After all the talk of containment buildings because of Three Mile Island, Chernobyl and Fukushima, we now have the NRC and the nuclear industry engaging in NewSpeak because their facade of a foolproof system is, quite literally, showing cracks.
Are you fooled?
Davis Besse Nuclear Power Plant
Shallow Dome Containments For Pressurized Water Reactors (PWR) http://www.psctendon.com/nuclear/containmentdesign.html From one local paper:
Additional hairline cracks were discovered at the shield building of the Davis-Besse nuclear power plant in Ohio, reactor owner FirstEnergy said Monday. But both the company and a nuclear regulatory agency official said there is no immediate safety concern....

More cracks were found in architectural design components on the concrete "shield building" at the Davis- Besse Nuclear power station.
Jennifer Young, spokeswoman with First Energy, said hairline cracks were found in 15 out of the 16 design components of the building.
The architectural elements protrude 18 inches beyond the main wills of the 2 1/2 foot thick reinforced concrete...

There Are No Cracks in Davis-Besse’s Containment
Posted by Moderator on October 24, 2011
The NRC was informed by FirstEnergy on October 10 that it had identified what looked like a crack in the concrete shield building of the Davis-Besse nuclear power plant in Oak Harbor, Ohio. The plant had been shut down and workers were starting to cut a hole in the side of the building in order to move and replace the reactor head when they found the crack. The shield building is made of about three feet of concrete reinforced with two to three-inch steel rods.
It’s important to emphasize that the shield building at Davis-Besse is not the reactor containment vessel. That vessel is made of one-inch thick welded steel and sits inside of the shield building separated by about four and a half feet of hollow space. The shield building’s primary function is to protect the containment building against external hazards. The steel vessel is designed to keep the radiation inside the reactor from reaching the environment.
The Nuclear Regulatory Commision link has an apostrophe and won't post here properly. You can cut and paste these two parts in the address bar:

Just who is it "important to emphasize" this verbal sleight of hand to?
