Abstract

The results have been presented of radiochemical analysis of 8 samples of nuclear fuel irradiated in a VVER-440 reactor. The procedures have been described for the radiochemical separation and analysis of nuclides of uranium, plutonium, americium, curium, neodymium, cesium, cerium, samarium, europium, gadolinium, neptunium using radiochemical and instrumental techniques, including ion exchange chromatography, alpha, gamma, and mass spectrometry. The data on isotopic composition, mass content of nuclides, and fuel burnup, calculated by the method of heavy atoms and by accumulation of burnup monitors ^145+146Nd, ¹⁴⁸Nd, have been reported.

VVER-440反应堆乏核燃料的放射化学分析

摘要

已经对在VVER-440反应堆中辐照过的8个核燃料样品进行了放射化学分析，给出了结果。已描述了使用放射化学和仪器技术（包括离子交换色谱法，α，γ、,、,、,、,、,、 the，和质谱。据报道，通过重原子法和燃耗监测仪^{145 + 146} Nd，¹⁴⁸ Nd的积累计算出的同位素组成，核素质量含量和燃耗数据。
