Experimental and calculated activation shapes were compared along a traverse through the heterogeneous dimension of a slab core homogeneous in the other two directions. The core featured a 20-inch Zr--H/sub 2/0 reflector region on. one side. Bare Mn foils and Cd-covered In, Au, and depleted U-238 foils provided experimental data throughout the reflector and the adjacent fuel region. Calculations utiIized few group P-1, multigroup P-1, several group P-3 and thermal multigroup double P-1 approximations to obtain flux values. Multigroup detector cross sections were also obtained. The use of P-3 fast and epithermal fluxes in the Zr--H/sub 2/O reflector is shown to be necessary to match experiments. The activation shapes of Cd-covered In and Au are shown to be insensitive to the variation of the foil cross sections with energy in the Zr--H/ sub 2/O reflector. (auth)
