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 by a floor swipe to check for contamination (none found).  All areas of the ante room floor were also swiped:  no contamination found.

The following measurements were taken in the NHC for comparison with the Soldiworks model:

SHC/NHC feedthrough panel fastener size:  1/4"-20,  1/2" long
NHC west wall to east edge of SEG block:  33-1/4" on south side, 33" on north side
NHC west wall to furthest extent of TCS (IRH1170): 40"
NHC west wall to wall indentation for viewing window: 46-7/8"
NHC west wall to end of existing ventilation duct: 4-1/8"
