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 |

Thursday, July 27, 2017, 08:57, Isaac Earle, Other, Target 2, Cooling, Failed T2CS:SVSEC valves investigation
|
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 |

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. |

|
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. |

The paddle wheels, o-rings, and shafts were changed at the T2 cooling package for the following sensors:
B1A:T2:FGCOLA
T2CS:FGTGT
T2CS:FGDEM
T2CS:FGSEC
T2:FGCOLB
No
major issues were noted. Some residue was observed upon cleaning the sensors. No leaks observed when turning water isolation valves back on. |

|
The 10-pin thermal switch wire, 2-pin steering wire for Q2, and a 1/4" copper tube for remote helium leak check were installed through the
service chase with the power cables and connected to the M9 service stand. Approximately 10m of extra cable (2-pin and 10-pin) was coiled and left
in the cooler section of the service chase after the first sharp bend. The cables and the tubing are currently run as far as the vertical cable tray |

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 |
