Nuclear Waste Storage Site in West Texas Cleared for License

Publication Date: June 18, 2025

Overview

On June 18, 2025, the U.S. Supreme Court held 6–3 that the State of Texas and a private landowner lack standing to challenge the Nuclear Regulatory Commission’s (NRC) licensing of a consolidated interim storage facility for spent nuclear fuel in West Texas. The ruling reinstates the NRC’s September 2021 license to Interim Storage Partners (ISP) for a 40-year facility in Andrews County, Texas. The decision comes amid a multidecade impasse over a permanent national repository—most notably the stalled Yucca Mountain project—and revives federal efforts to centralize growing inventories of high-level radioactive waste at sites away from reactor locations.

Facts

Supreme Court Decision: On June 18, 2025, the Court reversed the Fifth Circuit’s vacatur of ISP’s license, ruling that Texas and Fasken Land and Minerals were not “parties aggrieved” in the NRC’s licensing proceeding and therefore cannot obtain judicial review — 6 Justices in the majority, 3 in dissent.
ISP License: The NRC licensed ISP in September 2021 to build and operate a facility in Andrews County capable of storing up to 5,500 tons of spent nuclear fuel and related high-level waste for 40 years (with a possible 40-year extension).
Holtec License: In May 2023, the NRC granted Holtec International a license for a consolidated interim storage facility in Lea County, New Mexico, authorizing up to 8,680 metric tons of commercial spent nuclear fuel stored in sealed canisters for 40 years.
Nuclear Waste Policy Act (1982): Congress established procedures for deep geologic repositories and interim storage, assigning the Department of Energy (DOE) responsibility for permanent disposal and generators’ responsibility for interim storage costs.
Permanent Repository Stalemate: Although Congress amended NWPA in 1987 to focus on Yucca Mountain, DOE halted licensing efforts in 2010, and Congress ceased funding soon after. No spent fuel has been emplaced at Yucca Mountain to date.
On-site Storage Today: Approximately 100,000 tons of spent nuclear fuel remain at over 120 reactor sites across 39 states in dry casks or cooling pools, growing by about 2,000 tons annually.

Perspectives

Nuclear Regulatory Commission (NRC):
The NRC maintains that its licensing process complied with the Atomic Energy Act’s hearing and intervention requirements and that only admitted parties may seek judicial review. It emphasizes the agency’s duty to regulate spent fuel storage safely and transparently.
Interim Storage Partners (ISP):
ISP argues that its Andrews County facility will relieve overcrowded reactor-site storage, bolster national security by consolidating vulnerable inventories, and adhere to strict NRC safety and environmental standards.
State of Texas (Governor Greg Abbott):
Governor Abbott contends that Texas law (effective 2022) bans high-level waste disposal outside reactor sites and that the federal government is overstepping its authority.
State of New Mexico (Governor Michelle Lujan Grisham):
Governor Grisham and the New Mexico Legislature have enacted laws intended to block high-level waste storage in Lea County. They emphasize local consent and environmental justice, warning against making rural communities de facto long-term repositories.
Fasken Land and Minerals:
Fasken, which attempted to intervene in the NRC proceedings, argues the project threatens landowners and fragile ecosystems, and that procedural barriers inadequately protect affected stakeholders.
Blue Ribbon Commission on America’s Nuclear Future:
The Commission’s 2012 report recommended a consent-based siting process for consolidated interim storage and permanent disposal, calling for transparent stakeholder engagement and flexible federal-state collaboration.

Considerations

Continued accumulation of spent fuel at reactor sites underscores the urgency of interim storage solutions and the risks of prolonged on-site storage.
The absence of a permanent repository since DOE’s 2010 withdrawal from Yucca Mountain sustains political, legal, and funding gridlock at the federal level.
Federal preemption of state bans raises constitutional questions about the interplay between state environmental authority and NRC licensing jurisdiction.
Consent-based siting frameworks may offer a path forward but require meaningful local engagement to resolve environmental impact concerns.
Successful operation of ISP and Holtec facilities could shape future nuclear energy policy and investor confidence in next-generation reactors.
Long-term stewardship, including transportation logistics and cask maintenance, will demand sustained oversight and funding.
