Which officer oversees the nuclear technicians on board a submarine?

The responsibility of overseeing nuclear technicians on board a submarine primarily falls under the Reactor Controls Assistant. This role is specifically designed to manage personnel focused on maintaining and operating the nuclear reactor and its associated systems. The Reactor Controls Assistant ensures safety standards are met and that the technician crew is adequately trained and compliant with operational procedures. This position is critical in maintaining the performance and safety of the submarine’s nuclear propulsion system.

While the Engineer Officer manages the overall engineering department and the Division Officer may oversee various personnel, including those in specialized roles, it is the Reactor Controls Assistant who has the specific task of closely supervising those working directly with reactor controls and nuclear systems, making it the most appropriate choice in this context.
