CHUCK CASTO [Deputy Regional Administrator]: [...] if we end up with a molten core and then you talk about the time for the concrete to disassociate, you know, that NUREG says it’s a couple of inches an hour, you know. And, of course, that Mark 1 containment is the worst one of all the containments we have, and it’s literally, you know, this NUREG tells you that in a station blackout you’re going to lose containment. There’s no doubt about it.
But, anyhow, I just would highlight that that is a valuable resource, that NUREG. I think it’s — is it 6150, CR-6150, Perspectives on Nuclear Safety? It completely walks all of this down. It’s already been thought out. It’s already been reviewed, looked at, modeled, everything. So, the one thing the NUREG doesn’t really do is tell you how to stop it, how to mitigate it, other than keeping water on it. But the Lab may have some recommendations.
