Transuranic metals such as plutonium usually need to be protected in inert gases to inhibit oxidation and produce aerosols. In the paper, the oxidation reaction process of plutonium was depicted based on the point defect model. The aerosol generation rate was approximated to the oxidation rate of plutonium when the oxidation layer keeps constant. The results show that the rate is strongly dependent on the vacancy diffusivity and reaction rate constant of the vacancy generation and consumption. The aerosol generation rate at the temperature of 298 K is in the order of 108 particles/cm2/s.

金属钚氧化气溶胶生成的研究

超铀金属如钚通常需要在惰性气体中进行保护以抑制氧化并产生气溶胶。本文基于点缺陷模型描述了钚的氧化反应过程。当氧化层保持恒定时，气溶胶产生率近似于钚的氧化率。结果表明，该速率强烈依赖于空位产生和消耗的空位扩散率和反应速率常数。298 K 温度下的气溶胶生成速率约为 108 个粒子/cm2/s。
