This series of articles, "On The Yellowcake Trail," tracks the history of all aspects of uranium in Canada from the mining and milling, to processing and use, throughout its eighty-year history. The series began with the history of uranium mining in Canada. This article examines the various stages involved in processing uranium and the issues that emerge with each of these stages.
The nuclear industry paints a rosy picture of its operations, portraying itself as a well-planned, controlled and safe industry, and the answer to climate change. But the track record of flooding and spills at mine sites, cost overruns, delays, leaks and shutdowns at nuclear plants, and the catastrophic nuclear "accidents" at Chernobyl and Three-Mile Island, are in stark contrast with that positive image. At every stage in the nuclear chain, from extraction to processing and use, vast amounts of radioactive waste and other highly hazardous wastes are produced. Spills and leaks commonly occur, marking treacherous places in the yellowcake trail that remain deadly for hundreds of thousands of years.
