About
Lead accel Co., Ltd. is a Japanese deep-tech startup developing a compact and economically viable Accelerator Driven System (ADS) for nuclear waste transmutation, based on liquid metal technology pioneered at the Tokyo Institute of Science. Founded on August 8, 2025 and recognized as a Tokyo Institute of Science Certified Venture (No. 20) on October 21, 2025, the company's mission is to reduce the volume and hazardous lifetime of high-level radioactive waste generated by nuclear power plants worldwide. The ADS approach uses proton beam acceleration to irradiate a liquid heavy metal target, generating spallation neutrons that drive the transmutation of minor actinides such as Neptunium-237 (half-life 2.14 million years) into stable isotopes or fissionable fuel.
