UCx#2 has been removed from Tm1 and put in a bucket with a slow argon feed and a lid placed lossely on top.
TaC#1 ITW has been installed and is awaiting testing at the cell. |

Thursday, August 18, 2011, 14:09, Bevan Moss, South Hot-Cell, Standard Operation, TM1, UCx#2, Leak and Electrical Check plus Remote Move to Conditioning Station
|
TM1 with UC#2 had the target installed, the heat shield line was pumped on and achieved a vacuum of 0.0 x 10^-4 Torr and a leak rate of 0.0
x 10^-9 atm cc / sec with no response when sprayed with helium. An electrical check was completed by David and myself all values were withing tolerance.
The module was then moved from the south hot cell to the conditioning station where it will start pump down. The move was uneventful every operated |

Thursday, August 18, 2011, 16:07, Bevan Moss, Conditioning Station, Standard Operation, TM1, UCx#2, Pump Down
|
Pump down in the conditioning station started at ~2:40 for rough down. The turbo pumps were turned on at ~3:30 and at 3:52 the pressures were reading
as follows:
IMG in the containment box 9.2 x 10^-5 T |

|
A leak check was performed on the module when it was in the conditioning station today. There were no external leaks
found. When the coolant lines were check a small leak was found in the heat shield circuit. Base leak rate was 6.7 x 10^-9 atm cc /sec and rose to 4.1
x 10^-9 atm cc /sec quickly (~3 seconds) and remained there for the 2 minute test. The remaining lines |

|
On August 22nd TM1 was vented with Argon in the conditioning station. It had been pumping with just the roughing pump over the weekend so the UCx#2
target would not be exposed to oxygen. The move went without incident and took roughly an hour to complete. Once at the hot cell the panel was removed
by Tom Lyth and a leak check completed with Bevan, David Wong, Grant Minor, and Tom Lyth present. The connections to source tray were checked starting |

|
Today a leak check on TM1's external seals and the heat shield line was completed by David Wang. After 16 hours of the turbo pumps running on the conditioning
station stations pressures were 3.6 x 10^-6 T, 1.2 x 10^-5 T, and 1.8 x 10^-6 T for the containment box, secondary vacuum, and service cap respectively.
This is a significantly quicker pump down after the cross with small turbo pump was installed on the vacuum vessel. The base pressure of the leak testing |

Thursday, September 01, 2011, 09:11, Don Jackson, ITW, Standard Operation, TM1, UCx#2, Argon Venting West Station
|
West target station is setup to use argon for tank venting. There is 1200 PSI remaining on argon bottle in electrical room. That is sufficent
for venting west target station to atmosphere twice. ISAC Operations has been previousily contacted and their procedures for venting remain the same
except that they can not rely on ITW:CG4S to determine when at atmospheric pressure. I have asked them to contact me if an unscheduled vent is required. |

|
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. |

Monday, January 22, 2024, 10:16, David Wang, ITE, Standard Operation, TM4, UCx#, Tm4 waterlines helium pressure test and TM service cap helium leak check.
|
Tm4 waterlines helium pressure test and TM service cap helium leak check was done last Friday. All water lines were pressurized with 70psi helium for
3 minutes each. The 3 minutes stable leak rate on all lines are less than 4.0 X E-9atm.cc/sec. some of lines had surging leak rate to 2xE-8 atm.cc/sec
at the first 10 seconds of pressurization which should be a gas hammer result at the beginning. Based on the numbers, I would say all water lines are leak |

|
Chad and I did leak check on TM2 HS line at SHC yesterday. Base LR 0.0XE-9 atm.cc/sec. No response on LD. during helium spray.
Today , I did helium pressure test at TCS. base LR 0.0xe-9atm.cc/sec. applied 70psi helium for 3 minute. leak rate slowly climbed to2.2 Xe-7 atm.cc/sec
ate stopped there. The result is close to before. |
