|
Today cleaning and polishing pads were inserted into the hot cell.
Module side waterblock jig installation was attempted however one of the locking tabs/latches (ITA2405?) came undone/fell off. Luckily, I had old,
obsolete jigs in the hot cell so I was able to remove parts I needed from an old one and rebuild the current one. |
