TM2 coil line R,U has been vacuum leaked check at the hot cell and has passed with no response from the leak detector.

  998   Wednesday, July 15, 2015, 11:18 David WangSouth Hot-CellRepairTM2 leak check coil line(R,U) on TM2 at SHC

Chad and I leak checked the coil 1 circuit(R,U) after rebuilt coil line is installed on TM2 source tray. The pumping down on the circuit is very quick and smooth. The LD base lake rate 0.0xE-9 atm.cc/sec. Base pressure0.0xE-4 torr.

Chad sprayed lots helium on the R( coil 1+)and U(coil 1 -) water blocks. During  1 minute waiting time, there is no any response on LD. The R and U water blocks and C-seals are leak tight.

Gas lines extensions installed yesterday were too long and gas lines touched top inside of containment box. They have been removed and the gas lines re-installed in their original manner. Gas lines have been "adjusted" as to clear the tube heater lines, which was the original issue.

Target pit Hepa filter has been replaced today. There is 500 counts on swipe which is taken inside of the replaced filter. The field measurement on the filter wood box  is less than 0.5 usv/hr on contact. Right now,The outlets of the old filter are sealed with thick plastic and duct tape. The whole filter is wrapped with plastic sheet and tape. It has been moved to SHC ante room.  It will be moved out of there by Tony.N soon with RPG help.

The leaking 1/8 NPT(M)-1/4NPT(F) adapter on the ITW dump circuit is replaced.

  1009   Wednesday, July 22, 2015, 12:13 chad fisherSouth Hot-CellRepairTM2 TM2 Short Findings

Pin X was unplugged, short remained, however any slight pressure on the block towards the source tray makes the short go away.

Confirmed clearance between the EE and thr R / U coil lines as well as MSP of coil line.

Camera inspection would seem to indicate that ALL issues stem from a common location...there is a spot where both the pin X waterline and the one of the R / U waterline  contact the heat shield waterline...one on one side of the heat shield line and the other on the other side.
