Given when Brown's Ferry was built (construction started in 1966), plus just how many million American engineers, construction workers, and service members had hard-won WWII-era experience with "if you do it that way, then it may burn up / sink / explode with just one hit" design principals - one has to wonder at the management of the Brown's Ferry design process. How did they manage to keep all of the real grown-ups out of the room?
