TCS and Tm1 vacuum pumps are switched off this morning. TM1 TP1and TP2 work fine during this test period. Tm1 will be moved back to silo this morning.

TM1 IG1 stopped work during the test period. It could be broken. We will only replace this gauge if TM1 is used in ITW again.

 TM#1 has been moved from the north west silo to the conditioning station for the day it will be moved back to the silo tomorrow morning.

TM1 shielding plates and their holding bolts are inspected. No corrosion.  TM1 is located at TCS now. Both TP1 and TP2 are started.

 TM#1 has been moved from the south hot cell to the northwest silo.

Ta#35, in pail #88, has been place into spent target storage, in spot 6C. Upon removal from the South Hot Cell it was 411mSv/hr our hottest target to be placed into storage to date. There are 8 free slots for targets left in the vault.

Ta#37 has been moved from the south hot cell into the storage vault. The target is in pail #89 and in spot 6A in the vault. It was 840uSv/hr upon removal from the south hot cell. There are 7 free spots left in the vault.

The spent Ta#36 has been moved to the storage vault. It was placed in pail #90, and placed into slot 3B, it was 111mSv/hr upon removal from the south hot cell. There are 6 free slots left in the storage vault.

The spent UCx #2 target has been moved into storage. It was placed in tray 5A and is in Pail #91, it was 8.91mSv/hr upon removal from the south hot cell. There are 5 free slots left in the storage vault.

For the week of November 7th 2011, four of a possible ten targets that are in storage were assayed. Targets are as follows:

Target             General average field @ 1 metre from edge of pail

SiC#24           1.99 mSv/hr

Nb#4               3.89 mSv/hr

Ta#25              4.57 mSv/hr

Ta#37              0.47 mSv/hr

These four are all viable spent targets to be shipped. We still need another couple of days of "UNINTERRUPTED" time to assay the remaining six targets, for us to have enough to make a ship of five to Chalk River.

TaC#1 was moved from the south hot cell to the storage vault. It was placed in pail#92 and put in vault slot 7B. It was 239mSv/hr upon removal from the south hot cell.

Spent target assay completed. A total of 16 target were looked at, 13 were low enough to be assayed and those 13 are at shippable levels, the other 3 of the 16 looked at were too hot to ship and assay. See attached pdf for complete details.

Well the first of this year's lucky winners to win a fabulous one way trip to Chalk River are as follows. UC#1, UC#2, Ta#25, Ta#26, and Ta#37. First these lucky winners will get to stay several days and night in the lovely all inclusive mini vault before being loaded in to their very own private F-308 flasks to be whisked away off to fabulous Chalk River.

Looks like the UC target s #1 and #2 were found invalidprize winners for their all inclusive trip to Chalk River and have thus been placed back in to storage for the next draw. In their place a pair of lucky Ta targets won, seems to be Ta lucky draw this year, Ta#28 and #29 have been placed in the mini storage for several fabulous day and wondrous nights, before being whisked away on their all inclusive one way trip to Chalk River. See attachments for the status of both vaults.

Hi Remote Handling,

The guage on the IMC circuit in the Target Hall is reading atmosphere, and the bellows is currently relaxed (i.e. expanded), whereas it should be reading about -20inHg and the bellows should be contracted (i.e. compressed).

I've attached a photo of what the guage and fittings should look like when pumped down to -30inHg.

Either the IMC circuit has been vented, disturbed, or it has some kind of leak.  When I was in the Target Hall this morning, I saw the gauge bent around the railing at an awkward angle with a pretty severe bend in the copper line, it appeared to have been disturbed by the temporary glove box sitting at that level used by Rob Walker for nuclear ventilation work.

I will co-ordinate pump-down and leak check of the circuit, but the Conditioning Station cannot be used until this is repaired.

Cheers,

Grant

All targets in the mini storage have been moved to F-308s and those flasks have been moved over to rad waste. The transfer of target occurred on January 10th and the flasks were moved to rad waste on January 11th.  Contamination was found on the bottoms of some of the pails and was removed, some of the contamination was difficult but not impossible to remove from the pail bottoms.

I had changed all old induction coils for flow sensors in ITE .I checked all ITE water signals on control boards in electrical room.They are all very stable and constant.All ITE inductions coils work fine now.

I pumped down conditioning station IMC today. The inside bellow pressure is -20 psi on the gauge.Visually checked the bellow before and after pump.The bellow is in retracted condition now.

I did a leak check on conditioning station vacuum system today.The vacuum system had been roughed over night . This morning before the leak check,the convectron gauge  reading on emittance box is 20m torr which is reasonable. I hooked the  leak detector to system (without turbo pump  on) . The leak detector showed base LR 6.3xE-8 atm.cc/sec. At this base LR, I found 2 leaks up to low E -6range on that cross tube flange to small turbo pump, and the cross tube flange to vessel. I found some of the bolts on the flanges could be tightened more ½ to ¾ turn without difficulty. I checked all the fasteners on the box, cross tube, and turbo pump, tightened some of them. By doing it, the base leak rate dropped to 3.0x E-8 atm,cc/sec, base pressure still 0.0XE-4 torr. I sprayed helium again, the response I found before now disappeared. I waited for about 1hour, and let the leak detector base leak rate dropped to 1.3 xE-8 atm.cc/sec, and base pressure still at 0.0xE-4 torr. At the same time, i only use leak detector as back up pump for whole sysytem and shut off the valve to the scroll pump.By doing this , the leak detector is much stable on the base leak rate. With the help of Bevan, i sprayed the helium to all the vacuum  equipments again.This time,no any tiny response has been found on leak detector.The leak rate stayed at 1.2x E-8atm.cc/sec, and no change on pressure also. I checked helium bubble several times during the spray. The conditioning station vacuum system is leak tight.

SiC #26 was moved from the south hot cell into storage today. The target was is in pail # 94 and was placed in slot 1B in the storage vault. The fields of the pail at the hot cell were 118mSv/hr upon pail been removed from the hot cell. Attached is the current status of the storage vault.

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.
