So, are you saying the big secondary containment structure—that mass of concrete and steel—is essentially gone?

Looks like some of the steel frame is still intact. The concrete was annihilated in the explosion. Only hydrogen could do that. A freeper posted minutes before the explosion report that Boiling Water Reactors BWR can theoretically experience a hydrogen explosion. This was when the Sky is Not Falling crowd was pointing out that an explosion was impossible. Unfortunately for us apparently anything is possible on planet ape.
