Investigation of severe pitting of slugs and tubes in the Hanford piles. Revision
During the summer of 1952 a series of leaking process tubes and badly pitted slugs was encountered in the Hanford piles. In August 1952, a program was initiated to determine the mechanism of the observed attack and to determine what corrective measures could be taken. Two suggested hypotheses, cavitation and erosion-corrosion, were considered the most practical explanations of the observed attack. Flow laboratory investigations of these hypotheses conclusively showed that erosion-corrosion in uninhibited process water was the cause of the excessive attack noted. The addition of an inhibitor, 2 ppM sodium dichromate, to the water resulted in the complete elimination of the erosion-corrosion attack on the aluminum slugs and tubes. 5 refs.
