|
TM2 is in the TCS without containment box for HV testing following the installation of the IGLIS wiring.
Not great results so far - sat at 42.5kV for nearly 2 hours, current around 200uA and occasional sparks. I did not have time to go higher, will
do this tomorrow. The sparks could be conditioning but it looks a bit suspicious to me. We will see if the ramp up tomorrow is very easy and how high we |

5 pails were moved from the mini-storage vault into F-308's
At one point during the loading the mini-storage vault door would not close. Cause was a blown fuse, which was replaced and operations were able
to continue as usual. Possible reason the fuse blow was a tilted pail that may have become jammed between the tray and the roof of the mini-storage vault. |

Dan lubricated components on the target storage vault (This was an outstand task from annual inspection). No issues on the main storage vault but we
were not able to lubricate the mini storage vault because the position of the grease nipple on the fittings makes them inaccessible, see attached pictures.
All four should be replaced with 90 deg fittings. |

ITE:ANODE supply reading strange currents - 17mA with the power supply on and no voltage. Checked anode circuit from electrical room:
Anode wire in electrical room shows 0L at 250V
Circuit with 50kOhm resistor mostly looks good (49-52kOhms) but a couple times read 28kOhms, no idea why. Tried jiggling all cables, unplugging |
