 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. |

|
The following work was performed at the T1 cooling package and target between January 18-21, 2016:
- Cuno water filters removed (3), and new filters installed
- Target water solenoid, H.E. secondary side solenoid, and Collimator A solenoids removed and replaced with new 24V DC versions |

Tuesday, April 11, 2017, 17:02, Isaac Earle, Maintenance, Target 2, Cooling, T2 Cooling System MRO
|
The following work has been completed on the T2 cooling package:
- T2 system drained to South TNF holding tank (completed in Jan 2017, water already released)
- Target water and demin. circuit Cuno filters changed |

Tuesday, August 29, 2017, 12:17, Isaac Earle, Maintenance, Target 1, Target, T1-MK1 and T2-MK1 Hansen water fittings replaced
|
The #6 male Hansen fittings for the T1-MK1 and T2-MK1 targets (both currently stored in the target storage pit) were replaced today with new units.
Some of the target assembly Hansen fittings had shown signs of leaking and the internal seals are not easily replaced.
"120V" warning labels were put on the micro-switch IN and OUT limit sensors for the profile monitors on both targets. These are |

Tuesday, April 10, 2018, 11:20, Isaac Earle, Maintenance, Other, Cooling, T1 and T2 cooling package shutdown MRO work
|
The following work was performed on the T1 and T2 cooling packages during the 2018 shutdown:
- T1 and T2 cooling packages both sampled and drained to South TNF holding tank
- Water released after testing and approval from RPG |
|
Friday, April 13, 2018, 14:21, Isaac Earle, Maintenance, Other, Other, M20 beam blocker MRO and T1/T2 final checks
|
The M20 beam blocker main shaft seals were replaced as per the T1/T2 target device maintenance schedule. Both air cylinders were found to be leaking
past the seals, and the blocker would not actuate in the hot cell even with 100psi (max site air) so they were also replaced. With the new cylinders
the blocker actuated smoothly at about 45psi. It is recommended that the air cylinders be replaced every second service (once per 10 years). |
|
Thursday, January 10, 2019, 13:51, Isaac Earle, Maintenance, Target 1, Cooling, T1 and T2 cooling packages inspected
|
The T1 and T2 cooling packages were inspected today while running. No water leaks were observed at either package including the high-active loops
and copper active.
The T1 pump was fairly noisy (video was taken to record the sound). This is the new pump installed in August 2018 (see E-Log #242). |

Tuesday, February 26, 2019, 10:55, Isaac Earle, Maintenance, Target 1, Cooling, T1 and T2 MRO work and solenoid valve change summary
|
The following work was completed between Jan 16 - Feb 19, 2019:
T1 and T2 cooling packages drained to South TNF holding tank, water sampled and tested, released after approval from RPG
T1
resin can swapped
All Cuno filters changed at T1 (3 total)
T1 inlet (T1CSPGIN) and outlet (T1CSPGOUT) pressure gauges replaced |
|
Wednesday, February 05, 2020, 14:53, Isaac Earle, Maintenance, Target 1, Cooling, T1 & T2 cooling package MRO work completed
|
Annual MRO work on the T1 and T2 cooling packages is now complete. The following tasks were performed:
Water from both packages drained to the South TNF holding tank (samples taken)
All Proteus paddle wheels, shafts, and
o-rings replaced (5 each at T1 and T2)
All Cuno filters changed
Archived data for all sensor readbacks inspected. Only |
|
Monday, February 10, 2020, 14:51, Isaac Earle, Maintenance, Other, Other, T1-MK2 target and M9BB moved
|
The T1-MK2 target was moved from the hot cell to Hole #5 in the storage pit. The M9 beam blocker was then moved from the beamline to the
hot cell for MRO work. A field of 14.4mSv/hr was measured at 0.5m from the beam blocker during removal. |
|
Monday, March 23, 2020, 16:13, Isaac Earle, Maintenance, Other, Other, M9 beam blocker MRO completed
|
M9 beam blocker MRO work was completed in the hot cell today. This included replacement of the main shaft seals and replacement of the air cylinders.
Actuation was tested after replacement and the blocker moved smoothly through the full length of travel with approximately 45psi air pressure. It
is ready for transport back to the beamline. |

With the assistance of Maico we changed the paddle wheel, o ring, and shaft in the Collimator A flow meter (Q4) at the T2 package.
Flow meter was wiped clean to ensure o ring surface was clean.
Everything was changed without incident, and ops confirmed that the flow rate is now normal. |
