Monday, July 10, 2017, 09:09, Dan McDonald, North Hot-Cell, Repair, , , manipulator cart repair 
|
A hydraulic leak was found on the manipulator install and repair cart, upon further investigation the cause was a faulty cylinder. Once the
cylinder was removed and disassembled the inner bore was found to be scored beyond repair. Another point of interest was that the rod was painted to the
point that when retracted it compromised the rod seal causing the cylinder to leak. attached are photos outlining the issues. new cylinders are being sourced |

Thursday, July 06, 2017, 14:23, Isaac Earle, North Hot-Cell, Repair, , , Slave side Z motion tape snapped on NHC right side manipulator
|
The NHC right side manipulator was evaluated today to check if operation was normal through all ranges of motion. The manipulator was first moved
through usual motions without the electric motion drives: the feel was fairly normal, a sound could be heard from the master side Z motion tapes rubbing
on the sides of the pulleys, this problem had been identified a few weeks ago however it was significantly reduced since the master side upper and lower |

Wednesday, July 05, 2017, 15:36, Isaac Earle, North Hot-Cell, Development, , , NHC and SHC nuclear ventilation flow sensors installed
|
Installation of new flow sensors and transmitters for the NHC and SHC duct lines was completed in the target hall today. The sensors are
Dwyer DS-300-8 in-line sensors for 8" pipe; The transmitters are Dwyer MS0121 magnesense differential transmitters with 4-20mA output. The transmitters
will be wired to the new PLC control system when the upgrade is done. |

|
The target was inspected by Chad and Anders. Photos are available on DocuShare.
It was noticed that the target tube heater terminals had lifted up from the insulator on the target assembly as seen in this Photo.
This has later been detemined to be from the assembly, where additional clearance was required and achieved by installing |

|
The North Hot Cell module support flange (IRH1152D) was installed on June 21, 2017 using 1/8" rubber sheet as a sealing gasket. The
rubber was glued at the seams with Loctite 495 instant adhesive. Cameras with all required wiring and connectors were installed on the mounting bars
(IGN0325D) and then aligned to provide the same view as at other module installation locations in the target hall. A cable with 5 video signals, |

|
Gordon crane technician Peter came in today and checked TH crane. Maico and I were there with him. What he found is that brake gap on both side of
main hoist decreased after months of using. The solution is to lock the automatic self adjustment system so the gap will be fixed there. Each year
during annual inspection, they will adjust the gap manually. After he locked both side of device, I tested the crane up and down couple of times. The |
