The idea of nuclear rockets has quite a bit of merit. Many of the original creators of the atom bomb went on to participate in "Project Orion", an Air Force endeavor to harness nuclear energy for propulsion. "Orion" ran into snags due to nonproliferation treaties and eventually got scrapped in the late 1960's, but progress has slowly been made on rockets that use nuclear reactions both directly and indirectly for acceleration. Very cool stuff.

NERVA was way cool (and it worked too)
