|
TM 1 is in ITW now. All connections are done. The turbo pumps had been started this afternoon. The vacuum looks good so far. The water interlock check
which related to TM1 are done. They are good. All TM1 water signals are visually checked and they are strong. The rest interlock check ( MCR
XT page) will be finished before shielding blocks moving. The MAA is locked and ITE is ready for proton beam. |

Thursday, September 20, 2012, 09:16, David Wang, Conditioning Station, Standard Operation, TM1, Nb#7, TM1 Nb#7 target heat shield helium pressure check is done.
|
Leak detector pumped down to base LR1.3xE-9 atm.cc/sec, and BP 8xE-3 torr. All high vacuum gauge readings at CS and TM1 are at low -6 range from 1.2xE-6torr
to 4.6x E-6 torr. Applied 80 psi helium to heat shield circuit for 5minutes and there is no any response on leak detector. The heat shield circuit
is leak tight. |

Wednesday, September 19, 2012, 11:23, Travis Cave, South Hot-Cell, Standard Operation, TM1, Nb#7, Electrical check
|
TM#1 with Nb#7 attached was electrically checked at the south hot cell yesterday, see attached pdf for details. Some notes about this test the oven to
the 60kV common is 2Mohm this was noticed on the target prior to installation on the module, and the 60kV common to chassis is low at 874Mohm (low as in
a non infinite value). |

|
Nb #7 was installed and tested today.
Inside face of the containment box cover was cleaned with methanol and a baseline picture taken in an effort to track deposits and marking as requested
bty Anders. |

Tuesday, September 18, 2012, 13:41, David Wang, South Hot-Cell, Standard Operation, TM1, Nb#7, leak check heat shield circuit
|
Chad and i did a leak check on TM1 heat shield circuit with new Nb#7 target installed. It took about 5 mins pump down the circuit to leak rate 0.0x
E-9atm.cc/sec and 0.0x E-4 torr on leak detector.
All vacuum lines and joints which connected to the leak detector had been helium sprayed and they are leak tight. Chad sprayed helium on |

Friday, September 14, 2012, 10:45, Travis Cave, Spent Target Vault, Standard Operation, , UCx#4, Spent target move
|
UCx#4 has been moved from the south hot cell to the spent target vault. The target was placed in pail #99 and now resides in spot 3C of the vault. It
measured 55.3mSv/hr at ~1m from the hot cell. See attached PDF for further spent target vault details. |

Wednesday, September 12, 2012, 11:59, David Wang, ITW, Standard Operation, TM1, UCx, TM1 disconnected in ITW
|
I removed 5 shielding blocks from ITW to block storage area, and disconnected TM1 in ITW. After UCx run, the radioactive level around the turbo
pumps and primary vacuum lines are pretty high. This affect the general field inside the ITW pit around working area.i took 15 minuts to finish the job
and i got 0.1msvr dose. the general field around my working area is about 350 usv/h. |

Wednesday, September 12, 2012, 07:00, David Wang, ITE, Standard Operation, TM4, NiO #1, ITM4 in ITE connected and pumping down
|
TM4 had been connected in ITE. Six turbo pump had been started . thepumpming diwn is very good so far. The water interlock check on ITE and TM4 had been
finished and everything is good.All water signals are strong and constant by visually checking. |

|
The spent UO#3 was moved from the south hot cell to the storage vault. It was in pail 98 and placed in spot 1A of the vault, the field measured upon
removal from the hot cell were 42mSv/hr. See attached PDF for vault details. |

See attached PDF for details. 60kV Common to the target is low at 343k but I've been told will work. Test will be done again on Friday after it has sat
a few days under vacuum. |
