Chernobyl was designed so that you could open the reactor while it was operating, this is essential for harvesting plutonium for H bombs.
Our power plants are just that - power plants. They don’t have the inherent risks that a bomb factory like Chernobyl had.
American nuke plants have huge containment domes over them. A big plane can crash into them without damage. The domes have contained hydrogen explosions and contain radioactive leakage. Kennedy is of course a family liar.
