  949   Tuesday, June 16, 2015, 14:28 chad fisherSouth Hot-CellRepairTM2 TM2 Source Tray Installation/Water Block Sealing Surface Clean

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.

Jig was installed on module to retain module side waterblocks.

Blank-off remove was commenced, however due to and large amount of water coming out of the line to have the blank-off removed work had to stop till the water evaporates.

Waterblock sealing surface cleaning and polishing will continue tomorrow.

Also, upon installing the jig a piece of fiberglass that had previously been manual inserted between two of the water lines (early to mid 2000's) fell out.

  950   Wednesday, June 17, 2015, 14:21 chad fisherSouth Hot-CellRepairTM2 TM2 Waterblock Clean Polish

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.

Polishing commenced with 2000 grit wet sand paper. Paper was wet with isopropynol. 60 second cycles for double seal blocks, 30 second for singles. The 2000 grit pass was completed.

Polishing will finish tomorrow morning as well as removal of optics tray from source tray in preparartion for insertion of the source tray into the module tomorrow afternoon or Friday morning.

First picture is Tube heater Circuit D block before cleaning and second picture is after cleaning.

Window waterline has been successfully connected using 1 1/2 inch long non-blunt start 1/4-28 bolts.

All bolt torques have been checked with dial torque wrench and are confirmed to be tight to 90 in lbs.

Left manipulator now broken. Master side however, so repair can take place Monday or Tuesday.

The master wrist/tong cable has been replaced on the left manipulator. Everything appears to function well so far.

  958   Tuesday, June 23, 2015, 14:19 chad fisherSouth Hot-CellRepairTM2 TM2 Water Block Jigs Removed

Both halves of the water block jigs have been removed and the module is now ready for base vacuum leak and electrical checks.

During removal of the jigs the fiberglass that had been "shoved" by hand in between two of the lines in the early 2000's fell out again.

  960   Wednesday, June 24, 2015, 10:16 chad fisherSouth Hot-CellRepairTM2 TM2 Vacuum Leak Check

The following circuits have been vacuum leak checked and have not registered any leaks:

Circuit D, C, B, A, Coil2, EE, Ground Electrode, Mounting Support plate, Coil 1.

Left are Heat Shield and Window circuits which will be checked after blank offs are installed on the vcr terminations.

  963   Friday, June 26, 2015, 09:44 chad fisherSouth Hot-CellRepairTM2 TM2 Retrofit Status

On June 25th the following work was completed:

Optics tray was installed into TM2. The lower fastener on the vertical cable tray (IRH1585) needed to be removed and vertical cable tray rotated upwards as optics tray would not clear cable tray. Optics tray was intstaled, cable tray repositioned and screw re-inserted.

Modified water block for 9 pin connector was installed.

Steerers connected.

Ground Electrode water blocks were "repositioned" closer to there specified position to attempt eliminating the short between the ground electrode line and coil 1 circuit. This was successful but could still use a clamp or other method of ensuring the ground electrode line is in its "proper" place.

9 pin connector line was rerouted to ensure it does not contact anything it is not suppose to (Rerouting directions provided by Anders).

Enzel lens cable was installed.

Blank offs removed from window water lines and new gaskets installed in preparation for installation of the containment box.

  979   Friday, July 03, 2015, 11:33 chad fisherSouth Hot-CellRepairTM2 TM2 Coil Leak Progress

First thing this morning the hot cell was "cleaned up" in preparation for the return of TM2 for attempted verification and locating of leak on R/U coil circuit.

Containment box has been removed and front cover reinstalled to provide some modicum of shielding form the entrance and exit windows. Box was placed at an angle in the corner to try and minimize line-of-sight with potential worker(s).

Did notice some funny discoloration of both sides of coil water block "R" as seen in attached picture.
