The Nuclear Regulatory Commission and EPA, et cetera, had worked out what allowable releases are.

All of the information that we were getting up to that time from the NRC people, from our people who knew something about nuclear power, was that the breach of the core was not a likelihood to happen.

When I started walking and I looked down and I saw on the floor this water, which looked like, you know, water in your basement except it happened to be in the auxiliary building of a nuclear power plant.

Nobody could tell us or really had a very good idea, if there were a massive release of radiation, what kind of medical treatment people were going to need and this or that, or, indeed, whether there would be medical personnel around.

None of us are nuclear experts, but we know that if there is a melt-down and breach of containment, that's clearly the most odious thing that could happen.

Another very strong image from the first day was giving my initial press conference in the morning - going down and finding out that everything I had said, the essence of what I had said, was wrong.
