Behaviour of particles of U, UO2, and UC2 in a vertical tube through which liquid sodium is flowing.

Abstract

This paper sets out to calculate the relation between the particle velocity and the fluid velocity in a vertical tube without making any assumptions as to the "apparent" viscosity of the suspension of particle in liquid sodium. The theory and calculations method is developed for suspensions of U, UO2 and UC2 in liquid Na in the temperature range 200º - 800ºC. At the moment, it does not help in assessing the performance of a circulating suspension in the primary coolant stream of nuclear power reactor
