ESC came today and "repaired" the chiller. There was something wrong with the VFD controller. The were able to get it to start and run correctly again but were not able to recreate the problem. At this point it appears that it has magically disappeared. 

 Rob Walker has drained the primary side of the conditioning station. It will be flushed, filled  and chemically treated. It was desired to chemically treat the primary side before before but it took so long that sediment was found (things started to grow).

The special tool made for the RFQ target autopsy has been inserted into the hot cell.

4-40 button head screws have been successfully lossened.

 Once again the 7.5 compressors are tripping due to faults. I believe it is due to over pressure as a result of the chiller fans not coming on. I have contacted ESC.

 During HV conditioning of TM4 with Ta#40 there was a spark at ~43 kV that caused the Bias card to "fry". Dave Morris has been contacted and has said he will replace it tomorrow.

Major portions of the RFQ target have now been sucessfully dismantled. More minor dismantling with conclude this afternoon.

Spent target SiC#28 (RFQ Target) has been moved from the south hot to the storage vault. The target was placed in pail #105 in spot 2C of  the spent target vault. The target had a field of 24.8mSv/hr at about a meter upon removal from the south hot cell. See attached PDF for the status of the vault. It currently only has six free spots left.

ESC was called out again to inspect the chiller as it was showing the same problem as before. This time when started one fan came on (this is not what happened last time) but the fan controlled by the VFD did not. It was eventually traced to a relay that has been replaced. The system was tested as best it could without a load and appears to be working. It will be difficult to tell until a heat load is in place if the fix has solved everything. 

The spent source tray for TM#3 has been removed from the south hot cell and well be placed in the the hot cell ante room. To sit till maintenance day to be moved over to the vault storage tunnels.

the warm cell mock-up has been inserted into the warm cell and final preparation for the remote test are being made.

Ten targets have been assayed or had field measurements(they were too hot to ship but were assayed the last time an assay was done) done on them  over the past two days. Of those that have been assayed we have total of ten shippable targets. See the attached PDF for the latest details of the storage vault.

The polishing/cleaning tool prototype is now finished and appers to work great.

Thanks to Dan and Maico for the great job making my design a reality.

Ta#39 has been transferred to spent target storage vault. Ta#39 was placed into pail #106 and placed into spot of 4C of the spent target vault. The pail measured 95.8mSv/hr upon removal from the hot cell. See attached PDF for details.

to reduce the radioactive shining from  SHC Ta# 40 target.

Spent target Ta#40 has been placed into storage. The target was placed in pail #107 and was put into slot 5A of the vault. It had a field of 224mSv/hr upon removal from the south hot cell. See attached PDF for more details.

Five spent targets have been removed from the storage vault and placed into the mini storage. The target placed into the mini storage are UO#3, UC#'s  3,4,5 and SIC#23. See attached PDFs for vault details.

All the F-308's have been torqued up  and the locks installed. Ready to be moved.

Spent target move, UC#6 has been moved from the south hot cell to the target storage. The target is in pail 108 and in slot 8C of the vault. See attached PDF for details.

 The right manipulator A-9885 Handle Cable Assembly has been repaired by Maico and myself. We repaired the manipulator following some verbal instructions from Chad on the modified repair strategy. This allows the repair to be completed without going into the hot cell. The instructions in the repair manual are very vague and can actually cause problems. For example it is best to pin the manipulator before completing any work. Other than that the work went smoothly with the exception that the counter weight hangs up on the manipulator occasionally and can cause the cable to come off of the pulley. Also it appears that the left manipulator has had the cable installed incorrectly as it rides on the housing of the wrist.
