Detailed explanation-1: -F-1 was the first nuclear reactor in the USSR and in Europe. In 1949, the USSR conducted its first successful nuclear weapon test, followed by the test of the first Soviet thermonuclear bomb in 1953. In 1958, the first Soviet nuclear submarine, Leninsky Komsomol, was built.

Detailed explanation-2: -The Soviet nuclear programme is based on two types of thermal power reactor: the WWER pressurized light- water-moderated and cooled reactor; and the RBMK light-water-cooled, graphite-moderated, channel-type reactor. The first nuclear power projects were started in the Soviet Union even before the end of the 1940s.

Detailed explanation-3: -The Soviet atomic bomb project was the classified research and development program that was authorized by Joseph Stalin in the Soviet Union to develop nuclear weapons during and after World War II.
