- Updates to LRA associated with implementation ofLR-ISG-2012-01, "Wall Thinning Due to Erosion Mechanisms," that was issued on April 19, 2013.

This LRA update is part of a corrective action for submerged pump casings and/or associated supports that were inadvertently omitted from the LRA. The error has been entered into the Callaway Corrective Action Program. The corrective action process has confirmed that no additional LRA updates are required for submerged pump casings and their associated supports.
