Abstract

Electrolytic enrichment is used as a method for measuring tritium in environmental waters. All measurement data and parameters are collected in control charts. Together with measurements and modelling of temperatures in the electrolytic cooling system, these charts were used to optimise the entire process. After modification, the scatter of the final sample masses was considerably reduced. Enrichment factor scatter was reduced by 33%, and overall enrichment can now be increased by up to 64%.

摘要

电解浓缩法被用作测量环境水中氚的方法。所有的测量数据和参数都被收集在控制图中。结合对电解冷却系统中温度的测量和建模，这些图表被用于优化整个过程。经过改进，最终样品质量的离散度大大降低。浓缩因子的离散度降低了 33%，并且整体浓缩现在可以提高多达 64%。
