Black "radio active" materials cabinet has been emptied, items bagged and removed from the anteroom. Cabinet itself has been swiped inside and out and also been removed from the anteroom. Most items have been removed from the anteroom now save some cardboard, rolls of plastic etc.

The wave guide from TM3 has been surveyed, swiped and removed from the anteroom and transported to rad waste for disposal. The wave guide has been stored in the anteroom since its removal.

  1307   Friday, August 05, 2016, 14:13 Isaac EarleNorth Hot-CellDevelopment  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 ft/min with the lid on the SHC.  Using duct ID 7.75", and assuming the average flow velocity is 90% of the flow at duct center, the flow rate was found to be 417cfm.  We will attempt to match this figure for the NHC when the ventilation tests are performed.  The tests have been scheduled for the maintenance day on Tuesday August 9th.

The anemometer probe and SHC test port plug were checked for contamination: none found.

  1306   Friday, August 05, 2016, 13:50 chad fisherSouth Hot-CellMaintenance  Anteroom clean out

Some items have been removed from the anteroom in preparation for painting. Items have been placed on plastic in the south hot cell service area. No contamination found so far.

TM#4 with UC#17 is now in the conditioning station.

UCx#16 has been removed from TM$ and UCx#17 installed, high current conductors toqued to 130 in lbs.

 

UCx#16 did not show the standard arcing marks on the 9 pin connector.

In regards to the 9 pin connector on number 17, it was by far the best fitting TM4 target with 9 pin as it required no "fiddling" during installation.

  1295   Tuesday, August 02, 2016, 11:02 Travis CaveITEStandard OperationTM4UC#16module moved

TM#4 with UC#16 has been moved from the east station to the south hot cell. The shield plug was also install remotely once it was hooked up due to alphas.
