2329:(DOJ). The deferred prosecution agreement related to the March 2002 incident. The deferment granted by the NRC were based on letters from Davis–Besse engineers stating that previous inspections were adequate. However, those inspections were not as thorough as the company suggested, as proved by the material deficiency discovered later. In any case, because FirstEnergy cooperated with investigators on the matter, they were able to avoid more serious penalties. The company paid $ 28 million under a settlement with the Justice Department. $ 23.7 million of that were fines, with an additional $ 4.3 million to be contributed to various groups, including the 345: 2442:
license extension to expire on April 22, 2037. On March 31, 2018, FirstEnergy Nuclear Operating Company filed for Bankruptcy protection. Around that time, the company indicated it would close the nuclear plant. In 2019, Ohio lawmakers debated a $ 9/MWh subsidy to keep Davis–Besse open. House Bill 6 was signed into law on July 23, 2019, and FirstEnergy announced it would refuel Davis–Besse and rescind its deactivation notice on July 24, 2019. It was later learned that the bill itself was a part of a public corruption scheme revealed by the Justice Department in July 2020.

The NRC imposed an over $ 5 million fine, its largest fine ever to a nuclear power plant, against FirstEnergy for the actions that led to the corrosion.
