TM#1 with UCx#4 moved from the conditioning to the west target station move went well.

TM#1 with UCx#4 has been moved from the conditioning station to the west target station move went well.

 I replaced ITW TP4S today as we scheduled. The working area is swiped and air sampled .Everything is fine.

The Series # of the old pump is 200927, and the new one is 600080. The E-fault 6081 which is related to the job will be closed.

Ta#38 was moved from the south Hot Cell to the Spent Target Vault. Target is in pail #97, and was placed into tray 6 slot B of the vault. Field around the pail upon removal from the Hot Cell were 226mSv/hr at about 1/2 metre. See attached PDF for vault details.

Connected leak detector to TM1 and CS vacuum system. The vacuum readings on TM1 and CS:PNG4 3.6 xE-6 Torr, IG1 1.1xE-6torr, IG4(diagnostic box) 3.4xE-6 Torr. Leak detector base pressure:0.0xE-4 torr, base leak rate: 0.0xE-9 atm.cc/sec. Applied 80 psi helium to heat shield circuit for 4 mins . There is no response on leak detector. The heat shield circuit is leak tight.

TM#1 with UCx#4 electrical check done at the conditioning station under vacuum, see attached sheet for results.

TM#1 with UCx#4 has been moved from the south  hot hell to the conditioning station. No problems with the move.

Chad and i did a leak check on TM1heat shield with UCx target on.The circuit are pumped  down to the bottom leak rate and base pressure is 3xE-3 torr on the leak detector. There are two VCR caps on heat shield circuit. Chad sprayed helium on both of them   ( tested individually,2 seconds every time ) . The test repeated 1 time.There is no response on leak detector during 45 seconds waiting time on both time.Chad flushed helium around the target for 15 second. During 1 minutes waiting time , there is no response on leak detector.The heat shield circuit is leak tight at this stage. It will be helium pressure  in CS later.

Starting at 11:00 am and finishing at 12:10 Ucx#4 previous target was removed and UCx#4 installed and leak checked on TM1.

During module move to the hot cell UCx#4 was housed in a bag under argon.

TM#1 with Ta#38 has been moved from the west target station to the south hot cell, no problems with the move.

I disconnected TM1 in ITW.  Heat shield line has been purged .

  All water interlock checks for ITE had been done. The ITE water signals strength and frequency(Espcially on MSP circuit) had been checked from electrical room, and everything is good.

Today (Wednesday July 18th) at around 4:15 pm I was taking a small tour group from VECC into the Target Hall. In the process of discussing the mechanical design of the Target Modules and South Hot Cell turntable I inadvertently lifted the Aluminum Hatch Cover of the Hot Cell about 2 inches in an effort to explain something. This tripped the ventilation alarm before I realized what I was doing. I evacuated the visitors from the Target Hall, checked booties and gloves at the check station before having the visitors step over the boot box. I called operations and let them know what I had done. The Target Hall was locked out and is awaiting a survey for the morning of July 19th before work can proceed.

In the AM today David and I used the crane to raise the ground plate sheet metal into place. This afternoon when I attempted to return the crane to its usual place I discovered that the crane no longer worked. Upon further inspection it appears that the PLC has lost power. I will follow up on this Monday morning. The crane is not supporting any load at this point.

 Turns out I am just not very observant. David had turned the main break to the crane off as a result when he turned it back on this morning the crane magically started working again.

 TM4 has been moved to ITE and connected there today. I started six turbo pumps this afternoon. One of TP4 back valve (one in pairs) didn’t open .It caused the TP4 difficult to start. I disconnected that control cable that plug to solenoid valve and reconnected it. Then it works fine. After this, TP4 started to normal speed easily. The vacuum readings are OK so far. Tomorrow morning they all should be around 6-7 X E-6 torr range. Water interlock checks related to TM4 have been finished. NO water supply to ITE dump and entrance to keep the system pressure over 90psi. All TM4 water signals are good and strong by watching them from electrical panel. Gas line connected and valves opened. Control page set to fibiad .

TM#4 with UO#3 from the conditioning station to the east target station. Move went well.

Connected leak detector to TM4 and CS vacuum system. The vacuum readings on TM4 and CS:PNG4 3.6 xE-6 Torr, IG1 2.3xE-6torr, IG4(diagnostic box) 3.9xE-6 Torr. Leak detector base pressure:6.0xE-3 torr, base leak rate: 1.0xE-9 atm.cc/sec. Applied 80 psi helium to heat shield circuit for 5 mins . There is no response on leak detector. The heat shield circuit is leak tight.

SiC#27 has been moved from the south hot cell to the spent target vault. Target was placed in pail #96, placed in slot 3A, the fields at the hot cell were 178mSv/hr. For the latest on the vault see attached document.

Electrical check of the target was done at the conditioning station under vacuum, see attached file for details.
