Maico and Travis moved blocks from ITE to ITW yesterday

Entry  Wednesday, July 11, 2018, 15:09, Anders Mjos, ITW, Maintenance, TM2, Nb#8, Uncovered ITW to toubleshoot 2A2M19 

The 2A2M19 beam profile monitor did not work and was e-faulted. After initial troubleshooting 2 blocks were removed form ITW to inspect the entrance module where the beam monitor is installed. The cable was found not to be connected and was quickly fixed. Blocks reinstalled. The work was done by Maico, Travis and Anders

Entry  Wednesday, July 25, 2018, 13:21, Anders Mjos, ITW, Repair, TM2, Nb#8, Leak check of ITW Entrance_Module_Leak_2018-07-25.docx

ITW Entrance Module was leak checked yesterday with the support of Vacuum Group (Dimo & Edi). The leak detector was connected to primary backing vacuum line. A leak response was found near the bellow for the beam profile monitor on top of the Entrance Module. It could be confirmed today by actuating the monitor, that the leak was indeed at that location. The plan is to move the TM and Entrance Module out for target exchange and repair, respectively. Drawings of the device available on ITA0200and ITA5128

 TM#2 with Nb#8 has been moved from ITW to the south hot cell.

Entry  Wednesday, August 01, 2018, 14:48, Travis Cave, Conditioning Station, Standard Operation, TM2, UC#23, Spent Target Move 

 TM#2 with UC#23 has been moved from the south hot cell to the conditioning station.

Entry  Wednesday, August 01, 2018, 15:12, Anders Mjos, South Hot-Cell, Standard Operation, TM2, UC#23, Target mounted - water leak on HS line 20180801_180130904_iOS.jpg

The heat shield water lines were not purged ahead of target exchange in the hot cell. This resulted in water leaking onto the new target assembly (heat shield) when the cooling lines were opened at top and bottom (for connecting leak detector). Excess water was wiped up with paper towels.

Entry  Tuesday, August 14, 2018, 10:27, Travis Cave, ITW, Standard Operation, TM2, UC#23, Module move 

 Both the West Entrance and TM#2 with UC#23 have been moved back into their places in the west target station. The Entrance module move wasn't completely smooth as it did suffer a little bumpiness when the shield plug part was installed, I was lifted back out again and no visible damage was observed on the delicate items.

Entry  Monday, September 24, 2018, 10:21, Anders Mjos, South Hot-Cell, Standard Operation, TM2, UC#23, Post Irradiation Examination (PIE) 20180924_161322929_iOS.jpg

UC#23 experienced short between target and heat shield as it was heated during operation. The inspection of the target after irradiation revealed that the left target leg was close to the heat shield opening and likely the cause of the short. Marks could be seen on the leg indicating contact. See attached photo. More photos are available on DocuShare

Entry  Tuesday, September 25, 2018, 08:01, chad fisher, South Hot-Cell, Standard Operation, TM2, nSiC#1, nSiC#1 install 20180919_132304.jpg20180919_143535.jpg

On September 18th installation of nSiC#1 was attempted on TM2. As usual, new fasteners were tested previous to insertion into hot cell and employed during installation. the last fastener to be installed was for the circuit D block. The fastener/air ratchet stalled immediately indicating a problem. The fastener was removed and a an attempt was made trying a new spare fastener. That fastener also jammed right away but could not be removed or installed any further.

 

A breaker bar was employed to achieve more torque and the fastener was able to be loosened, although it would not come completely out, dangling and wobbling like it was free. A claw type bar was used to add slight pressure to the fastener while it was loosened allowing the fastener to undo the rest of the way.

Target was removed and discovered that that insulator supporting circuit c and d blocks was quite broken and that a few chunks had fallen off. It was also notice that boefore the breaker bar had been employed that a piece of ceramic was on the table suggesting that the ceramic had been at least partially broken at the time of removal of the previous target. Also, the threads of the insert for circuit d showed damage an swarf.

Swarf was vacuum claned out of the circuit d thread insert and a machine tap ran through the insert twice.

nSiC#1 was reinstalled with new waterline gaskets and new c and d circuit fasteners with a little bit of the first 2-3 threads lightly coated with vacuum grease.

High current fasteners torqued to 130 in lbs.
