Toshiba-Westinghouse AP1000 New Nuclear Power Station Piping Defects Appear Never-Ending; Any Part You Want, As Long as It’s Defective? On September 29th, the US NRC reported piping deviations for the Vogtle AP 1000 “two flanges identified with deviations on Passive Core Cooling System pipe spools for the Vogtle Unit 3 AP1000r project had incorrect raised-face dimensions. This appears to have been caused by the two flanges being transposed due to an inadvertent fabrication error that occurred at the pipe spool supplier’s facilities (CB&I Laurens). The error was subsequently discovered after delivery to the fabrication facility (Aecon Industrial).” And, what does this mean? Did they replace it? Or? An expert assures me that this means that they did the equivalent of forcing a door shut, which doesn’t want to go. It should have been replaced rather than corrected: “The flange configuration was corrected and the Q223 Mechanical Module was delivered to the Vogtle Unit 3 site…” Thus, Aecon is potentially producing defective “modules” in Canada. Greenberry of Vancouver, Washington has also made defective modules: The Greenberry facility seems to be in Oregon.
