X-energy Secures $700M for Advanced Nuclear Reactors
November 29, 2025, 3:32 pm
X-energy, a nuclear startup, raised $700M in Series D funding. This boosts its total funding to $1.8B. The funding will scale production of Xe-100 reactors and TRISO-X fuel. These reactors are safer and more efficient. They offer a clean energy alternative.
X-energy, a nuclear energy startup, has secured $700 million in a Series D funding round. This significant investment highlights growing interest in advanced nuclear technologies. The company plans to use the funds to scale its operations. Its focus is on the Xe-100 reactor and TRISO-X fuel production.
The Series D round was led by Jane Street. Other participants included Ares Management funds, ARK Invest, and Emerson Collective. The diverse group of investors signals confidence in X-energy's technology. This financing brings X-energy's total funding to $1.8 billion.
X-energy specializes in high-temperature, gas-cooled Small Modular Reactors (SMRs). The Xe-100 model is a key product. It can generate 80 megawatts of electricity. Its design incorporates several innovative safety features.
The Xe-100 uses TRISO-X fuel. This fuel consists of uranium particles encased in carbon-coated pebbles. Helium gas flows over these pebbles within the reactor. This process collects heat to generate electricity. TRISO-X fuel is designed for safety. Multiple layers protect against the release of fission byproducts. The fuel can withstand extremely high temperatures. This design minimizes the risk of meltdowns.
X-energy emphasizes the safety features of its reactor. Only four components require active management by staff. This reduces the potential for human error. The reactor can operate continuously for up to two decades. Each Xe-100 contains 200,000 TRISO-X fuel spheres.
X-energy is building a TRISO-X fuel manufacturing plant in Oak Ridge, Tennessee. This facility is crucial for securing its fuel supply. The new funding will expand the company's supply chain. This will ensure reliable project delivery.
X-energy is collaborating with major companies. A partnership with Amazon involves building a nuclear power plant in Washington state. The facility will initially host four Xe-100 reactors. This is expected to generate 320 megawatts of power. The long-term goal is to deploy over 5 gigawatts of power by 2039.
Another collaboration is with Dow Inc. They plan to build a four-reactor power plant at Dow's Texas manufacturing campus. This facility is expected to be operational in the early 2030s.
X-energy reports a sales pipeline of 144 reactors. This represents over 11 gigawatts of power generation capacity. The company aims to establish new partnerships. It seeks to accelerate the commercialization of its technology.
SMRs offer several advantages over traditional nuclear power plants. They are smaller and more flexible. They can be deployed in a wider range of locations. Their modular design allows for easier construction and scalability. SMRs can provide a reliable source of clean energy. They can help reduce reliance on fossil fuels.
Nuclear energy is increasingly recognized as a key component of a clean energy future. It provides a low-carbon alternative to fossil fuels. Advanced reactor designs like the Xe-100 enhance safety and efficiency. This helps to address concerns about nuclear power.
The $700 million funding round is a major milestone for X-energy. It enables the company to advance its technology and expand its reach. X-energy is poised to play a significant role in the future of nuclear energy. Its innovative reactors and fuel designs offer a promising path toward a cleaner, more sustainable energy future. The company's focus on safety and reliability is crucial for building public trust in nuclear power. The partnerships with Amazon and Dow demonstrate the growing interest in nuclear energy from major corporations. X-energy's success could pave the way for wider adoption of advanced nuclear technologies.
