In the first case--why do we think it's safe?--look at the history. Look at the CANDUs that have been built in Canada for the past 30-some years and that are operational. You can look at what's been built in Argentina, in Romania, and even the ones in India. The track record is there. There has never been an incident. They've always been operational and they've always worked safely. Every time they're compared to other technologies, they're in the top performing reactors in the world.
I think the issues that have been brought up are just how comfortable and how safe we should feel as citizens being close to nuclear. It's so well micro-managed, it is so well documented, it is so well exposed that every single thing is known in the industry.
