Davis-Besse's severely cracked concrete containment Shield Building a high-risk experiment!

Don't believe us? Just check out the NRC document, “Davis-Besse Nuclear Power Station, Unit 1 - Report of Facility Changes, Tests, and Experiments,” in an “Annual Operating Report Letter” dated May 21, 2018, with the NRC ML # ML18141A502. (emphasis added)

From 2010 to 2015, Toledo attorney Terry Lodge served as legal counsel for an environmental coalition, including Beyond Nuclear, Citizens Environment Coalition of Southwestern Ontario, Don’t Waste Michigan, and the Ohio Green Party, which challenged the Davis-Besse atomic reactor’s 2017-2037 license extension.

A major contention in opposition to the license extension was the severe cracking of Davis-Besse's concrete containment Shield Building, first revealed to the public in October 2011.

In July 2014, it was further revealed to the public that the cracks were actually growing, due to a process of Ice-Wedging Crack Propagation. That is, water locked in the walls of the Shield Building causes the cracks to grow by a half-inch, or more, in circumferential orientation, every time a freeze-thaw cycle occurs at Davis-Besse. A large number of freeze-thaw cycles occur at Davis-Besse, year after year.

Despite Davis-Besse’s industry record of most close calls with meltdown catastrophes, as well as its severely cracked containment structure (which is currently operating as an experiment, as shown above), NRC has approved 60 years of operations at the deeply troubled reactor (1977 to 2037).
