 Thursday, August 25, 2016, 08:36, David Wang, Conditioning Station, Standard Operation, TM2, , Helium pressure test on TM2 HS water lline
|
I did a helium pressure test on TM2 HS water line at TCS. Leak detector base leak rate only could get to 1.8x e-8 atm.cc/sec at this moment. Applied 5 minutes 70psi helium on it. No leak has been found at this level. I connected water to this circuit after the test for weekend TM2 conditioning at TCS.
I will do another helium pressure test after the conditioning. The LD base leak rate should be 0.0Xe-9 atm.cc/sec at that time.
2016-08-29: LD Base leak rate 0.0xe-9atm.cc/sec.TM2 HS line helium pressure check again after conditioning. 70psi helium 5minutes. no response on LD. HS line is perfectly sealed. |

Wednesday, August 24, 2016, 20:27: IG2 and IG1S on. Checked on water system.
Conditioning by ISAC operations. Water flow tripped power supplies after a few hours of conditioning at 580 / 230 A and 30 kV. See operations e-log for details. |

TM#2 with Ta#49 has had its electrical check and was moved to the conditioning station. see the attached pdf for the electrical check details.
The electrical check has been edited to reflect that well the original has been just not the PDF. |

|
Plastic has been removed from the floor and any known active items in the hot cell moved to the south east corner in an attempt to shield the anteroom. Fields at the aluminum panel were reduced from 66 uSv/h to 58.8uSv\h. No contamination found on walls, floor, tacky mats, or standard aluminum cover. The aluminum cover with breathable air line hole did have 400 counts on 44-2, 1200 on ludlum.

|
South hot cell was entered to check to replace cable if needed. Wrist cable showed no signs of fraying or broken strands.
A tong with new cable pre-installed is now in the hot cell for next time this job needs to be done. There is also another spare tong cable not installed in a tong located in the box of manipulator repair equipment located inside the hot cell.
Both manipulator slave ends were lubricated whilst inside. |
