A pumped, boiling cesium Nb-1 Zr contained loop was operated for 2014 hours at a boiling temperature of 1850 deg F, a subcooled temperature of 700 deg F, a flow rate of 0.84 gpm, and a vapor quality of 10 plus or minus 3%. Flow conditions selected for the loop operation approximate some of the state point and flow conditions of a high temperature Rankine cycle space power plant. The purpose of the cesium loop was to determine the corrosion and mass transfer effects of cesium on containment materials and to gain information on instrumentation and control problems of pumped, boiling alkali metal loops. Test equipment was designed, built, and operated to permit direct measurement of the following properties of cesium over the temperature range 1000 to 1800 deg F: (1) density, (2) vapor pressure, and (3) specific heat. Using these measurements, the properties of (1) enthalpy, (2) entropy, (3) vapor specific volume, and (4) latent heat of vaporization were calculated. (auth)
