Keyword 43：Advanced Large-scale Uranium Purification and Conversion Bases

China has established two uranium purification and conversion bases in northern and southern China respectively. Using the integrated process of uranium purification and conversion, the two bases have formed a 10,000-ton uranium purification and conversion capacity through the development and application of key equipment such as pulsed extraction columns, fluidized beds and new fluorination reactors. The automated control of the production lines has been improved through digital technology systems. Thanks to the material recycling technology, the volume of waste generated has been cut down from the source, which has made the production lines much safer and more eco-friendly. Overall, the purification and conversion process is now advanced by international standards.
