一、前言光谱分析铀同位素的优点是设备简单,操作方便,比常用的质谱分析经济、快速、无记忆效应,直至目前,在核燃料循环中仍用于测定同位素的丰度。考虑到回收料U_3O_8仅需一般中等精度分析其丰度,故开展了铀同位素光谱分析试验。采用ИСП-51型光谱仪,加工了相板记录和光电记录两用暗合,用通常的玻璃感光板 I. INTRODUCTION Spectral Analysis The uranium isotope has the advantages of simple equipment and convenient operation. It is economical, rapid and memoryless than the commonly used mass spectrometry. Until now, it has been used to determine the abundance of isotopes in the nuclear fuel cycle. Taking into account the recovery of material U_3O_8 only moderate general accuracy analysis of its abundance, it conducted a uranium isotope spectral analysis test. Using ИСП-51 spectrometer, processed the phase plate records and photoelectric recording dual-use coincide, with the usual glass plate
