conductor insulators itd0053 and 54 have been replaced on TM2. All fasteners (1/4-20 x 1 1/4 vented) torqued to 60 in lbs.

  1380   Monday, October 24, 2016, 14:44 chad fisherSouth Hot-CellStandard OperationTM2SiC#35SiC#35 installed

Sic#35 has been installed onto TM2. High current fasteners torqued to 130 in lbs.

Mating of the 9 pin connector was extremely problematic but in the end I was able to get it to mate properly. Noticed left (when facing module in hot cell) febiad coil left twisted a bit when torqued up.

Chad and I did a leak check on TM4 HS line with new Ta target installed. Base leak rate 0.0xE-9 atm.cc/sec. base pressure 0.0XE-4.   splayed 2 helium to each VCR joints and did 10 seconds helium flush. No response on LD during the test. The HS line is leak free so far. It will be helium pressurized at TCS later.

Chad and I leak checked TM2 HS line with new UCx target installed. Helium spray  2 seconds on each joint and 10seconds flushing around target in SHC. LD base LR: 0.0XE-9atm.cc/sec, base pressure:0.0XE-4 torr. No response has been found on LD during check. The line is leak free.

  1428   Friday, January 27, 2017, 08:44 chad fisherSouth Hot-CellStandard OperationTM2Ta#50UCx #18 - Ta Feibiad Dummy installed. Target Change Waterline interference

On Tuesday, January 24th UCx#18 was removed from TM2 and Ta febiad dummy installed. I encountered the same issue mounting the new target as last time. Was able to determine that the issue is the routing of the waterlines to the right-hand (as viewed from the operator) high current tube heater. The lines interfer the the target mounting plate (bottom right hand corner).

On Thursday, January 26th UCx#18 and Ta#50 were inspected and packaged into spent target pails, move to storage vault.

  1439   Wednesday, February 15, 2017, 12:07 chad fisherSouth Hot-CellMaintenance  Manipulator 'Z' motion cable replacement preparation status

Aaron and I completed assembling (re-assembling) the clean spare on Tuesday, February 14th to assist in determining a procedure for replacement of the 'Z' motion cable on the south hot cell manipulators.

 

The anchor point in the slave end of the clean manipulator could not be found as the manipulator stand is too low and does not allow full extension of the slave end.

 

Did some poking around on the in-situ manipulator in the south cell and was able to find the anchor point viewing it with the in cell camera (see blurry attached photo).

 

Was able to then find reference to the "cable clamp" in the parts list and drawing for the slave end. Also, confirmed there is not a procedure in the manual for a CABLE 'Z' motion system as we have, only a tape driven system. The procedure should however be very similar safe this mystery anchor point I discovered today and how readily this anchor point can be worked in.

  1441   Monday, February 27, 2017, 14:23 chad fisherSouth Hot-CellRepair  Manip. 'Z' motion cable run through

Aaron and I successfully completed a run through on the procedure to replace the 'Z' motion cable. I will be writing up the procedure for review and we will be performing more run through-s for practice before the actual job.

  1448   Friday, March 10, 2017, 09:19 chad fisherSouth Hot-CellStandard Operation  South Hot Cell Field Measurements

The fields in the hot cell have been measured by means of a pole monitor through the tool port. Field was measured to be 25 uSv/h.

  1449   Tuesday, March 14, 2017, 07:34 chad fisherSouth Hot-CellMaintenance  Hot Cell Fields

I have re-measured the fields in the hot cell. Fields at shield door Al cover are 101 uSv\h, in cell at the east manipulator are 245 uSv\h, and the largest field is 1.84 mSv\h...this appears to be the high current fasteners removed from the last target.

  1450   Tuesday, March 14, 2017, 11:46 chad fisherSouth Hot-CellMaintenance  'Z' motion cable dry run

Did a dry run with the latest procedure with Dan Mcdonald. Elapsed time was approximately 30 min.

  1451   Wednesday, March 15, 2017, 07:45 chad fisherSouth Hot-CellMaintenance  South Hot Cell Fields

I have moved the suspected "hot" items in the hot cell and placed them under some lead bricks. I have re-measured the fields and it has been reducded to 90 uSv\h at the manipulator repair area and 110 uSv/h at the previous 1.82 mSv\h area.

  1453   Thursday, March 16, 2017, 12:24 chad fisherSouth Hot-CellMaintenance  West 'Z' motion cable replacement

The west 'Z' motion cable on the east manipulator has successfully been replaced. The job took slightly less than an hour (including inspection of the scissor table hoses) and I received 0.075mSv. Scissor table hoses appear to be fine and also didn't "shed" or flake at all when checked by hand.

  1457   Wednesday, March 22, 2017, 14:05 Travis CaveSouth Hot-CellStandard OperationTM2test targetmodule moved

TM#2 has been moved from the east target station to the south hot cell.
