We all know the reactor is melting down to some point since they admitted it. My questions is, how do you stop it once it's started? I don't believe you can although I'm not an "expert" that's for sure. But if the concrete has been burnt through and no one can go near the place, then you can't seal it. All you can do is dump water on it forever, so it doesn't get worse. Like that's going to happen too.
And no one can go in there to see if the reactor is still contained, so how do they know? I've listened to a few of the "experts" explaining all this and it doesn't make since! It reminds me of a cop or judge explaining how you're guilty, when it's all just smoke and mirrors.
