Numerical Modeling of Cladding Melt Motion over Surface of Fuel Pin of Fast Reactor for Various Fuels

Abstract

Methods of calculating the motion of melt over the surface of fuel element in accident conditions are presented. The calculation is performed using mathematical modeling methods. The results of calculating the melt motion and solidification on the fuel pin surface at various vapor flow velocities and for various types of fuel are shown.
