Only SMR design certified by the US NRC; light-water modules.
Holtec scrapped its Nasdaq listing on September 16, days before pricing 50 million shares at $15–18. CEO Kris Singh blamed the market's turn against the AI data-centre trade: "Our business, rightly or wrongly, is viewed as connected to it." In the same week the NRC granted an exemption letting Holtec start early site work on two SMR-300 units at Palisades.
Four SMR units operate worldwide, all in Russia and China, and that count has not moved since 2023 — even as 2026 brought a construction permit, a modern licensing framework and four reactors reaching criticality in the US. A read of the gap between permits and power.
The NRC proposed a sweeping rule updating licensing, safety oversight and siting across a plant's whole lifecycle — risk-informed alternatives, performance-based emergency planning for all reactor types, longer license renewals. 45-day comment period.
The U.S. NRC proposed rewriting its licensing framework for advanced nuclear fuel — a regulatory shift bearing on the SMR field broadly.
NuScale Power awarded Paragon (a Mirion company) a contract to complete final design of the Highly Integrated Protection System (HIPS) for its 77 MWe power module — completing the reactor's safety instrumentation architecture.
NuScale Power — NuScale's design became the only SMR certified by the US regulator.
