The Physics of Critical Heat Flux Studies for Innovative ATF Cladding Surfaces*

Overall Objective
The goal of this project is to investigate the engineering physics phenomenon of critical heat flux (CHF) for surfaces of accident tolerant fuel (ATF) cladding materials that are being considered for implementation jointly by industry, utilities, and the Department of Energy (DOE). This effort involves testing at small scale in a pool boiling environment and testing at intermediate scale in flow boiling under prototypical conditions, along with associated analysis.
