|
On April 18, 2017, an investigation was initiated to determine the cause of the ARIEL Target Hall overhead crane faults that occurred while attempting to
perform remote lifting operations in Test Mode on a 8.6 tonne SEG block (see E-Log #30). Hugo Lapointe (Automation Technician, REEL-COH) requested pictures
of the HIM (Human Interface Module) displays, located inside the electrical panels in the crane control room, immediately after a fault to assist with |

Wednesday, April 12, 2017, 10:52, Jason Kapalka, T-Hall Crane, Repair, ARIEL Target Hall crane oil leaks & inspection plan
|
On March 29, 2017, a 9 tonne load was transferred in the ARIEL Target Hall with the overhead crane (TRIUMF crane #44). On April 3, 2017, several drops of
green oil were observed on the floor and hookblock directly beneath the single equalizing sheave. The Remote Handling department millwrights were notified
and an inspection of the crane using a man-lift was performed to verify the source of the oil leak. Upon inspection, it was confirmed that the green oil |

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. |

|
Two small (approx. 5 cm across) puddles of green fluid were discovered on the floor, directly below the crane trolley. The hook block was lowered
and inspected. No fluid found on hook block.
The plant group (Neil Wong) was notified and asked to schedule an inspection when the maintenance crew is on site to inspect the ISAC target hall |

Tuesday, November 03, 2015, 13:15, Isaac Earle, 100KW Beam Dump, Development, Initial tests of beam dump water system controls
|
During the maintenance period today the E-Hall tunnel was accessed to begin controls tests on the beam dump water system and initial fill of the system.
This work was done by Bill Richert and Dave Morris while I observed. Before work began I verified that pressure relief valves were installed
as per the P&ID (TEL5104 Rev A) - they have been installed but the exhaust ports from the valves have not yet been routed to the active drain. They |

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 |
