I disconnected TM4 in ITE. The heat shield water circuit is purged. I  closed the water supply to ITE.Now, the water system only supply water to ITW and the system pressure is 110 psi which is good.I visually checked S-tank sight glass,and the water level is stable comparing to last week. Also, I visually checked the ITW water signals  strength and stability on electrical panel from electrical room.Everything looks fine.

Five targets were moved to the mini storage today in preparation for transfer of the targets to the F308s later next week. The moves went well. See the attached files for the vault and mini storage details.

  114   Monday, May 28, 2012, 13:05 David WangITEStandard Operation  I moved 5 shielding blocks from ITW to ITE .

5 shielding blocks have  been transferred from  ITW to ITE. ITE ventilation is opened, and ITW closed. All ITE water  signals have been checked for frequency and strength.They are all good. ITE is ready for taking proton beam.

  117   Wednesday, June 06, 2012, 08:21 David WangITWStandard OperationTM1 TM1 disconnected in ITW

I disconnected TM1 in ITW yesterday morning.The general radioactive level in ITW over the TM top (300mm) is about 350 usv/hr. contacting level on TP1 and TP2 are 1.0-1.2 msv/hr. I took 0.22 msv dose .The module is moved to

south hot cell later and a shielding plug is put back to ITW. Everything is fine.

  134   Monday, June 25, 2012, 14:39 David WangITWStandard Operation  I moved 5 shielding blocks from ITE to ITW,

and set up ventilation for ITW. ITW is ready for taking proton beam now. All water interlock checks for ITW are done. The ITW water signals strength and frequency had been checked from electrical room, and everything is good.

  135   Tuesday, June 26, 2012, 14:10 David WangSouth Hot-CellRepairTM3 TM3 heat shield and window circuits leak check is done.

Chad and i did a leak check on TM3 heat shield and window circuits.Both circuits are pumped easily down to the bottom leak rate and base pressure 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 ) . There is no response on leakdetecor during 45 seconds waiting time. On window circuit there are 2 VCR joints. Chad sprayed helim on these joints(2seconds for each), and no response on leak detector. All joints  are double checked(sprayed twice on each of them). The result is they are leak tight.

  136   Tuesday, July 03, 2012, 10:50 David WangITEStandard OperationTM4 Disconnected TM4 in ITE.

I disconnected TM4 in ITE this morning. The window circuit and heat shield circuit had been purged. The general field inside ITE is about 200usv/h.

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.

  148   Wednesday, July 18, 2012, 16:49 Grant MinorSouth Hot-CellDevelopment  South Hot Cell Ventilation Alarm Trip

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.

 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.

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.
