I think the dropped fuel accident assumes that the secondary contain=ent remains intact. What if the plane ca=c through the roof into the reactor core or into the spent fuel pool? I don't think the FSAR included this possibility or the possibility of a plane crash at the intake structure.
g Such a crash could possibly cut off all sources of cooling water with the exception of the condensate storage tanks. Of course a fire in the intake tunnel or building ci;;ht possibly result in the dame cutoff.
