In Europe, Studsvik selected GE Vernova Hitachi and Samsung C&T for an initial four-unit BWRX-300 program in Sweden, while Rolls-Royce SMR assigned project-specific turbine work for its first three planned U.K. units and added ABB to its prospective fleet supply chain.
In the United States, defense demand expanded with a planned commercial microreactor at Naval Weapons Station Crane, Centrus signed a binding multi-year HALEU agreement with Radiant, and X-energy’s lead industrial project moved through an NRC advisory-committee review. These developments are not final investment decisions or completed deployments, but they advance the fuel, factory, licensing and customer channels required to turn reactor pipelines into operating assets.
GE Vernova and Samsung: Selected for a four-unit Swedish BWRX-300 program
Studsvik selected GE Vernova Hitachi and Samsung C&T as strategic partners for its ReFirm program. The group will work to develop four BWRX-300 units totaling up to 1.2 GW at either Nyköping or Målma in Valdemarsvik. The sponsor expects the first unit in the mid-2030s.
Why it matters: The agreement adds a European fleet-scale development channel for two SMRFX holdings. Site selection, permitting, financing and a final investment decision remain ahead.
Rolls-Royce: U.K. fleet supply chain becomes more tangible
Rolls-Royce SMR assigned Siemens Energy’s Newcastle facility to manufacture turbine components for the first three planned Gwyndod units. A week later, Rolls-Royce SMR and ABB agreed to explore automation, electrification and communications systems across planned 470-MW units.
Why it matters: The Siemens scope supports repeatable domestic manufacturing, while the ABB agreement broadens the prospective industrial ecosystem. Neither announcement means reactor construction has begun.
Centrus: Binding HALEU agreement adds a microreactor customer
Centrus and Radiant signed a definitive multi-year contract for U.S.-origin HALEU supporting multiple Kaleidos microreactors. Deliveries are expected before decade-end, with customer prepayments supporting Centrus’s planned commercial enrichment expansion.
Why it matters: This is a commercial contract rather than a memorandum. It adds a customer and customer-backed capital to the domestic enrichment buildout, although fuel delivery, testing and commercial deployment remain ahead.
X-energy: Long Mott permit review reaches NRC advisory committee
The NRC’s Advisory Committee on Reactor Safeguards reviewed the construction-permit application for four Xe-100 modules at Dow’s Long Mott site. The NRC targets a final safety evaluation in November 2026; the permit decision date remains undetermined.
Why it matters: This is a concrete licensing step for a four-module commercial deployment, but it is not a construction-permit approval.
Oklo: New $1 billion ATM expands funding flexibility and dilution capacity
Oklo established an at-the-market program allowing it to sell up to $1 billion of Class A common stock over time. The filing creates issuance capacity; it does not mean the full amount has been sold.
Why it matters: The program can support reactor, fuel and project-development work while increasing potential dilution. Access to capital should be distinguished from project execution.
BWXT: National-security infrastructure pipeline advances
BWXT received a $4 million DOE/NNSA conceptual-design contract for the first module of a new Y-12 Lithium Processing Facility. Local officials also approved the site plan for BWXT’s Jonesborough expansion supporting a previously awarded contract worth up to $1.6 billion.
Why it matters: These steps reinforce BWXT’s specialized nuclear-manufacturing position, although the Y-12 follow-on award is competitive and Jonesborough is not an SMR fuel project.
Policy, Utilities and Fuel
Defense demand: The Crane project follows the Army’s selection of Antares, BWXT, General Atomics, Radiant and Westinghouse under Project Janus. Because the Crane supplier remains undisclosed, no company-specific award should be inferred.
Licensing: NRC staff have completed the final safety evaluation and environmental review for TVA’s Clinch River application. The Commission’s decision is targeted for fall 2026, but a permit has not yet been issued.
Fuel: Cameco’s August month-end industry averages were $89.68 per pound for spot uranium and $96.50 for the long-term price, up from $86.38 and $95.50 in July. Together with Centrus’s customer prepayments, the term premium supports the importance of dependable multi-year fuel and enrichment capacity.
AI and utilities: Neither week produced a new binding hyperscaler nuclear-power agreement. Google’s expected funding of generation and transmission upgrades for its Arkansas data center nevertheless illustrates how large loads can support infrastructure investment; the associated generation project is solar, not nuclear.
Competitive Watch
Deep Fission lowered and retrieved a full-size non-nuclear prototype canister to 100 feet using commercial drilling equipment. Its proposed reactor would sit roughly one mile underground.
Why it matters: This is early engineering validation, not evidence of a fueled reactor, commercial-depth installation or licensable power plant.
Bottom Line
The two-week signal was the widening of complete delivery ecosystems. European fleet programs added named technology, construction, manufacturing and financing partners; U.S. projects advanced through defense demand, fuel contracting and licensing checkpoints; and uranium’s term premium kept fuel security in focus. Binding contracts, permits, fuel deliveries, funded construction and repeatable manufacturing will matter more than headline capacity alone.
