 Friday, September 23, 2022, 10:51, Matthew Gareau, Standard Operation, Target 2, Target, Target T2-MK2 moved to storage pit 
|
The T2-MK2 target was transported from the east hot cell to the storage pit at position 3.
As was noted in the past, position 3 is difficult to align. The flask alignment pins prevent the flask from positioning in the correct location,
and it is required to have the flask just above the pins to ensure that the pins did not restrict the flask movement. |

Monday, January 16, 2023, 09:54, Adam Newsome, Standard Operation, Other, Cooling, T1 and T2 - Cooling Package Drained
|
On Jan. 13, the T1 and T2 cooling package water reservoirs were drained to the BL1A holding tank. Water samples were obtained for each system and provided
to RPG for analysis.
Prior to starting draining, the BL1A holding tank water level was approximately 330L. After draining, the water level was approximately 550L (checked |

On May 31, the low active water in BL1A was turned off briefly and upon re-starting, the flow to the T1 heat exchanger was very close to the reported
warn limit (~6 gpm).

See Cyclotron fault 16553.
"B1A:T2CS:FGTGT readback is toggling at the warn limit of 3.0 GPM and over the last week has started crossing over the trip threshold of 2.8
GPM, tripping off the water package. Initial Action Taken: 1A is scheduled to take beam on December 13." |

Wednesday, January 10, 2024, 12:25, Albert Kong, Standard Operation, Other, Cooling, T1/T2 cooling packages drained
|
Jan 10, 2024:
The cooling packages for T1/T2 was drained this morning. ~150 L from each of the cooling package reservoirs + expansion tank was drained to the
BL1A holding tank. The holding tank held ~400 L initially and is therefore now filled to ~700 L (out of a 800 L capacity). We will likely drain the holding |

Wednesday, January 10, 2024, 12:47, Albert Kong, Standard Operation, Target 1, Target, T1 target ladder exchange (T1-MK1 to hot cell roof, T1-MK2 from pit to station)
|
T1-MK1 was moved from the target station to the hot cell roof.
Radiation surveys report 140 mSv/hr at 0.5m for the bare T1-MK1 target ladder.
On the hot cell roof, fields are 220uSv/h at 0.5m. |

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. |

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, |

|
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). |

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. |

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 |

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. |

|
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 |

|
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). |

|
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 |

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 |

|
While wrapping up vacuum seal bearing replacement on the M20 beam blocker I found a piece of hard black material approximately 3x1x1cm on top of
the hot cell turntable. Checked for contamination and found 480,000cpm on the Ludlum 44-2 probe, and off scale on the pancake monitor. This
piece fell from the transport flask when it was opened above the hot cell after picking up the M20 beam blocker. Upon further inspection, more pieces |

Wednesday, January 18, 2012, 12:01, Isaac Earle, Repair, Target 2, Target, Broken M20BB Bearing Removed, New Design Complete
|
The broken M20 beam blocker plastic shaft bearing was removed. Measurements of the bearing as well as the shielding disc (for which drawings
can't be found) were taken inside the hot cell and a brass replacement bearing has been designed based on these measurements.
Photos of the removed bearing, measured dimensions of bearing and shielding disc, and a PDF drawing of the new design are attached. |
