|
The sealing surfaces of the module side heat shield water block were polished on September 9th in the morning using Chad's polishing tool with
the following attachments:

Tuesday, April 21, 2015, 17:14, Isaac Earle, South Hot-Cell, Standard Operation, TM1, UC#12, UC#12 Installed in TM1
|
On Friday April 17th, UC#12 target was installed in TM1. One of the copper water lines was bent slightly as the target was lifted into the module
which caused ~15 minute delay due to difficulty getting the VCR nut threads to engage. Other than this the install went smoothly.
During replacement of the containment box panel two of the threaded holes were found to be stripped. One on the top at the center, the other |

Wednesday, May 04, 2016, 11:14, Isaac Earle, North Hot-Cell, Development, , , North Hot Cell Scope Decision
|
A meeting was held on May 4, 2016 to determine the scope of the North Hot Cell project. The following was agreed upon by those in attendance:
The NHC will be a designated target change hot cell. It will be capable of performing all routine target operations (target removal/installation,
leak check, electrical check, video inspection, post irradiation examination, target waste packaging and removal) using the same method currently used |

Friday, July 29, 2016, 14:27, Isaac Earle, North Hot-Cell, Development, , , North Hot Cell Measurements & Cleanup
|
The North Hot Cell was accessed today via the Ante Room for inspection, measurements,
and clean-up. There were no modules in the SHC or TCS, and no spent targets in the SHC. Under these conditions the maximum field in the NHC
was approximately 2μSv/hr. The inside of the cell was cleaned and swept, followed |
|
Friday, August 05, 2016, 14:13, Isaac Earle, North Hot-Cell, Development, , , Preparations for NHC Ventilation Test
|
A hole was drilled in the NHC exhaust duct in the east end of the target hall above the hatch to the Ante Room. This will be used for measuring
NHC exhaust flow rate with a thermal anemometer. The hole was tapped and plugged with an NPT tap.
Flow was measured in the existing hole in the SHC exhaust duct in approximately the same location. Flow velocity was measured to be 1415 |

Wednesday, August 10, 2016, 14:38, Isaac Earle, North Hot-Cell, Development, , , North Hot Cell Ventilation Test Results
|
Testing was performed on August 9th on the ISAC nuclear ventilation system to determine if the existing ventilation system can achieve the required cell
depressions for both SHC and NHC under all expected configurations and if a proposed modification to the DDC control system can provide acceptable stability
and response time for the system. The proposed control system observes the lower of the SHC depression or the NHC depression + 10% (to avoid stability |

Wednesday, September 07, 2016, 11:39, Isaac Earle, North Hot-Cell, Development, , , NHC North / South Wall Gap Measurements
|
Measurements were taken today of the NHC north/south wall gap at the location where the NHC/TCS partition wall will be installed (43.375"
from the NHC west wall). A HILTI PD40 laser range meter was used for the measurements. They were taken at 10", 34", 62", 90",
118", and 142" from the floor which matches the top of each cross-beam. The results are below: |

Thursday, September 15, 2016, 11:05, Isaac Earle, North Hot-Cell, Development, , , NHC / SHC feedthrough panel removed
|
The sheet metal panel covering the NHC/SHC feedthrough port was removed today using a slide-hammer to pull out the concrete anchors (this oversized panel
would have interfered with the NHC partition wall). 50cpm was found on the inside of the panel, 100cpm on the NHC side lip of the feedthrough, and
350cpm on the face of the shielding bricks in the feedthrough. Various dimensional measurements of the feedthrough were taken which will be added |

Tuesday, November 08, 2016, 14:04, Isaac Earle, North Hot-Cell, Development, , , Interference check with TCS turbo pump and proposed NHC duct routing
|
David Wang and I accessed the NHC today to check if the proposed duct routing (IRH1618) will interfere with servicing or replacement of the TCS turbo
pump. A piece of plywood was placed in the future position of the NHC/TCS partition wall (IRH1609), and a ducting elbow was placed at the approximate
position of the nearest elbow to the turbo pump. |

Friday, December 09, 2016, 14:58, Isaac Earle, North Hot-Cell, Development, , , NHC service area floor and top of roof block painted
|
The concrete floor in the North Hot Cell service area and the top of the NHC roof block in the target hall have been painted with Macropoxy 646
oil based epoxy paint, colour Flint Grey. Two coats were used for the NHC roof, and one for the service area floor.

Tuesday, January 17, 2017, 13:45, Isaac Earle, North Hot-Cell, Development, , , NHC ducting installed
|
The new ducting section connecting the existing duct termination in the TCS space to the NHC partition wall has been installed by Smith Sheet Metal
contractors. The installation drawing is IRH1618. There was not enough clearance between the duct pipe and the TCS vessel to butt weld the
new ductwork as originally intended. Instead a flange was welded to the existing pipe and also to the new section and the two were bolted together. |
|
Wednesday, January 18, 2017, 11:53, Isaac Earle, North Hot-Cell, Development, , , NHC partition wall installation complete
|
The final panels of the partition wall were installed today as per drawing IRH1609. Sealing, finishing, and painting of the NHC walls and
floor can now commence.

Thursday, February 09, 2017, 14:07, Isaac Earle, North Hot-Cell, Development, , , North Hot Cell Shielding Window Gaskets Changed 23x
|
The North Hot Cell shielding window gaskets have been changed and the window has been filled with new oil. Although there was no noticeable
oil leaks before starting the job, the gaskets had not been changed since initial installation approximately 15 years ago, so they were done now as part
of construction of the new cell. The work took place between January 26 – Feb 8, 2017 following the attached PDF “Full procedure |

Friday, February 24, 2017, 15:12, Isaac Earle, North Hot-Cell, Development, , , NHC interior walls/floor/ceiling re-finished, sealed, and painted 8x
|
The North Hot Cell interior walls, floor, and ceiling were re-finished, sealed, and painted by Omni Coating from Feb 6 - 17 under PO #3036471. This
job required 2-3 people for 4-6 hours per day over the 2 week period. First the existing surfaces were ground and/or sanded to remove existing coatings
and protrusions/sharp edges. This was followed by a coat of primer to highlight uneven surfaces and improve adhesion of following fillers and coatings. |
