Determination of the flow velocity in a boiling water reactor (BWR) via cross-correlation of the fluctuating signals of two in-core detectors has prompted several investigations aimed at evaluation of the detector field of view (FOV). Questions have been raised about the degree of material homogenization and the importance of transport theory effects. In a previous paper, the authors concluded that a cell-homogeneous model is adequate for determination of the adjoint function distributions. In the present work, the authors have investigated the importance of transport theory effects using a combined R-Z transport and X-Y-Z diffusion theory model. These calculations indicate that diffusion theory is sufficient for the prediction of the FOV of a BWR in-core detector.
