Journalists -and scientists for that matter - don't usually have access to highly enriched fissile material. Nobody would get permission to do this without a very, very good reason.
Sure, and maybe there's a way to approximate it? I don't know. I'm not particularly well versed on this topic, but when I hear "reconstruction of Foo" I imagine, well, a reconstruction of it. Not an artists visual interpretation of it. This is the first time I've ever seen a recreation in a purely visual sense.
