  1129   Tuesday, November 24, 2015, 13:54 chad fisherSouth Hot-CellRepair  Cell Decon

Decon/removal of large solid waste was performed on Wednesday November 18th."Hot" activated items included containment box cover from TM2, Febiad coil line remnants from TM4 (the hottest ends were previously cut off and disposed of), some target conductor bolts, steerer plugs from TM2, target material remn.

Drum containing these solid items is 2.5mSv/hr at 1/2m.

Drum is stored in the north hot cell temp.

Compressible waste will require another drum.

Swipes were taken of the window... 170k counts per minute of cont.

Residual fields from the remaining compressible waste were still too high (as far as I'm concerned) so I have unpacked all compressible waste looking for a "hot" item that has snuck into these items.

I have a hand full of small bolts (possible target components), a hand full of target material/dust (including an entire target disc), and some cloths that had clearly been used to wipe the table (they are black with target dust).

These items will be disposed of with the next spent target.

electronics package on left manip died completely yesterday (it has been going for a while).

Disconnected entire package and replaced with package from "spare" manipulator.

everything is back up and working.

Another drum of waste was removed from the south hot cell this morning. This drum contained one 5 gal steel pail (damaged), two sodium light bulbs, airlines, and tank suits. Upon removal the drum was/is 1.5 mSv/h on contact. there was 200 counts of contamination found on the lid...easily removed. It will be moved to the north hot cell at 11am.

SiC#32 has been removed from TM2. Quick inspection shows some troubling discoloration on the water cooled connection blocks of C and D as well as the left target heater A.

As for the target, both legs are broken and is has the normal "charge up" marks on the 9 pin connector.

  1168   Thursday, March 17, 2016, 14:57 David WangSouth Hot-CellRepairTM2 TM2 first round leak check in SHC

Chad and I finished the first round check on Tm2 water lines. The lines and spots checked are: Target oven + and - (front side braze joints) , Tube heater+and -(front side braze joints and water blocks), coil2 and coil 1(front side braze joints and area close to water blocks),. No leak has been found on all above of them.  The last, we checked   the GE which has the biggest leak so far. The leak detector base leak rate only can get to 4XE-9 atm.cc/sec. Chad sprayed helium very close to GE water block, and I got a quick response on leak detector. The leak rate climbed from 4Xe-9 atm.cc/sec to 1.4 atm.cc/sec. We confirmed the GE is leaking now. The exact location need to be pinpointed later once the containment box is out after the module is back to SHC. The module will be moved to TCS tomorrow morning and pressurized again there. Anders will use RGA to monitor the helium response during the check.

  Chad and I did the helium spray leak check on TM2 GE and MSP water lines at SHC this morning. We confirmed the GE leak on water blocks. We can not found the MSP leak by using the helium spray since its leak rate in TCS is much smaller than GE leak.  The leak check process are as below:
Leak detector are calibrated before the check.
GE lines : Base leak rate 0.0 X E-9 atm.cc/sec, base pressure 0.0 XE-4 torr.
Chad sprayed 5 psi helium to GE lines soldering joints  for 5 second, no response on leak detector.
Chad sprayed 5 psi helium to GE lines water blocks( between blocks seal surface) for 5 seconds, Leak detector response to 8 XE-9 atm.cc/sec right away.
Chad sprayed  5 psi helium to GE lines soldering joints for 5 seconds again, No response on leak detector.
Chad sprayed 5 psi helium around the source tray and to vacuum duct for 5 seconds more, No response on leak detector.
MSP lines: Base leak rate 0.0X E-9 atm.cc/sec, base pressure 0.0 X E-4 torr.  Chad did same thing as he did on GE lines. no response on LD. Chad repeated the test and prolonged the spray time to 10 seconds, No response.
The conclusion: It is pretty clear we have a leak on GE line water blocks seal.  MSP lines leak could not be found by helium spray in SHC since it is a small leak.
