Nuclear power is back in focus as electricity demand climbs from data centers, EVs, and air conditioning. This October 2026 roundup from Simply Wall St looks at three nuclear-focused companies: NuScale Power, Constellation Energy, and Oklo. Each offers a different angle on low-carbon power, from small modular reactors to large existing nuclear fleets. Constellation Energy looks the most established, with roughly 920 MW of long-term nuclear contracts with investment-grade buyers and an average term of 18.5 years. NuScale is working on SMR deployment through projects like Romania's RoPower, while Oklo recently cleared a regulatory step with NRC approval of its Principal Design Criteria for the Aurora reactor. The article notes that Oklo is not fully licensed yet. For anyone tracking nuclear's role in grid decarbonization, the piece is a useful starting point, though it is general commentary and not financial advice. The main open question is whether SMRs can move from design to construction at scale.
