Is the radial peaking factor same as normalized radial power profile?
Thanks Astronuc.
Is it defined at each axial/radial position? Suppose I have a power profile of a single pin. How do I find out the peaking factors at various locations in the axial and radial direction?
A peaking factor would be determined from the local power density (or linear power) divided by the core average power density (or linear power). The average power density is found from the thermal rating of the reactor core divided by the total length of active fuel. The local power density is calculated with a core simulation code (e.g., SIMULATE or other proprietary code) which solves a multi-group neutron diffusion or transport problem. The codes calculate the neutron flux and local enrichment, which includes effects of depletion and transmutation, and from these determine the fission density, from power density is calculated.Thanks Astronuc.
