As a nuclear safety engineer, you will work to fulfill an important regulatory function in a dynamic environment. Our nuclear safety engineers are responsible for obtaining federal authorization to conduct nuclear operations at the Y-12 National Security Complex (Y-12). These operations, which support the manufacture of nuclear weapon components and naval reactor fuel stock, involve a wide range of activities including chemical processing, metal production, casting, machining, assembly and disassembly, transportation, and storage.
Nuclear safety engineers are responsible for evaluating accidents that could occur during operations (events ranging from process upsets and equipment failures to fires, earthquakes, and floods). Nuclear safety engineers also are responsible for identifying the safety measures that need to be implemented to ensure the workers and public are adequately protected. Those measures range from administrative controls, such as material inventory limits, to engineered controls, such as fire suppression systems. To fulfill those responsibilities, nuclear safety engineers must develop a working knowledge of Y-12 operations and federal nuclear safety requirements and work closely with subject matter experts representing Operations, Engineering, and numerous other Y-12 organizations.
Nuclear safety engineers routinely perform the following tasks:
- Conduct hazard evaluation studies and accident analyses
- Identify safety controls that ensure adequate protection of workers and the public
- Perform Unreviewed Safety Question Determinations to determine if federal approval is needed before making changes to operating procedures or facility equipment
- Evaluate operational events and new technical information to identify potential nuclear safety issues
- Maintain safety basis documentation for nuclear operations via development of document change notices and annual updates
- Support projects to design, install, and start up new capabilities and technologies
- Develop major modification determinations to identify requirements when making substantial changes to nuclear operations or nuclear facilities
- Brief federal counterparts on the safety posture of nuclear operations at Y-12 to include both the scope of hazards analyzed and the safety controls identified
