Wires for TM#2 steering elements, and png gauge have been run down to the containment box level. Chad has placed them in the little cable trays. Slack
has been pulled back. and termination of the wire will be done on the 7th of May. A modification was done to the signal line of the png gauge wire ultem
block, as grounded screw was inserted to allow for strain relief so the end would hopefully quit breaking. See attached pictures for the details. |

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. |
