Installation of of operator-level lighting in the NHC was completed today according to drawing IRH1801.  2" x 2" Panduit was mounted to the wall on aluminum brackets to support the power cables.  These lights can be replaced remotely by unplugging the power cords using the manipulators, lifting the cable out of the Panduit with a hooked pole tool through the manipulator slave end removal roof hatch, lifting the light fixture off the support bracket with the pole tool, then installing a new fixture in the opposite order.  This RH procedure will be tested at a later date as part of NHC commissioning.

Testing was completed today on the NHC air and gas supply lines.  For each line a Staubli plug was installed on the fitting inside the hot cell, the line was charged with compressed air (50psi for gas lines #1, #2, and #3;  100psi for the air lines #4 and #5).  All connections inside and outside the cell were checked for leaks using Snoop including connections for the solenoid valves.  No leaks were found.  Correct operation of the solenoids was confirmed as well as correct plumbing (no lines crossed).

TM4 has been connected to ITE on Sep 04th. See attachment  for checklist.

TM4 TP2 could not be started  after module was connected back to ITE on Sep 04th. It was replaced with a new pump on Sep 05th. The new pump works fine.

 Targets SiC#34 , Ta#45,46,47,50 have been moved from the spent target vault to the mini vault.

 TM#4 with UC#24 has been moved from the conditioning station to the east target station.

I stopped TM4 and TCS vacuum system at TCS. TCS and TM4 is venting with argon now.

 Results of the electrical check with the spent Ta#56 attached, no target attached and the UC#24 attached. These test were performed on TM#4.

 Ta#56 has been moved from the south hot cell to the storage vault. It was placed in pail#169 and place in slot 2C of the vault. Also the vault is now full with 24 spent targets and can no longer accept any new targets. See the attached PDF for further details.

Chad and I leak checked TM4 HS line after UCx 24 is installed. No leak at 5xE-9atm.cc/sec.  Today, I did helium pressure test on HS line at TCS. No leak at 70 psi helium 0.0xE-9 atm.cc/sec.

TM4 has been connected to TCS. vacuum system and water system are started. Everything looks fine.

TM4 has been disconnected in ITE this morning. See attachment.

 TM#4 with Ta#56 has been moved from the east station to the south hot cell.

 Electrical Checks of the last two targets Ta#56 and UC#23

 Both the West Entrance and TM#2 with UC#23 have been moved back into their places in the west target station. The Entrance module move wasn't completely smooth as it did suffer a little bumpiness when the shield plug part was installed, I was lifted back out again and no visible damage was observed on the delicate items.

 The west entrance module has been moved from the west target station to the south hot cell, for a bellows replacement.

 The spent Nb#8 target was moved from the south hot cell to the spent target vault. It was placed in pail #168 and place in spot 2A in the vault. See the attached pdf for vault details.

I did a helium pressure test on TM2 HS line at TCS. At 70psi helium, the leak rate is 2.5 xE-7 atm.cc/sec. I think this is the number that close to result before which is 1.7xE-9 atm.cc/sec. WE know there is a small leak on this water block seal. Chad  and I did helium  spray check yesterday at SHC. It was good at bottom scale.  No much worry on this low E-7 range leak.

The heat shield water lines were not purged ahead of target exchange in the hot cell. This resulted in water leaking onto the new target assembly (heat shield) when the cooling lines were opened at top and bottom (for connecting leak detector). Excess water was wiped up with paper towels.

 TM#2 with UC#23 has been moved from the south hot cell to the conditioning station.
