The Systems Engineering (SE) Group within the Research Reactors Division (RRD) is seeking a Nuclear Electrical Engineer. The Systems Engineer Group is responsible for the High Flux Isotope Reactor (HFIR) configuration management program. The SE Group also provides technical support to operations and maintenance and performs systems analysis. As an Electrical Engineer you will perform design engineering in support of modifications to reactor systems, provide technical support for electrical maintenance activities, and conduct performance analysis of reactor systems. This role will be assigned responsibility for specific HFIR plant systems.


This position reports to the Electrical/Instrumentation and Controls Systems Engineering Team Lead and interacts with personnel at all levels within the Research Reactors Division.


Major Duties/Responsibilities: 

Configuration Management:

  • Prepares engineering designs for new installations and for replacement and upgrade of reactor structures, systems, and components (SSCs).
  • Performs calculations and interpretations of industry code to support design development.
  • Applies relevant codes and standards, such as DOE Orders, ICC, IEEE (including Nuclear Standards), etc.
  • Task leads field installation and testing of engineering design changes.
  • Provides project management for installation of electrical design changes.
  • Reviews design specifications to define and determine acceptance criteria for material upgrades.
  • Prepares material specifications, initiates, and provides technical support in procurement of nuclear safety-related materials.
  • Implements modifications in accordance with RRD’s nuclear configuration control processes.
  • Prepares and maintains as-built documentation for assigned HFIR SSCs, including engineering drawings, specifications, system descriptions, relevant databases, and labeling.


Maintenance Support:

  • Troubleshoots and analyzes system and component failures and develops corrective actions.
  • Provides written work package directions to perform and document work.
  • Provides field work technical direction to craft supervisors and craft.
  • Develops and implements electrical preventive maintenance work instructions.


Operations Support:

  • Performs operability assessments to determine equipment impact on HFIR operation.

    • Identification of spare parts deficiencies and single point vulnerabilities
    • Walk-downs to assess system configuration and material condition
    • Evaluation of surveillance test results
    • Assessment of open modifications, deviations, and corrective work packages


Basic Qualifications:

  • Bachelor’s degree in engineering or related field and 5 or more years of relevant work experience with electrical emphasis.


Preferred Qualifications:

  • Demonstrated ability to diagnose electrical equipment problems and develop formal work package instructions for performance and documentation of repairs.
  • A strong understanding of reading and interpreting electrical design drawings including single lines and schematics.
  • 10 years of work experience in systems or maintenance engineering.
  • Familiarity with electrical design of power distribution, motor controls, grounding, communication systems, VFDs and relays.
  • Familiarity with the regulatory programs which define the HFIR work environment, including DOE Orders pertaining to conduct of operation and maintenance, OSHA requirements, and IEEE standards would be a plus.
  • Experience in project management, leading maintenance tasks, procedure development, procurement of materials, and equipment analysis.
  • Experience using SKM, ETAP or other power flow distribution software.
  • Working knowledge of the National Electrical Code, NFPA 70E and NFPA 70B.
  • Excellent written and oral communication skills.
  • Motivated self-starter with the ability to work independently and to participate creatively in collaborative teams across the laboratory. 
  • Ability to function well in a fast-paced research environment, set priorities to accomplish multiple tasks within deadlines, and adapt to ever changing needs.
