Sustainable Nuclear Fuel Recycling Using Molten Salt Reactor Technology

energyPrototypeTRL 3

Imagine if we could treat nuclear waste like a rechargeable battery instead of trash. This project finds a way to recycle spent fuel by melting it into a special salt liquid that burns up the most dangerous leftovers. It turns old waste into new energy and useful medical or industrial materials.

scientific and technological objectives
The business problem

What needed solving

Nuclear power generates spent fuel that is mostly treated as waste, requiring expensive long-term storage. Current recycling methods are limited by the degradation of plutonium isotopes and the buildup of minor actinides.

The solution

What was built

A Reduced-Order-Model of MSR for scenario analysis and synthesized salt mixtures (NaCl-MgCl2-PuCl3 and NaCl-ThCl4-PuCl3) for property characterization.

Who can put this to work

Nuclear Energy
enterprise
Target: Nuclear power plant operator

If you are a plant operator dealing with growing stockpiles of spent nuclear fuel — this project developed a multi-recycling strategy that uses existing infrastructure like the La Hague plant to reduce waste footprints.

Specialty Chemicals
mid-size
Target: Isotope production company

If you are a chemical producer dealing with high costs of rare isotope sourcing — this project developed a method to extract and purify valuable isotopes from molten salt reactors.

Waste Management
enterprise
Target: Nuclear waste disposal service

If you are a waste manager dealing with the high cost of long-term geological storage — this project developed a way to convert plutonium and minor actinides into shorter-lived products, reducing the required repository size.

Frequently asked

Quick answers

What is the estimated cost or price of this technology?

Based on available project data, the project focuses on creating a 'cost/risk optimized' strategy, but specific unit costs or pricing for the technology are not provided.

Is this technology ready for industrial scale?

The project uses existing infrastructure like the Orano plant in La Hague for synergy, but the Chloride MSRs themselves are currently being demonstrated for technical feasibility and performance.

How is the IP and licensing handled?

Based on available project data, there is no specific mention of licensing terms or patent filings in the provided summary.

What is the timeline for deployment?

The research period runs from 2022-06-01 to 2026-05-31, indicating the technology is still in the development and demonstration phase.

How does this integrate with current nuclear plants?

It is designed to be compatible with light-water reactors (LWR) and specifically leverages the existing reprocessing capabilities of the La Hague plant.

Consortium

Who built it

The consortium is heavily industry-weighted with a 53% industry ratio, comprising 8 industrial partners, 4 research centers, and 3 universities. This strong industrial presence, led by Orano Support, suggests the project is closely aligned with practical application and existing infrastructure rather than purely academic research.
