|
New cleaning and polishing pads have been inserted onto the hot cell as well as rubber bungs and a new blank off.
The inital waterblock cleaning with the "scotch bright" pads has been completed. See attached pictures...the first picture being before
and the second after. |

Thursday, February 13, 2014, 09:24, David Wang, South Hot-Cell, Repair, TM2, , Leak check TM2 tube heater (+) water line with rubber insert blocked WB in SHC
|
Chad and I did the Leak checked TM2 tube heater (+) water line with rubber insert plugged water block on " D" in SHC. The
Leak detector was very easy to pump down to the bottom leak rate and pressure. Chad checked the helium flow in SHC, and sprayed 10 second helium on
the block. There is no response had been found during the test. The test was repeated again and no leak has been found. See attachment pictures. |

Thursday, February 13, 2014, 13:30, David Wang, South Hot-Cell, Repair, TM2, , pressure test on TM2 tube heater +(D) water line.
|
Chad and I did the pressure test on TM2tube heater+(D) water line at SHC with shop air.We tested from 30psi to 80psi on both side of D line. The
bubbles were found at 50-55psi on blank off seal in SHC. |

|
I did the helium pressure test on Tube heater+ line this morning. The vacuum on CS and TM2 are very good. The base lake rate on leak detector was 1.7xE-7
atm.cc/sec. Base pressure was 0.0xE-4torr. I applied helium to the "D"line .The test started from 30psi up to 80psi on both side "D"
line.The base leak rate slightly changed to 1.9xE-7 atm.cc/sec during the test,but not base pressure. At this base leak rate level, No obvious leak had |

|
Chad and I did the leak check on TM2 tube heater (+) water line with blank off and C-seal installed on WB at South Hot Cell.The
line was easy to pump down to 0.0xE-9atm.cc/sec and 0.0XE-4 torr on leak detector. Chad flushed lot helium around the water block (10 sec spray). No response
had been found on leak detector. |

Tuesday, February 25, 2014, 10:00, David Wang, Conditioning Station, Repair, TM2, , helium pressure test on TM2 tube heater (+) water line with blank off(C-seal) installed on WB. 10x
|
I did the helium pressure test on TM2 tube heater (+) water line with blank off(C-seal) installed on water block at CS.The leak
detector was hooked directly to the top of the module this time. So base leak rate and base pressure were at the bottom scale on LD. 30 -80 psi helium
was applied to the D lines(both side) with10 psi increasing each time. There is no any tiny response hasbeen found during the test. The lines |
