|
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. |

Monday, December 22, 2014, 14:21, Isaac Earle, 100KW Beam Dump, Development, Water System Leak Checked
|
This morning Bill Richert pressurized the beam dump water cooling system with 30psi air and held for 2 hours. He reported no change in pressure
which indicates the flexible hose connections installed last week are leak tight. |

Wednesday, December 03, 2014, 10:36, Isaac Earle, 100KW Beam Dump, Development, Upper half of BD water blocks installed; Bypass loops installed
|
On December 2 the upper half of the RH water blocks were installed (4 total) using a 0.030" thick 6061-T6 Al shim torqued to 60ft*lbs as was tested
in Document-114260.
Bypass loops for testing the cooling system piping were installed as shown in the attached photo. |

Tuesday, December 16, 2014, 16:36, Isaac Earle, 100KW Beam Dump, Development, Upper Pb Shield and Water Hoses Installed
|
The upper lead shield was installed this morning. Also the water hoses for lower lead shield, beam dump, and upper lead shield were all installed.
See attached photos and hose installation information PDF. |

Wednesday, March 13, 2019, 16:14, Isaac Earle, 100KW Beam Dump, Development, Testing EHD water leak detectors 9x
|
The following work was completed today on the EHD water leak sensors:
Mike Vogel installed a 1/4" copper tube which leads from the east side of the EHDT shielding down to the catch tray below the water
blocks. This can be used for future testing of the in-tray sensors without removing the shield blocks. It may also be possible to test the |

Thursday, October 17, 2024, 11:34, Albert Kong, Hot Cell 1, Development, Tarping completed on hot cell roof
|
Two tarps were installed above the hot cell roof to protect against concrete dust while testing in the hot cell.
Zip ties were used to hook the tarp onto tubing brackets on the back wall. |

Wednesday, April 24, 2024, 09:17, Adam Newsome, T-Hall Crane, Repair, Target Hall Crane: VFD DC bus undervoltage fault [root cause: encoder board failure on 900VFD]
|
On 2024-04-22 around 3:30 pm it was discovered that the crane's main hoist was in a faulted state. The operator (Adam Newsome) experienced the fault
after performing a safety reset and attempting to lower the hoist. There were no visible signs of any issues, mechanically. This fault had not been previously
reported by any other crane operators. The crane was previously unused, sitting idle. Note: the auxiliary hoists appeared to function normally. |

Wednesday, February 14, 2024, 09:02, Adam Newsome, T-Hall Crane, Maintenance, Target Hall Crane: Trolley Encoder Homing
|
The main trolley's E/W motion was observed to be slowed on 2024-02-13.
Upon investigation, the following faults were present:
- 200. Rotating Hook Velocity Difference between SSI Encoder and Drive Speed Feedback |

Wednesday, April 26, 2023, 16:06, Adam Newsome, T-Hall Crane, Maintenance, Target Hall Crane - Hoist Wire Wrapping
|
It was observed recently that the main hoist's wires seemed skewed, and there was occasionally some noise heard when raising and lowering the hook block.
It was suspected that this was due to wires having jumped in their tracks at some point. This is typically caused by side loading. It is possible that
wire wrap skew occurred during the incident outlined in e-log 46. |

Friday, February 06, 2015, 13:32, Isaac Earle, 100KW Beam Dump, Development, TEL5079 Hose Modification
|
When the EHDT shielding service stand shield plug was installed in January it was found that the Beam Dump Outlet Hose (TEL5079) was interfering with
the plug. The following remedial action was taken:
- Upper lead water blocks disconnected and upper lead shield removed w/ hose assemblies and upper half of water blocks attached |

Tuesday, September 10, 2024, 13:03, Adam Newsome, Hot Cell 1, Development, Spacer flange installation
|
The spacer flanges were installed on both turntables today.
See photos and information in the following DocuShare Collection: Collection-39816
Important note: the fitment was quite tight due to interference with universal joints and grease nipples. The flanges were still able to be installed |

Thursday, October 10, 2024, 12:22, Adam Newsome, Hot Cell 1, Standard Operation, Safety Walkaround Complete - Hot Cell area
|
A safety walkaround was completed for the ARIEL Hot Cell area.
The resulting spreadsheet can be found on DocuShare as Document-242733.
No major deficiencies identified. |

Monday, May 30, 2022, 12:58, Adam Newsome, T-Hall Crane, Development, Reversion of South position limit to OEM value
|
The position limit modification described in e-log 49 has been reverted. Currently the South soft limit is set back to 0.36m.
The limit was tested and confirmed (craned stopped at 0.33m position which is acceptable due to coasting). The entire bridge range of motion was
checked to ensure there were no adverse effects - all is OK. The South bumpers need to be reinstalled - this will take place in the coming weeks. |

Thursday, April 07, 2016, 11:25, Isaac Earle, 100KW Beam Dump, Development, Result of VCR Gasket Corrosion Test
|
In August 2014 gasket corrosion tests were prepared by placing a 1" Swagelok VCR gasket in a 500mL beaker with de-ionized water and a 1"x3/4"x1/8"
piece of 6061 aluminum. Tests were prepared for a silver plated 316L SS gasket (Swagelok PN: SS-16-VCR-2), a silver plated nickel gasket (PN: NI-16-VCR-2),
and a TRIUMF made 0.060" thick 6061 Al gasket. The top of the beakers were sealed, and they were left to sit until March 2016. |

Thursday, February 13, 2020, 08:51, Adam Newsome, T-Hall Crane, Standard Operation, Remote mode door limit switch bypass
|
The non-existent safety limit switch for the target hall door which prevents remote motion has been bypassed in the crane PLC control panel to allow
for remote operation of the crane. This will be un-bypassed when a switch is installed. Specifically, a jumper was placed from terminal 18001 to 20121
and 20141 which will enable the hall lock safety relays 2012SR and 2014SR. The crane is currently operational in both local and remote mode. |

Wednesday, June 24, 2015, 15:19, Isaac Earle, 100KW Beam Dump, Development, Remainder of BD Shielding Installed
|
The location of the already installed blocks including the TSH0392 protruding lift bails were remeasured, and it was found that modification of the Standard
Lock-Block Flat Top block was not required. A Standard Lock-Block Flat Top block was installed in the place of TSH0487 in drawing TSH0372, and the
remainder of the blocks on top were installed. It was a tight fit for the lower two Half Height Lock-Blocks, but future removal of the BD shielding |

Thursday, May 07, 2015, 16:23, Isaac Earle, 100KW Beam Dump, Development, RH Clamp Installed with Used Seal
|
The remote handling 4" marman flange clamp was reinstalled today with a used seal. It is "Clamp B" as tested in Document-114623.
The purpose of installing the clamp now is to prepare for the upcoming remote handling test of the vacuum joint and one of the water blocks.
During installation it was found that it will be necessary to manipulate both the BD flange and the EHDT beam pipe flange to have the seal mated |
