How much uranium-235 would be consumed in a fission bomb with a 20-kt explosive yield?

1. How much uranium-235 would be consumed in a fission bomb with a 20-kt explosive yield?
2. A neutron collides elastically head-on with a stationary deuteron in a reactor moderated by heavy water. How much of its kinetic energy is transferred to the deuteron?
3. A buildup of fission products “poisons” a reactor, dropping the multiplication factor to 0.995. How long will it take the reactor power to decrease by half, given a generation time of 0.15 s?
