 Thursday, April 28, 2016, 06:28, David Wang, Conditioning Station, Maintenance, TM2, , TCS water system are turned off.
|
TCS water system worked fine overnight. I turned off TCS water system at 6:16 AM this morning. Start of purging TM2 water lines for helium pressure
test again this morning.
2016-4-28 7:58AM. Disconnected TM2 water lines at TCS. Purged them with compression air each for 5 minutes. |

Friday, April 29, 2016, 08:01, David Wang, Conditioning Station, Maintenance, TM2, , TM2 leak check at TCS, helium pressure test
|
Anders and I finished the most part of TM2 water lines helium pressure test yesterday.I list the system parameters and test result as below:
TCS IG1: 9.8XE-8 torr, TCS IG2: 9.6Xe-7 torr, TCS IG1S: 3.5XE-9 torr, TCS CG1A: 10 m torr
Helium pressure: 70 psi. Test time: 5 minutes for each individual circuit. 1 hour for all lines together test. |

Friday, April 29, 2016, 10:06, David Wang, Conditioning Station, Standard Operation, TM2, , I switched off TCS and TM2 vacuum pumps.
|
| I switched off TCS and TM2 vacuum pumps. The TM2 will be disconnected at TCS today and moved to silo on next Monday. |

|
A meeting was held on May 4, 2016 to determine the scope of the North Hot Cell project. The following was agreed upon by those in attendance:
The NHC will be a designated target change hot cell. It will be capable of performing all routine target operations (target removal/installation,
leak check, electrical check, video inspection, post irradiation examination, target waste packaging and removal) using the same method currently used |

Monday, May 09, 2016, 08:43, David Wang, Conditioning Station, Repair, TM3, , I reinstalled all the side panel on TM3 service cap.
|
They were moved for TM3 inspection job last week. All the bolts on the panel are hand tight only now since they will be removed out for camera installation
during next stage inspection. |

Tuesday, May 10, 2016, 13:54, David Wang, South Hot-Cell, Standard Operation, TM2, , SHC, TM2 leak check on window line and HS line.
|
Chad and I leak checked the TM2 HS and window lines after new target installation. The window line was very easy pumped down on LD. But, The HS
line only could pumped to 2-3 torr at first. Chad changed the VCR gaskets on HS line(target). It solved the problem. The LD could pumped both of
Window and HS lines to the bottom scale. Chad sprayed lots helium around the VCR joints. No leak has been found. WE will do helium pressurizing test |

Wednesday, May 11, 2016, 13:15, David Wang, Conditioning Station, Maintenance, TM2, , TCS tank top flange seal is changed this morning
|
| I changed TCS tank top flange seal(o-ring 42.00"ID X 0.275" DIA) this morning before TM2 was moved to TCS. |
|
Wednesday, May 11, 2016, 13:16, David Wang, Conditioning Station, Standard Operation, TM2, , TM2 and TCS vacuum system has been connected.
|
| TM2 and TCS vacuum system has been connected. I started all turbo pumps. Everything is good so far. |

Friday, May 13, 2016, 10:08, David Wang, Conditioning Station, Standard Operation, TM2, , Helium pressure test on TM2 HS and window line at CS with new Lp Ta target
|
These two lines are passed helium pressure test this morning. The LD base leak rate 0.0 X E-9 atm.cc/sec. The base pressure 0.0 X E-4 torr. Helium pressure
70 psi. applied helium to both line for 5minutes each. No response on LD during the test. |

Friday, May 13, 2016, 10:12, David Wang, Conditioning Station, Standard Operation, TM2, , TM2 water lines, heaters, EE, and EL are connected at TCS.
|
| The HV cover is installed on to TM2 after the connections. The HV key is returned back to B2 level. The TCS Faraday cage is locked. |

|
I did a 5KV mega test on TM3. Only5Mohm @5kV between coli line PQ and chassis(ground). It confirmed the close gap between P,Q and GE. Other lines
are ok. See attachment. |

|
The spent target vault door does not open or close. The emergency door closing did have to be used to close the door as it was locked in an open position,
the door stopped just off the open override limit. The door was closed and the spent target that was being assayed was placed into the mini storage. The
problem with the door appears to be related to the motor itself, as all the controls to the motor appear to be in working order. Also it was noticed on |
