Proper simulation code for a Nuclear Reactor core


There's been a lot of discussion, but if you want to get reasonable results and you only need to run the calculation once, go back to comment 1.
You will need to come up with a temperature distribution, then set up a Serpent model.

That's an interesting and useful document. Looking at page 20/50, it seems the authors switched the descriptions of the neutron spectra. The spectrum on the right is the flux, and the one on the left is the fission spectrum. The core is mostly fast flux, with small thermal component, and that would be toward the outer edge of the core adjacent to the BeO reflector.

Note: "Spectrum is very fast, such that changes in cross sections with temperature are largely insignificant, >90% of feedback is dimensional changes due to thermal expansion."
