 TM#2 with Nb#8 has been moved from ITW to the south hot cell.
Entry  Wednesday, August 01, 2018, 15:12, Anders Mjos, South Hot-Cell, Standard Operation, TM2, UC#23, Target mounted - water leak on HS line 20180801_180130904_iOS.jpg
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 ITW to the south hot cell. The shield plug was also installed remotely as well.

 TM#2 with the nSiC#1 target had its check done on it at the south hot cell see attached for results.
Entry  Monday, September 24, 2018, 10:21, Anders Mjos, South Hot-Cell, Standard Operation, TM2, UC#23, Post Irradiation Examination (PIE) 20180924_161322929_iOS.jpg
UC#23 experienced short between target and heat shield as it was heated during operation. The inspection of the target after irradiation revealed that
the left target leg was close to the heat shield opening and likely the cause of the short. Marks could be seen on the leg indicating contact. See attached
photo. More photos are available on DocuShare

On September 18th installation of nSiC#1 was attempted on TM2. As usual, new fasteners were tested previous to insertion into hot cell and employed during
installation. the last fastener to be installed was for the circuit D block. The fastener/air ratchet stalled immediately indicating a problem. The fastener
was removed and a an attempt was made trying a new spare fastener. That fastener also jammed right away but could not be removed or installed any further.

The south hot cell window has been found to be leaking oil. Upon inspection yesterday I found that the bolts compressing the gasket on the cold side
were "loose". I have re-torqued them to the specification provided by the manufacturer in the attached procedure.

Entry  Wednesday, October 03, 2018, 14:16, David Wang, South Hot-Cell, Standard Operation, TM4, Ta #57, Leak check TM4 Lp Ta# 57 at SHC. 
Tried to leak check TM4 Ta57# at TCS. LD failed to pump down properly at fine range. It always tripped at 4 torr. I cheeked all vacuum lines seals and
adapters on top of module to LD. Everything is good. Chad said the VCRs at SHC can not be tightened any more. Discussed with Anders, we decide to move
module TCS and helium pressure test there.  The same difficult happened last time on TM4 UCx24# at SHC when leak check. But,it is solved by pressurize

Cover 1 was removed from the exit module. Confirmed with David that the actuator rod that needed to be disconnected was the far left )as viewed by the
hot cell operator). The fastener for this rod was un-accessible from this side. Cover 1 was re-installed (two bolts left loose) and cover 2 was removed.
fastener holding the actuator together was removed and luckily it does have a remote start.

Entry  Thursday, November 08, 2018, 09:27, chad fisher, South Hot-Cell, Maintenance, , , South East Manipulator cable replacement 
The handle cable on the east manipulator of the south hot cell has been replaced. Old cable showed signs of wear but had no broken strands. Manipulator
is back together but still needs to be re-tensioned.
