|
2A2 window has been removed from ITW and beamlines has removed the beamtube from the penetration. The penetration has been sealed with plastic sheeting
and duct tape to maintain the ventilation depression between the 2A tunnel and the Target Pit.
Window is currently stored in a lead flask in the target hall. Window fields are 26 mSv/h OC, 1.2 mSv/h at .5m. There is a 10 uSv/h field outside |

Yesterday we installed the 2a2 window, the drive screw was torqued until 70
ft-lbs and we stopped, the yoke is not fully closed to its hard stop with roughly 7/8" to 3/4" still to go. Similar to identical conditions to
2a3 beamline window install, see https://elog.triumf.ca/TIS/RH-ISAC/647 for that install. Otherwise |

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:
- Scotchbrite pads (30 seconds) (after this step indium material from the previous seal was no longer visible on the sealing surface) |

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 |

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 |

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 |

|
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 |

|
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 |
