Document Type and Number:
WIPO Patent Application WO/2017/188538
Kind Code:
A1
Abstract:
The present invention relates to a method for collecting uranium (U) by a chemical treatment process of a uranium hexafluoride (UF6) cylinder washing waste liquid, and to an apparatus therefor. According to the present invention, by providing a method and an apparatus wherein uranium (U) is separated from a waste liquid generated in a uranium hexafluoride (UF6) cylinder washing process and a filtrate can be released while satisfying atomic energy licensing and environmental standards through evaporation and condensation, an independent technology and process for disposal of a waste liquid generated in a uranium hexafluoride (UF6) cylinder washing process can be secured; more convenient maintenance through the securing of independent technical skills can be attained; and significant cost savings compared with when foreign company facilities are brought in and operated can be attained.
