The Perry Nuclear Power Plant is located on a 1100 acre site on Lake Erie, 40 mi northeast of Cleveland in North Perry, Ohio, US. The nuclear power plant is owned and operated by Vistra Corporation.
The reactor is a General Electric BWR-6 boiling water reactor design, with a Mark III containment design. The original core power level of 3,579 megawatts thermal was increased to 3,758 megawatts thermal in 2000, making Perry one of the largest BWRs in the United States.
Perry was expected to close in 2021 as it is no longer profitable to run when competing against natural gas plants. To avert this, Ohio House Bill 6 was signed into law in July 2019 which added a fee to residents' utility bills that funded subsidies of $150 million per year to Perry and the Davis–Besse nuclear plant to keep both plants operational. However, the bill was alleged to be part of the Ohio nuclear bribery scandal revealed by the United States Department of Justice (DOJ) in July 2020.
History
Perry was originally designed as a two-unit installation, but construction on Unit 2 was suspended in 1985 and formally cancelled in 1994. At the time of cancellation, all of the major buildings and structures for the second unit were completed, including the 500 ft cooling tower. It is possible that a second unit could be constructed on the site, but current economic and regulatory conditions are not conducive to doing so (in addition to back taxes that would be due to the "abandon in place" designations on many objects in Unit 2).
Eleven hundred acres at the Perry plant were designated in 1993 as an urban wildlife sanctuary by the National Institute for Urban Wildlife. The area has trees, shrubs, streams and ponds; and a habitat for heron, belted kingfisher, ducks and geese. The forested area is ideal for the crane-fly orchid, a rare species in Ohio. The site includes a wetland that contains spotted turtles, an endangered species in Ohio.
On March 28, 2010, there was a fire in a lubrication system for one of the water pumps that feeds water for generation of steam. Reactor power automatically lowered to 68% due to the reduction in feed water flow, and the fire was extinguished in less than three hours. Two plant fire brigade personnel were brought to a local hospital for "heat stress" following the fire. No customers lost power during this event. On February 9, 2016, the plant was unexpectedly shut down for maintenance to a recirculation pump. The reactor was brought back to full power by February 20, 2016.
In addition to Perry, Vistra Corp also owns and operates the Davis-Besse and Beaver Valley nuclear plants.{{cite web|title=Texas-based Vistra now officially owns the Davis-Besse, Perry and Beaver Valley nuclear plants
In July 2023, Energy Harbor applied for a license renewal for the Perry nuclear power plant, requesting an additional 20 years of operation. This license renewal for Unit 1 was officially approved on July 7, 2025 and will now expire November 7, 2046.
In March 2024, Texas-based Vistra Corp announced it had completed an acquisition of Energy Harbor Corp. and its nuclear generation fleet assets, which was previously announced in March 2023.

Surrounding population
The Nuclear Regulatory Commission defines two emergency planning zones around nuclear power plants: a plume exposure pathway zone with a radius of 10 mi, concerned primarily with exposure to, and inhalation of, airborne radioactive contamination, and an ingestion pathway zone of about 50 mi, concerned primarily with ingestion of food and liquid contaminated by radioactivity.
The 2010 U.S. population within 10 mi of Perry was 83,410, an increase of 8 percent in a decade, according to an analysis of U.S. Census data for msnbc.com. The 2010 U.S. population within 50 mi was 2,281,531, a decrease of 3.0 percent since 2000. Cities within 50 mi include Cleveland (36 mi to city center). Canadian population is not included in these figures.
Seismic risk
The Nuclear Regulatory Commission's estimate of the risk each year of an earthquake intense enough to cause core damage to the reactor at Perry was 1 in 47,619, according to an NRC study published in August 2010.
Security threats
At around 6:00pm EDT on April 7, 2021, the FBI's Cleveland Field Office tweeted that there was an ongoing security situation at the plant that necessitated a bomb squad. The following day, law enforcement disclosed that a 33-year-old Michigan man drove to the power plant and told plant security officers that there was a bomb in the trailer he was towing with his pickup truck. No bomb was found; the man was arrested.
