|
This morning Don Jackson commented to Grant Minor that he believed the tank lid was still not raised high enough to safely operate the Remote Handling
bridge and trolleys, despite it having been raised 0.5" yesterday to the point of engaging the limit switches (see e-log from yesterday). Don
said he believed this to be the case as a result of a visual inspection with binoculars from the outside of the tank, as well as from the views achievable |
