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 each VCR joints for 2 seconds every time. During 45sec waiting time, there is no any response on leak detector. Chad repeated same test again for double checking and we got same result. Chad finally flushed the helium around the target heat shield for 10 seconds.we waited for 45minute and found no response on the leak detector. The heat shield circuit is leak tight at this stage. I will do a helium pressure test on this circuit when TM1 is in CS and under vacuum.

TM#1 moved from the south west silo to the south hot cell, move went well.

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.

TM#1 has been moved from the south hot cell to the south west silo. Move went well.

TM#1 with UCx#4 has been moved from the west target station to the south hot cell. Move went well.

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.

Electrical check of the TM#4 with NiO#1 was done again today. see attached file for results.

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.

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.

TM#4 with NiO#1 has been moved from the south hot cell to the conditioning station. Move went well.

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.

TM#4 with UO#3 has been moved from the east target station to the south hot cell for a target exchange. The move went well.

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 out beside the work area but nothing on the floor under the plastic that had been layed down for the job.

I disconnected TM 4 in ITE on AUG 29th morning.The vacuum lines stay untouched and they will be disconnected on SEP 04th.

Prob guys replaced broken air lines on ITW HARP 5B Cylinder.Several shielding blocks had been moved out to make the cylinder accessible. After the replacement,the HARP5B works fine.All shield blocks had been moved back to original position. The job is done.

I moved 5 shielding blocks from ITE  to ITW.ITW is configured to take proton beam now.

Connected TM1 in ITW,started 6 turbo pumps, and finished TM1 water interlock check . Every thing is good so far.
