|
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. |

Tuesday, June 09, 2020, 17:01, Isaac Earle, Development, Other, M9, Cables and helium leak check line installed to M9 service stand
|
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 |

Friday, January 13, 2012, 17:04, Isaac Earle, Repair, Target 2, Target, Broken Part found on M20 Beam Blocker
|
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 |

Friday, June 08, 2012, 16:52, Isaac Earle, Repair, Target 1, Target, Broken Manipulator Tape Update
|
The broken tape on the west side hot cell manipulator was found to be one of two "Z motion slave tapes". The manipulator can still
function normally with only one, however the remaining tape will see twice the load as usual. It was decided that repair of the manipulator may be
delayed until after the T1-MK2 target repair job is complete. Lifting of heavy objects using the west side manipulator will be avoided until after |

Wednesday, January 18, 2012, 12:01, Isaac Earle, Repair, Target 2, Target, Broken M20BB Bearing Removed, New Design Complete
|
The broken M20 beam blocker plastic shaft bearing was removed. Measurements of the bearing as well as the shielding disc (for which drawings
can't be found) were taken inside the hot cell and a brass replacement bearing has been designed based on these measurements.
Photos of the removed bearing, measured dimensions of bearing and shielding disc, and a PDF drawing of the new design are attached. |

Tuesday, August 06, 2024, 11:35, Albert Kong, Standard Operation, Other, BL1A Holding Tank, BL1A and RH Active Sump Draining
|
The RH active sump was drained (over Jul 31-Aug 01), in total approximately 5500 L of water was sent to city sewage.
We also tried to divert water from the BL1A holding tank to the active sump, and learned that we cannot run back-flow through the sump pump. The
valving configuration used here was V10, V1, SV1, V6 open - V2, V3 closed. (Note solenoid valve SV1 does not serve a purpose and energizing/powering-down |

Wednesday, April 04, 2012, 15:51, Isaac Earle, Repair, Target 2, Target, BL1A Update
|
Vacuum interlock defeat jumpers were removed for T1 and T2. The interlock was tested by venting the T1 and T2 volumes. Both packages registered
a vacuum trip, however only the T1 package shut off. A fault report has been filed to investigate this.

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. |

Monday, July 09, 2012, 17:17, Isaac Earle, Standard Operation, Target 1, Target, BL1A Start-Up Prep
|
- T1 & T2 targets switched to "remote" control
- Both target ladders were moved to Position 3 (12mm Be)
- T2 Q1 flow interlock defeat was removed (only required when target ladder is in position zero) |

Tuesday, June 23, 2015, 10:24, Isaac Earle, Standard Operation, Other, Other, BL1A Holding Tank Water Released
|
The water in the BL1A holding tank was released to the city sewer. This water was sampled, tested, and approved for release by RPG two weeks
ago. The total volume was 510L, a combination of water from the T2 and TNF systems. The total time required to pump out the water with all
valves fully open was 1hr2m. Paperwork for the water release was completed and returned to RPG. |
