Blocks were moved from ITW to ITE by Frank and David. ITE water flow to dump was re-opened (ITW remains open). A dose badge was installed in the operation storage area. Dose rates were measured to ~10 mSv/h at 1pm. Beam went off approximately 8:30am (with a short period of 2uA ending at 11am).

 The following tests have been successfully completed using the NHC manipulators:

  • Ventilation pre-filter (mounted on the NHC/TCS partition wall) removed and re-installed using the manipulators
  • Electrical plugs (two total) for operator-level LED lighting located on east wall of cell interior plugged in, and un-plugged using the manipulators
  • Electrical plug inserted into and removed from each of the 120V outlets (four total) located in front of the viewing window using the manipulators
  • All diagnostic service connections removed and reinstalled using the manipulators (six total, see IRH1765)
  • All Staubli air and gas connections removed and reinstalled using the manipulators (five total, see IRH1749)

 

These tests were performed at various different times over the last several months by Isaac Earle and/or Chad Fisher.

  1826   Monday, November 26, 2018, 12:19 chad fisherNorth Hot-CellRepair  East Manipulator

In preparation for removing the slave for replacement I discovered that the timing screw in the handle cable drum (master side) had been left threaded into the pulley...it should have been completely removed. It was bent from hitting on a casting inside the mater arm which most likely contributed to the hopped pulleys on the slave side. After removing this timing screw I entered the north hot cell and replaced the hopped cable back onto its pulley and Isaac tested the motions that previous caused the hopped cables. These tasks were repeated 4 times without any issues. Also of note is a missing setscrew in the tong cable pulley pin and a somewhat loose tape on the slave, also the tape shows signs of a crimp/bend. Upon further inspection and comparison with the other slaves I also found that one of the "lock-down" fittings tying the Z motion tape drum to the corresponding gear is completely missing. See pictures attached.

To satisfy RS 101 from the NHC requirements specification (Document-131915) Tomislav Hurskovec was consulted regarding high voltage safety.  After a verbal discussion on various aspects of the NHC design he confirmed that the design satisfies high voltage safety concerns.

A copy of his confirmation e-mail is attached in PDF format.

Paddle wheel signal was tripping proton beam in ITW. Valved off ITE dump to divert flow to ITW. Field around valve was about 600 uSv/h

  1821   Wednesday, November 14, 2018, 16:10 Anders MjosITWRepairTM2UC#25ITW:FC5 safety signal troubleshooting

Measured resistance on safety limit switches for FC5 on Exit Module 2. Determined that the in connected signal did not work (shows not connected irregardless of FC position). Confirmed proper operation of the OUT limit. See attachment for details. The Harp 5 x and y signal connectors were checked and reconnected.
