Nuscale Stock news
On September 16, 2026, the U.S. Nuclear Regulatory Commission (NRC) issued a final Safety Evaluation Report (SER) for the emergency core cooling system (ECCS) of NuScale Power's (NYSE: SMR) 77 MWe VOYGR--6 reactor design. This regulatory milestone confirms the technical adequacy of the reactor's passive safety features and represents a critical step toward the issuance of the Standard Design Approval (SDA). The completion of this review phase is a primary indicator of the "technological and regulatory maturity" of the uprated VOYGR design, significantly de--risking the project for domestic utilities. Following the announcement, SMR shares experienced a 5.5% increase, reflecting improved investor confidence in the 2028 deployment timeline.
