Material reactivity. worths were calculated using the linear first-order perturbation codes, PERT-ilD (modified to Include leakage, corrections for C and H), PERT-2D, and the one-dimensional discrete ordinate transport code ANISN. The radial and axial forward and adjoint angular fluxes used in the PERT-ID and PElftT-2D codes were obtained with ANISN and DOT, respectively.

Because of the wide range of designs considered, only representative results are presented in this summary. Figure 1 presents Keff Versus spacing for Connecticut Yankee fuel for the rack designs indicated. For one design, a comparison with an NUS Corporation Monte Carlo calculation is shown. Limited comparison with 2-D discrete ordinate transport theory calculations now fn progress will be presented.. ...
