SUMMARY ORDER

Petitioner Nancy Burton challenges a decision of the United States Nuclear Regulatory Commission (“NRC”), which denied two petitions she filed in a license-renewal adjudication relating to the nuclear power facilities at Indian Point. In the first petition, petitioner applied for a waiver of certain generally applicable NRC regulations during the license-renewal adjudication in question. In the second petition, petitioner sought to intervene in the adjudication in order to present evidence that would otherwise be barred by the regulations for which she sought the waiver. The Atomic Safety and Licensing Board denied both petitions, and the NRC denied petitioner’s appeal of those conclusions. Relying on 28 U.S.C. § 2342(4), petitioner now challenges the NRC’s decision. 1 We presume the parties’ familiarity with the underlying facts, the procedural history of the case, and the issues on appeal.

*640 Our review of a final order of the NRC is governed by the Administrative Procedure Act (“APA”), 5 U.S.C. § 701 et seq. Pursuant to the APA, petitions for review of the NRC’s decisions must be denied unless the agency’s conclusions were “arbitrary, capricious, an abuse of discretion, or otherwise not in accordance with law.” Id. § 706(2)(a). Thus, our review is “narrow” and “highly deferential”; “[t]he test here is primarily one of rationality.” County of Rockland v. U.S. Nuclear Regulatory Comm’n, 709 F.2d 766, 776 (2d Cir. 1988) (quotations omitted). “ ‘If the [NRC] based its order on substantial relevant evidence, fairly ascertained, and if it has made no clear error of judgment, this court is not authorized to overturn that order.’ ” Id. (quoting Cross-Sound Ferry Servs., Inc. v. United States, 573 F.2d 725, 730 (2d Cir. 1978)).

Upon review of the instant petition, we conclude that petitioner has failed to demonstrate that the NRC acted arbitrarily or capriciously in denying her waiver petition. Absent such a waiver, it cannot be said that the NRC ran afoul of the APA by denying petitioner’s application to intervene in the license-renewal adjudication. We have considered petitioner’s remaining arguments and find them to be without merit. Accordingly, the petition is hereby DENIED.
