Ta#39 has been transferred to spent target storage vault. Ta#39 was placed into pail #106 and placed into spot of 4C of the spent target vault. The pail
measured 95.8mSv/hr upon removal from the hot cell. See attached PDF for details. |

Friday, July 05, 2013, 09:22, chad fisher, South Hot-Cell, Repair, TM3, , Service Tray Water Block Inspection
|
I have inspected the service tray water block and suggest that they SHOULD be cleaned/polished before we install the new source tray.
The water blocks have slight water scalling to the inside of the ID of where the c seals locate.
I have taken two close up pictures of each water block for reference and to document their current state. They can be found at http://documents.triumf.ca/docushare/dsweb/View/Collection-10841 |

TM4 has been connected in ITE. All turbo pumps have been started now. The pumping down on TM4 and ITE is good so far. The water interlock check on TM4
is done,and everything is fine. The ITE IG1 still couldnt be turned on even if we replaced a new TM4 IG1 at CS. The problem is on the connecting
cable from ITE to electrical room or gauge controller. I talked with Friedhelm and vacuum group will be noticed on this problem. |

|
The water block sealing surfaces on the module-side of TM3 were polished this week by Chad Fisher, using his air-ratchet controlled rotating head tools
(single and double-surface polishing tools).
Photos of the polishing tools in-use are attached (from August 16 - 21, 2013) |

After a great struggle with the water block jigs, the TM3 source tray was finally advanced fully into the service tray and all water blocks were connected
and torqued to spec in the hot cell by Chad Fisher.
Notes and description of problems encountered during the installation: |

Friday, August 23, 2013, 18:32, Grant Minor, South Hot-Cell, Repair, TM3, , TM3 Rev 3 - steerer wire broken from connector on module side
|
While continuing on the TM3 Rev 3 source tray installation, Chad noticed today that one of the steerer wires is broken and has come out of the thermocouple-style
connecter block (see attached photos).
From drawing ITA2826 (Rev D02 attached) it is likely that this is for either the "upper" or "right side" steerer plate. |

Today Chad finished making all connections to the new source tray, except for:
- steerers - broken wire, must be repaired at a later date
- IMG gauge - bracket required, old bracket thrown out with previous tray by accident, see ITA3301, must be installed at a later date |

Monday, August 26, 2013, 18:26, Grant Minor, Conditioning Station, Standard Operation, TM3, , TM3 moved from Hot Cell to Conditioning Station
|
Target Module 3 with no target, and a partially-installed Rev-3 source tray (no steerers connected, no IMG connected, entrance window lines blanked off
on module side and not connected to containment box) was transported successfully to the Conditioning Station by Travis Cave and David Wang at around 4pm
today. David attached the vacuum system for start of pump-down to prepare for leak checking. |

A huge leak had been found on HS circuit during 60 psi helium pressurize test. Other circuits are free of obvious major leak at present .We will test
them again once the TM3 is back to CS. See attachment for details |

Thursday, August 29, 2013, 09:08, chad fisher, South Hot-Cell, Repair, TM3, , Heat Shield Circuit Leak
|
The heat shield circuit was pressurized with air (15-20 psi) and snoop applied to the water block joint and brazes. Bubbles formed at the joint between
the two water blocks indicating that the leak is a c seal problem. Pictures attached but also on docushare Collection-11285. |
