Reflections on NOW

Last month, I talked about my goal of strengthening ANS’s voice, in part by attending three conferences. I have now checked the first event off that list: the Nuclear Opportunities Workshop.

This year, NOW took another step in outgrowing its “workshop” moniker and transitioning to a full-fledged regional conference and expo. What started only a few years ago as a small gathering in Oak Ridge, Tenn., with roughly 50 attendees has skyrocketed to an event with 1,100 people in attendance in Knoxville.

NOW’s popularity reflected how busy the roughly 350 nuclear companies in Tennessee have been in recent years. There is significant work going on surrounding Gen IV reactor development and deployment, advancements in new nuclear fuels, and defense-related builds like the Uranium Processing Facility.

From remediation to renaissance: Our nuclear future begins with cleanup

ANS Executive Director/CEO Craig Piercy’s reflection on the 80th anniversary of the Trinity Test (Nuclear Newswire, July 16) was a thoughtful and fitting remembrance of the achievements and legacy of the World War II generation of nuclear pioneers. We also see legacy environmental cleanup as a vital next step as our industry launches what Secretary of Energy Chris Wright has defined as “Manhattan Project 2.0.”

Work advances on X-energy’s TRISO fuel fabrication facility
