## Investments

| Company | Description | Amount | Stage | Date | Website |
| --- | --- | --- | --- | --- | --- |
| Alva Energy | Alva Energy specializes in nuclear plant upgrades called "uprates" to boost clean power output from existing U.S. reactors. It standardizes complex retrofits into repeatable, turnkey projects for faster and cheaper deployment. | $33M | Series A | Feb 12, 2026 |  |
| Studsvik | Studsvik offers a range of advanced technical services to the international nuclear power industry. |  | Post-IPO Secondary | Jan 08, 2026 |  |
| X-energy | X-Energy is a nuclear reactor and fuel design engineering company that develops Generation IV, high-temperature gas-cooled small modular reactors (SMRs) together with proprietary TRISO-X particle fuel. Their flagship reactor, the Xe-100, delivers about 80 MWe per unit and can be scaled in modular “packs” to reach higher output. X-Energy also buildsits own TRISO-X fuel to maintain supply control and quality. In addition, the company operates a plant support center to provide fleet monitoring, maintenance planning, training, and diagnostics for its reactor customers. | $700M | Series D | Nov 24, 2025 |  |
| General Fusion | General Fusion pursues a commercially oriented path toward fusion energy by developing a magnetized target fusion (MTF) technology. The company applies advances in plasma physics, modern electronics, materials, and compression mechanisms to generate fusion-relevant conditions. It operates a demonstration system, Lawson Machine 26 (LM26), thatinjects magnetized plasma into a liquid metal liner and compresses it using coordinated mechanical pistons to reach high temperatures and pressures. The technology serves as a practical stepping stone toward building a fusion demonstration facility and ultimately delivering fusion-derived electricity to the grid. The approach focuses on closing the gap between demonstration milestones and a deployable power-plant system. | $21.6M | Venture - Series Unknown | Aug 21, 2025 |  |
| Deep Isolation | Nuclear power contributes over 10% of the world’s power needs. From the 500 reactors built around the world, the growing inventory of nuclear waste is over 450,000 metric tons and is increasing by ~12,000 tons each year. In the US, there is currently ~$40 Billion in the Nuclear Waste Fund, with no active program to dispose of the 80,000 tons ofnuclear waste. Many countries are actively seeking new options as no country anywhere in the world has ever disposed of high-level waste or spent nuclear fuel. A new approach is needed.Nuclear waste disposal is a $500 billion worldwide market.Deep Isolation is the first private company to offer a solution to dispose of nuclear waste in safe, permanent deep geologic repositories. A solution that is proven, demonstrated and primed to disrupt and dominate in this untapped market. Deep Isolation combines scientific and nuclear expertise with sophisticated stakeholder engagement skills to work alongside communities to design and deliver an equitable and environmentally protective solution. | $33M |  | Jul 23, 2025 |  |
