Internal stresses caused by non-uniform swelling of fissionable material

This paper examines a new cause of macro-stresses of the first kind in fuel elements-namely, nonuniform swelling of the fissionable material, caused by the fact that, owing to “corrosion” of the neutron flux, the amount of fission products formed is not uniform across-section of the fuel element. The authors give methods of calculating the magnitudes of the stresses. They note cases in which the stresses have an appreciable effect on the efficiency of the fuel element.
