UCX34# in pail 258(Vault lot 7C) has been repacked today. It is an investigation to find a possible leak source of radioactive Iodine in vault. The new pail number is 268. It is back to vault 7c . I wrote down the information in log book. The job is smooth today. I retrieved UCx 34 old pail and liner to TH. The liner from UCx#34 only has 3000 counts.  I bagged it. It could be used later. However, the pail has 500K counts contamination on bottom outside rim. It may accidently be slided out of plastic bag and touched the NHC table during the repackage. I bagged it and store it in silo area. When we do drum clean up, I will throw it in the drum.

 A 3/8 inch drain valve on return cooling line was replaced in ITE. In the meantime two 1/2 inch valves labeled FEBIAD COIL and ENTRANCE COLLIMATOR RETURN at ITW were replaced . The 2 inches leaky supply/return water valves in ITW were repaired as well. Pls check pics

attached here for detail.

 The valves #V10 & V11 beside high active water pumps were replaced in Target Hall, pics attached.

Carla did the test. That is what she wrote in Feb 04th:  "I am done with the HV testing at ITE - the results were the same as at ITW. It stayed at 59kV for 30 mins with no issues. Trying to go above 59.5kV is probably possible but a bit more risky. ITE also has a band, from 54-56kV, where the current jumps around like crazy".

  Carla did the test. and reported the result as following: HV testing of ITW is complete. It was pretty well behaved up to 59.5kV, and sat at 59kV for 30mins with no sparks (that EPICS caught). There was some strange behaviour of the current between 51kV and 53kV - it was jumping by 20uA or more - but there didn't seem to be any voltage response, and it went away after 53kV (though it returned on the way back down). The test was done in Feb 02.

Spent target UCx #33 has been repacked with a new pail and lid in NHC. Old pail #255. New pail # 267. Location: Vault slot 1C.  it is an investigation job for  a possible leak pail in vault.  

Tom Kauss finished target hall overhead crane annual inspection today. The crane works fine. He issued new inspection tag and e-logged the job. 

Two shielding blocks  above vacuum station at TH west end were opened for inspection. Checked ITH:MP1, MP2 lubricant color and level through sight gauge on pumps. They are still ok.  Restored the shielding blocks.  Checked ITM:MP1 by decay tank (Mirror checked  sight gauge by north wall). Added lubricant to ITM:MP1 to middle level on sight gauge.  

ITE/ITW  are cleaned with vacuum canister. HV  cage inside and blue nylon insulators are wiped.  Garbage inside the pits are cleaned out.

TH emergency exit hatch which is located on TH west end roof is opened and closed for functional check. The hatch works fine. The limit switch on hatch is in position. No obstacle on hatch way to the roof. 

The spent Ta#63 has been moved from the north hot cell to the spent target vault. It was place in pail#266 and 
placed in spot #3B of the vault. see attached PDF for more details.

TM4 was removed from NHC to S_W silo yesterday.  The remove is smooth and successful.

Tom Kauss inspected target hall crane below hook attachment pins and plates ITA6550-01. He certified the use of these pins and plates. The inspection of these pins and plates was in Target hall crane annual check list. It was issued as a calibration index by Isaac Earle in 2022-Feb-08.  After inspection, The inspection tag  was issued and attached to pin. Tom has an inspection record on this job. See attachments.

Tom Gauss inspected  two target module lifting frames ITA0494-1997-01 and ITA0494-1997-02.. He certified the use of these two frames. Inspection tags have been issued and attached to frames. He has inspection record on them. See attachments.

 David did electrical check after target removed from TM4 at NHC. see attachment pls.

 David made an electric check after TM4 been moved to NHC from ITE. The target is still on the module. Please find out attached pic for detail.

 An electric check was done right after module moving from SMP to SHC. 

 The spent UC#36 target in the north hot cell has been removed and placed in the spent target vault. See attached PDF for detail note that the PDF does not show that spot 2B is occupied by the 2A3M20 pail.

TM2( no target ) has been moved  from NHC to SMP.  The moving is smooth and successful.

Frank and I replaced ITW Exit module 1 side square service panel o-ring seal. Also, The target module pit top flange o-ring seal in ITW pit is replaced.
