On November 10th / 11th a site wide power outage occured. Once power was restored, the Ar glove box had intermittent issues with the solenoids & blower. The blower did not start & the solenoids often got stuck or ceased operating. 

Yesterday Randy B inspected the connections to see if they were receiving enough power. It was good from the main plug-in, through to the PLC, however was dead at fuse positions 3 & 4 on the rear panel. Both fuses were changed, but that did not help. We did some fidgeting in the back & the solenoid function returned. It was left overnight.

Thursday, November 30, 2023, 08:30: <- Approx. Initial check: Dropped a crumpled Kimwipe inside the glove box to check for air flow / blower function. It did not move. Blower was not functioning, but the solenoids did. De-energized the glove box completely. 

Removed the old corroded fuse holders, added a pair of modified new ones. Cleaned a couple of corroded critical connections. Installed the new fuses, re-plugged it back in. Function returned to normal. The Kimwipe was also moving, verifying the blower is again operational.

 Thursday, November 21, 2024, 11:46: 2 Glovebox gloves were changed. The far right glove & the far left glove. 

No contamination was found on the sealing edges of the glove box. Both old gloves were placed in bags & placed in the alpha waste bin.

Work Permit: I2024-11-21-2

Note* Changing both inner gloves is recommended later. We had considered to do both however the O2 ppm spiked after the change of the first two. We were at 185 ppm & aim to not cross 200 ppm.

Additional info:

The remaining gloves were inspected and appeared in acceptable condition.  A regeneration was performed shortly after and the gas lines, pump lines were also inspected.  This will be considered as the inspection for the current inspection cycle.
