This paper presents the results of steam exposure tests of 316 stainless steel in the Fusion Aerosol Source Test (FAST) facility. The tests were performed at temperatures of 500, 600. 700, and 800{degrees}C. These tests were conducted to measure the mobilized material resulting from the steam exposure conditions at each temperature. A steam volume flow rate of 21-27 standard liters per minute was maintained in the test sections for a duration of 5 hours. These conditions simulate postulated accident conditions in the International Thermonuclear Experimental Reactor (ITER) relevant scenarios. These data will be used in safety assessments for ITER. The authors compared the data obtained in these tests with data from the Volatilization of Activation Product Oxides Reactor (VAPOR) facility at 800{degrees}. The data obtained in the tests show the following: (1) There is a progressive increase of measured mass flux for Fe, Mo, Mn, Zn, and Cr with test temperature between 500{degrees}C and 800{degrees}C. (2) Mass flux measurements from FAST and VAPOR agree within a factor of three for elements with volatile oxide or hydroxide species such as Cr and Mo. (3) Mass fluxes of elements associated with oxide spalling in VAPOR, mainly Fe and Mn, were up to a factor of 90 lower in the FAST test than in the VAPOR test at 800{degrees}C. (4) Detection limits in FAST were lower than those measured in VAPOR due to the larger surface area of the source in FAST tests. 1 ref., 4 figs., 1 tab.
