Why do you speak on topics you obviously know so little about? Where did you get this nonsense?

Fast neutron designs aren't without their challenges, but causing an atomic explosion is not on that list. Hydrogen explosions? Possible. Steam explosions? Possible.

Atomic explosions? Not even theoretically can you get enough U-235 to clump together to do that without cancelling known basic laws of physics.

To build a bomb, you need a purity of 90%+ U-235. Nuclear power plants have what? 2%? 3%? Might even go as high as 5%? Might as well expect a pack of bubble gum to spontaneously explode.
