Perry Nuclear Generating Station

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-foot-tall (150 m) cooling tower. It is possible that a second unit could be constructed on the site, but current economical 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.[9]

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.[10] 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.[11]

In addition to Perry, Energy Harbor also owns and operates the Davis-Besse and Beaver Valley nuclear plants.[12]

The Nuclear Regulatory Commission defines two emergency planning zones around nuclear power plants: a plume exposure pathway zone with a radius of 10 miles (16 km), concerned primarily with exposure to, and inhalation of, airborne radioactive contamination, and an ingestion pathway zone of about 50 miles (80 km), concerned primarily with ingestion of food and liquid contaminated by radioactivity.[13]

The 2010 U.S. population within 10 miles (16 km) 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 miles (80 km) was 2,281,531, a decrease of 3.0 percent since 2000. Cities within 50 miles (80 km) include Cleveland (36 miles (58 km) to city center). Canadian population is not included in these figures.[14]

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.[15][16]
