|
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 |

|
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. |

|
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. |

Friday, September 07, 2012, 08:54, David Wang, Conditioning Station, Standard Operation, TM4, NiO #1, TM4 NiO #1 target heat shield helium pressure check is done.
|
leak detector pumped down to 0.0xE-9 atm.cc/sec, and 0.0xE-4 torr. All high vacuum gauge readings at CS and TM4 are at low -6 range from 2.2xE-6torr
to 4.2x 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. |

|
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. |

UOx was removed from TM4 yesterday and NiO#1 installed.
Video was taken.
Main stand-off insulators continue to deteriorate. |

|
Chad and i did a leak check on TM4 heat shield circuit with new NiO#1 target installed. It took about 40 mins(much longer than usual) to pump down the
circuit to leak rate 0.6x E-9atm.cc/sec and 0.0x E-4 torr o 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 each |

Entered south hot cell Wednesday and replaced the pre-filter air filter as well as the front two light bulbs. Also removed two bags of compressible garbage,
one bag of metal, and of course the bagged air filter (as Joe M. expressed as interest in havung it).
Inital checks found approximately 4000 cpm on the cell side of the temporary Al. panel used during the cell entry, 2000 cpm on the tacky mats layed |
