|
TM2 has been successfully de-shuttered.
All went pretty much according to plan except I had to remove one fastener out of the upper wiring harness (the one that has just been installed)
to allow for enough clearance to rotated the shutter guide out of the way...I shutter to think what would have happened otherwise...anyways... |

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. |

Fiberglass that fell out yesterday was put back in place (as well as possible).
Cleaning took place this morning with excellent results. Cleaning was performed with red scotch brite on the cleaning tool, air pressure at 40
psi while running, with one 60 second cycle. Three blocks (EE, HS and Window) needed a second pass to remove the indium. |
