Can a Reusable Nuclear Pulse Propelled Craft Be Made?

[+energy]

Hello, my name is Alexander Radchik and I have always wanted to be an atomic play boy.
Given the lack of easily obtainable fissile material I have had humble myself to the theoretical use bombs for things that make sense. Regarding my query, I have 2 questions.
1) could a reusable nuclear pulse propelled craft be made, why, why not?
2) explain what you think would be the maximum sustained fall out
Thank you
Alexander

One is describing a system similar to Project Orion - http://en.wikipedia.org/wiki/Project_Orion_(nuclear_propulsion)

Fallout would depend on yield. The concept is not take seriously, and the deployment of nuclear weapons in space is effectively banned.
