U.S. Small Modular Reactor Stocks Surge by $450 Million in a Day: Is the Rebound Starting?

NuScale Power Corporation (NYSE: SMR) closed at $10.70 on the New York Stock Exchange, up 8.19% from the previous day. Trading volume exceeded 18.05 million shares, and market capitalization climbed by roughly $330 million—to about $3.7 billion (approximately KRW 5 trillion)—in a single session.

Despite the recent rally, the stock still trades roughly 75% below its all-time high. Analysts say that while NuScale has growth prospects over the next three years, its share price remains highly volatile. Uncertainty persists around the stock after major shareholder Fluor sold about $160 million worth of shares and a class-action lawsuit was filed against NuScale.

NuScale is the only U.S. company to receive design certification from the Nuclear Regulatory Commission for small modular reactor (SMR) technology. It is developing its VOYGR power plant concept, which pairs multiple 77-megawatt modules. The company is also pursuing up to 6 gigawatts of SMR deployment with the Tennessee Valley Authority and advancing international projects in countries such as Romania. However, with no reactors yet in commercial operation, questions remain about when NuScale will begin generating meaningful revenue.
