Research on the current status and development direction of Japan's nuclear contamination water treatment technology based on patent analysis

Key Points

• Japanese patent applications for nuclear water treatment increased significantly after the Fukushima incident, highlighting a surge in innovation.
• Adsorption techniques emerged as the primary treatment method, with a focus on materials like silicates and titanates for effective cesium removal.
• Research and development are predominantly led by Tokyo Electric Power Company, which emphasizes adsorption without exploring alternative methods.
• Future work should focus on optimizing adsorption processes and studying environmental impacts of treated nuclear water disposal.
