 The roughing pump was replaced with a more leak tight pump due to the discovery of Rn-220 migration while roughing on TM1 in TCS

Coil line has been in RPG's ultrasonic decon over night. Initial swipes this morning picked up 5000 counts. It has been decontaminated to the point no more contamination is being found and nothing can be found with the frisker...so...it's ready for Maico and Dan?

  990   Thursday, July 09, 2015, 14:02 David WangConditioning StationDevelopmentTM1 TM1 is pumping down at CS

TM1 and CS  vacuum system are connected. All turbo-pumps are started. The new TP1S works fine also. The pumping down looks good so far. During the TM1 and CS roughing down time, Joe .M noticed a Rn-220 level surge up in TH . Then,the Rn220  level slowly dropped back. Anders suspected this Rn-220 surging is related to the TM1 roughing down at CS. We decided we will stop the pumps , vent the CS , and roughing  again tomorrow. During the same time Joe will monitor  Rn-220 level in TH to see if the surging is repeatable. We want to learn more on this TH Rn-220 issue.

coil line has been removed from the hot cell. Initial decon was performed...after it still appears to have approximately 200 counts. It will now be transfered to the rad waste decon facility for further decon.

TM#2 has been moved from the south hot to the north east silo. TM#1 has been moved from the south west silo to the conditioning station.

  986   Wednesday, July 08, 2015, 14:48 chad fisherSouth Hot-CellRepairTM2 TM2 Status

Water block jig has been removed. Stuck source tray side water block jig component has been removed. An attempt was made to connect the gas lines to there bracket however they contact/interfer with the tube heater lines...Anders is looking into a solution.

Containment box and front cover have been replaced and TM2 is ready to move to the silo.

  985   Wednesday, July 08, 2015, 14:24 David WangSouth Hot-CellRepairTM2 TM2 pressure bubble test on RU water blocks.

July-06, 2015. Chad , Grant and I did the bubble test on R,U water blocks. We suspected the leak on the R,U circuit is from C seals on the water blocks so we did this test first. I applied both air and helium to R,U circuit , Chad applied snoop soap on the R,U water blocks.The air and helium pressure was increased from 40 psi to 90 psi Max step by step.Chad did not see any bubbles on the water blocks during the test. Since we did not find the leak source, we decided to do vacuum helium check on the all joints and c-seals of the R,U lines later.  Finally, We found the leak by vacuum helium spray the day after this bubble test. See other e-log.

  984   Wednesday, July 08, 2015, 14:05 David WangSouth Hot-CellRepairTM2 leak check coil line(R,U) on TM2 at SHC

Chad and I leak checked coil line(R,U) on TM2 at SHC yesterday. The leak detector was pumped down to 0.0Xe-9 atm.cc/sec before the check. Chad sprayed helium on the soldering joints connecting the cooling copper lines to the small holding blocks for the coil terminal(R,U).  After sprayed helium 2 seconds, I saw the leak rate on LD started to climbed up. The highest leak rate is 4.0xE-8 atm.cc/sec. It is a very positive response. We waited the leak detector pumped back to 0.0xE-9am.cc/sec, and tested again on the same joints. The result is same. Chad also sprayed helium on the R,U water blocks to check the C-seal. I saw a delayed tiny response on LD ( from 0.0 to 1.3xE-9atm.cc/sec). We think this tiny response is caused by the helium drifting to the leak soldering joint, but not a real C seal leak.

R U coil line removal started at 11:30. Water block jig installed and coil line disconnected from module.

CS TP1S had been replaced with a new TP-301 pump this morning.The old pump was broken last week.

Field measured at block "R" through tool port with pole monitor is 6.65 mSv/H.

There are three air hoods and two air lines currently available.

  979   Friday, July 03, 2015, 11:33 chad fisherSouth Hot-CellRepairTM2 TM2 Coil Leak Progress

First thing this morning the hot cell was "cleaned up" in preparation for the return of TM2 for attempted verification and locating of leak on R/U coil circuit.

Containment box has been removed and front cover reinstalled to provide some modicum of shielding form the entrance and exit windows. Box was placed at an angle in the corner to try and minimize line-of-sight with potential worker(s).

Did notice some funny discoloration of both sides of coil water block "R" as seen in attached picture.
