TWO-GROUP DIFFUSION-THEORY CRITICALITY CALCULATIONS ON INTERACTING SLABS AND A BRIEF REVIEW OF THE THEORY USED
The results of calculations done on the critical sizes of interacting slabs are reported. Two-group diffusion theory is used, and the limitations of this method are discussed. The slabs were assumed to contain a fissile solution of H/U = 300. The slabs were infinite in two dimensions, and the center-to- center distance for criticality was calculated in terms of the slab thickness. Two geometrical configurations were used: that of an infinite array, and that of two interacting slabs. The medium between the slabs, the reflector, was assumed to vary, and results are quoted for water, a boron solution with varying resonance escape probability, and for wood impregnated with boron. The results in the limiting case of infinite separation, i.e., a single slab, are also given, and comparison is made with the experimental data available. (auth)
