The US nuclear industry had its "best year ever" in 2019, as it "led the world" in generating more than 809 terawatt hours of electricity, Rita Baranwal, assistant secretary for nuclear energy at the Department of Energy, said yesterday. Despite this achievement, the country's ability to produce domestic nuclear fuel is "on the verge of a collapse", she added.

Urenco's uranium enrichment plant being built in New Mexico eyes expansion to double capacity A uranium enrichment plant in southeastern New Mexico is eyeing a third expansion that would double the $3 billion plant's capacity. But the president and chief executive officer of Urenco USA, Gregory Smith, says it's not a done deal.
The uranium oxide is then recovered from the solution as in a conventional mill. A conversion plant removes impurities from yellowcake and chemically converts the material to uranium hexafluoride. This is heated to become a gas and then loaded into cylinders, where it cools and condenses into a solid.
