Abstract

The invention discloses a method for measuring uranium content in uranium hexafluoride hydrolyzate. The method mainly includes: preparation of uranium standard solution; instrument debugging, software setting, and optimization of working parameters; working curve, analysis limit, and measurement range of uranium Determination; determination and other steps. The analysis is comparable to the GRAV method in precision, high accuracy, stable method, simple and fast, and short time-consuming. It takes less than 1 minute to measure a sample, and hundreds of samples can be processed at one time in one working day. It is suitable for large-scale UF6 hydrolysis. Determination of uranium content in liquid samples.

Description

A method for measuring uranium content in uranium hexafluoride hydrolyzate Technical field The invention belongs to a kind of method for measuring uranium content, be specifically related to a kind of method for measuring uranium content in uranium hexafluoride hydrolyzate Methods. Background technique Uranium hexafluoride (UF6 purity ≥ 99.5%) is one of the most important compounds in the nuclear fuel cycle, for making uranium isotopic In order to ensure the safe, stable and economical operation of the main process operation equipment of the element separation plant, the quality control and monitoring of the feed and concentrated products must be carried out. Quick check. The main control indicators of uranium hexafluoride include abundance, purity and impurities. Accurate determination of uranium hexafluoride content will Provide sampling and calculation basis for the measurement of 36 kinds of impurities such as boron. The assay method of uranium content in urani...
