FOR IMMEDIATE RELEASE
Saint John, NB – June 2025
At Canada’s leading technical nuclear conference this week, Moltex Energy proudly unveiled major breakthroughs that could redefine how nuclear waste is handled — turning used fuel into a valuable resource while sharply reducing the volume of long-term waste.
Key Announcements from Moltex Energy Canada at the Canadian Nuclear Society Conference
Recycling Used Fuel
CEO Rory O’Sullivan delivered a plenary presentation on the exciting progress of Moltex’s Waste-to-Stable-Salt (WATSS) process, highlighting the growing economic and environmental value of used nuclear fuel.
Based on current stockpiles in North America alone, there is:
- $80 billion in fuel value from transuranic elements
- $60 billion in residual uranium
- $30 billion in rare earth elements
“This is a game-changer for the sustainability of nuclear energy,” said O’Sullivan.
“We’re showing that nuclear power can be not only carbon-free but resource-smart — turning yesterday’s waste into tomorrow’s clean energy. It is no longer acceptable to bury such a valuable resource.”
Validated by First-of-Its-Kind Testing
Lead chemist Jose P. Zuniga shared groundbreaking results from real-world testing on used CANDU reactor fuel, conducted in collaboration with Canadian Nuclear Laboratories:
- Successfully extracted over 77% of the transuranics from real used fuel — a major scientific and commercial milestone
- New testing shows over 95% extraction, to be presented at the
ANS Advances in Nuclear Fuel Management Conference,
July 20–23, 2025, Clearwater, Florida
Reducing Long-Term Nuclear Waste
Chief Technology Officer Olivier Grégoire described how the WATSS process can reduce the footprint of long-term nuclear waste repositories by as much as 80%. The process enables:
- Advanced borehole disposal technologies
- Reduced surface dose levels
- Significantly lower waste storage requirements
These innovations offer more compact, flexible, and cost-effective disposal solutions.
Engaging with Global Experts
Moltex also participated in the Plenary Session on Advances in Reactor Technologies, where the team discussed how next-generation fuel recycling can integrate with modern reactor designs.
Acknowledging the Nuclear Community
Moltex Energy Canada expressed its sincere appreciation to the Canadian Nuclear Society for providing a global platform to share these critical advancements in nuclear science and technology.
