Abstract

This paper considers the effect of nozzle spacing on the pressure stresses at cylindrical pressure vessel shell and nozzle junctures. This consideration is based on a photoelastic test conducted to determine if the stress indices of Section III of the ASME Boiler and Pressure Vessel Code may be used in analysis of reactor vessel designs containing circumferential nozzle spacings smaller than presently allowed by the Code. The five circumferential spacings used in the test were 109 deg, 34 deg, 30.2 deg, 26.4 deg, and 22.5 deg. The stresses at the locations of interest are presented as a function of nozzle spacing. These results show that the maximum stresses for spacings below the Code minimum are smaller than those at the Code minimum.
