Small Modular Reactor Stocks Surge by 550 Billion Won in a Day, Powering AI Data Centers

NuScale Power (SMR) soared 6.93% to close at $20.22 (approximately KRW 26,000) on the New York Stock Exchange in the last trading day. Its market capitalization swelled to about $5.7 billion (mid-KRW 7 trillion), adding roughly $426 million (KRW 550 billion) in a single session. Trading volume climbed to 19.14 million shares, reflecting robust investor demand.

Earlier this month, Duke Energy named NuScale’s VOYGR small modular reactor as a leading candidate for its North Carolina plant site, while the U.S. administration pushed for SMR adoption at military bases and Department of Energy facilities—moves that drove the stock up as much as 17% intraday.

NuScale is working exclusively with partner ENTRA1 and the Tennessee Valley Authority (TVA) on a carbon-zero power project of up to 6 GW. Market expectations are also rising for a major contract to supply 24 reactors for AI data centers.

Founded in 2007 and based in Oregon, NuScale was the first company to receive U.S. Nuclear Regulatory Commission (NRC) design certification for a small modular reactor. After securing approval for its initial 50 MW module and later for a 77 MW design, the firm has emerged as a next-generation baseload power provider. However, still in the pre-commercial stage, NuScale remains unprofitable, and there are concerns that parent company Fluor’s planned share sale could increase future stock volatility.
