The most severe occurring in March 2002, when maintenance workers discovered corrosion had eaten a football-sized hole into the reactor vessel head. [4] [5] The NRC kept Davis–Besse shut down until March 2004, so that FirstEnergy was able to perform all the necessary maintenance for safe operations. The NRC imposed an over $5 million fine ...
In the U.S., at least 56 nuclear reactor accidents have occurred. [2] The most serious of these U.S. accidents was the Three Mile Island accident in 1979. According to the Nuclear Regulatory Commission, the Davis–Besse Nuclear Power Station has been the source of two of the top five most dangerous nuclear incidents in the United States since ...
Erosion of the 150-millimetre-thick (5.9 in) carbon steel reactor head at Davis-Besse Nuclear Power Plant, in Oak Harbor, Ohio, USA, in 2002, caused by a persistent leak of borated water. The Hanford Site, in Benton County, Washington, USA, represents two-thirds of America's high-level radioactive waste by volume.
As 2021 comes to a close, the News Herald is reviewing the Top 10 stories of the year, including violations at Davis-Besse and the COVID-19 vaccines.
Severe corrosion of reactor vessel head forced 24-month outage of Davis-Besse reactor. 0: 143: 3 April 10, 2003: Paks, Hungary: Collapse of fuel rods at Paks Nuclear Power Plant unit 2 during its corrosion cleaning led to leakage of radioactive gases. It remained inactive for 18 months. 0: 3 August 9, 2004: Fukui Prefecture, Japan
Many are not reactor based events, or do not have any core related damage. We also see things like Davis Besse's reactor head degradation on here. While this was a very bad situation that left the reactor with low safety margin to the potential for a loss of coolant accident, nothing actually occurred.
The third levy is a 3.6-mill emergency levy, originally passed in 2018 after the devaluation of Davis-Besse Nuclear Plant, and will cost about $126 per year for a $100,000 home, Widmer said.
Severe corrosion of control rod drives in the reactor head forces 24-month outage of Davis-Besse reactor: 0: 143: January 15, 2003: Bridgman, Michigan, USA: A fault in the main transformer at the Donald C. Cook nuclear power plant causes a fire that damages the main generator and back-up turbines: 0: 10: June 16, 2005: Braidwood, Illinois, USA
