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

Directing and reviewing shipboard nuclear operations and maintenance provides closely related experience for civilian reactor operations.

How to prepare: Ask a commercial nuclear facility's operator-training program to evaluate your documented Navy qualifications and experience for an operator licensing pathway. NRC licensing requires meeting the facility's education, training, and experience criteria, with facility certification of 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.
  • Respond to system or unit abnormalities, diagnosing the cause, and recommending or taking corrective action.

Nuclear Technicians

Reviewing nuclear operations and maintenance provides relevant experience for monitoring nuclear equipment performance and identifying maintenance needs.

How to prepare: Build a targeted resume mapping your documented nuclear operations and maintenance work to equipment monitoring and testing duties in technician openings.

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.
