Abstract

A simple theoretical model is proposed in this paper based on an analysis of the experimental data available in the available literature. It describes the rate of mass loss during the dissociation of uranium nitride in a vacuum and in a gas atmosphere due to the evaporation of substances from the surface of materials. The proposed model can be used to assess the degree of dissociation of uranium nitride, which is one of the main causes of fuel destruction, since congruent melting is observed only at high nitrogen pressures.

高温下氮化物燃料解离速率的计算模型

摘要

在对现有文献中可用的实验数据进行分析的基础上，本文提出了一种简单的理论模型。它描述了由于物质从材料表面的蒸发，在真空和气体气氛中氮化铀解离过程中的质量损失率。所提出的模型可用于评估氮化铀的解离程度，这是燃料破坏的主要原因之一，因为仅在高氮气压力下才能观察到完全熔化。
