370 Billion Disappeared in a Day… What Happened to the 'Next-Gen Nuclear Stocks'?

NuScale Power Corporation (NASDAQ: SMR) closed the most recent session on the New York Stock Exchange at $16.53, down 5.72%. Its market capitalization stands at about $4.67 billion—roughly ₩6.8 trillion—with nearly $250 million (around ₩370 billion) erased in a single day.

Earlier this month, The Motley Fool pointed out that NuScale’s share price has plunged more than 60 percent from last year’s high and warned of additional overhang risk as majority owner Fluor plans to divest its remaining stake by the end of the second quarter. Around the same time, Bank of America cautioned that volatility could persist despite a recent surge, yet upgraded its rating on the stock from Underperform to Neutral—an indication that high risk and growth potential coexist.

NuScale is the only small modular reactor (SMR) technology company to have secured U.S. Nuclear Regulatory Commission (NRC) design approvals for both its 50 MW and 77 MW reactors. Its scalable design allows up to 12 modules to be combined for a total output of 924 MW. Through an exclusive partnership with ENTRA1 Energy, NuScale is advancing projects in Romania and elsewhere, aiming for commercial operation by 2030. However, its current revenue base is modest, and the substantial costs of large-scale construction plus potential permitting delays remain key sources of share-price volatility.
