In the Soviet Union the first designs to envision the use of nuclear power in submarines date back to the late 1940s. At the time, the Nuclear Energy Institute began to develop a 5,000-kwt reactor for the first Obninsk nuclear electric power plant in the world; it was believed that this uranium-graphite reactor would be suitable for ship propulsion as well. At the same time, Soviet ship designers attempted to determine what the nuclear submarine would look like.
