|
Tom Kauss inspected target hall crane below hook attachment pins and plates ITA6550-01 yesterday. He certified the use of these pins and plates. The
inspection of these pins and plates was in Target hall crane annual check list. It was issued as a calibration index by Isaac Earle in 2022-Feb-08.
After inspection, The inspection tag was issued and attached to pin. Tom has an inspection record on this job |

Thursday, September 21, 2017, 16:26, Anders Mjos, South Hot-Cell, Standard Operation, TM2, , Inspection of Source Tray
|
Chad and Anders inspected the Source Tray today using the camera in the hot cell. A dark spot was observed on one of the four insulators separating the
Extraction Electrode from the Ground Electrode. This could potentially influence the high leakage current. Some discolored areas were also observed in
the Service Tray, but these was present when the module was built. See attachment for details. |

|
Yesterday, Grant entered the Ante Room with David Wang to visually inspect the two sets of failed c-seals from the Heat Shield circuit, to remove the
second set from the Heat Shield water blocks, and to leak check the heat shield circuit with o-rings and a water-block-to-leak-detector fitting.
Some photos of the inspected seals are in the attached design review presentation. Some unusual marks were observed on both sets of failed |

|
To prevent TP bearings seize during shut down, ITW:TP3,TP4, TP1S TP4S have been started since March 06th. They work fine. The plan is to switch
them off this Thursday, and restart them in May before ITW in use. |

Monday, July 28, 2014, 17:26, Ron Kuramoto, ITW, Repair, , , ITW:IV5 Air leak repair
|
Air leak was found at the Solenoid control valve located in the Pre-Separator & DB0 room. The gasket between
the solenoid body and its manifold block was broken, see attached photos. The gasket and solenoid body were replaced. Air was turned back on
to IV5 (B/L gate valve) with no apparent air leaks. The gate valve was actuated open & closed from the control room seeing both limits successfully. |

|
Measured resistance on safety limit switches for FC5 on Exit Module 2. Determined that the in connected signal did not work (shows not connected irregardless
of FC position). Confirmed proper operation of the OUT limit. See attachment for details. The Harp 5 x and y signal connectors were checked and reconnected. |
