Of course there will always be a better and safer design. But what about replacing the 50 year old designs currently deployed now with recent ones?

Can we afford to do that?

We have finite resources. If prevention of a disastrous change in climate is your goal does it make sense to replace the older plants?

Yes it would be safer to do so but would the cost be worth it?

They angry mob will refuse to let you build the replacement, and demand the old one be torn down since you admitted it's so unsafe.
