Which companies are developing advanced nuclear technologies?

Several companies are developing advanced nuclear technologies, including:

1. **Oklo**: A startup backed by OpenAI CEO Sam Altman, Oklo is developing micro nuclear reactors and has plans to build a commercial fuel fabrication facility. Their Aurora nuclear power plant is a small fast neutron fission reactor that can produce up to 15 MW of power and operate for 10 years or longer before refueling.
2. **Lightbridge**: Based in Massachusetts, Lightbridge is developing proprietary next-generation nuclear fuel technology for existing light-water reactors and pressurized heavy water reactors. They are also developing fuel for next-generation small modular reactors.
3. **Nano Nuclear Energy**: This advanced technology-driven nuclear energy company is developing cutting-edge portable and microreactor technologies, nuclear fuel fabrication, transportation, and consulting services. Their reactor products in development include ZEUS, a solid core battery reactor, and ODIN, a low-pressure coolant reactor, each representing advanced developments in clean energy solutions.
4. **Centrus Energy**: This company is producing high-assay, low-enriched uranium (HALEU) under a demonstration project and has partnered with Oklo to explore developing a comprehensive HALEU fuel cycle.

These companies are at the forefront of nuclear technology development, pushing the boundaries of what is possible with nuclear energy and working to make it safer, more efficient, and more sustainable.
