NRC approves construction permits for four X-energy reactors at Dow site in Texas
The U.S. Nuclear Regulatory Commission approved construction permits for four X-energy Xe-100 reactors at Dow's Seadrift site on the Texas Gulf Coast. Dow has not yet made a final decision to proceed, and critics question the speed of the review and the reactors' safety claims.

Clay Sell has called the design "physically impossible to melt down."

Mixed · 2Edwin Lyman of the Union of Concerned Scientists said the NRC achieved the approval by pushing critical safety questions to a later date. In an earlier interview he called it a myth that the fuel is meltdown-proof. TechCrunchN ““The NRC only accomplished this feat by pushing consideration of critical safety questions to a later date—issues the NRC should’ve fully resolved before green lighting construction,” Edwin Lyman” Read at TechCrunch ↗ Inside Climate NewsLC ““It’s just a myth that this fuel is indestructible or meltdown-proof,” he said. “This fuel has vulnerabilities.”” Read at Inside Climate News ↗ Left · 1Local opposition also remains. Diane Wilson of San Antonio Bay Waterkeeper called the approval "outrageous" and noted that spent fuel will be stored on site because the U.S. lacks a permanent disposal site; the NRC dismissed legal challenges the group filed in 2025.

X-energy's April IPO raised $1 billion, but its shares trade at less than half the offering price and the permit gave only a small boost.

Proponents say small modular designs will speed construction and cut costs, though TechCrunch notes those advantages are unproven.

- Framing
- Inside Climate News treats the permit as a regulatory milestone and gives space to local opposition and safety scepticism about the new design and the expedited review.
- Emphasis
- The Texas Gulf Coast setting, community objections, the technology's safety features and critics' doubts, and the political push behind the fast review.
- Leaves out or plays down
- Says little about X-energy's finances, Amazon's backing or the company's share price.
- Charged language
- “Feds Greenlight”“outrageous”“myth”
- For example
-
“Diane Wilson, a retired fourth-generation shrimper from the tiny nearby town of Seadrift and director of San Antonio Bay Waterkeeper, a local environmental organization, remains deeply skeptical.” — Inside Climate News

- Framing
- TechCrunch covers it as a business and technology story: a startup's milestone set against investor sentiment, with a single safety critique.
- Emphasis
- X-energy's funding, Amazon's commitments, the IPO and the share price, and the unproven cost advantages of small modular reactors.
- Leaves out or plays down
- Does not mention local opposition, the dismissed legal challenges, the executive-order context for the expedited review, or Dow's pending final decision.
- Charged language
- “green light”“jolt”
- For example
-
“The nuclear industry has benefitted from strong interest from hyperscalers and data center developers, who are desperate for any and all sources of electricity.” — TechCrunch
“The new permit approval gave X-energy a small jolt yesterday, though it was only enough to recover last week’s losses.” — TechCrunch

- No small modular reactor currently operates in the U.S.
Where accounts differ
-
How safe the Xe-100 design and its fuel are

- Centre
- X-energy claims the design is safer than many existing reactors; the Union of Concerned Scientists questioned the claim and the speed of the permit.
-
Whether the review was rigorous
- Left
- NRC Chairman Ho Nieh says the NRC delivered rigorous reviews on an 18-month schedule; the article notes the review was expedited under Trump executive orders.
- Centre
- Lyman says the NRC pushed critical safety questions to later.
