An analysis of the melt casting of the melt casting of metallic fuel pins

摘要

A model is developed and analyses are conducted to analyze the casting of metallic fuels pins. The important physics of the model includes the flow of the melt into the mold, the heat transfer into the mold, the amount of preheating in the mold, and the rate of heat transfer from the melt to the mold. This paper discusses and presents preliminary modeling results for the casting of long, slender fuel rods. Parametric modeling results are presented and discussed.
