Frank and I did the test.  The emergency exit hatch on roof was opened and closed twice. Everything works fine.

 The entrance module has been moved to the east station to the south hot cell for inspection from the turbo pump explosion.

New IGLIS cables installation is done. Two bundle of new cables are pulled from ITE to electrical room. They are in one PVC conduit. The old cables are not removed yet. I will pull old cables out when new cables are installed onto device in ITE Faraday cage.

The broken pieces in ITE entrance vacuum pit are vacuumed out.  At SHC, There are 4 pieces on module collimator block top,  wiring scanner top. Chad removed them out at SHC. Electrical check at module top is done by diagnostics group. Everything works fine.

 The east entrance module has been moved from the south hot cell back to the east target station.

Filters were replaced by Curtis von Cube on March 5th. See work permit for details I2020-03-05-5

High  active water pump is started. The system resistance is recovering now. Everything works fine so far. Check ITW and ITE water leak after pump is started. Tiny very slow seep on two small ball valves pack seal. No big concern.                                 

PLC6 drop out in weekend caused the ITH MP1 and MP1s stopped. ITE turbo pumps were running still after that. Without back up pump, TPs started to trip off  later .  I found TP1,TP3, and TP4 were  tripped off this morning. And , The rest pumps ran with high current draw.  Jon Aoki restarted back up pumps and ITE turbo pumps. The ITE vacuum system works fine now.

Sorted and packed one 55 gallon drum with low contamination and active stuffs which are placed around silo area in the past. They include old poly water cooling lines replaced from ITE, ITW and TCS, contaminated paper  rags , gloves, and plastic bags,air cooling fans for turbo pumps, EE resistor packaged used on module top before, flow meters and cables used in ITW, etc. After packing, The field outside the drum on contact is less than 10 usv/hr.

A water leak was found on a fitting connecting ITW dump return line pressure gauge on top of exit module. TM tank flange, o-ring slot and o-ring were contaminated by water and water rust. Frank and I cleaned the flange and o-ring slot . We changed a new TM tank o-ring, vacuumed around other 3 module flanges. The leak fittings with pressure gauges were removed . I put a blind cap on removed fitting spot.. Water are switched back to ITW. No leak on blind cap.

Tom Kauss corrected the TH crane  festoon cable loops. He lubricated festoon cable wheels as well.    The maintenance is done.

Edi calibrated ITH:CM6, CM6S and ITM:CM3. By the same time,  ITH:MP1 and MP2  lubricate oil level are checked. Everything looks fine. No oil  leak on both pumps. 

Three manual valves are closed on TCS water system return line in experimental hall. See attachments. It is for TCS TK2 water level slow drop trouble shooting.  These valves will be opened again right after troubleshooting.  

TCS TK2 water level no change(11.1 inches) in this week after valves are closed. I will keep these three valves closed for one more week.

I opened these valves. In two week times, The TK2 level dropped 0.1 inches. The water level change could be a result of evaporation of water in system. We will keep watching on it.

Jason Sargeant mopped up TH floor this morning. The mop head was checked after the job. There are 1500 counts on it. He think this level is reasonable low. 3000 counts would be normal in past.

  ITW - 2A2

o    2A2DSP-TC3 - not connected in El room

o    2A2COL-TC2 - does not work inside module

o    2A2COL-TC3 - does not work inside module

·         ITE - 2A3

o    2A3COL-TC3 - works, but plug needs repair in ITE pit

 Anders and I checked ITW and ITE thermocouple status. See result above.  Frank and I will fix the 2A3COL-TC3 loose cable to plug issue.

Dan and I did the SMP annual  maintenance service today. Lid open/close , vessel rotation and limit switch check, lubricate chains, tighten fasteners, and visual inspection.  Everything works fine.

An inspection was performed on drive systems for both storage vaults (main and mini) by Adam Newsome and Dan McDonald. The functionality was not tested. Overall, nothing concerning was discovered.

Main Storage Vault:

• Chain inspected (OK) and lubricated
• Gearbox inspected - OK
• All drive system set screws checked and tightened (note: chain drive screw slightly loose)
• Sprocket alignment checked - OK
• Limit switches checked - OK
• Emergency close mechanism cable checked - OK

Mini-Storage:

• Chain inspected - OK
• Set screw checked - OK
• Gearbox inspected - OK (need inventory/spare in stock)
• Roller wheels checked - OK

ITW TP1 can not be started yesterday. Also, TP1S was difficult to start , and had a high current draw after.  We changed both of them in pit today. TP1 and TP1S are started successfully after replacement.

An electrical systems check was performed on the SMP by Adam Newsome and Travis Cave. Overall, there were no issues to note. The following is a summary of the inspection (Work Permit I2020-07-16-1):

- Checked condition of wiring for physical/radiation/UV damage
- Checked for cable tray debris or damage
- Checked inside control panel: components and wiring, labeling
- Verified camera views
- Checked connectors for damage
- Checked pendant for damage and verified labeling intact
- Checked limit switch wiring and condition
