Cell (table) was systematically cleaned with a swiffer and resulting piles of contaminated waste placed in pail with spent Ta target.

Entry  Wednesday, December 02, 2015, 10:41, chad fisher, South Hot-Cell, Repair, , , Drum Clean-up #2 

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.

Entered the hot cell to perform final decon on the window. Initial swipes this morning were 11000 c.p.m. on 44-2. After decon approximately 100 counts.

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.

Entry  Thursday, March 17, 2016, 14:57, David Wang, South Hot-Cell, Repair, TM2, , 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.

SiC#32 has been open for inspection.

TM#2 was moved into the south hot cell by 08:30.

Entry  Wednesday, March 23, 2016, 11:32, David Wang, South Hot-Cell, Repair, TM2, , TM2 Helium spray leak check on GE and MSP lines at SHC 

  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.

Entry  Monday, May 09, 2016, 10:13, Travis Cave, South Hot-Cell, Standard Operation, TM2, no target, module moved 

TM#3 was moved from the conditioning station to the NE Silo. TM#2 was moved from the SW Silo to the South hot cell.

Entry  Tuesday, May 10, 2016, 13:37, chad fisher, South Hot-Cell, Standard Operation, TM2, Ta#48, Ta#48 Installation 

Ta#48 has been installed onto TM2. Also new window gaskets were installed.

High current fasteners were torqued to 130 in lbs. Shutter side of the containment box recieved new fasteners.

Entry  Tuesday, May 10, 2016, 13:54, David Wang, South Hot-Cell, Standard Operation, TM2, , SHC, TM2 leak check on window line and HS line. 

Chad and I leak checked the TM2 HS and window lines after new target installation.  The window line was very easy pumped down on LD. But, The HS line only could pumped to 2-3 torr at first. Chad changed the VCR gaskets on HS line(target). It solved the problem. The LD could pumped  both of Window and HS lines to the bottom scale. Chad sprayed lots helium around the VCR joints.  No leak has been found. WE will do helium pressurizing test on them at TCS.
