ANS certificate and certification courses continue to improve
The American Nuclear Society launched its inaugural Nuclear 101 certificate course at the 2024 ANS Winter Conference and Expo in November. The five-day program, which is designed to provide participants with a robust understanding of nuclear energy and engineering, was the talk of the conference, with nearly 50 attendees from different nuclear organizations participating in the course.
