I replaced all high active water system magnetic pedal wheels in ITW and ITE. This is a preventive maintenance job we planned for this winter shut down.

TM#1 has been moved from the south hot hell to the west target station, move went well.

I connected TM 1 vacuum system in ITW. The TM1 and ITW will be pumped out for shut down routine leak check.

2013 winter shut down ITW-TM1 primary vacuum vessel, secondary vacuum vessel, and water lines leak check: connected leak detector to TP2(primary and water lines) and TP4S (secondary). base leak rate 0.0xE-9atm.cc/sec,base pressure 0.0XE-4torr. Sprayed helium to all primary vacuum seal and there is no response on leak detector. Helium pressurized all water lines(except HS) at 70psi ,3mins.Tube heat(+) no response, tube heater(-)1.6xe-9atm.cc/sec, target oven(-)5.8xe-9atm.cc/sec, target oven (+) 6.9xe-9atm.cc/sec, EE 5.7xe-9atm.cc/sec, MSP no response, window 7.5 xe-9atm.cc/sec.All water lines are water leak free.  Two leaks had been found on secondary vacuum vessel. One is on exit 1 to tank o-ring (east side, E-N corner). The leak detector got   responses from 1.4 to1.7 xe-7 atm.cc/sec scale . The test  hadbeen repeated 4-5 times and   confirmed the location   . The second one is a small leak which  is on exit 2 to tank o-ring(east side, close to E-N corner). The leak detector got  responses from 1.4 to 1.8xe-8atm.cc/sec scale. The test had been repeated 3 times and confirmed the location. As the present plan. we will replace the exit1 to tank o-ring during this year shut down time.

Edi and I replaced the broken ITH MP1 in target hall with a new pump. The old pump was leak on oil. There were no oil had been left in the old pump by checking the sight glass.Thats the reason of  the pump  failure.The tray which the old pump sat on was full of leaking oil ( highly contaminated ). The old pump was bagged in 3 thick plastic bags ,and the tray was cleaned before the new pump was installed. The working area had been cleaned up and surveyed couple of times after the job. Everything is good. The new pump had been tested after the installation. It works fine.

Disconnected EXIT1 in ITW. All cables , wires and air lines are label marked.

TM1 moved from the west station to the southwest silo. Move went well.

ITW EX1 has been moved from the west target station to the south hot cell for the seal replacement on the west station.

TM1 has been reconnected in ITW. Water interlock check for TM1 is done.

I leak checked new installed ITW EXIT1 tank to module o-ring.No leak had been found . Also ,TM1 primary vessel air to vacuum seals had been checked at the same time. There was no response had been found on leak detector.

Water interlock check  on ITW is done. All water signals are strong on EL panel.  ITW is configured to take proton beam.

Dan and I  disconnected TM1 in ITW.

 I  reconnected TM1 to ITW on 02 July.The pumping down is good so far. TM1 water interlock check is good also.

5 shielding blocks had been  transferred from ITE to ITW.  The  ITW is configured to take proton beam.

TM#1 with UCx#7 has been moved from the south hot cell to the west target station.

I moved 5 shielding blocks to ITW this morning .I checked the water signals in electrical room before the moving, and everything is fine. The argon venting systemin ITW and electrical room is ready also.

TM#4 with SiC#29 has been moved to the south hot cell move went well.

 Yesterday I visually inspected the paddle wheel and noticed that it was spinning freely and constant. As the signal was intermittent replaced the coil at the back of the wheel only. This does not require access to the high active water. With the coil replaced the signal looked strong. I asked operations to keep and eye on it and advise if the problem has been resolved. I also discussed with David this morning and he informed me that this is the same procedure he would have followed.

TM#1 with UC#7 has been moved from the ITW to the south west silo.
