Beyond Nuclear brings interim storage case back to Supreme Court

The U.S. Supreme Court may once again scrutinize the Nuclear Regulatory Commission’s authority to license consolidated interim storage facilities for commercial spent nuclear fuel. The antinuclear group Beyond Nuclear has filed a petition with the court for a writ of certiorari review of an August 2024 appeals court decision rejecting the group’s lawsuit against the licensing of Holtec International’s New Mexico storage facility, the HI-STORE CISF.

Beyond Nuclear is arguing that the NRC’s decision to license the HI-STORE CISF and deny the group’s hearing request violated the Nuclear Waste Policy Act (NWPA) and the Administrative Procedure Act, as well as the constitutional separation of powers doctrine. The group also contends that the NRC manipulated the hearing process to deny the group its right to a “day in court.”

The petition was filed on October 31 and docketed on November 4, with docket No. 25–540.

Litigating the merits: The U.S. Supreme Court in June ruled against Texas in its case regarding the licensing of Interim Storage Partners’ proposed CISF in Andrews County, Texas. The court found that plaintiffs Texas and Fasken Land and Minerals did not have standing as “parties aggrieved” to challenge the NRC license, sending the case back to the 5th Circuit Court of Appeals to be dismissed. As directed by the Supreme Court, the 5th Circuit dismissed the petitions against both the ISP and Holtec CISFs on October 20.

In NRC v. Texas, however, the Supreme Court did not weigh in on the NRC’s authority under the Atomic Energy Act and the NWPA to license private companies to store spent nuclear fuel at away-from-reactor sites.

In its petition to the Supreme Court, Beyond Nuclear claims that Holtec’s NRC license violates the NWPA, as the law prohibits the Department of Energy from taking any ownership of spent fuel until a deep geologic repository is licensed and operating.

Beyond Nuclear, together with Fasken, made similar arguments in their 2024 petition to the D.C. Circuit Court of Appeals. The court, however, rejected that argument, finding that because Holtec “sought a license for the lawful storage of privately owned spent fuel, and only the conditional storage of DOE-titled fuel if such storage became lawful, the Commission concluded that Beyond Nuclear had failed to raise a genuine dispute of law or fact.”

New Mexico pause: In October, Holtec canceled its agreement with the Eddy-Lea Energy Alliance, its partner in building the HI-STORE CISF. The company cited ongoing state resistance to the facility for the decision. In addition, Holtec said the canceled agreement would allow the company to work with other states that may be interested in interim storage projects.

Beyond Nuclear, however, has denigrated Holtec’s announcement as a “ruse,” claiming the company could be waiting until the political environment is more favorable to the project, or that Holtec may sell its license to another company for development in New Mexico.
