  963   Friday, June 26, 2015, 09:44 chad fisherSouth Hot-CellRepairTM2 TM2 Retrofit Status

On June 25th the following work was completed:

Optics tray was installed into TM2. The lower fastener on the vertical cable tray (IRH1585) needed to be removed and vertical cable tray rotated upwards as optics tray would not clear cable tray. Optics tray was intstaled, cable tray repositioned and screw re-inserted.

Modified water block for 9 pin connector was installed.

Steerers connected.

Ground Electrode water blocks were "repositioned" closer to there specified position to attempt eliminating the short between the ground electrode line and coil 1 circuit. This was successful but could still use a clamp or other method of ensuring the ground electrode line is in its "proper" place.

9 pin connector line was rerouted to ensure it does not contact anything it is not suppose to (Rerouting directions provided by Anders).

Enzel lens cable was installed.

Blank offs removed from window water lines and new gaskets installed in preparation for installation of the containment box.

There is an air to vacuum leak on TM2 service cap side panel which we moved out during the TM2 wiring job. The CS pumps are stopped now. The CS will be vented soon. The seal on this panel has to been changed.

2016-06-30.  The o-ring seal on this panel(PNG1 and steerers)  is replaced and leak checked. No leak now.

 I leak checked TM2 at CS this afternoon which including air to vacuum check on service cap and helium pressure test on water lines. There is a small leak on water line R ,U (COIL1) during the helium pressure test.. Below 20 psi helium, there is no leak on it. But , once the helium pressure is increased over 20 psi, it showed up on Leak Detector. At 60 psi helium, the leak rate is 9.4xE-9 atm.cc/sec. For detail information, See attachment.  All other water lines and air to vacuum seals are good.

  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.

  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.

  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.

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.
