 Thursday, November 28, 2024, 09:04, Adam Newsome, Hot Cell 1, Repair, Hot Cell turntables not rotating, access hatch not moving
|
It was reported that the hot cell turntables would not rotate and the access hatch could not be operated. The turntables' elevation motion was working
normally, and other cell functions were working.
Upon investigation, after going online with the PLC and checking the interlocks for the turntable, it was determined that motion was being prevented |
Friday, November 29, 2024, 15:23, Adam Newsome, Hot Cell 1, Maintenance, 1000 kg crane: y axis position display not functioning 
|
After a recent power cycle, the y-axis referencing was lost for the 1000 kg crane. The position readout was also incorrect, somewhere on the order of
> 30,000 mm. On 2024-11-29, A. Newsome re-referenced the y-axis. The position readout correctly reset to zero, and both +y and -y motion is functioning
correctly, but the y-axis position readout on the HMI constantly displays 0 and does not change. To be investigated. |

Removal and replacement testing of the stainless VCR lines extending from the HVFT to the piston modules and FE plate is documented in this ELOG.
Exchange of the FE plate water connector lines is documented in a ELOG #79. Exchange of VCR gaskets in the permanent joints is given in ELOG #83.

|
The four water connections on the front end plate of the APTW that will connect to the HTV were tested for replacement with the manipulators:
The pin on these connectors were fairly easy to remove and replace with the old pin detent tool.
The pin detent tool could
also be used to manipulate the water lines while protecting the sealing face.

Wednesday, January 15, 2025, 13:09, Albert Kong, Hot Cell 1, Repair, West turntable festooning pillar and cable damage
|
Some issues were encountered with the turntable controls on the west hot cell, as a result the festooning post for the turntable was damaged. While the
post was out of commission, the turntable was operated without actively monitoring the top of the hot cell and some cables ended up catching on the limit
sensors, causing some slight fraying. The cables were duct-taped to prevent shorting for now but should be inspected and replaced accordingly in the future. |

|
We successfully performed a removal and replacement of a power busbar stabuli connector on the front end plate where the HTV connects to:
The middle-lower connector was tested as the others are more straightforward to work with.
It may be a good idea to use
a 3D printed jig to wedge into the connectors without damaging the flexures/pins.

Today RH (CF and AK) agreed upon using the following style of gaskets for the ARIEL front ends:
All metal rings to be used to avoid plastic retaining rings deteriorating due to radiation and leaving bits stuck in the nuts
Parker style (4 VGR-SS and 8 VGR-SS) gaskets for all VCR joints, except
For the piston module and hanging water line VCR joints (found |

Implemented and tested travel zone restrictions for the 1000kg crane to prevent collision with the manipulator arms. West operator station is currently
occupied so testing was done and confirmed functional for the East operator station. |

|
Two externally mounted jib cranes were installed on the ARIEL hot cell - one on the West side above the tool port, and one on the North side above the
tool port. These cranes are supplied by AC DC Cranes (see attached quote for info). They are 250 kg WLL, 2 m span, powered hoist, manual pivot. They were
mounted using M24x3 x 50mm bolts. |

Tuesday, April 15, 2025, 10:35, Riley Sykes, Hot Cell 1, Repair, North Roxtec Hinge and door.

Repairs were done on the North door that would not close. Due to the weight on the hinge pintle and gudgeon repairs were only possible with a Hydraulic
power pack and ram to lift the door into position. Door is held closed with single Stainless bolt as top bolt hole would no longer line up. If the door
is needed to swing open, recommendation is to use Hydraulic power pack to take some of the weight to facilitate ease. See attached bolt hole photo for |

Tuesday, May 02, 2017, 16:52, Isaac Earle, BL4N, Development, BL4N 35-deg bender stand hardened parts tested
|
Hardness testing was performed on 1 sample each of parts TBP1822 and TBP1823 (part of the 35-deg magnet stand assembly TBP1804), They were
found to be 60-60.5 Rc and 60-61 Rc respectively which is within spec. The alloy used to fabricate these parts was AISI #8620. The testing was performed
by Precision Heat Treat in Surrey who also performed the heat treatment at an earlier date. |

Thursday, June 01, 2017, 15:25, Isaac Earle, BL4N, Development, BL4N 35-deg bender adjustment blocks modified to fit magnet
|
Adjustment blocks were installed on the second dipole bender today (labeled "No. 03" "C15-III-57/15"). The mounting holes on
the magnet were not aligned properly, so modification was required for two of the blocks. The counterbored holes on TBP1809 were slotted 0.10"
vertically, and on TBP1808, 0.06" horizontal slotting was required. A stress analysis was performed to confirm that the blocks are still strong |

Assembly of two complete bender stands was completed on Friday June 2nd
as well as installation of new hardware on the dipole magnets for support, adjustment, and seismic restraint. All parts were installed according
to drawing TBP1804. |

Wednesday, June 28, 2017, 17:37, Isaac Earle, BL4N, Development, BL4N 35-deg bender "No. 1" installed on magnet stand
|
BL4N 35-deg bender magnet "No. 1" has been installed onto the magnet stand with "stand leg" configuration in the Proton Hall
Extension loading bay area. The magnet fit as expected, and with the support legs resting on the ball transfers the magnet position could be easily
adjusted by turning one of the adjuster leg fasteners (with the others loose). After experimenting with position adjustment, the fasteners were torqued |
