The OK-650 is a type of nuclear reactor developed in the former Soviet Union, primarily used for marine propulsion, particularly in nuclear submarines and icebreakers. It is a pressurized water reactor (PWR) design characterized by its compact size and high power density, which makes it suitable for naval applications where space and weight are critical factors.
