Back to the present, or there abouts, with this SPACENEWS article from last year that may be of some interest: http://spacenews.com/41399europa-clipper-would-wash-out-other-nuclear-powered-missions/
Wow, that is just sad. I had no idea our capability there had deteriorated so far.

That photo by Carmelo- Is that William Lundigan, AKA "Colonel McCauley" from "Men into Space"?

DUMBO was a competing design to NERVA
sadly there there only budget for one Concept, so they take NERVA and dump the other

DUMBO have a far superior mass flow as NERVA, therefor a far superior thrust, But needed a Nozzle with much active cooling needs as NERVA.
here PDF about DUMBO

So NERVA was chosen because of it's simplicity?

Nuclear space ship possible now

SEATTLE (AP) — A reactor-powered space ship which could keep going for a year at cosmic speed can be built now, a space scientists asserted Wednesday.
The device would consist of a nuclear reactor about the size of an oil drum, a passenger cabin and a piece of coaxial cable a mile long. In space the reactor would be at one end of the cable and the cabin at the other.
In this setup the reactor would supply electrical current which would travel along the cable to the rear end of the cabin. There the current would convert atoms of cesium, a rare metal, into charged particles and cause them to act like hot gases coming out of a jet.
The jet would be located at the rear end of the cabin, where the cable from the reactor would be attached. The cable would keep the reactor far enough away from the cabin to prevent exposure of the passengers to radiation. It also would tow the reactor.
A proposal for such a reactor was put before the American Institute of Electrical Engineers Wednesday in a paper prepared by Dr. Gail B. Shook. Dr. Shook is a physicist at the Lockheed Missiles and Space Laboratory, Palo Alto, Calif.
A feature of the reactor would be the direct conversion of its heat into electrical current by tiny battery-like things called thermionic cells. Heat from the reactor would cause electrons to boil off an inner surface of the barrel. The cells, on another inner surface, would collect the electrons and move them down the cable in the form of a 100-volt current.
At the rear end of the passenger cabin the current would heat powdered cesium into vapor. It also would heat a metallic grid which would give the vaporized cesium an electrical charge, causing them to shoot out the jet exhaust as speeding ions.
The big problem, Dr. Shook said would be to get the assembly into gravity free space. He suggested this might be done with two large rocket engines — one for the reactor and one for the cabin. They would be fired simultaneously, lifting reactor, cable and cabin — all assembled into a working unit into space.
The ions in the ship's jet, Dr. Shook said, would produce only a feeble amount of thrust, about a thousandth of the force of gravity. But this would be enough to move the ship through airless, gravity free space at high speed.

(Ellensburg Daily Record. - 1959. - June 24. - p. 1).

Vehicle Would Use Ion Propulsion in Space

Lockheed Missiles and Space Division has proposed a space vehicle (left) to be propelled by a low-thrust ion rocket after vehicle and nuclear reactor are boosted into space by a chemical rocket. Spacecraft would be separated from reactor by a mile-long coaxial cable for radiation protection. Reactor is at 2,100C and "boils” electrons off thermionic cells (right) placed around outer shell of reactor, thereby directly producing electrical energy which is transmitted through cable to power ionic propulsion system. Total power yield of 34-ton unit would be 1,000 kw.

(Aviation Week Including Space Technology. - 1959. - Aug 3. - p. 63).

Scientists at the Lockheed Missiles and Space Division have proposed a relatively simple "cocoon" system for a manned flight to Mars. The new design — seen here in an artist’s impression—differs from other proposed Mars systems by using two huge chemical booster-rockets (top left and bottom right) as part of the Mars ship itself. In the impression the glowing, trailing object (bottom left) is a nuclear reactor to provide power for air supplies and other important life-support systems. Inside the cut-away section of the nearest chemical rocket-booster (top left) can be seen a return-to-Earth vehicle, with, at the other end of the cable (bottom right) a chemical rocket-booster containing equipment for a Martian landing.
