World Nuclear Energy Day 2025 – Australia December 2nd – Webinar

Once again, Innovate Australia proudly serves as the official Ambassador for World Nuclear Energy Day in 2025. For the fifth consecutive year, they invite you to celebrate the remarkable advancements in technology and innovation within the global nuclear energy sector.

This year’s theme, “We are critical mass!” highlights the collective impact and support needed to drive nuclear energy forward as a crucial part of our clean energy future. December 2nd holds profound significance, honouring the groundbreaking achievement of the first self-sustaining chain reaction and the launch of the world’s first commercial-scale electric power reactor. On this day in 1942, Enrico Fermi’s Chicago Pile-1 reactor made history with a self-sustaining chain reaction. Exactly 15 years later, on December 2, 1957, the first commercial reactor in Shippingport, Pennsylvania, reached criticality.

As Australia intensifies its pursuit of zero emissions, nuclear energy continues to gather support and recognition as a vital, clean, and reliable power source. Join in acknowledging this incredible legacy and exploring nuclear energy’s promise as we look to the future.
