[1E_PL] Current Understanding of Nuclear Fuel Behavior at High Temperatures, Including Transient and Accident Conditions

[1E_PL05] Discussion

Accurate evaluation of nuclear fuel behavior at temperatures above 2000 K and near the melting point requires reliable thermophysical-property data and their appropriate incorporation into analytical models. This session reviews the current status and limitations of high-temperature property measurements, theoretical and experimental studies near melting, molten-fuel properties, and the effects of property uncertainties on fuel-behavior analyses, and discusses future experimental and omputational needs.
