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. |

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:
Right side OK. |

Thursday, June 07, 2012, 18:08, Isaac Earle, Repair, Target 1, Target, Hot Cell Manipulator Broken Tape
|
A tape snapped on the west side manipulator today while working on the T1-MK2 target repair. The tape travels through to the slave end, so
unfortunately the manipulator will need to be removed from the hot cell for repair. This is the same manipulator that was just out for a broken cable
repair, and I suspect that the tape was accidentally kinked or dislodged from a pulley when the manipulator was disassembled. |

Monday, April 23, 2012, 09:55, Isaac Earle, Repair, Target 1, Target, Hot Cell Manipulator Broken Cable
|
While working on the leak repair of the T1-MK2 target in the hot cell on Friday April 20th, a cable snapped on the slave end of the right side
manipulator. It is suspected to be the 'Y' shaped cable assembly that actuates the grippers when the lever is pulled on the master end.
The target repair job cannot continue until the manipulator is repaired. The repair job may take up to a full week, and will require space |

Wednesday, July 06, 2022, 12:49, Adam Newsome, Repair, Other, Hot Cell, Hot Cell - Helium wand tubing broken
|
The tubing for the helium wand inside the hot cell is broken and needs to be replaced. More tubing has been ordered and the job will be completed in
the coming weeks. |

Wednesday, July 06, 2022, 12:49, Matthew Gareau, Repair, Other, Other, Helium line damage, and hotcell window oil leaking
|
Today myself and Adam Newsome started the leak detection steps for a target exchange and notice that the Helium line was not connected/broken from inside
the hotcell.
A new line will need to be installed and the line attached to the helium wand. |

|
On January 15th, when attempting to move the T2 target from the beam line to the hot cell, the latch mechanism on the flask did not actuate and
the target could not be lifted from the beam line.
On January 16th the flask was placed on blocks (IMG_0818) (while remaining attached to the crane) in the RH hot cell lab for inspection. The |

Wednesday, March 28, 2018, 10:12, Isaac Earle, Standard Operation, Other, Other, Five waste pails moved to East Vault Tunnel for storage
|
Five 5 gallon metal pails with active waste were moved from the Warm Cell to the Cyclotron East Vault Tunnel today for long term storage.
The pails were labeled with radioactive item tags and storage item numbers (1442 through 1446). The pails contain used resin from T1, T2, and STF,
as well as one pail with active metal parts. |

Monday, November 17, 2014, 10:14, Isaac Earle, Development, Target 1, Active Sump, Filter Installed Downstream of RH HC Lab Active Sump
|
A filter housing and filter were installed by Dan McDonald on November 14 in the piping section between the Remote Handling Hot Cell Lab active sump
and the city sewer drain as shown in the attached picture. The purpose of the new filter is to prevent pieces of active material from being released
to the drain when the sump is pumped out. If small pieces of active material enter the sump they may sink to the bottom, and not be captured in a |

Tuesday, January 17, 2023, 13:46, Adam Newsome, Maintenance, Other, Active Sump, Filter Change: RH Active Sump and BL1A Holding Tank Drain Output
|
The CUNO filters were changed 2023-01-17 for:
BL1A Holding Tank drain output, adjacent to the pump
RH Active Sump, adjacent to the V2 valve
Both of
these filters are in-line with the drainage lines from the BL1A holding tank to the active sump. It was suspected that they have not been changed in many |

The three failed T2 cooling system secondary side solenoid valves were tested yesterday to try to determine the problem. The test steps are
detailed below:
New spare valve (NSV) produced audible "click" and valve was seen to physically open when 24V DC driving voltage was applied

Thursday, October 06, 2016, 12:16, Isaac Earle, Development, Target 1, Controls, Expansion Tank High Level Warning Added
|
An expansion tank high level warning has been added to the T1/T2 control system under Work Request #4011. The purpose for this new warning
is to alert staff of an unexpected water increase in the unlikely scenario that a leak develops in the heat exchanger between the two fluids and CuALCW
on the secondary side enters the target water system. The new thresholds for high level warn, low level warn, and low level trip have been set at |

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, September 09, 2013, 16:13, Isaac Earle, Repair, Target 2, Cooling, Drop in T2 Cooling Package Water Level
|
On September 9th in the morning Ron Kuramoto noticed that the T2 cooling package expansion tank level was reading NOT OK for the warning level.
Looking at XSTRIP showed that the warning level tripped at approximately 1:50am on September 8th. The tank was refilled at 4pm on September
9th to the usual level (1/2" above the nut on the trip level float). The expansion tank level will be checked tomorrow and periodically throughout |

2018 Cyclotron lid up problem. Station #9 was found to have the motor wires along the beam plain had damaged wire insulation. There were
bare wires in the conduit resulting in the wires shorting out. The wires were repaired with a quick short replacement. Lid went up for in tank work. After
lid down the problem was investigated. We checked the radiation levels at all of the stations to come up with a plan to determine witch of |

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 |

Friday, April 12, 2013, 13:28, Isaac Earle, Standard Operation, Target 1, Cooling, Cooling Packages Leak Tight
|
The T1 and T2 expansion tanks were filled on Monday April 8th. There was no change in the level when inspected today (April 12th). Visual
inspection of the packages also found no leaks. |
