While small modular reactors (SMRs) are not classified as renewable due to their reliance on uranium, they are designed for clean energy production and can be more cost-effective than traditional nuclear plants. The UN official emphasized the advantages of renewables, highlighting their safety and resilience against geopolitical disruptions."

# Why Oklo and NuScale Power Stocks Took Off Today, 4/30/26

Shares in small modular reactor producers Oklo (OKLO) and NuScale Power (SMR) closed Thursday's trading roughly 11% and 10% higher, respectively. The rally appears to follow comments by the United Nations' climate secretary that the U.S.-Iran war is "supercharging" the push for renewable and clean energy.

Trade SMR with leverage

While SMRs are not generally considered renewable energy, as they rely on finite fuel sources such as uranium, they are designed to provide clean energy. They can be factory-assembled and transported to sites that need power, potentially offering better cost efficiency than conventional large nuclear power plants.

Simon Stiell, the executive secretary of the United Nations Framework Convention on Climate Change, described renewables as being safer, cheaper, and cleaner while speaking at the International Energy Agency in Paris. He described renewables as not vulnerable to chokepoints such as narrow shipping straits or the outcome of geopolitical conflicts.
