Transmutex
Recycles nuclear waste to create carbon-free nuclear energy
About Transmutex
Transmutex is a pioneering startup that aims to revolutionize the civilian nuclear energy sector. The company's innovative technology focuses on producing nuclear energy that is not only safer and less expensive but also non-proliferant. This is achieved through a unique process that combines a particle accelerator with a nuclear fuel assembly to create a non-self-sustaining reaction. This reaction can be halted in less than 2 milliseconds, ensuring a high level of safety.
Transmutex's technology is highly adaptable, capable of using various fuels, including thorium, a metal as common as lead. This flexibility helps in addressing the world's increasing demand for carbon-free energy. The company has developed a range of hardware and software products that leverage this technology to provide carbon-free base load power, addressing the core issues of safety, cost, and proliferation risk that have traditionally hindered the global deployment of nuclear energy.
The company's subcritical systems can generate between 220 MWe to over 1 GWe of power with modular installations. Furthermore, their technology can be used to destroy radioactive waste. By using thorium fuel, the system does not generate plutonium waste and can even be used to burn long-lived radioactive waste from uranium-based nuclear energy.
Transmutex also offers high-energy physics simulation software for designing energy production systems, radioisotope production, radioprotection, and more. Their particle accelerator can produce radioisotopes for various applications, including medical imaging, cancer therapies, radiography, and food irradiation.
The startup has attracted investment from leading global venture capitalists and private investors, indicating strong confidence in its business model and future prospects.
