Nuclear Spacecraft Textbook

My master's thesis dealt with mission analysis for nuclear rocket propulsion systems.  It was intended as an introduction the principles and physics involved, both for mission planners and for students.  Now my goal is to finish the necessary modifications and rewrites to create an introductory textbook on the subject of nuclear spacecraft propulsion. 
 This book will explain, as simply yet completely as possible, the physics of nuclear propulsion systems.  It will allow those with a background in rocket propulsion to understand the nuclear mechanics issues as easily as it allows those with a background in nuclear reactors to understand the propulsion issues.
