Sodium was pumped through a loop constructed of type 316 stainless steel with a Hastelloy X heater leg and an Inconel pump cell to determine the ability of an essentially bimetallic system to resist corrosion and mass transfer. (The Incone) Pump was considered to have no effect on the basic system). The loop contained a heater and a cooler section so that temperature gradients could be established in the sodium in the direction of flow. This loop operated for 305 hours at a maximum sodium temperature of 1700 deg F while maintaining the minimum sodium temperature of 1050 deg F. Posttest analysis revealed a msximum depth of attack of 3.5 mils in the Hastelloy X heater leg and deposits up to 32 mils in depth in the cooler which consisted pri-marily of nickel and chromium. A cold trap, located in the minimum temperature isothermal zone of the loop was maintained at 700 to 750 deg F in an attempt to remove sodium oxide contamination in the fluid. (auth)
