I started TCS water system this morning to check if the chillers work properly.

I finished the rest TM2 connections to CS, and started CS cooling package. Everything works fine so far.

3 turbo pumps on TM4 and CS have been started. The pumping down is good so far, The TM4 PNG1 reading is more than 10 times higher than IG1 which is at the same chamber. It could be a controller problem.  Other 3 high vacuum gauges behavior normal.  The TM4 IG1 is replaced today and it works fine now.

TM3 has been connected in CS.Three turbo- pumps have been started. The pumping down is fine so far.

I started TCS roughing pump. TM3 TP1 and TP2 will be started tomorrow morning.

TM2 in SMP with old SiC #39 target on it. SMP vacuum pump is started.

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.                                 

TM3 turbo-pumps are started at TCS. We will keep pumps running until next Wednesday.

High active water system  was  checked before restart. A small water leak on resin can supply valve was found. It is fixed. MP1 and MP2 were started and checked separately. System pressure and flow rate are normal.MP1 is in operation now. 

It was noted on Nov. 9 that a squeaking noise was present when the turntable was rotated CCW with a module present.

Upon inspection, it appears the issue could be due to drive chain misalignment and improper tension. Furthermore, it was noted that a shaft collar on one of the existing chain tensioners was broken (a replacement was ordered).

Repairs will be performed on Nov. 19 to resolve these issues by re-aligning the chain, and resetting the tensioners. The turntable will be tested. This e-log will be updated once the work is complete and the system is returned to a functioning state. See Work Permit I2021-11-09--3

Edit, Nov. 19: the aforementioned repairs were completed and the turntable has been tested and is operating correctly. No squeaking noise is present. It is suggested to increase the diameter of the two chain tensioner shafts (and thus modify related bearing and shaft collar components) in order to prevent bending of the shaft which was observed. This will be done in the near future.

 New spring idlers were installed onto rotational chain drive for SHC roof. Operation ran smoothly in both directions to full limit. Chain was noted to have adequate slack when not on driven side. Periodic checks to confirm operation will continue in the following months to guarantee proper operation.

Targets NiO#1(101), Nb#5(85), TaC#1(92), and ZrC#5(81) have been moved from the storage vault and placed in the mini storage. The F-308 flasks have also been moved in to the target hall as well. The attached are the current statuses of both vaults.

All targets in the mini storage have been moved to F-308s and those flasks have been moved over to rad waste. The transfer of target occurred on January 10th and the flasks were moved to rad waste on January 11th.  Contamination was found on the bottoms of some of the pails and was removed, some of the contamination was difficult but not impossible to remove from the pail bottoms.

 The following targets have been moved from the spent target vault to the mini vault:

#127 - SiC#31 (front)

#132 - SiC#32 

#145 - UC#19

#150 - UC#20

#159 - UC#21 (back) 

Five spent targets have been moved from the Spent Target Vault to Mini Storage in preparation for transfer to F-308s in February. The following targets were moved Ta#35, Ta#39, SiC#27, UC#12, ThO#1

The following targets have been moved to the mini storage from the target storage vault:

1. Ta#38
2. Nb#7
3. TiC#3
4. SiC#29
5. NiO#2

These target will be removed from the mini storage and placed into the F-308's on December 3rd.

Spent targets in the mini storage were placed into the F-308s yesterday, all F-308 have been removed from the the target hall and they no reside for the time being in the hallway between the north and south hot cells.

UC#12 has been moved from the south hot cell and placed into storage. It is in pail #125 and in spot 1C of the vault it had a reading of 25.1mSv/hr upon removal from the south hot cell. See PDF for vault details.

SiC#31 has been moved to the spent target vault. It is in pail #127 and placed in spot 3C of the vault is was 489mSv/hr when removed from the south hot cell. See attached pdf for vault status

The spent ZrC#7 target has been moved from the south hot cell to the spent target vault. The target was placed in pail #129 and then placed in slot 3B of the vault, it was 157mSv/hr upon removal from the south hot cell.
