 Friday, January 10, 2025, 18:36, Albert Kong, Standard Operation, Other, Cooling, T1/T2 cooling packages drained 
|
The T1 and T2 cooling packages were drained starting at 14:36, by 14:48 both expansion tanks had dried, meaning the draining rate for both tanks were
~80L/hr, generally it will only take 2 hours to fully drain the system.
Tritium samples were collected after allowing the system to drain for ~5 minutes to clear out water in the drain lines and actually collect samples |

|
The following maintenance tasks were completed on 2024-11-29 by A. Newsome, A. Kong, A. Tam, M. Dalla Valle:
Warm cell right window water level topup... the water level was a couple inches lower from the top. Using a tube connected to the nearby
sink, the level was topped up fully. See attached before/after picture.
Hot cell oil level checks:

Monday, September 09, 2024, 16:31, Albert Kong, Standard Operation, Other, Active Sump, Active Sump High Level Sensor Testing
|
The active sump high level sensor was tested and correctly alarmed locally. However the alarm in the MHESA RCR lab did not make any sound and no notification
was recieved at the main control room. After some investigation, it is believed that the RCR lab alarm 'had already produced a notification at the control
room and so no new notification was produced by testing the remote handling sump. Alternatively, the RCR sump alarm may have been silenced in the control |

Monday, September 09, 2024, 09:39, Albert Kong, Other, Target 2, Cooling, B1A:T2CS:FGSEC:RDFLOW noisy, CYCLOTRON Fault 17321
|
Secondary flow sensor B1A:T2CS:FGSEC:RDFLOW on the T2 cooling station suddenly became very noisy at around 11 pm, 01 September 2024.
The sensor reading would fluctuate from 0-150 gpm which is beyond typical noise levels for these sensors (~2gpm).
The noise spontaneously ended at around 4 am, 05 September 2024. |

Thursday, August 22, 2024, 15:16, Adam Newsome, Standard Operation, Other, Active Sump, Active sump filled ~600L with grey water from RCR1 sump replacement
|
During a replacement of the RCR1 active sump (mechanical services group), approximately 600L of non-active grey water was released into the RH active
sump. At this time, this should be all of the water in the RH sump (approximately 600L total). |

Tuesday, August 06, 2024, 11:35, Albert Kong, Standard Operation, Other, BL1A Holding Tank, BL1A and RH Active Sump Draining
|
The RH active sump was drained (over Jul 31-Aug 01), in total approximately 5500 L of water was sent to city sewage.
We also tried to divert water from the BL1A holding tank to the active sump, and learned that we cannot run back-flow through the sump pump. The
valving configuration used here was V10, V1, SV1, V6 open - V2, V3 closed. (Note solenoid valve SV1 does not serve a purpose and energizing/powering-down |

Thursday, May 23, 2024, 17:10, Albert Kong, Standard Operation, Target 1, Target, T1-MK1 Target Exchange (+ leak fix, service panel changes, coupler exchange) 36x
|
On May 23, 2024 two sets of plugs from position 1 and 3 and a 12mm Be target from position 5 (serial #109) was removed from T1-MK1 in the Meson Hall
remote handling hot cell.
The plugs and spent target are kept in the secondary hot cell (East) on the lift table for future beamspot imaging and to cool down prior to disposal. |

Tuesday, May 07, 2024, 13:21, Albert Kong, Repair, Target 2, Cooling, T2 Cooling System Expansion Tank Ultrasonic Level Sensor Repair
|
At ~8am on May 06, the expansion tank level sensor for the T2 cooling system suddenly became noisy.
Cyclotron fault ref: 16915
Approximately 11:00 am today, the noisy sensor was replaced with a spare, upon which it was learned that the spare sensor is broken (registers |

|
As of 2024-04-03, the BL1A Holding Tank water level is approximately 580L. It is recommended to drain the tank prior to the start of the operating year.

Thursday, February 15, 2024, 14:53, Albert Kong, Maintenance, Target 2, Air amplifiers, T2 Lower Air Amplifier Maintenance/Rebuild
|
The lower amplifier for the T2 target station air supply was removed for teardown, inspection, and rebuild.
The goal of this operation is to understand wear development in the air amplifier over ~13 years of operation, and potentially determine a recommeded
service interval. |

Feb 1 2024
Hand Pump observed to be losing pressure at full extension of cylinder, seals likely blown. Due to Enerpac P84 being an obsolete model, a newer
model hand pump was ordered. |

Thursday, February 01, 2024, 11:16, Albert Kong, Standard Operation, Other, Cooling, Spent resin can rinse, purge, and drying
|
The recently removed resin can from the T2 target station was rinsed with city water and flushed with compressed air for 1 cycle.
We will run it through a few more cycles before proceeding with drying under the fume extractor, at which point this ELOG will be updated.
UPDATE (Feb 08, 2024): The T2 resin can underwent 3 more air cycles. Today it was moved under the fume extractor with the lid cracked open and |

Thursday, February 01, 2024, 11:14, Albert Kong, Standard Operation, Target 1, Hot Cell, T1-MK1 Flush and Purge on Hot Cell
|
The recently removed T1-MK1 target ladder was flushed with city water for ~30s at all target positions. It was then purged with compressed air at ~5
psi for ~1 minute at all target positions. We then left the target ladder in pos5 to fully extend the bellows and allow it to dry overnight.
This ELOG will be updated as we progress with work done to dry the target ladder and eventually exchange the spent targets. |

|
The following tasks were completed:
Yesterday (Jan 18), the T1/T2 cooling packages were inspected for leaks and some moisture was found underneath the CUNO filters behind
the resin cans on both T1/T2. It was determined that the source of the leak was a loose fitting on the drain valves of the CUNO filter housing (see photo). |

Monday, January 15, 2024, 16:47, Albert Kong, Standard Operation, Other, Cooling, T1/T2 Cooling Pkg. Prep for Refill + Leak Check At Pressure 7x
|
The following tasks were completed in preparation of re-filling the T1 and T2 cooling packages:
All valves were returned to the 'open' configuration (note, compressed air to collimators at T1 is to remain closed - rotating collimator
no longer in use || also note, odd handle configuration at T1 panel when all valves are open - see attached).
Leaks from valves were checked, |

Monday, January 15, 2024, 16:36, Albert Kong, Standard Operation, Target 2, Cooling, T2 Resin Flask Exchange
|
The resin flask on the T2 cooling package was exchanged today (new resin can prepped in the morning).
The newly installed resin flask was placed slightly off-set from the marking on the platform to ensure that the braided hose will clear the blocks
when replaced at the end of shutdown. |
