With Federal Funding Windfall, X-energy Advances Small Nuclear Reactor
The title of this post, is the same as this article on Canary Media.
This is the sub-heading.
The Amazon-backed firm is aiming to build up to 144 of its novel Xe-100 reactors as the U.S. government seeks to revitalize an industry beset by rising costs
These three initial paragraphs add more detail.
The federal government has thrown its weight into reviving America’s long-stagnant nuclear industry, and X-energy’s first-of-a-kind reactor project is among the biggest beneficiaries so far.
The U.S. Department of Energy last month said it would award $1 billion to X-energy, an Amazon-backed advanced nuclear startup working to bring four novel 80-megawatt electric reactors online at a Dow Chemical facility in Seadrift, Texas, in the early 2030s.
The award nearly doubles the federal government’s commitment to X-energy, following a $1.2 billion investment in early 2021. Both tranches were structured as 50-50 cost-sharing agreements under the DOE’s Advanced Reactor Demonstration Program, launched in 2020 to commercialize next-generation nuclear technologies.
Note.
- It looks like X-energy are well-funded.
- It also looks like they have received funding under two different presidents.
- I like Dow’s concept of using nuclear to power a chemical complex, which needs both lots of electricity and heat.
- If they build 144 reactors, this will be twelve of the 12-pack power station, that they have said they will build at Hartlepool and I wrote about in Hartlepool Nuclear Reactor Moves To UK Regulatory Assessment.
The next phase would appear to be up to the regulators.
The article on Canary Media is well worth giving a full read.
These are some important highlights.
Dow Seem Enthusiastic And Would Be An Ideal First Customer
In any large project the first customer is always important.
- Dow seem to fit the part well.
- I also suspect, that as Dow turned over around $40 billion in fiscal year 2025, they know what they want.
Even in nuclear power, the customer is generally right.
Has X-energy Found Any Customers For The Xe-100?
I asked Google AI, this question and received this answer.
Yes, X-energy has secured major commercial customers and strategic partners for the Xe-100 reactor.
Key Customers and Partners
Dow: Partnering to deploy an Xe-100 four-pack plant at the Seadrift chemicals manufacturing site in Texas to provide low-carbon heat and power.
Amazon: Bankrolling and collaborating on up to 12 Xe-100 units via Energy Northwest in Washington state, alongside broader clean energy scaling for AI infrastructure.
Centrica: Partnering in the UK to deploy a potential fleet of up to 6 GW (10 to 20 reactors), targeting the Hartlepool site.
Energy Northwest: A Washington public power utility working collaboratively on project deployment frameworks.
Note.
When, the four partners, of which I was one, started to develop the Artemis project management system, the salesman of the four, did a survey of who might buy.
A proportion of these became valuable clients.
As X-energy also has a world-class engineering partner from Japan and Korea, I feel that they have done their preparation thoroughly.
Where Is The TRISO Fuel To Be Made?
According to the Canary Media article, it will be made near Oak Ridge National Laboratory in Tennessee.
- This could be handy for support.
- It could ease recruiting some of the staff with the right experience.
- There may also be useful sub-contractors in the area, with the right experience and certification.
The location is an excellent one.
Has Centrica Been Recruited Because They Are British?
According to its Wikipedia entry, the Dragon reactor, which used TRISO fuel, was generally considered extremely successful.
So by inviting Centrica to be involved, will X-energy be able to get access to the British files concerning the details of the Dragon reactor?
Their interpretation may be the difference between success and failure of the project.
I wouldn’t be surprised that there is a very trustworthy and knowledgeable network of very elderly British nuclear engineers, who enjoy meeting in pubs, with only the best real ales.
