Last Friday July-15, TM3 was leak checked at TCS. All air to vacuum seals on service cap are good. Helium pressure test on TM3 water lines(except
GE, HS, and Window) were done. Leak detector has no response at 0.0xE-9 atm.cc/sec. They are leak free. |

I started vacuum system.
I started TCS water system. The chiller does not work properly still. But, It will not affect the TM3 HV conditioning. HV cover is installed
on TM3 in TH. The module is ready for HV conditioning. |

The two 45 gal (m) drums of waste removed from the south hot cell in December 2015 and January 2016 were transferred from the north hot cell to the shaft
of the east vault tunnel on Monday, July 25th 2016 and subsequently to the east tunnel bunker in the vault tunnel on Tuesday, July 26th, 2016.The first
drum (removed from the hot cell in December) containing both activated and contaminated metals was measured at 900 uSv/hr @ .5 m and the second drum (removed |

The North Hot Cell was accessed today via the Ante Room for inspection, measurements,
and clean-up. There were no modules in the SHC or TCS, and no spent targets in the SHC. Under these conditions the maximum field in the NHC
was approximately 2μSv/hr. The inside of the cell was cleaned and swept, followed |

East manipulator on the south hot cell is showing signs of eminent wrist/tong cable failure. Some slight slippage was noted yesterday and confirmed by
a snapping sound and more slippage tomorrow. |

A hole was drilled in the NHC exhaust duct in the east end of the target hall above the hatch to the Ante Room. This will be used for measuring
NHC exhaust flow rate with a thermal anemometer. The hole was tapped and plugged with an NPT tap.
Flow was measured in the existing hole in the SHC exhaust duct in approximately the same location. Flow velocity was measured to be 1415 |

Testing was performed on August 9th on the ISAC nuclear ventilation system to determine if the existing ventilation system can achieve the required cell
depressions for both SHC and NHC under all expected configurations and if a proposed modification to the DDC control system can provide acceptable stability
and response time for the system. The proposed control system observes the lower of the SHC depression or the NHC depression + 10% (to avoid stability |

Requested by Aurelia, and approved by Friedhelm, TM3 service tray cover plate ITA2108 has been remove out of the module. The plated is checked for active
and contamination after removal. Then,It is double bagged, sealed , tagged, and placed downstairs in TH between south wall and green block . The
ram contact reading on the plate is about 10 usv/hr. We will do anther TM3 HV test at TCS without this cover plate. |

Disassembled the master side of the right manipulator this morning to check the wrist cable. The cable on the master side shows no sign of wear or fraying
suggesting that the slave side cable may be the item that is wearing. during disassembly of the master I did notice some loose parts that could have been
the source of the audible concern but should not have contributed to the slippage felt in the gripper. I will try and schedule Tuesday for entry into the |
