Abstract

The high-temperature saturated vapor pressure of the nuclear fuel material UO2 is an urgently required input parameter for reactor accident studies. The authors have developed a pulsed laser technique whereby solid uranium dioxide surfaces are irradiated with laser radiation of 104-107-W cm−2 intensity. The resulting material removal rate, which is determined by measuring the crater depth (~50μm) and laser pulse width (~200 μsec), is related to the saturated vapor pressure through the Hertz-Knudsen-Langmuir equation with unit evaporation coefficient. The validity of the interpretation requires a detailed analysis of the following phenomena.
