|
Installation, wiring, and commissioning of the high temperature limit switches for the T1 and T2 cooling packages was completed today as part of SAS
project SASP0120. The relay output from the switches was wired in series with the Central Safety System signals for T1 and T2 (cable number 13250
and 12250 respectively) in break-out panel #2 on the Meson Hall south mezzanine. There were already 3 other circuits wired in series with each signal |

|
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. |

|
The T1-MK1 target protect and profile monitor electronics were 'blip' tested by Bill Rawnsley on April 5, 2013. The response from the profile monitor
appeared normal, however the protect monitor response was very weak. After various debugging it was found that the 9 pin connector on the target
on the vacuum side of the vacuum flange had become disconnected from the vacuum flange feed-through. It is suspected that this happened while changing |
Tuesday, March 26, 2013, 10:55, Isaac Earle, Maintenance, Target 1, Target, T1-MK1 Re-wiring and MRO Complete

|
- T2-MK2 target moved from beamline to hot cell (Feb 4th)
- Steel target support shield installed as well as ~3 layers of lead blankets. Even with this extra shielding fields in the working area were
as high as 800µSv/hr. |

|
- The new tube array was picked up from Kaltech on Feb 8th (observed vessel holding 60psi on hydro test at their shop)
- Vacuum leak checked at TRIUMF: would not pump down
- Applied 20psi air, and found leaks on both tube sheets using Snoop |

Tuesday, February 05, 2013, 09:50, Isaac Earle, Maintenance, Target 2, Target, T2-MK2 target moved from beam line to hot cell
|
The T2-MK2 target was transported from the beam line to the RH hot cell. The profile monitor was secured in the 'in' position before lifting the
target, as it is better protected in this configuration. This procedure will be used for all future target moves to reduce the risk of damage to
the monitor. |

Friday Jan 25:
- Both sides of heat exchanger drained, disconnected, and capped
- Heat exchanger transported to warm cell (field from H.E. approximately 15 |

Monday, January 21, 2013, 16:18, Isaac Earle, Standard Operation, Target 2, Target, T2 Cooling Package Water Released
|
The T2 cooling package water was drained to the BL1A active sump, refilled, cycled, and drained again. Samples of T2 cooling package active water
was given to RPG, tested, and approved for release.
On January 21 at approximately 4pm the full volume of the sump (280L) was released to the city sewer. |

Monday, January 21, 2013, 11:57, Isaac Earle, Repair, Target 2, Target, Flask Repair
|
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 |

|
The T2-MK1 target (spare T2 target) was transported from the hot cell to the storage pit today.
While the flask was being aligned to the storage pit locating pins, the base of the flask bumped the top of one of the alignment pins. This
was caused by a slight misalignment between the flask locating hole and the alignment pin at the moment when the flask was lowered. This caused the |

Friday, January 11, 2013, 15:48, Isaac Earle, Standard Operation, Target 1, Target, BL1A Tunnel Accessed
|
The BL1A tunnel was accessed to drain and sample T2 cooling package water. A puddle of water was noticed in the South TNF area around the
drain by the boot-box. No water was found in the BL1A tunnel. Photos attached. |

Thursday, November 22, 2012, 17:22, Isaac Earle, Standard Operation, Target 1, Active Sump, RH Lab Active Sump Released
|
On Wednesday November 21 at approximately 9am the level of the Remote Handling active sump was inspected and found to be at approximately the 7000L
level. The high level alarm sounds at approximately 5800L. The high level alarm had been silenced by somebody, and RH staff had not been notified.
It is unknown when the high level alarm was reached. The total sump volume is 7200L (which if exceeded will cause active water to spill on |

|
Repair of the west side manipulator in the west hot cell was completed today. Part of the repair was done by entering the hot cell using
double tank suits and supplied air. The repair was then completed on the master side of the manipulator. The manipulator is now operating smoothly.
Two sales representatives from Central Research Labs visited TRIUMF today as they were already in Vancouver on other business. I showed them |

Wednesday, October 24, 2012, 17:38, Isaac Earle, Repair, Target 2, Target, T1 & T2 Target Ladder Control System Status
|
During the recent shutdown for the T2/M9 joint repair Graham Waters replaced the corrupted application code on the controller RAM disk. The
T1 target position control is now functioning properly. T2 target position control is still not operational due to an electronics problem within
the motor driver. The T2 ladder position may still be moved using the portable control box. The T2 target ladder was moved to position 3 (10cm |

Wednesday, October 24, 2012, 17:34, Isaac Earle, Repair, Target 1, Target, T1-MK2 Target Repair Complete
|
The target ladder was detached, old delta seals removed, sealing surfaces cleaned using scotchbrite pad and a dremel tool, and delta seals were installed
on the lower face of the upper slide plate. The target was leak checked and found to have no significant leaks (no response from 2s helium spray
at previous leak location on upper slide plate). |

Friday, September 28, 2012, 15:19, Isaac Earle, Repair, Target 1, Target, T1-MK2 Delta Seal Leak
|
After removal of the leaky target cassette at position 3, plugs were installed on the target ladder and a leak check was performed. With
the target pumped down to approximately 10 mTorr, and helium detector gauge baseline of 9 on the 10X scale, a response of up to 25 on the 500X scale was
observed when leak checking the right side delta seal on the lower face of the upper slide plate using a standard 1s spray of helium at 3 psi. The |
