Field readings have been taken at the south hot cell in preparation for entry into the cell to fix manipulator.

Field on contact at aluminum cover is 66 uSv/h, and a pole monitor into the cell through the tool port read 297 uSv/h.

South hot cell was entered to check to replace cable if needed. Wrist cable showed no signs of fraying or broken strands.

A tong with new cable pre-installed is now in the hot cell for next time this job needs to be done. There is also another spare tong cable not installed in a tong located in the box of manipulator repair equipment located inside the hot cell.

Both manipulator slave ends were lubricated whilst inside.

Plastic has been removed from the floor and any known active items in the hot cell moved to the south east corner in an attempt to shield the anteroom. Fields at the aluminum panel were reduced from 66 uSv/h to 58.8uSv\h. No contamination found on walls, floor, tacky mats, or standard aluminum cover. The aluminum cover with breathable air line hole did have 400 counts on 44-2, 1200 on ludlum.

Remaining items from anteroom have been bagged and removed (save the boot boxes, 1 garbage can and 1 coverall garbage can).

Room is ready to be surveyed so it can be deemed a non-boot box area for painting.

 The target was inspected by Anders and Chad. The target was in good condition as can be seen on the photos on DocuShare. Only minor accumulation of material on the EE.

SiC#33 was placed into pail #141 which in turn was placed into slot 2B of the vault. I was 295mS/hr upon removal from the south hot cell.

 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:

10" from floor:  102.44"
34" from floor:  102.40"
62" from floor:  102.48"
90"  from floor:  102.63"
118" from floor:  102.28"
142" from floor:  102.24"

Based on these results a partition wall plate width of 102.00" will be used for the bottom two plates, and 102.25" for the upper three plates in order to keep the gap on each side approximately 1/8"

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 to the partition wall Solidworks model (IRH1609).  The panel was bagged for disposal and a temporary 20"x20" panel was put over the feedthrough and secured with duct tape.  A permanent panel with anchored supports that is compatible with the NHC partition wall will be designed and installed at a later date.  A swipe of the NHC walls and floor picked up 30cpm after completion of the job.

A silo and blue steel frame are removed out of TH this morning. They are transferred  through ante room, and moved to experimental hall TM assembly area for a long term storage. Swipes are done on the silo and frame before and during move. No contamination has been found .

The spent UC#17 has been moved from the south hot cell to the spent target vault. See the attached pdf for details.

A steel plate  is covered on TCS. TCS roughing pump  is started now. The TCS will be pumping down during mini-shut down.

Argon venting is started

Ta#49 has been removed from the south hot cell and placed in the storage vault. It is in pail 146 and in spot 6A.

Broken cable has been replaced however a cable has hopped some pulleys inside. After two hours in cell the job was stopped with cables still off pulleys. Alternate tooling will have to be made and the job will continue Monday.

Maico entered the hot cell and re-strung the skipped cable back onto the pulleys this morning. Manipulator is now operational.

conductor insulators itd0053 and 54 have been replaced on TM2. All fasteners (1/4-20 x 1 1/4 vented) torqued to 60 in lbs.
