To replace the reactor vessel head, FirstEnergy purchased one from the mothballed Midland Nuclear Power Plant in Midland, Michigan. [ 26 ] The NRC determined that this incident was the fifth-most dangerous nuclear incident in the United States since 1979, [ 3 ] and imposed its largest fine ever—more than $5 million—against FirstEnergy for ...
Unit 2 was shut down in early January 2012 for routine refueling and replacement of the reactor vessel head. [48] On January 31, 2012, Unit 3 suffered a radioactive leak largely inside the containment shell, with a release to the environment below allowable limits, and the reactor was shut down per standard procedure.
A reactor vessel head for a pressurized water reactor. This structure is attached to the top of the reactor vessel body. It contains penetrations to allow the control rod driving mechanism to attach to the control rods in the fuel assembly. The coolant level measurement probe also enters the vessel through the reactor vessel head.

In December 2016, it was disclosed that a certificate of conformity for Unit 2's steel reactor vessel closure head (RVCH), supplied by Creusot Forge, had been forged by the manufacturer, violating safety standards and potentially undermining the vessel head's mechanical ability to withstand sudden breakdown in certain conditions if excess ...
Erosion of the 6-inch-thick (150 mm) carbon steel reactor head, caused by a persistent leak of borated water, at the Davis-Besse Nuclear Power Plant. The United States Government Accountability Office reported more than 150 incidents from 2001 to 2006 of nuclear plants not performing within acceptable safety guidelines.
