Teresa,
Definately not fan. The fire marks are coming from the front of the thrust reverser cowl (Hot section). By the photos it is definately an uncontained turbine disc failure. And yes the engine design is supposed to contain this type of failure.
Does anybody remember the Air New Zealand 767 that blew a CF6-80A on climb out of Brisbane (I think 2002). That was a very similar event (uncontained failure) and they were very lucky that all the debris went outboard and thus did not enter the passenger cabin.
If I recall correctly that engine was purchased by Aviation Australia once the investigation was finished.
