Hello, my mother recently sent me a very mediocre article showing concerns regarding the Westinghouse AP1000 PWR with PCCS. The thrust of the concern seemed to be the possibility that the steel shielding could corrode, or be otherwise compromised by an earthquake, leading to a radioactive release a la the chimney effect. I am not a nuclear engineer, but it didn't seem likely to me, given the proposed construction. I did say that I would ask some people who are nuclear engineers, and I would guess there are a few here. To me, the massive reduction in moving parts, and the explosive locks seem to be enhancing safety. I assume this reactor can be SCRAMed like any other as well. Am I missing something, or is this the usual anti-nuclear hysteria?
