Wednesday, January 02, 2019, 10:26, Anders Mjos, Conditioning Station, Standard Operation, , , Restarrted TP1S
|
| Found pumps off after the holidays. Restarted roughing pump and TP1S |
|
Thursday, January 03, 2019, 13:30, David Wang, ITW, Repair, , , ITH:MP1
|
ITH:MP1 inlet pressure showed 10torr after power outage during holiday. All ITE/W turbo-pumps were tripped because of it. Removed one shielding block
above the vacuum station. Visually checked oil level and condition in pump. oil level is high. oil color is dark. no oil leak . Installed
a local convectron gauge on pump inlet. After pumping down, It shows pump is good. Tightened all KF 25 and 50 clamps on pump inlet side. Reconnected |
|
Thursday, January 03, 2019, 13:41, David Wang, Crane, Repair, , , Target hall crane PLC issue.
|
Target hall crane did not work properly after power outage during Christmas time. The only movement could be operated is crane rotation. Power is supplied
crane. The control board on N-S, E-W and up-down movement showed F51 error code which is tripped limit.. All these clues pointed to a PLC control
problem. Don dale was asked for help. He used the crane control PLC program on an old computer in RH control room reset the PLC system. Everything |
Friday, January 04, 2019, 08:48, David Wang, ITW, Standard Operation, TM2, , TM2 has been disconnected in ITW. 
|
TP1, TP2 are still connected for next week leak check. All water lines in TM2 are purged with 80 psi air, each for 5 minutes.
TP1 and TP2 had been disconnected. TM2 with UCx 25 disconnection checklist, See attachment. |
|
Friday, January 04, 2019, 14:38, Isaac Earle, North Hot-Cell, Development, , , NHC cameras tested
|
The NHC module support flange cameras (4 total) as well as the NHCSA camera were tested today and confirmed to be working properly. All cameras
were angled and focused properly, and displaying clearly on the monitors in the ISAC RH Control Room. Photos of the control room monitors are attached
below. |
|
Tuesday, January 08, 2019, 08:49, David Wang, ITW, Standard Operation, TM2, , TP1 TP1 have been disconnected in ITW
|
| Started argon venting of ITW now. |
|
Wednesday, January 09, 2019, 06:26, David Wang, Conditioning Station, Standard Operation, , , TCS vacuum pumps have been stopped.
|
| The tCS will be vented soon for TM2 move later this week. |
|
Wednesday, January 09, 2019, 13:29, David Wang, ITW, Repair, , , ITH:MP1
|
ITH: MP1 has been replaced due to its poor performance. Its motor and power cable are taken out and reused on new pump. Vacuum group assembled
them together, and installed the new pump. The new pump works fine. |
|
Thursday, January 10, 2019, 10:45, David Wang, Conditioning Station, Standard Operation, TM2, , TM2 is under vacum at TCS.
|
| TCS: TP1, TP2 and TP1S are started. |
|
Friday, January 11, 2019, 13:17, David Wang, Conditioning Station, Standard Operation, TM2, , TCS and TM2 vacuum system are switched off for this Sunday power outage.
|
| I will restart all pumps Monday morning. |
|
Friday, January 11, 2019, 13:59, Isaac Earle, Safe Module Parking, Development, , , SMP motor selection decision
|
SMP drivetrain design work is currently underway. Alejandro has selected a suitable 1200:1 reducer which will give a vessel rotation speed of 0.21rpm
with a 1725rpm motor (deemed sufficiently close to the SHC rotation speed of 0.17rpm). The reducer however is only rated for 0.33hp, and Allon's
analysis recommended we use a motor of at least 0.4hp |
|
Monday, January 14, 2019, 07:07, David Wang, Conditioning Station, Maintenance, TM2, , Restarted TCS vacuum system .
|
| No issue. |
|
Friday, January 18, 2019, 10:26, Isaac Earle, North Hot-Cell, Development, , , NHC sealing improvements and repeat of RH test for LED lights
|
The following NHC development work was completed under WP I2019-01-09-4:
Location of RH feature on operator level LED lighting updated to match IRH1800 Rev B design
Remote Handling test of the
LED fixtures was repeated using a 9' pole with hook attachment through the manipulator slave hatch from the Target Hall: both LED fixtures were removed |
|
Monday, January 21, 2019, 16:27, Isaac Earle, North Hot-Cell, Development, , , NHC in-cell camera wired to right side monitor
|
The NHC right side monitor has been wired to display the signal from the in-cell camera. This was tested using a snake camera on both of
the CPC-4 connectors.
|
|
Tuesday, January 22, 2019, 09:56, David Wang, ITW, Maintenance, TM2, , ITW water system maintenance.
|
ITW water system maintenance is done. All working paddle wheels and coils are replaced. ITW water system polyurethane tubes are replaced as well. Two
3/8" leak small valves on return lines are replaced. 85 liters of tritium water are transferred from storage tank to B2 level holding tank. LALC water
are refilled into S-tank. Restarted pump and checked system. Everything works fine now. No water leak has been found so far. |
|
Thursday, January 24, 2019, 10:34, David Wang, ITW, Maintenance, , , Changed 24VDC plugs of TP solenoid valves in ITW
|

Thursday, January 31, 2019, 14:16, Isaac Earle, North Hot-Cell, Development, , , NHC grounding approval
|
Franco Mammarella was consulted regarding electrical grounding of the NHC design (RS103 of Document-131915). After discussing the design,
and having grounding inspected by Randy Boehm, Franco approved the design and advised that the grounding system should be inspected periodically.
This task has been added to the Remote Handling inspection index on an annual schedule. A PDF copy of the e-mail correspondence with Franco is attached. |
