Measurements have been made of the amount and chemical and radiochemical composition of fuel element crud deposits from a number of modern commercial pressurized water reactors. Results from the Point Beach and Beznau I plants show that crud buildup is low, but variable from core to core. The buildup appears greatest in the first core cycle and less thereafter. The chemical composition of the crud cannot be predicted directly from the composition of the corroding surfaces. The radiochemical composition indicates high crud mobility. The results will be used as input to crud transport models for assessing plant radiation level buildup in future work.
