Multi-Nuclide Adsorption

Blue Magnet develops NuMagneto, an eco-friendly adsorption-based solution for radioactive liquid waste treatment.
NuMagneto is designed to selectively capture multiple radionuclides, including Cs, Co, and Sr, using a single magnetic nanoparticle-based adsorbent.
The technology enables smart re-collection through magnetism, helping reduce secondary radioactive waste and treatment cost.
Blue Magnet also develops NuMagnetoSYS, a compact modular and AI-based unmanned automated acquisition system for safer nuclear waste treatment.

(1) Problem Definition / Development Background

Existing radioactive liquid waste treatment methods rely heavily on ion exchange resins and evaporation.
Traditional ion exchange resins cannot effectively distinguish radionuclides from normal ions, causing early saturation.
This leads to large volumes of secondary waste, high disposal cost, storage burden, and regulatory pressure.
SMRs and floating nuclear power plants may generate highly concentrated radionuclide wastewater, requiring compact and efficient treatment solutions

(2) Value Proposition / Solution

NuMagneto captures multiple radionuclides with one magnetic adsorbent.
The material can be re-collected by magnetism, reducing secondary waste and improving treatment efficiency.
The solution can potentially reduce radioactivity in nuclear wastewater by 70–95%.
Blue Magnet aims to cut waste disposal costs by tens to hundreds of times while improving nuclear safety and environmental protection.

(1) PoC Progress

Blue Magnet is planning overseas PoC validation in Europe and the Eastern United States.
The company identifies Europe as the top PoC region due to simultaneous demand from nuclear decommissioning, operating plants, SMRs, and EU taxonomy requirements.
Planned verification includes nuclide removal efficiency, adsorption performance, environmental regulation review, and research institution-based technology validation.

(2) Global Expansion

Target European regions include Czech Republic, Finland, France, Poland, Sweden, and the United Kingdom.
Target U.S. regions include Virginia, New England, and Pennsylvania.
Blue Magnet plans a 3-year overseas demonstration roadmap:
- 2026: Overseas performance verification and partner search.
- 2027: Demonstration design and system fabrication.
- 2028: Demonstration implementation and commercialization.
Commercialization goals include PoC data access, utility or EPC partnership, EU standard solution registration, and expansion across European member states.
