T2 target water leak was identified earlier this morning.
Isaac Earle, Ron Kuramoto and Keith Ng co-ordinated Meson Hall blocks removal and target flask transport.
Target assembly was removed from B/L approximately 5pm. |

|
The suck tube vessel was drained, rinsed, and transported to the active sink area in the Meson Hall Hot Cell Lab. There are no longer high fields
from the suck tube and it is ready for future use. The filter, tubing, and flange used for filtering the active water were removed and bagged and
are currently stored in the south-east corner of the warm cell. This bag measured up to 12mSv/hr on contact. There are small black particles |

Monday, January 20, 2014, 11:51, Isaac Earle, Repair, Target 2, Water Leak, Water Leak from Meson Hall Mezzanine Near T2
|
A water leak developed this morning from a city water supply line at a hose connection near the T2 expansion tank. Water was observed to
be dripping off the mezzanine onto the plastic sheet covering the T2 cooling package. The leak has been stopped and the leaky fitting is being repaired
by Carston Frasden. |

Wednesday, January 22, 2014, 15:41, Isaac Earle, Standard Operation, Target 2, Water Leak, Water Drained From Suck Tube Released
|
After approval from RPG, the water drained from the suck tube, which was stored in a bucket in the RH lab active sink area, was released to the
active drain. Even after rinsing, the bucket still had a slight field from the base, so it has been labelled and will be kept in the active sink
area. |

Tuesday, March 25, 2014, 18:24, Isaac Earle, Development, Target 2, Water Leak, Water Detecting Sensor Install at T1 & T2 9x
|
Water detecting strips were installed around the T1 and T2 areas today with Doug Preddy and contractors from SMT Research. Four sensors were installed
at various locations on each cooling package. Four sensors were installed on the top surface of the T2 monolith. In addition, four sensors
were routed for future installation at the T1 monolith (it is currently covered by blocks and requires cleaning and painting before sensor installation). |

|
On Sep. 3rd during the 6 hr maintenance day, Doug Preddy
& I went into the 1A tunnel under “controlled access” to investigate a water leak that triggered the Water Detection Sensors. It was also noticed that the Cu-ALCW tank level was losing water. |

On Oct 7th,
during the Mini Shutdown, the T2 cooling package was uncovered to investigate the Cu-ALCW water leak dripping into the 1A Tunnel. |

Monday, December 22, 2014, 14:31, Isaac Earle, Maintenance, Target 2, Water Leak, Drop in T2 water level
|
This morning at 5:30am the T2 cooling package expansion tank switched to WARNING LEVEL NOT OK. There was no change in BL1A vacuum at this time.
The change in level was confirmed by inspecting the water level visually. Operators suggested it may have happened because the cyclotron was
shut off and the temperature of all water systems dropped, however T1 did not experience a noticeable change in level, so I do not think this is the cause. |

Monday, January 05, 2015, 15:08, Isaac Earle, Standard Operation, Target 2, Water Leak, Cooling Packages Re-Started; Suspect External Water Leak at T2 Package
|
Pumping was restored to 1A today by Vacuum Group and the beam line returned to normal vacuum levels. Both cooling packages were started with no
change in vacuum (no water leaks inside the vacuum volume). The T2 package was left on for approximately 1 minute, and then the expansion tank level
was checked. Approximately 1cm of water was lost. The T2 package was turned off, and will remain off until the package can be inspected later |

Wednesday, January 07, 2015, 17:27, Isaac Earle, Repair, Target 2, Water Leak, Water Leaks at T2 Cooling Package
|
The T2 cooling package was visually inspected today after blocks were removed. With the cooling package off the following leaks were observed:
- Collimator A return line ball valve: ~ 2 drops / second
- Collimator B return line ball valve: ~ 1 drop / 3 seconds |

Thursday, August 27, 2015, 15:47, Isaac Earle, Repair, Other, Water Leak, Warm Cell Water Window Seal Replacement Update
|
Since the previous E-Log the following tasks have been completed:
- Panel spacer rods installed at 4 locations in each tank (two top, two bottom at approximately 1/3 and 2/3 the way across)
- Spacer rods expanded only slightly to begin compressing the rubber window spacers while still leaving at least a 8mm gap between window and frame |

Monday, September 28, 2015, 11:33, Isaac Earle, Repair, Other, Water Leak, Warm Cell Water Window Repair Complete
|
The warm cell water window tanks were filled on September 17 after 2 weeks of curing time. A water leak was found coming from the seals of a plastic
pipe joining the two tanks near the top. This was repaired using rubber gaskets and quick cure caulking. The tank was refilled on September
18 and no longer leaked from that location. The sand filter was backflushed with the water exhausted to the grass area outside the hot cell lab until |

Thursday, January 12, 2023, 10:36, Adam Newsome, Maintenance, Target 1, Water Leak, T1 and T2 - Cooling Package Water Leaks - Ball Valves
|
Upon uncovering the T1 and T2 areas to prepare for regular cooling package maintenance, it was discovered that multiple ball valves were leaking. Primarily
the Swagelok SS-45S12 parts, but some SS-45S8 parts have failed as well. There were small puddles of water underneath many of the valves. It appears that
the leak is due to a compromised seal. It is suspected that these parts failed from radiation exposure. They have PTFE packing material which is highly |

Friday, February 17, 2023, 14:36, Albert Kong, Repair, Other, Water Leak, T1/T2 Water Cooling Package Ball Valve Replacement
|
5 and 3 Swagelok ball valves were replaced from the T1 and T2 cooling packages respectively.
These are compression fit valves, 1/2" or 3/4" size.
1 valve in T2 was replaced previously, bringing the total # of replaced valves in T2 to 4. |

A trial run of remote removal of the UCN target was performed using the shielded target cask (TTA0335) developed in 2020. The work took place between
Feb 9 - 17 under work permit C2021-02-09-1.
The procedure in work instruction Document-187117 R1 was followed. Draining and purging of the water system as well as venting of helium from the |

Replaced T1-MK1 target ladder with the new ladder design which has an integrated upper slide plate (2 less sealing locations) and no c-seal grooves.
C-seals replaced with aliuminum delta seals.Transfered all target cassettes to new ladder in the same positions. Performed helium leak check
at interface with bellows flanges and all cassette locations. No leaks detected. |
