本文件规定了通过傅里叶变换红外光谱（FTIR）测定重水同位素纯度的分析方法。适用于整个重水浓度范围的测定。该方法适用于重水反应堆发电厂或任何其他相关领域中工艺系统不同步骤的工艺控制。 该方法可用于重水反应堆发电厂或研究反应堆、重水生产厂和重水相关区域的重水同位素纯度测量。

This document specifies an analytical method for determining heavy water isotopic purity by Fourier transform infrared spectroscopy (FTIR). It is applicable to the determination of the whole range of heavy water concentration. The method is devoted to process controls at the different steps of the process systems in heavy water reactor power plant or any other related areas. The method can be applied for heavy water isotopic purity measurements in a heavy water reactor power plant or research reactor, heavy water production factory and heavy water related areas.
