Urenco USA broke ground August 19 on a 2.1 million SWU centrifuge expansion at its Eunice, New Mexico facility, the first new US commercial enrichment construction at this scale in decades.
In context: Global energy markets are absorbing two simultaneous pressures: climate events cutting nuclear output in Europe while long-horizon demand commitments pull capital into supply chain infrastructure years before the reactors they serve exist. This week, both landed at once.

Urenco USA breaks ground on 2.1M SWU National Enrichment Facility expansion; uranium (U3O8) spot near $90/lb, a 6-month high

First new LEU cascades in Eunice won't produce for years; advanced reactor HALEU supply remains limited to Centrus's demonstration at Piketon; most utility LEU contracts already locked long-term

A groundbreaking in Eunice is a 12-year investment commitment; uranium crossing $89 this week is a 12-month demand signal. The two are tracking the same thesis at different time horizons.
This week at a glance
-
Plant focuses on low-enriched uranium for the conventional reactor fleet; HALEU supply remains Centrus's lane at Piketon.
-
The proposed rule would add a 1-year cap on EAs (environmental assessments) and a 2-year cap on EISs (environmental impact statements), eliminate the mandatory draft EIS step, and create new categorical exclusions for subsequent license renewals, uprates, and microreactor licensing; NRC projects $135M in 10-year savings.
-
Kazakhstan's Kazatomprom, the world's largest uranium producer, mines via in-situ recovery requiring sulfuric acid; the construction suspension introduces near-term supply uncertainty.

Palisades received an NRC
fitness-for-duty exemption in August, the latest regulatory clearance step as Holtec prepares for the first US commercial reactor restart
No formal restart authorization has been issued by the NRC; the exemption clears one administrative prerequisite on Holtec's path to restart.

Stat of the week
$89.50
Uranium spot price per pound for the week of August 25, 2026, the highest level in six months and up roughly 4.7% since mid-July, per TradeTech data. The move follows Kazatomprom's announcement that construction on its sulfuric acid plant was suspended after workers discovered paleontological specimens at the site, triggering a regulatory requirement for an official permit before work can resume. A sustained disruption at Kazatomprom would constrain the acid supply for in-situ recovery mining, the source of the majority of Kazakh uranium output.
In depth
Reference: terms in this issue
SWU (Separative Work Unit): The standard measure of uranium enrichment work; one SWU represents the effort needed to separate a kilogram of enriched uranium from a given quantity of natural uranium feed.
Categorical exclusion (CatEx): An NRC determination that a class of action has no significant environmental impact, requiring no environmental assessment or full environmental impact statement.
In-situ recovery (ISR): Uranium mining by pumping acidic solution underground to dissolve uranium from the ore body, then recovering it at the surface; the dominant mining method in Kazakhstan.
Deal
Urenco USA National Enrichment Facility: First New US Centrifuge Capacity in Decades
Before: The National Enrichment Facility in Eunice, New Mexico, has operated as the sole US commercial uranium enrichment plant on Urenco's gas-centrifuge technology. The only other domestic enrichment construction underway is Centrus's HALEU (high-assay low-enriched uranium, the fuel advanced reactors run on) demonstration at Piketon, Ohio, under a $900M DOE contract, producing at a much smaller scale for advanced reactor fuel. The Urenco-Antares supply deal (May 2026, Issue 11) opened a Western HALEU supply lane from Capenhurst, UK, but committed no new US ground construction.
Now: Urenco USA held a groundbreaking ceremony August 19 at the NEF, with DOE Secretary Chris Wright and Urenco CEO Boris Schucht on site. The multi-billion-dollar investment adds 2.1 million SWU of new LEU enrichment capacity. Initial cascades
start production in 2032. The new plant is focused on LEU for the conventional reactor fleet, separate from HALEU production, which remains Centrus's lane at Piketon.

Regulatory
NRC Part 51 NEPA Overhaul: Comment Period Closes, Final Rule Ahead
Before: NRC's NEPA regulations in 10 CFR Part 51 have governed environmental review of nuclear facilities since the 1970s, requiring full Environmental Impact Statements for most major licensing actions with no hard time limits. The Long Mott and Crane EA-not-EIS precedents (Issues 7 and 8) used existing NEPA flexibility, but no rule change. The NRC proposed its Part 51 overhaul on July 7, 2026 (FR docket NRC-2025-0478), opening the most significant proposed reform in decades: 1-year cap on EAs, 2-year cap on EISs, mandatory draft EIS eliminated, scope narrowed to radiological impacts, and new categorical exclusions for subsequent license renewals, uprates, microreactor licensing, and advanced reactor demonstrations.
Now: The public comment period
closed August 21, 2026, at 11:59pm ET. NRC projects $135 million in 10-year regulatory savings. Environmental groups and several congressional members have called the proposal a rollback; industry advocates argue the current review timelines add years without corresponding safety benefit. NRC now processes comments and drafts the final rule.

Uranium Breaks $89 as Kazatomprom Acid Plant Hits a Permitting Pause
Before: Uranium spot has traded in the $85–$88 range through most of summer 2026. Kazakhstan's Kazatomprom, the world's largest uranium producer, mines primarily via in-situ recovery (ISR), a process requiring sulfuric acid to dissolve uranium underground before recovery at the surface. A new acid plant was under construction to support Kazatomprom's production expansion plans.
Now: Uranium spot
reached $89.50/lb in late August, up roughly 4.7% since mid-July, per TradeTech data. The move follows Kazatomprom's announcement that construction on the sulfuric acid plant was suspended after workers discovered paleontological specimens at the site, triggering a regulatory requirement for an official permit to resume. Kazatomprom has not announced a production cut, but a sustained acid supply disruption would constrain its ISR mining output, introducing near-term supply uncertainty at a moment when US reactor demand signals are rising.

Question of the week
“Urenco USA just broke ground on a new centrifuge enrichment expansion in New Mexico, with first production in 2032. Is that timeline fast enough for utilities signing reactor contracts today, or will the enrichment supply gap cost them?
