This is not a propulsion system for space flight. The russians hava claimed to have invented a nuclear ramjet engine. This is a huge difference, because a jet engine still needs air to run. There was a similiar project in the US in the 60ies called Project Pluto. It was abandoned, since it it would have devastated all land within its flightpath, by radiation and its supersonic shockwave. A system like this is only feasible as alternative to ICBMs, in the case of a total nuclear war. A high speed flight system inside the Atmosphere is harder to detect and to defend against.
