Company Develops Solution That Revolutionizes The Nuclear Sector By Converting Most Of The Waste Into Fuel, Promoting Greater Sustainability In Energy Generation
The management of nuclear waste has been one of the biggest challenges in the energy sector. With the increasing demand for nuclear energy, the need for efficient and sustainable solutions to deal with this waste becomes increasingly urgent.
However, a new technology promises to revolutionize this scenario by transforming nuclear waste into valuable energy assets and helping to create a more sustainable future.
Moltex Energy Canada Inc. has developed a process called WATSS (Waste to Stable Salt), which can recycle up to 90% of nuclear waste, transforming it into high-energy fuel.

It supports up to 1 ton, delivers 1008Wh, and keeps your refrigerator running for 7 hours in case of a power outage: the DJI Power 1000 Mini arrives as an almost indestructible portable station for emergencies and off-grid use.
The technology not only significantly reduces the volume of waste but also converts it into a clean energy source, contributing to the economy and environmental preservation.
The Challenge Of Nuclear Waste
Traditionally, used nuclear fuel has been regarded as a problem due to the high cost and complexity of its storage and disposal. Proper management of this waste is vital, especially as the use of nuclear energy expands globally.
This creates a paradox: although nuclear energy is seen as a clean energy solution, the management of its waste remains a critical challenge.
The WATSS emerges as a response to this dilemma. Moltex’s technology can transform used nuclear fuel into a reusable energy resource, solving two problems at once: safe disposal and clean energy generation.
How WATSS Works
The WATSS process is an innovative and structured approach, composed of several steps that allow the transformation of nuclear waste into high-energy fuel.
The process begins with the pre-treatment of used fuel, which is transported to a WATSS facility and undergoes initial preparation.
Initial Preparation:
- The used fuel is transported to a WATSS unit (preferably located near nuclear power plants to reduce transport risks) and undergoes an oxidation-reduction process for transformation.
First Phase:
- Transuranic elements are extracted from uranium by dissolving them in molten salt, while uranium remains insoluble.
Subsequent Phases:
- The extracted transuranic elements are processed into molten salt fuel, eliminating fission products.
- The final salt mixture is adjusted according to the reactor’s needs, generating chloride or fluoride-based salts.
According to Rory O’Sullivan, CEO of Moltex, “The increasing demand for nuclear energy must be accompanied by advanced fuel cycle solutions. WATSS is a transformative solution that not only reduces environmental impacts but also creates value by turning waste into an energy asset.”
Economic And Environmental Benefits
The WATSS technology offers significant benefits, both from an economic and environmental perspective. By transforming nuclear waste into fuel, it creates an opportunity to utilize this waste rather than treating it as a long-term liability. This can result in specific savings for energy companies and waste owners.
With more than 60 nuclear reactors under construction and over 80 small modular reactor (SMR) projects underway around the world, WATSS positions itself as a viable and scalable solution.
Moltex also offers consulting services to help nuclear waste owners reduce their risks and adopt a circular economy model, promoting the transition to cleaner and more sustainable energy production.
