Subject: ITW beam tube repair 

Vacuumed out remainder of debris from the wall penetration, removed cradle and checked condition. Down stream support bracket sees advanced stages of material loss (OBO 20-30% loss). See attached photos.

RPG reports that the removed beam tube has 15k CPM on the interior of the beam tube.

Tank flange was cleaned as per 2009 repair report, looks OK. Video capture of flange inspection attached as .zip file.

.03" shim was inserted into the clamp indexing block.
