Located on the shores of Lake Erie near Oak Harbor, Ohio, the Davis–Besse Nuclear Power Station is an 894-megawatt pressurized water reactor now operated by Vistra Corp. The plant has a troubled safety record, with the Nuclear Regulatory Commission (NRC) placing two of its incidents among the top five most dangerous in the U.S. since 1979—most notably in March 2002, when workers discovered corrosion had eaten a football-sized hole into the reactor vessel head, triggering a two-year shutdown and a record $5 million NRC fine (plus a $28 million DOJ settlement) against then-operator FirstEnergy. Earlier, in 1977, a stuck-open relief valve foreshadowed the Three Mile Island accident, and a 1985 loss of feedwater event was caused by operator error. Although slated for closure in 2020 due to competition from natural gas, the plant was rescued by Ohio House Bill 6 (signed in July 2019), which provided $150 million in annual subsidies—legislation that later became the centerpiece of the Ohio nuclear bribery scandal revealed in July 2020. Construction began on September 1, 1970, and the reactor came online on July 31, 1978, named after utility executives John K. Davis and Ralph M. Besse.
