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. |

|
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 |

Electrical check on TM#4 with SiC#29 has been done. The reading of the magnet coil and 60kV common is low at 750 ohms, normally this infinite. Awaiting
further instruction on if this is a pass or fail. See attached PDF for the rest of the details. |

The installation of the module side water block jig has been successful.
During initial attempts yesterday afternoon,
installation of the jig proved, as expected to be extremely difficult. This was primarily due a poorly position water block from a previous repair were |

|
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) |
Thursday, August 22, 2013, 19:38, Grant Minor, South Hot-Cell, Repair, TM3, , TM3 Rev 3 source tray - water blocks connected and torqued 6x
|
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. |
Monday, August 26, 2013, 18:22, Grant Minor, South Hot-Cell, Repair, TM3, , TM3 Rev 3 - all connetions made except steerers, IMG, and entrance window 8x
|
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 |

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. |

Today Chad entered the south hot cell on work permit 2013-08-29-3 to repair the leaking heat shield line. The heat shield line was removed from
the module and the surfaces cleaned. New C seals and spring were inserted and the line re-attached. During this time Chad also installed the new vacuum
gauge. Grant took video of this work and Keith some pictures. The video and pictures can be found on the M: drive (groups) in the RH folder. The total |
