in typical units “neutrons/cm2-s”.
As shown in that section, the system power is divided by the observed heating rate to obtain the normalization factor. My questions are:
To transform the flux units in each cell of the mesh and then plot the result, do we use the power of the assembly and divide by the heating rate tallied in each cell, or an average power for each cell of the mesh should be determined and then divide by the heating rate tallied in each cell?
In this case, what is the volume used to get the flux in typical units, the volume of the hexagon, or the volume of each cell of the mesh?
Thank you in advance,
