Engine Model: RD-600. Manufacturer Name: RD-600. Designer: Glushko. Developed in: 1962-70. Application: interplanetary launchers stage 2. Propellants: Nuclear/LH2. Thrust(vac): 1,960.000 kN (440,620 lbf). Isp: 2,000 sec. Chambers: 1. Country: Russia. Status: Developed 1962-70. Gas core nuclear engine worked on by Glushko 1962-1970. For use in second stage of two-stage interplanetary rockets. This gas phase nuclear reactor was designed by Energomash for a Venus station/Mars flight. It would be launched from orbit. Work stopped in the USSR (and in the US) but it would have worked well in principle. This was one of the 'B' category engines developed by OKB-456 Filial 1 because it was too dangerous to test at Khimki.
