In 1963 Korolev's OKB proposed development of a massive nuclear-powered geosynchronous satellite, which would be launched by the N1 superbooster. The spacecraft, 25 m long, would have the form of a long cone followed by cylindrical sections. The cone would be the nuclear reactor; the conical section contained the communications equipment, on-board control systems, and cylindrical heat radiators for the reactor.
The orientation system would point the satellite to within 0.5 to 1 degrees accuracy. Three such satellites would provide global coverage. Average operating life was expected to be two to three years. In support of this project research was undertaken on a fast-neutron reactor with beryllium reflectors and a niobium case. Coolant cycle would use liquid lithium Li - Li-7. Thermal output of the reactor would be 6,000 kW and net average electrical output 600 kW. The reactor core had a diameter of 0.75 m, a length of 1.1 m, and a mass of 1,000 kg. The draft project of 1963 foresaw completion of system design in 1965 and flights from 1967. Although work continued throughout the 1960�s on development of the reactor, the communications satellite itself was not approved.
