N23S Surface Ship Nuclear Propulsion Plant Supervisor: Reactor Control

Current service use not established

This code is listed in the directory. Inclusion alone does not confirm current service use.

A Navy Enlisted Classification: a skill designation sailors hold in addition to their rating.

Overview

A surface ship nuclear propulsion plant reactor control supervisor leads control room operations and manages reactor power. This supervisor enforces procedural compliance and directs safe responses to abnormal plant conditions.

Core Skills

  • Nuclear propulsion plant maintenance supervision

Civilian Career Paths

Career associations are editorial assessments of the cited evidence, not an official crosswalk unless the evidence explicitly says so. O*NET supplies civilian occupation information, not proof of a military match. Related experience does not confer civilian qualifications. Tasks and tools below describe civilian work, not military training.

Nuclear Power Reactor Operators

Qualified supervision of surface ship nuclear propulsion plant operations provides directly relevant experience for civilian reactor operations.

How to prepare: Ask a commercial nuclear facility's operator training program to evaluate your documented Navy watchstation qualifications and operating experience for its RO or SRO licensing pathway. NRC licensing requires meeting the facility's education and experience criteria and facility certification of required training and experience; the license is valid only for that facility.

What the civilian work involves
  • Operate nuclear power reactors in accordance with policies and procedures to protect workers from radiation and to ensure environmental safety.
  • Develop or implement actions such as lockouts, tagouts, or clearances to allow equipment to be safely repaired.
  • Monitor all systems for normal running conditions, performing activities such as checking gauges to assess output or the effects of generator loading on other equipment.

Nuclear Technicians

Supervising nuclear propulsion plant operation and maintenance provides relevant plant experience for nuclear equipment monitoring and testing work.

How to prepare: Compare your documented plant maintenance experience with nuclear technician openings focused on equipment performance, and identify gaps in their surveillance-testing procedures.

What the civilian work involves
  • Follow nuclear equipment operational policies and procedures that ensure environmental safety.
  • Monitor nuclear reactor equipment performance to identify operational inefficiencies, hazards, or needs for maintenance or repair.
  • Test plant equipment to ensure it is operating properly.
