Abstract

The present work shows experimental data on the release of some radionuclides that are forming the so-called ε particles in the spent nuclear fuel (SNF): Mo, Tc, Ru and Rh. The leaching experiments were carried out with a 60 GWd·t−1 burnup SNF at two different pH values, 8.4 and 13.2, and under oxidizing conditions. The modelling of the data showed that the higher release of Mo, Tc, Ru and Rh at pH 13.2 could be due to the higher dissolution rate of the ε-particles. Graphical abstract

高燃耗乏核燃料中 Mo、Tc、Ru 和 Rh 在碱性和超碱性 pH 值下的释放模拟

本研究显示了在乏核燃料（SNF）中形成所谓ε粒子的一些放射性核素的释放实验数据：Mo、Tc、Ru 和 Rh。沥滤实验是在两种不同的 pH 值（8.4 和 13.2）和氧化条件下，使用 60 GWd-t-1 燃烧当量的乏核燃料进行的。数据建模表明，pH 值为 13.2 时，钼、锝、钌和铑的释放量较高，这可能是由于ε粒子的溶解速率较高所致。图表摘要
