Urenco's New Mexico plant starts its sixth of eight new cascades in a 700,000 SWU addition
Urenco USA has begun installing the sixth of eight new centrifuge cascades in New Mexico, a 75% mark on a 700,000 SWU addition. That tranche is a tenth of the 7 million SWU planned over the next decade, a smaller step than the percentage suggests.
The Product Desk
Three figures: the Eunice, New Mexico facility offers 4.3 million SWU a year now; the facility's goal is 7 million SWU over the next decade; US demand implied at today's level is roughly 12.9 million SWU, if 4.3 million SWU is about a third of it.

What happened
- Urenco's Eunice, New Mexico facility offers 4.3 million SWU a year today, about a third of US demand, according to the report.
- Installation of the seventh cascade is expected to finish by the end of the year, with the eighth and final cascade to follow in 2027.
- The longer plan is 7 million SWU of capacity over the next decade, a goal that sits well beyond the eight-cascade tranche now under way.
Why it matters
- Who has to decide decision Fuel buyers have to decide how much of the later cascades to count as firm supply when the only delivery assessment on record is the company's own, from a press release.
- What it limits constraint At today's demand level the whole 700,000 SWU tranche adds about 5% of demand, so most US enrichment still comes from outside the plant through 2027.
- What doesn't add up contradiction The headline frames 75% as progress on the capacity expansion target, while the body ties it to a 700,000 SWU tranche. Against 7 million SWU, the two scales differ by a factor of ten.
- What it sets up precedent Urenco says this tranche's experience will support larger programs, so cascades seven and eight are the first test of whether its schedule claim holds.
A fuel buyer who reads the interestingengineering.com headline about a 75% capacity expansion target [3] and files it against the 7 million SWU goal [1] has picked the wrong denominator.
The 75% counts cascades. Urenco is adding eight of them at its existing site between 2025 and 2027, for 700,000 SWU [2], and it reached the milestone as installation of the sixth began [5]. If the eight are equal in size, 75% of the tranche is 525,000 SWU [9]. Against 7 million SWU, that is 7.5% [10].
Urenco's own wording points past the current work. "This experience will support our larger capacity programs in the years ahead as we look to increase our enrichment production by more than 50% to meet the needs of our customers with traditional and advanced reactors," said Jody Blackshear, Managing Director of Urenco USA, in a press release [18]. Seven million SWU would be about 63% more than the 4.3 million SWU on offer today [12], consistent with his "more than 50%".
On delivery, Blackshear said: "We are consistently delivering new capacity to help fuel the US nuclear industry and allied nations, and our teams are doing it ahead of schedule and on budget" [17]. The report repeats Urenco's claim and includes no import figures, so a decline in reliance on imported enrichment is not something it shows.
According to the report, US nuclear facilities buy enrichment internationally, and only one US facility can enrich uranium [7]. A milestone headline invites teams to tell themselves that the buying pattern is already shifting. The Eunice site covers about a third of demand [4], which leaves about two-thirds outside it [13], and the report says the US plans to lean harder on nuclear power [8]. At today's demand level, 7 million SWU would cover about 54% [15].
In our view, a buyer should test any capacity milestone on two axes. The first is the denominator: the 700,000 SWU tranche due by 2027 [2], or the 7 million SWU decade goal [1]. The second is the count: work started, or capacity running. Urenco's 75% sits at tranche and started [5]. A supply plan needs decade goal and running. The cascades still to come are the first dated additions to running capacity [6]. Until then we would plan on the 4.3 million SWU now offered [4] and treat later volume as upside. The cost of that choice is under-counting capacity if the company keeps ahead of its schedule.
What to watch
- Whether the seventh cascade finishes by the end of the year and the eighth installs in 2027, as the report expects.
- Whether Urenco publishes dates and sizes for the programs that would take the site from the 700,000 SWU tranche to 7 million SWU.
- Enrichment import data, which would show whether US reliance on imports falls as new cascades come online.

Urenco's enrichment facility in Eunice, New Mexico currently offers 4.3 million SWU per year, about a third of US demand.

With the beginning of installation of the sixth cascade, Urenco has reached the milestone of 75 percent of the planned capacity upgrade.
- [6]
Installation of the seventh cascade is expected to be completed by the end of the year, and the eighth and final cascade will be installed in 2027.
- [7]
Nuclear facilities in the US rely on international purchases to feed their reactors, and only one facility in the US can actually enrich uranium.

The US is planning to increase its dependence on nuclear energy in the future.

If the eight cascades are equal in size, 75% of the 700,000 SWU tranche is 525,000 SWU.

525,000 SWU is 7.5% of the 7 million SWU target.
- [11]
The 700,000 SWU tranche is one tenth of the 7 million SWU target, so reading the 75% against 7 million SWU would overstate the tranche's scale by a factor of ten.
- [12]
7 million SWU is about 63% more than the 4.3 million SWU the Eunice site offers now.
- [13]
If the Eunice site covers about a third of US demand, about two-thirds of demand sits outside it.
- [14]
If 4.3 million SWU is about a third of US demand, demand is roughly 12.9 million SWU at today's level.
- [15]
At today's demand level, 7 million SWU would cover about 54% of US demand.
- [16]
The full 700,000 SWU tranche equals about 5% of today's implied US demand of roughly 12.9 million SWU.
