Type: Standard Operation 
Module: TM4 
Target/Number: UC#48 
Subject: UC#48 IGLIS Install onto TM4 

C. Fisher, A. Schmidt, A. Tam

UC#48 Handover satisfactory

  • Target taken out of glovebox and tested for fit
  • The left most triplet conductor leg was seen to be slightly misaligned, but the test fit showed that the bolt still threads on with some flexing from the suspect target leg.

Target inserted into NHC successfully

  •  tight fit with IGLIS means some rubbing of the two conductor legs did occur with the tool port tunnel
  • NHC target tray used, so tray from transportation was left in anteroom 
  • HVAC vacuum pressure dropped below threshold for a minute while toolport door was open.
    • Operations chained off SHC doors and RPG got involved to ensure the safety of everyone in the area

Target Install successful

  • A moment of rough handling of the target occurred when tilting the target towards operator in preparation for install
  • The suspected misaligned conductor leg did not initially accept a screw, but the use of a T-handled allen key and using a different screw from the package worked
  • Leak checks successful
  • Electrical checks successful

Replacements of NHC tool cart has been built, but some modifications may be made before it is inserted into the hotcell
