The OK-550 reactor is a type of nuclear reactor developed in the former Soviet Union, specifically designed for use in naval applications. It is a pressurized water reactor (PWR) that was primarily intended for propulsion in submarines and other naval vessels. The OK-550 reactor is a more advanced version compared to its predecessors and is known for its compact design, high power output, and efficiency in converting nuclear energy into mechanical energy for propulsion.
