Background===

Energy Harbor Nuclear Corp.

In March of 2020, the Perry Nuclear Power Plant (PNPP) staff implemented License Amendment 187 that revised the Operating License to reflect a direct transfer of operating authority for the facility from FirstEnergy Nuclear Operating Company (FENOC) to Energy Harbor Nuclear Corp. (EHNC), a direct transfer of ownership of the facility from FirstEnergy Nuclear Generation, LLC (FENGen) to Energy Harbor Nuclear Generation LLC and an indirect transfer of ownership of the facility to Energy Harbor Corp.

Perrys License Renewal Application Perrys current operating license expires at midnight on 11/07/2026.

Perry was granted an exemption from specific requirements of Title 10 of the Code of Federal Regulations (10 CFR), 10 CFR 54.17(a)s requirement that an application for a renewed license be in accordance with Subpart A of 10 CFR Part 2, and, more specifically, 10 CFR 2.109(b). Section 2.109(b) provides timely renewal protection to licensees that submit sufficient license renewal applications at least five years before the expiration of the existing license. Thus, this exemption allows EHNC to submit a license renewal application for PNPP at least three years prior to the expiration of its existing license and, if the application is sufficient, to still receive timely renewal protection.
