Wow. How do they design them to withstand a strike from a 747? That seems really difficult.

- selectodude 6y agoA whole lot of concrete, mostly.
- throwaway0a5e 6y agoThey shot an F4 target drone at a block of "reactor grade" concrete wall back in the 80s and they took measurements and did science on the resulting lack of damage and concluded that a reactor can shrug off one of anything. They didn't change containment buildings to be plane proof. It's just a side effect of the design required to contain a melting down reactor with a sufficient safety factor.

- petre 6y agoYes. A NRC requirement for utility scale reactors after 9/11. One wonders why nuclear reactors are so expensive.
- HPsquared 6y agoIt's a good reason to design reactors to be as small as possible, with a small containment building. Much easier to build.
