The dream of Sergei Korolev, Wernher von Braun and their predecessors to design a powerful engine for long-term space flight missions may soon come true. Roscosmos Head Vladimir Popovkin has announced that the engineering prototype of a megawatt-class nuclear propulsion unit for outer space missions will be developed in Russia in 2017.
Bench tests of a reactor for a nuclear-powered spacecraft may start in Sosnovy Bor near St Petersburg as early as next year. In June 2010, then-President Dmitry Medvedev issued an instruction backing the project of a space transport and power module based on a megawatt-class nuclear power installation.
The president promised 17 billion roubles to implement the project in 2010–2018, 7.245 billion roubles of which were earmarked for Rosatom to build the reactor. The M. V. Keldysh Research Centre will receive 3.955 billion roubles to create the nuclear propulsion unit, and the remaining 5.8 billion roubles will be used to finance the design of the transport and power module by the Rocket and Space Corporation (RKK) Energia.
A closed cycle turbine system using "hot gas"? How does "hot gas" spin a turbine? There's a reason steam is used in generators instead of "hot gas".
The hot gas from the reactor spins the turbine and the turbine spins the generator and the compressor, which provides the closed circuit circulation of the propellant.
The generator produces electricity for the plasma engine with a specific thrust 20 times higher than that in a chemical engine.

You know .. in Stargate:SG-1, it is the russians that create earths first mothership : Prometheus, Or am i wrong? Its been awhile.

I wonder how much air they will be able to carry on the type of ship that this would power.
And maybe we should be proud of the achievements of our fellow humans instead.
