 A 55 Gal. drum was remotely lowered into the south hot cell. It was then filled with compressable waste. Then the drum was remotely removed from the south hot cell. The drum measured about 20microSv/hr upon removal from the south hot cell.

 Results from the electrical check of TM#4 at the south hot cell with no source tray. R&U are shorted and when meggered A&P have a value of 193k ohms. See attached for details.

 TM#4 has been moved from the conditioning station to the south hot cell. The module has no source tray.

  1945   Friday, June 21, 2019, 07:16 David WangSouth Hot-CellDevelopmentTM4 TM4 new source tray leak check at SHC.

New source tray was installed on TM4 yesterday. LD was used to pump down all water lines. Tube heater +D circuit has a big leak  around water block area. At base LR5.5 XE-5 atm.cc/sec, base pressure 170 mtorr, When Chad  moved this helium probe close to  water block area, The leak rate on LD went to maximum level right away. When the probe was moved out of water block area, the LR went back to base level. The test repeated again with same result. Also, Before helium spray test, I applied 80 psi air into the circuit. The air pressure can not be held in the circuit. The pressure drop on the line is quick. This shows a big leak on  D line as well. The rest water lines are fine. I pumped all of them down to LD bottom scale without problem. Chad and I helium sprayed window and MSP water blocks. No leak has been found.  The only line we have problem is the D line.

D line is still leak after repair and installation. We suspected the c-seals issue on this module. So, all water lines have been sprayed with helium for leak check.  Found "B" line target oven negative  is also leak. The rest line are good on helium spray leak check.  The further investigate on thi issue is taken place now.

  1952   Monday, July 22, 2019, 14:51 Adam NewsomeSouth Hot-CellStandard OperationTM4No TargetTM4 Move

TM4 has been moved from the South West silo to the South Hot Cell. New source tray, no target.

  1953   Friday, July 26, 2019, 11:28 David WangSouth Hot-CellStandard OperationTM4 TM4 move from SHC to TCS.

Tm4 has been moved from SHc to TCS without containment box. It is a new source tray on TM4.  A layer of plastic sheet was put on TH floor on module pass route during the move.

  1954   Friday, July 26, 2019, 11:41 David WangSouth Hot-CellStandard OperationTM4 TM4 with spare target electrical check and leak check.

Electrical check on TM4 with spare test target. PQ is still shorted to RU. But, The short between 60KV bias and PQRU which we found last time is gone.  Target to PQRU at 250V mega measurement: 22.08 M. All conductivity between ABCD are about 5.0 m ohm which are good. All other ohm meter and Mega measurements are OL. Helium spray leak check on HS target VCR fittings is passed. Two blank offs are installed on source tray window cool lines. They passed  leak checked at SHC as well.
