THERMOGALVANIC EFFECTS BETWEEN ALUMINUM SLUG JACKETS
The severity of attack of an aluminum slug jacket containing one or more spots decidedly hotter than the remainder of the jacket, conditions likely to exist in a poorly bonded slug, is investigated. A thermogalvanic cell is devised for heating the aluminum cans immersed in pile process water to various temperatures in a manner to simulate thermogalvanic couples believed to exist on fuel slug surfaces under pile operating conditions. The thermogalvanic currents and potential differences are measured and recalculated to rates of corrosion. Assuming uniform attack, a corrosion rate of 0.4 mil per month is calculated for a can maintained at 100 deg C and galvanically coupled to a similar can at 20 deg C. (N.W.R.)
