Spent target UCx#43 (pail 289) was moved from the South Hot Cell to the Storage Vault, placed in location 2A. Dose rate at 1m was approximately 22.6 mSv/hr.

Target index spreadsheet updated, attached.

 TM4 with new target UCx#42 was connected in ITE. 

 An electrical check was made after new target installed on TM4.

 TM4 with spent target UCx#42 was disconnected in ITE and has been remote moved to NHC this morning.

  TM4 with spent target UCx#42 has been electric checked at NHCpost right after transferred from ITE.

UCx #42 moved from North Hot Cell to Storage Vault in Pail #282. Placed in slot 6B. Tray 6 is now full. Pail measured at 34.9 mSv/h at ~1 m upon removal from the hot cell. See attached updated spreadsheet. 

 an electric check and leak check done on NHC, TM4 with new target UCx#41 is ready moving to TCS.

TM4 was moved from the North Hot Cell to the Target Conditioning Station with UCx#41.

 TM4 with UCx#41 was connected in ITE on Tuesday (2022-11-29) 

TM4 water lines helium pressure test was done yesterday at ITE. All water lines were air purged one day ahead  for the test. No leak  has been found on TM4 waterlines during the test. See attachment for detail

TM 4 has been disconnected in ITE.  See attachment for disconnection checklist.

TM4 electrical check with UCX41target and without target at SHC.  The results are good. See attachment.

ITE primary and secondary vacuum vessel air to vacuum seals leak check was done this week. One leak has been found on IG1S feed through to entrance module surface seal. It explains what we saw on ITE IG1S readings change(from low E-7 torr to 1Xe-6 torr) on December 22, 2022.  This leak seal will be replaced soon.

2023-Jan -27.  O-ring seal 229# was replaced on ITEIG1S feedthrough to entrance module surface sealing. Also o-ring seal 034# was replaced on the blank off cover beside the feed through to entrance module surface sealing. Since these o-rings are too close to each other. It is better to replace both of them to avoid misreading in leak check.

an electrical check was done on NHC, TM2 with new target UCx40 is ready moving to TCS.

Helium 70 psi. tested 5minutes at base leak rate 0.9 xE09 atm.cc/sec on HS line.  No leak.

 TM2 with UCx#40 is connected in ITW.

 TM2 with target UCx40 was disconnected in ITW and moved to NHC.

Starting at 11:00 am and finishing at 12:10 Ucx#4 previous target was removed and UCx#4 installed and leak checked on TM1.

During module move to the hot cell UCx#4 was housed in a bag under argon.

TM#1 with UCx#4 has been moved from the south  hot hell to the conditioning station. No problems with the move.

TM#1 with UCx#4 electrical check done at the conditioning station under vacuum, see attached sheet for results.
