NuScale Power said on 5 November 2026 that it has signed an agreement with Doosan Enerbility to fabricate the upper reactor coolant system of the NuScale Power Module — the step chief executive John Hopkins described as moving “from development to physical production.” The update is in a NuScale press release and the company’s Form 8-K for the same day.
The company ended the third quarter with $1.9 billion in cash, cash equivalents and short- and long-term investments. It also said it is deploying nuclear-specific AI tools developed with Nuclearn and NPX across engineering and knowledge-management functions, and that with MillenniTEK it is fabricating first-of-a-kind reactor safety components for the modules.
Hopkins said the Doosan contract “moves our Nuclear Regulatory Commission-approved design into actual build and sets the foundation for all modules to follow.” Each NuScale Power Module is framed as 77 MWe (250 MWt gross), with a twelve-module plant at up to 924 MWe — company specifications, not a new certification claim.
Fabrication is not the same as a customer offtake
The concrete news is supply-chain maturity: an upper RCS fabrication deal with a named heavy manufacturer, plus AI tooling and safety-component work. What the release does not do is name a new data-centre power buyer. NuScale says it continues to support commercial partner ENTRA1 Energy in dialogue with the Tennessee Valley Authority on what it calls the largest commercial nuclear deployment programme in US history. That remains dialogue as stated — not a signed TVA offtake TSN can invent for AI campuses.
Revenue and cost of sales fell year-on-year in the quarter, NuScale said, largely because prior-year work on Fluor’s FEED Phase 2 for RoPower had finished. Liquidity, not near-term module revenue, is the balance-sheet story this filing.
NuScale’s own financial update underlines how early commercial revenue still is: the year-on-year drop tied to completed RoPower FEED work shows engineering services can vanish from the top line while fabrication ramps. That is normal for FOAK nuclear vendors, but it means investors are underwriting cash runway and supply-chain proof more than module shipments this quarter.
Where NuScale sits in the nuclear-for-compute lane
US tech and utility buyers have been shopping for firm carbon-free power. TSN has covered Amazon, X-energy and AEP exploring twelve Xe-100 SMRs in Indiana, Japan’s plan to put capital into US reactors aimed at AI data centres, and a conditional DOE loan offer of up to $5bn for Constellation uprates. Those are parallel tracks. Folding NuScale into any of them as a confirmed hyperscaler customer would go beyond today’s sources.
The AI-data-centre power narrative creates a temptation to treat every SMR press release as a campus PPA. NuScale’s Q3 package resists that: the named industrial step is Doosan fabricating an upper reactor coolant system, and the named commercial thread is ENTRA1’s TVA dialogue. Nuclearn/NPX tooling and MillenniTEK safety components are supply-chain and engineering depth, not customer logos.
For compliance and project-finance readers, the Doosan step matters because first-of-a-kind SMR programmes stall when paper designs never meet steel. An upper RCS fabrication agreement is a manufacturing milestone on an NRC design-certified product. It still leaves licensing of specific sites, EPC execution, fuel supply and offtake as separate gates. A twelve-module, 924 MWe plant remains a configuration claim until a site and construction schedule exist in a primary filing.
UK readers watching Rolls-Royce SMR and Great British Nuclear should read this as a US vendor manufacturing update, not a UK project award. Cross-border relevance is competitive pressure on delivery timelines, not an offtake in Britain.
What to watch next
Public signs that the ENTRA1–TVA dialogue has hardened into a construction or power-purchase commitment; Doosan production milestones on the upper RCS; and whether NuScale’s $1.9bn liquidity is spent on further long-lead components rather than burn. NuScale’s filings name no data-centre or AI campus customer, so for now the story is fabrication and cash.
