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%.
