Abstract

Abstract

FeCrAl is proposed as one of the candidate materials of accident tolerant fuel (ATF) cladding, which can suppress hydrogen generation under severe accident condition, and improve reactor accident tolerance. In this paper, the boiling heat transfer behavior of FeCrAl and Zr-4 during quenching is studied based on visualization method. The surface heat flux and temperature of FeCrAl are calculated by solving one-dimensional inverse heat conduction problem, and the effects of surface oxidation and solid thermophysical properties on the quenching behavior of FeCrAl are analyzed. The results show that as the liquid subcooling degree increases, the quenching duration of FeCrAl is decreased, and the minimum film boiling temperature increases. With the increase of solid thermophysical property (ρc_p)_w, the quenching duration increases and the minimum film boiling temperature decreases. Because of the excellent high-temperature oxidation resistance of FeCrAl, the effect of surface oxidation on its boiling heat transfer behavior during quenching can be ignored.
