  1130   Tuesday, November 24, 2015, 14:00 chad fisherSouth Hot-CellRepair  Compressible waste sorting.

Residual fields from the remaining compressible waste were still too high (as far as I'm concerned) so I have unpacked all compressible waste looking for a "hot" item that has snuck into these items.

I have a hand full of small bolts (possible target components), a hand full of target material/dust (including an entire target disc), and some cloths that had clearly been used to wipe the table (they are black with target dust).

These items will be disposed of with the next spent target.

  1292   Tuesday, July 26, 2016, 11:22 chad fisherSouth Hot-CellMaintenance  Soth Hot Cell Waste Storage Vault Tunnel

The two 45 gal (m) drums of waste removed from the south hot cell in December 2015 and January 2016 were transferred from the north hot cell to the shaft of the east vault tunnel on Monday, July 25th 2016 and subsequently to the east tunnel bunker in the vault tunnel on Tuesday, July 26th, 2016.The first drum (removed from the hot cell in December) containing both activated and contaminated metals was measured at 900 uSv/hr @ .5 m and the second drum (removed from the hot cell in January 2016) containing compressible items such as tank suits and plastic was measured at 150 uSv/hr @ .5 m.

Items were filed for storage/disposal with RPG under item number 1395 on the radioactive storage form.

Drums were transported to the vault tunnel using the 500 Mev Shield Flask (Drawing E-7097) with some minor modifications, namely a 1/4" thick Aluminum plate with four holes that line up with the holes in the bottom flange of the flask. This plate provided a bottom for the flask so that a drum could be contained within the flask during craning. Holes in the plate where countersunk for a 1/2" flat head bolt. Four bolts were also modified to accept 3/16 hair pins. 3 plates with clearances holes for the bolts were also manufactured to act as washers.

Procedure was as follows: With plate, washers and pins installed onto the flask, a modified drum dolly (5" spacers added to the casters) was placed inside the flask. Drum was craned into the flask using the automatic drum lifter. Flask with drum loaded was moved to the Meson Hall loading bay then craned to the B2 level of the Meson hall. Hair pins were pulled from the flask and the flask was then craned up leaving the drum (which was on the dolly firstly installed into the flask) and the plate. Drum on dolly was rolled to vault access shaft where it was craned off the modified dolly using the automatic drum lifter and down the access shaft to the vault tunnel level.  A second drum dolly was waiting at the bottom level and drum lowered onto it. Procedure was repeated for the second drum

Was vault was open , drums were wheeled into the vault tunnel and into a bunker that had been modified to accept these drums. Drums were lifted off dollies and put in place in bunker which had blocks installed to cover the entrance provided for installation.

  1296   Tuesday, August 02, 2016, 13:32 chad fisherSouth Hot-CellStandard OperationTM4UC#16UC#16 Removed #17 installed

UCx#16 has been removed from TM$ and UCx#17 installed, high current conductors toqued to 130 in lbs.

 

UCx#16 did not show the standard arcing marks on the 9 pin connector.

In regards to the 9 pin connector on number 17, it was by far the best fitting TM4 target with 9 pin as it required no "fiddling" during installation.

  1300   Wednesday, August 03, 2016, 09:15 chad fisherSouth Hot-CellRepair  Manipulator

East manipulator on the south hot cell is showing signs of eminent wrist/tong cable failure. Some slight slippage was noted yesterday and confirmed by a snapping sound and more slippage tomorrow.

  1314   Wednesday, August 10, 2016, 12:18 chad fisherSouth Hot-CellMaintenance  Anteroom clearing

Black "radio active" materials cabinet has been emptied, items bagged and removed from the anteroom. Cabinet itself has been swiped inside and out and also been removed from the anteroom. Most items have been removed from the anteroom now save some cardboard, rolls of plastic etc.

  1317   Friday, August 12, 2016, 09:58 chad fisherSouth Hot-CellMaintenance  Manipulator Maitenance

Disassembled the master side of the right manipulator this morning to check the wrist cable. The cable on the master side shows no sign of wear or fraying suggesting that the slave side cable may be the item that is wearing. during disassembly of the master I did notice some loose parts that could have been the source of the audible concern but should not have contributed to the slippage felt in the gripper. I will try and schedule Tuesday for entry into the hot cell to address the slave cable.

  1321   Tuesday, August 16, 2016, 11:27 chad fisherSouth Hot-CellMaintenance  South Cell Field Readings

Field readings have been taken at the south hot cell in preparation for entry into the cell to fix manipulator.

Field on contact at aluminum cover is 66 uSv/h, and a pole monitor into the cell through the tool port read 297 uSv/h.
