Values of the resonance escape probability in 0.387-in. diameter, 2% U235-98% Th232 light-water moderated lattices have been measured. The results are p = 0.821, 0.859, 0.889, 0.918, 0.937 for water/metal volume ratios 1, 1.5, 2, 3, 4. These values are somewhat higher than corresponding ones measured in similar slightly enriched uranium lattices.
