  815   Friday, December 05, 2014, 13:46 Anders MjosConditioning StationDevelopmentTM2 Not able to start water system

 TCS:WPV1 does not open when staging is enabled. Multiple attempts have been made, but the valve remains closed.

  814   Friday, December 05, 2014, 11:58 David WangConditioning StationDevelopmentTM2 helium pressure test on TM2 tube heater +(D) water lines.

At CS, The leak detector is hooked directly to the TM2 top service cap. The base LR 0.0xE-9 atm.cc/sec, base pressure 0.0xE-4torr. Applied 80 psi helium to TM2 tube heater +(D) line . During 3 minutes applying time , I did  not see any tiny change on LD readings. The line is perfectly vacuum sealed.  See attachment pictures.

  813   Friday, December 05, 2014, 07:47 David WangConditioning StationDevelopmentTM2 TM2 at CS

The pumping down on TM2 at CS was good overnight. However, the back up line pressure is still too high for LD to get to 0.0-E-9atm.cc/sec . It only could get to 1.2xE-7 atm.cc/sec. It is not enough for a good leak check . I dont want to have any ambiguous situation on this" D" line leak check. So,I am going to reconfigure the leak detector to the spare KF25 pot on the TM2 service cap. All pumps are stopped . The CS and TM2 will be vented soon. After that, a manual valve will be installed on that spare KF25 pot for future helium pressure check at CS. Then, The TM2 and CS will be pumped down again.

  812   Thursday, December 04, 2014, 16:37 David WangConditioning StationDevelopmentTM2 connected TM2 and CS vacuum system .

I connected TM2 and CS vacuum system. All vacuum pumps on TM2 and CS are started .The pumping down is good so .far

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.

  808   Tuesday, December 02, 2014, 13:33 David WangSouth Hot-CellDevelopmentTM2 Leak check on TM2 tube heater +(D) at SHC

Chad and I leak checked TM2 tube heater+(D) circuit at SHC with water bypass loop and new seals installed on the water block. The LD base LR 0.0xE-9 atm.cc/sec,base pressure0.0xE-4 torr. Chad sprayed helium on the leak check area in SHC for 5 seconds. No any response has been found on LD during 1minutes waiting time. The test was repeated again and the result is same. NO LEAK at this stage!  After the TM2 is moved to CS , The D line will be pressured with 80 psi helium for helium pressure leak test before any hot water is circuited through it.

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!

  800   Tuesday, November 25, 2014, 11:33 David WangSouth Hot-CellDevelopment  Remove UCX 11 target transfer stand from SHC back to TH.

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
