Three dimensional heterogeneous finite element method for static multi‐group neutron diffusionAydogdu, Elif Can 01 August 2010 (has links)
Because current full‐core neutronic‐calculations use two‐group neutron diffusion and
rely on homogenizing fuel assemblies, reconstructing pin powers from such a calculation
is an elaborate and not very accurate process; one which becomes more difficult with
increased core heterogeneity. A three‐dimensional Heterogeneous Finite Element
Method (HFEM) is developed to address the limitations of current methods by offering
fine‐group energy representation and fuel‐pin‐level spatial detail at modest
computational cost. The calculational cost of the method is roughly equal to the
calculational cost of the Finite Differences Method (FDM) using one mesh box per fuel
assembly and a comparable number of energy groups. Pin‐level fluxes are directly
obtained from the method’s results without the need for reconstruction schemes. / UOIT
