Shares of NuScale Power Corp. (NYSE: SMR) climbed nearly 3% in overnight trading ahead of Wednesday, building on a positive close as investor enthusiasm for nuclear energy stocks continues to grow amid the artificial intelligence boom.
The company announced two new additions to its Board of Directors, including a former chairman of the U.S. Nuclear Regulatory Commission, following their election at NuScale’s Annual Meeting of Stockholders on May 29.
Dale E. Klein, one of the two new directors, is Professor Emeritus in Engineering at The University of Texas at Austin and brings more than 40 years of technical expertise and nuclear industry experience.
Klein previously served as chairman of the U.S. Nuclear Regulatory Commission and as Assistant to the Secretary of Defense for Nuclear, Chemical and Biological Defense Programs, and currently serves on nuclear oversight and advisory committees in the United Arab Emirates and Japan.
The second new board member, Stuart A. Harshaw, serves as President and CEO of Nickel Creek Platinum Corp., a Canadian mining exploration and development company, as well as President of Stuart Harshaw Consulting.
Harshaw brings more than 35 years of leadership experience in the mining industry, including extensive expertise in engineering, procurement, and construction models, according to the company.
NuScale’s board now comprises nine directors, eight of whom are independent, following the two new additions.
NuScale designs and develops advanced Small Modular Reactor nuclear power technology and is the only company to have received design certification from the U.S. Nuclear Regulatory Commission for its SMR.
Reports that South Korea is considering a possible investment in NuScale’s SMR program in Tennessee, as part of a $200 billion investment commitment to the U.S., have added fresh optimism to the stock’s outlook.
South Korea is also reportedly exploring NuScale’s technology for a proposed SMR project in Uljin, further broadening the company’s potential international footprint.
On Stocktwits, retail sentiment around SMR stock improved from “bullish” to “extremely bullish” territory over the past 24 hours, amid high message volumes from the platform’s community.
One bullish user commented, “South Korea has a strong reason to work with NuScale. Companies like Doosan Enerbility and Samsung C&T are already involved in the nuclear industry and could benefit from supplying equipment and construction services. Since South Korea would be investing in a U.S. project while also creating business opportunities for its own companies, a partnership could make strategic sense for both sides.”
SMR stock has declined more than 14% so far in 2026, but has posted three consecutive weeks of gains, adding more than 10% in June alone.
