The S5G nuclear propulsion plant, installed only on the SSN-671 Narwhal, was a natural-circulation reactor intended to test the potential contribution of this technology to submarine quieting.

As a prototype reactor for USS Narwhal (SSN 671), the S5G was capable of operating in forced or natural circulation flow modes. [1] Natural circulation enabled water to flow through the reactor plant without the use of pumps, thus reducing noise levels substantially.
