Overview

A Fleet Maintenance Activity nuclear planner writes technical work documents for intermediate level nuclear repairs. The planner conducts detailed research on technical accuracy, required materials, sketches, radiological containment fabrication, work step flow, and post repair testing.

Core Skills

  • Nuclear repair technical work document development
  • Repair materials research and sketch preparation
  • Radiological containment fabrication planning
  • Repair sequencing and post-repair test planning

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.

Mechanical Engineering Technologists and Technicians

Developing repair sketches, researching materials, and writing work steps and post-repair testing requirements transfer directly to mechanical engineering documentation and test support.

How to prepare: Complete an AutoCAD drafting course and create a non-sensitive sample repair drawing with an accompanying work sequence and test plan.

What the civilian work involves
  • Interpret engineering sketches, specifications, or drawings.
  • Review project instructions and blueprints to ascertain test specifications, procedures, and objectives, and test nature of technical problems such as redesign.
  • Provide technical support to other employees regarding mechanical design, fabrication, testing, or documentation.
Civilian tools and software (examples)
  • Autodesk AutoCAD

Nuclear Technicians

Researching nuclear repair procedures, radiological containment fabrication, and post-repair testing provides a foundation for nuclear equipment safety and testing work.

How to prepare: Seek a nuclear equipment testing course with supervised laboratory practice to build hands-on experience beyond repair planning.

What the civilian work involves
  • Follow nuclear equipment operational policies and procedures that ensure environmental safety.
  • Conduct surveillance testing to determine safety of nuclear equipment.
  • Test plant equipment to ensure it is operating properly.
