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 |

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 |

South hot cell was entered to check to replace cable if needed. Wrist cable showed no signs of fraying or broken strands.
A tong with new cable pre-installed is now in the hot cell for next time this job needs to be done. There is also another spare tong cable not
installed in a tong located in the box of manipulator repair equipment located inside the hot cell. |

Plastic has been removed from the floor and any known active items in the hot cell moved to the south east corner in an attempt to shield the anteroom.
Fields at the aluminum panel were reduced from 66 uSv/h to 58.8uSv\h. No contamination found on walls, floor, tacky mats, or standard aluminum cover. The
aluminum cover with breathable air line hole did have 400 counts on 44-2, 1200 on ludlum. |
