Stage 1 polishing (water scale and at least 99% of visual indium removed) has been achieved on all 2 seal water blocks that will be used (Ground electrode has not been polished). Process required 3-4 3minute cycles of the tool using scotch brite pads with the tool running at approximately 75 psi.

Stage 1 polish has been achieved on all single seal water blocks using the single pad tool run at 75 psi, 2 3 minute cycles per block using red scotch brite.

Phase 2 (intermediate) and Phase 3 (Final) polishing is complete on all water blocks on TM2 (minus ground electrode circuit which has only had a cursory cleaning). Phase 2 with 2000 grit wet sand paper and isopropynol for 1 minute with tool at 75 psi, Phase 3 with Veltex polishing cloth for 1 minute with tool at 75 psi.

 TM#2 has been moved from the conditioning station to the south hot cell.

This morning new water block fasteners and gas line capture nut fasteners were inserted into the hot cell. Window waterline blank off was removed from TM2, surfaces inspected and given a polish with Veltex (30 seconds, 70 psi) as there was a small bit of c seal residue. Transfer try with new source tray has been latched to the module.

Monday, March 25, 2019, 10:00: Target electrical checks (See Attachment 1)

Tested for TM2 

 The four electrical check done on TM#2 during the source tray change.

Pail transfer was undertaken in the south hot cell. went very well except near the end the master tong cable of the right hand manipulator broke. Not entirely a surprise due to the amount of use it has seen lately.

Broken handle cable of east manipulator has been replaced and manipulator is operational again.

 Targets Ta#50 and SiC#34 have been transferred from their old pails to new ones. Ta#50 was done on April 12th 2019 it was moved from pail #148 to pail #200 and a new field measurement was done and found to be 3.57mSv/hr. SiC#34 was done on April 18th 2019 it was moved from pail #143 to pail # 206 and a new field measurement was done and found to be 2.20mSv/hr. Both measurements were done by the RAM that is mounted at the south hot cell.

April 24 2019

Target Ta#46 has now been transferred to a new pail with a number 207 from pail 143 it was 3.62 mSv/hr when removed from the south hot cell.

April 25 2019

Target Ta#47 has now been transferred to a new pail with a number 201 from pail 137 it was 2.25mSv/hr when removed from the south hot cell. The bag that the target was in has shown signs of degradation.

Target Ta#45 has now been transferred to a new pail with a number 202 from pail 124 it was 1.45mSv/hr when removed from the south hot cell. The bag that the target was in was destroyed. Also in the pail was a shutter, IMG Gauge, some altem parts, wire and bolts.

The extraction electrode from Ta#47 was added to this pail as it was left behind from last transfer.

Two pail transfers took place April 25th.

Ta#47 transfered from pail 137 to pail 201. existing plastic bag from 137 showed many areas of typical age/rad damage related failure.

Ta#45 in pail 124 was transfered to pail 202. Pail 124 also contained the shutter and "roof mounted" img gauge from TM2 that were removed in 2015 in addition to a bunch of fasteners, heat shrink tubing (from lock lever rings from an previous methods of spent target packaging) etc. The original plastic bag in pail 124 had completely failed and shredded and flaky. The shutter and extraction electrode from Ta#47 were put in pail 202 with Ta#45...cabling of the shutter being completely intertwined with the target.

 TM#4 with UC#26 has been moved from ITE to the south hot cell.

 Electrical check of TM#4 with UC#26 post beam at the south hot cell. See attached.

UC#26 has been removed from TM4.

 TM#4 has now been moved to the south west silo.

 Electrical check of the TM#4 with no target attached at the south hot cell before being moved to the south west silo.

 The entrance module has been moved from the west station to the south hot cell.

West entrance module - visible broken or disconnected wire visible on old/existing wire scanner. Wire scanner removed, new one installed.

Ta #58 has been installed onto TM2. All new silver plated high current fasteners. All torqued to 130 in lbs.

 Results of the electrical check of TM#2 without target and with the new Ta#58 target.
