Some issues with the turntable and having to wait for a decision on whether to remove TM2 from the hot cell so that TM4 with dead UCx target could be put in this morning.

Progress on TM2:

• Containment box has been removed from TM2.
• Water block jig has been installed.
• Existing blank off has been removed.
• Sealing surfaces have been inspected.
• First stage of sealing surface cleaning has been performed.

Tomorrow:

• Polish of sealing surfaces.
• Installation of loop.
• Vacuum/helium leak check of loop.

TM2_20141201_03 - sealing surfaces before cleaning...kind of dirty

TM2_20141201_05AC - sealing surfaces after cleaning...looks good!

F-308's have been serviced and are ready to be filled with spent targets. F-308's witch were serviced are #6,#13,#15,#16,and #19.

TM#2 with no target or source tray has been moved from the north east silo to the south hot cell.

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.

5 Shielding blocks have been transferred from ITW to ITE. The ITE is configured to take proton beam.

The stand was used for transferring UCX11 targte from TH to SHC. The stand wit target was craned down from TH into SHC last week and stayed there over weekend. Chad and I removed the stand out of SHC yesterday. It was heavily contaminated. RPG and I spent more than 3 hours to clean this stand. See the emails I pasted below for  detail information.

Thanks, David, for letting me know about this. Here are survey results after my afternoon in Target Hall:

I spent 1.5 hours on additional decon of the stand, crane hook, and area around where David was doing the decon, finding up to 10k cpm (44-2) on some parts at first. Danka came to help after a bit (THANK YOU, DANKA) and we left the items covered in plastic and surveyed the area. Contamination survey results are as follows, numbers are units of cpm on the 44-2/RM14:

Tacky mats inside TMH door: 6000/2000

Tacky mats in hall before TMH door: 200/0

Tacky mats at boot box: 8000/4000

My booties: 50/0

Air sample at the decon area: 50/60 (also 100 cpm on alpha probe)

Floor swipes post-decon of floor: 0/0

Early results from a 10 min assay of the tacky mats shows predominantly Kr-85, Be-7, Sr-85, Rb-83, and Sr-82. A longer assay is underway.

The following measurements were made using the checking cave at the boot box (units of cpm):

David's respirator cartridges: 160

David's respirator: 0

Davids tank suit and booties: 1200

My suit: 100

My respirator: 0

The rags used for the decon work were contained in a bag and left behind the silos by the DST. This bag measured 240 uSv/h OC and 2 uSv/h at 0.5m

Thanks,

Andrew

Hi all, The UCx#11 target transferring stand is moved back from SHC to TH. However, the stand was heavily contaminated. On the first Windex clean up towel, the counts directly shoot over the 500K counts which is the maximum scales on both RM14 and 44-2. After almost 2 hours, more than 20 times cleaning up with Windex spray and paper towel wipe , the counts dropped below 300 now. It is extremely difficult to clean up this stand.  I dont think we should move the target this way again unless we have a solution on the contamination clean up. The stand is still hanging  on the crane, and waiting for RPG checking.                        Thanks    David

The spent Ta#44 target has been removed from the south hot cell, it was placed in pail #121 and placed in spot 4A of the storage vault. It was 276mSv/hr upon removal from the south hot cell.

CS and TM4 was vented with Argon gas this morning before it was moved from CS to ITE.

TM4 has been connected connect in ITE. Water is supplied to TM4 module only.

TM#4 with UCx#11has been moved from the conditioning station to the east target station.

CS roughing pump is started for TM4 and UCX 11 target.

TM#4 with UC#11 electrical check done. See attached PDF for the results.

Ta#44 has been removed from TM4 and UCx#11 has been installed and is ready for testing.

New fasteners were installed for all mounting and current connections.

High current fasteners were torqued to 130in lbs.

Dan and I disconnected TM4 in ITE.

I craned down UCx11 target from TH into SHC. Chad was in SHC service area watching on it. The source tray moving jig was installed on the crane for this moving.

TM#4 with Ta#44 has been moved from the east target station to the south hot cell.

Jig for installation of target through hot cell roof has been assembled and placed in the target hall.

TM#3 with no target has been moved from the conditioning station to the north west silo.

Dan and I replaced flow wheel on ITE HVC2 water flow sensor. The old wheel did rotate smoothly inside its SST case. The new wheel works fine.

I replaced flow wheel and coil on ITW MSP water flow sensor which is located in ITW pit. Before replacement, I checked the signal strength and frequency form e-board on this circuit. The signal was good in 10minutes watching. Still, I replaced them. The flow sensor works fine after replacement. I made a comment  on Isac e-fault system about this issue.
