- NuScale finished Tuesday at $13.95, gaining 8.22%. Volume was close to 60 million shares.
- NuScale Power named Stuart Harshaw and Dale Klein, a former chairman of the U.S. Nuclear Regulatory Commission, to its board after the annual meeting on Friday.
- The NYSE plans to run its normal session from 9:30 a.m. to 4:00 p.m. ET, and June 3 isn’t shown as a 2026 holiday on the exchange.
NuScale Power is coming into Wednesday’s session following an 8.2% gain. The stock keeps moving more on speculation around small nuclear reactors and rising power demand from industry and data centers than on present-day revenue.
The Corvallis, Oregon-based company ended Tuesday’s session at $13.95. That’s up from $12.89 at Monday’s close. The stock moved between $12.51 and $14.30 during the session, with volume coming in just under 60 million shares, according to Yahoo Finance historical data.
Why it matters now: NuScale is one of the only listed U.S. companies focused solely on small modular reactors, or SMRs—these are smaller nuclear reactors built in modules and meant for power projects. Shares moved as the company added board members with more experience in regulation and project work. Investors are still waiting to see if NuScale’s project pipeline leads to signed and funded deals.
NuScale said it added Stuart A. Harshaw and Dr. Dale E. Klein to its board after the annual meeting on May 29. The company now lists nine directors, with eight counted as independent.
Harshaw runs Nickel Creek Platinum Corp. and brings over 35 years in mining and industry projects. Klein, professor emeritus at the University of Texas at Austin and former chair of the U.S. Nuclear Regulatory Commission, has more than 40 years of experience in nuclear and technical positions, NuScale said.
NuScale Chief Executive John Hopkins said in the company’s statement that “Dr. Klein’s decades of leadership” and Harshaw’s experience with projects will “provide tremendous value.” NuScale Power
Shareholders backed all nine board nominees, signed off on executive pay in a non-binding vote and ratified Ernst & Young as auditor for 2026, according to a separate SEC filing. CEO Harshaw and Kimberly Warnica each saw significantly more withheld votes than others on the slate, which the filing notes as a minor governance snag but not enough to stop their election.
The board news comes as NuScale faces pressure to turn interest into sales. Revenue dropped to $565,000 in the first quarter, down from $13.4 million the year before. The company closed March with $1.0 billion in cash, cash equivalents and investments.
NuScale says talks with ENTRA1 and the Tennessee Valley Authority are moving closer to a power purchase agreement, or PPA, where a buyer locks in to buy electricity from a project. The company also referenced its RoPower project in Romania. Management said that deal needs financing to move into its next stage.
Oklo and BWX Technologies are still in the race. Both outfits are in the advanced nuclear space, but NuScale leans on its edge with U.S. regulators. The company pitches its NuScale Power Module as able to put out 77 megawatts, expandable to 924 megawatts if all 12 units run together.
NuScale says stronger governance and enough cash on hand are no guarantee of customers, financing or building. The company points to risk from contracts, partner funding, manufacturing problems, tougher competition, the price of power and wild swings in its stock. Those could all push real results away from the plans, NuScale lists in its filings.
NuScale shares are getting another bump, but the company is still working to land real, financeable reactor deals. For now, the stock is trading on hopes and headlines.
