Cleaned top of the ITE vacuum flange and top of window clamp. Attempted to clean the bellows/beam pipe through the wall, mostly dust and small particles.
When cleaning bottom of the wall penetration we picked up a stone/fragment and the vacuum stopped. Appears to be a rock of some kind. 800cpm.

Continued with vacuuming inside wall penetration to remove debris. Changed filter bag in nilfisk vacuum, left old filter in place however vacuum continues
to stall after >5min use. Vacuum gets quite warm before self shutting off. Debris seems to be falling back down on to joint if vacuum is turned off.
Took some screenshots of video showing removed debris and rust(?) on beam pipe. Video located on remote handling group folder. |
