I pumped down conditioning station IMC today. The inside bellow pressure is -20 psi on the gauge.Visually checked the bellow before and after pump.The
bellow is in retracted condition now. |

An autopsy was performed on UCx#3 yesterday afternoon. This autopsy followed the plan written by Anders. Indeed, both sides of the target oven had seperated
from the central block.Pictures were taken by Anders and Pierre.
After the disection the target was placed back in a can under argon. Any small piece were placed in a zip lock bag and also put in the can under |

UCx#3 was packaged into a spent can, double bagged and the bag and cans filled with argon as much as possible. Lid was attached and can moved to the
storage vault. The target was placed in in Pail 93, and placed into slot 1C of the vault, it was 11.7mSv/hr when removed from the south hot cell. See attached
file for latest vault details |

UC#3 was removed from TM1 this morning. Upon removing the oven heater bolts BOTH legs fell demonstrating that both sides of the oven tube have
broken off from the central block.
Target was put into a can under argon for disposal after the module is removed from the cell. |

I had changed all old induction coils for flow sensors in ITE .I checked all ITE water signals on control boards in electrical room.They are all very
stable and constant.All ITE inductions coils work fine now. |

TP2 on TM4 has been replaced with a new turbo pump , I didnt reset the controller in electrical room.So this new pump start to run at 8083 hours
on ITE TP2 controller. The new TP2 pump properly started. It works fine now. |

|
All targets in the mini storage have been moved to F-308s and those flasks have been moved over to rad waste. The transfer of target occurred on January
10th and the flasks were moved to rad waste on January 11th. Contamination was found on the bottoms of some of the pails and was removed, some of
the contamination was difficult but not impossible to remove from the pail bottoms. |

Hi Remote Handling,
The guage on the IMC circuit in the Target Hall is reading atmosphere, and the bellows is currently relaxed (i.e. expanded), whereas it should
be reading about -20inHg and the bellows should be contracted (i.e. compressed). |

Looks like the UC target s #1 and #2 were found invalidprize winners for their all inclusive trip to Chalk River and have thus been placed back in to
storage for the next draw. In their place a pair of lucky Ta targets won, seems to be Ta lucky draw this year, Ta#28 and #29 have been placed in the mini
storage for several fabulous day and wondrous nights, before being whisked away on their all inclusive one way trip to Chalk River. See attachments for |

Well the first of this year's lucky winners to win a fabulous one way trip to Chalk River are as follows. UC#1, UC#2, Ta#25, Ta#26, and Ta#37. First
these lucky winners will get to stay several days and night in the lovely all inclusive mini vault before being loaded in to their very own private F-308
flasks to be whisked away off to fabulous Chalk River. |

Spent target assay completed. A total of 16 target were looked at, 13 were low enough to be assayed and those 13 are at shippable levels, the other 3
of the 16 looked at were too hot to ship and assay. See attached pdf for complete details. |

High Voltage (HV) testing was completed on TM1 today. Vacuum was very good 1.9 x 10^-7 T in the service cap, 3.2 x 10^-7 in the containment box,
and 2.0 x 10^-6 in the secondary. The voltage was successfully brought up to 27kV with a current draw of 0.12mA and o sparking. At the next step, 30 kV,
the current draw was above 0.3mA and sparking was beyond 20 sparks per minute. The module should not be taken above 27kV. There is the possibility this |

TM1 was high voltage tested without a target on November 16, 2011 with Don Jackson, Pierre Bricault, and Bevan Moss. The module was able to hold
up to 25 kV but between that and 32 kV there was lots of discharge which could be measured in the vacuum. See the attached plot for the voltage current
and sparks. |
