Nuscale Stock news
On September 1, 2026, NuScale Power (NYSE: SMR) and MillenniTEK announced the successful fabrication of first--of--a--kind boron--oxide pellets for the VOYGR reactor's passive emergency core cooling system (ECCS). This technical milestone is a significant indicator of "technological and manufacturing maturity," as it validates the production processes for a critical safety component within NuScale's specialized supply chain. Despite the achievement, SMR shares experienced downward pressure as investors weighed the milestone against the company's high price--to--sales valuation and the continued anticipation of a definitive Power Purchase Agreement (PPA) with the Tennessee Valley Authority (TVA). Analysts noted that while the ECCS component advances commercial readiness, the market remains focused on the "execution gap" regarding near--term revenue generation.
