Silex invented and developed the ‘SILEX’ laser isotope separation technology in Sydney during the 1990’s. The uranium enrichment application of the SILEX technology was licensed exclusively in 2006 to Global Laser Enrichment LLC (‘GLE’), a business venture today comprising Silex (51%) and Cameco (49%). Silex and GLE jointly continue to commercialise the technology for potential deployment in the US with the aim of completing a full-scale pilot demonstration by the mid-2020’s.
The first planned commercial plant will involve a tails enrichment facility in Paducah, Kentucky, which will be capable of producing over 5 million pounds of uranium annually for around 30 years – equivalent to a ‘Tier 1’ uranium resource, ranking in the top ten uranium mines by production volume by today’s standards. The Paducah plant has a target commercial operation date in the late 2020’s. There are potentially multiple target markets for the SILEX technology in the global nuclear fuel industry including for natural and enriched uranium, worth several billions of dollars annually.
