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.

  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.

 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.

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

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

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.

ITE MSP water circuit flow wheel was replaced yesterday due to poor performance.

Grant and I replaced the conditioning station broken  srcoll pump with a refurbished scroll pump which is supplied by vacuum group. The replaced pump is bagged and waiting for RPG further survey in target hall . The target hall is survey after the job, and everything is fine.

Bevan and I transferred five shielding blocks from ITW to ITE. ITE is ready for taking proton beam.

The F-308 have been cleaned and serviced. There were three F-308's that came back with some contamination.#13, #15 and #19 were found to have contamination. They were decontaminated. All of the loose contamination was removed. There is still some fixed contamination. The levels of contamination are low enough to still be used for shipping spent targets. They have been moved to the north hot cell area and are ready for to be filled with spent targets. 

This week six targets and the two source trays were assayed and surveyed from the storage vault. see attached PDF for details.

Attached are pre-removal pictures of NB#7 and the inside face of the containment box cover before cleaning.

I connected TM1 in ITW yesterday. Everything is good so far. Travis was with me when i did the job.

I changed ITE dump water circuit flow wheel due to its poor performance. The new flow wheel works fine. The signal on electrical board is strong and constant. One shielding block on ITE was moved out for the job, and it has been moved back after the job.The ITE is ready to take proton beam. Travis was with me when i did the job.

Five spent targets have been moved from the storage vault to the mini storage vault. The five targets are as follows: SiC #25, Ta #34, Ta #32, Ta #31, Nb #4. See the attached PDFs for full details.

On Nov 20th the 5 targets in mini storage have been moved to the F-308s, those F-308s have since been moved to the hot cell ante room. They will sit there until Monday.

I moved 5 shielding blocks from ITW  to block storage area for preparing the TM1 disconnection. Air sampled and swiped blocks and ITW and everything is fine.Fiona was with me all the time during the moving.

TM1 has been disconnected in ITW. All  water lines had been purged. Travis was with me during the job.

I replaced all high active water system magnetic pedal wheels in ITW and ITE. This is a preventive maintenance job we planned for this winter shut down.
