Thursday, April 27, 2017, 16:58, Isaac Earle, North Hot-Cell, Development, , , Right side NHC manipulator installed 
|
Installation of the NHC right side manipulator was completed yesterday. The three piece manipulator was assembled in the module assembly
area on the manipulator cart which was then craned through the hatch to the NHC service area (the slave end had to be removed for it to fit through the
hatch). The installation went relatively smoothly except for the second (cold side) piece of lead shielding around the thru tube which would not |

Monday, May 01, 2017, 12:32, David Wang, Crane, Repair, , , TH crane burning smell
|
TH crane burning smell showed again this morning. It appeared after 1-1.5 hours of continuously using during the F308 flasks moving in TH.After a certain
time of using I think the brake gap is reduced because of thermal expansion. The main hoist and brakes work fine still. We knew these brakes gap
are tight especially on west side. So, It is not surprised that this burning smell appeared again. It does not affect the safe of crane use in my view. |

|
The window cover panel has been installed on the hot side of the NHC shielding window according to drawing IRH1638. It was necessary to drill
and tap a hole in the steel frame first to achieve proper grounding for stud welding. The strength of all studs were checked by installing a nut
on the stud tightened against a block up against the steel frame, which was then torqued to a minimum of 10 ft*lbs. For the final installation the |

|
Chad and Anders inspected the test target in the hot cell today. The lid had been previously removed.
The EE looked to have performed well.
A piece of Ta foil was found inside the heat shield. It is not clear if this
has been there during operation or if it entered the heat shield while in the hot cell. The foil has markings which indicate that it has seen heat.

This morning, when I prepare for today's crane check, The crane made a very strong noise without any load during the full speed up motion. I stopped
the crane right away, and noticed that east side of main hoist motor area was smoking . The crane was moved to east end. And, I climbed up to the top,
and found the smoke is coming form brake side, and should be produced by braking. The smell is same as before.Unless other thing is wrong, I think |

|
Isaac and Chad disengaged the slave end of the manipulator and performed a slave removal through the slave removal roof hatch. This is part of investigation
into a 'Z' motion tape that is "rubbing" on its drum on the master side of the manipulator during manual 'Z' retraction of 'Z' extension.
This also was the first test of the concept of removing the manipulator slave through the manipulator hatch that was built into the roof. |

The North Hot Cell inlet ducting assembly was installed today in the target hall at the north end of the NHC roof block. A small section of the
perforated aluminum sheet on the TCS cage had to be trimmed for the assembly to fit (see IMG_0214). At each end of the assembly it was fastened to
the roof structure using a 1/4"-20 tapped hole in the steel roof, and a 1/4"-20 anchor in the north wall of the target hall. The base flange |

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 |
