Abstract Experimental stress analysis was performed on design aspects of the loading-face shield not amenable to theoretical analysis. Strain and load data obtained from deflection tests of an aluminum model were used to derive bending-stress coefficients for different sections of the shield; maximum strains were recorded at inner edges of moderator-removal holes. Concrete specimens in which process-tube hole patterns were reproduced were tested in compression; strain-concentration factors as high as eight were recorded. Sleeves of practical proportions were found to be ineffectual in reducing diametric shortening of the holes. Transverse deflections of a plaster scale model were found to be 2 1/2 times greater than predicted by plate theory. On the basis of these investigations, maximum stresses in loading-face-shield concrete and steel were determined and factors of safety were calculated. Results of this analysis indicate that the shield will fulfill service requirements.
