Left (short) is switched with bottom. So on module:

Frank and I removed the panel, disconnected the "Left"cable  inside panel,  and checked  cable to ground resistance. "Left "is dead short to ground on ohmmeter check still. So the short could be on cable or inside source tray.  Further investigation is planned to confirm the short  location.

The were issues with both left and right master ratcheting;

- the left handle was getting stuck in a close position when there was a higher ratcheting tension added

- the right ratcheting was not tightening preventing proper use of the manipulator

Chad and myself were able to identify a missing set screw for the tong cable.

Once this was added the issue with the left master ratcheting seems to be solved.

Lubricant was added to the left master ratchet and this seems to solve this problem as well.

There was also an observation of missing set screws on the spare manipulator for attaching the wrist to the ratcheting handle, which will need to be ordered and attached.

TM2 old source tray and TM4 optic tray are stored together in vault tray#9. The fielding measurement at SHC post 0.5 meter distance:
 

March 1st 2019, maximum 14.6msv/hr, minimum 4.78 msv/hr

Nov 2nd 2020, max 7.11m sv/hr, min 2.5msv/hr.

TM2 has been moved from ITW to the South Hot Cell.

Reading at ITW: 114 mSv/hr

Reading at SHC: 85 mSv/hr

TM2 has been moved from the Conditioning Station to ITW. 

TM3 has been moved from the Silo to the South Hot Cell.

TM3 has been moved from the South Hot Cell to the Conditioning Station. No containment box.

TM3 was remotely moved from the conditioning station to the South Hot Cell. No containment box.

The Target Hall Crane has been shut down in preparation for the power outage tomorrow (Dec 22). Power will be restored on Dec 23.

Dec 23 update: power has been restored. The crane appears to be in working condition as there is no fault indicator on the PLC.

USB was discovered to be in the reverse direction and will need to be change around to become operational

01/Dec/2020

USB was pulled from conduit

While attempting to re-pull the USB in the correction direction, the ethernet cable was damaged and need to be replaced,

(thanks to the Hubert's team for the wire help) 

It was decided that it was too problematic to re-pull the wires with all other wires in the way. Therefore all the wires were removed from the operator control panel, and pulled so that the USB, USB power cord, and ethernet could be re-pulled all together.

However, even once all the wires were re-pulled and reconnected it was discovered that the USB had become damaged, and was removed again.

23/Dec/2020

- A new conduit was added through to the NHC, for only the USB

- USB was fed through, reconnected, and tested

- Putty will need to be added around the conduit to ensure a good seal into NHC

TM3 was remotely moved from the South Hot Cell to the conditioning station. No containment box.

ITE annual HV test is done. No module in station. The bias power supply has been ramped up to 49KV on control page. We still have voltage limit issue on this PS at 48KV so it only can go to 47.7 KV on PS panel. No major spark during test.. The test result is same as last year test which was did in March 2020. 

Cables were disconnected for steers in containment box. The Megga measurement (500V) result from the top of the module:

Left to right: OL, left to top OL,  left to bottom OL, right to top OL, right to bottom OL,  Top to bottom OL. And all of them to ground are OL.  No short on cables from module top to steers itself. The short should be inside the steers. It will be confirmed with directly test on steers.  

Ramp up ITW bias to 57KV. no spark. 200uA leaking current at 57KV. The test is done without target module in station.   ITW water circuits are looped in pit.  EE , EL are switched off during the test. 

High active water are purged to holding tank at B2  level. There should be around 48 gallons are purged out of system. No purging on dump circuits on both ITW/ ITE.

TM4 is moved from TCS to SW silo. The moving is smooth.

Old resin can:  0.5 meter 360 degree rotation above silo area, 350u sv/hr.   On contact  3.0 to 3.5 msv/hr.  It was replaced during 2017 winter shut down, and stored in silo since then.

2a window RH clamp: 0.5 meter, 160 usv/hr.  On contact, hottest spot 3.5msv/hr, general,1.8 msv/hr. 

 Both of them were raise out of storage silo with TH crane. Pole monitor was used for field check.

 TM2 at SMP under vacuum. TM4 at silo.  Frank and I did the tests. Everything is fine on TM4 check.  On TM2,  all mega test at 500V are around 200K ohms which is so abnormal. We will move TM2 to TCS and  start investigation there.

Vacuum cleaned ITW and ITE station.
