Gordon Crane technician Tom Kauss finished the replacement of the east side main hoist brake assembly. A new set up is installed. he adjusted gap too
close during first time try. So, the smell appeared when operate the brake. He increased the gap to a proper distance then. It looks like everything works
fine now. Still, The brake need to be tested with 10K lBS load on it. We will do the load test on next Thursday when he come here to replace west side |

|
Anders and I found a low frequency issue(13hz only) on TCS TGHT flow sensor when doing TM4 conditioning. By trouble shooting, We found the module water
lines are good. the restriction cause this problem in on TCS supply or return water lines to TGHT. I switched TGHT lines with MSP water lines. The
wheel frequency on TGHT is 67.0hz which is pretty high. Now, MSP is using the original TGHT water line(flow sensor frequency 13hz). Flow sensors and |

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. |
