Inspectors this fall focused on Westinghouse's crash analysis. Their report identified several concerns, including what inspectors deemed a failure to adaquately consider the effects of an airline strike that hits an annex building, penetrates another structure and heads toward an equipment hatch.
When I was with the old company we were constantly plagued by the Nuclear Safety Department thinking up some new whacko accident scenario. No probability was too small!
So now it's the airplane thing. It's not enough to think of a general hit, it has to thread it's way through buildings and into a fully open equipment hatch! (which are hardly ever open). And do we think we'll have new nuclear soon?
