|
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. |

Friday, June 21, 2019, 07:16, David Wang, South Hot-Cell, Development, TM4, , 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. |

Friday, July 26, 2019, 11:41, David Wang, South Hot-Cell, Standard Operation, TM4, , 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. |
