Lattice Codes Pin Power Prediction Comparison

Nodal neutron diffusion codes relay, in their pin powers predictions, on data pre-calculated on fuel assembly basis using 2D transport codes. That is true for both, steady state (design and in-core fuel management) and transient, core pin power distribution. Beside the assumptions used during pin power reconstruction, final results depend on the accuracy of performed 2D transport depletion calculation. In the paper different 2D spectral codes were used to calculate pin power distribution for reflected single fuel assemblies during depletion. The prediction capabilities of the codes are compared for infinite multiplication factor, and for 2D pin power form factors.
