Experiment Project Engineer

Date: Aug 14, 2026

Location: Oak Ridge, TN, US, 37830

Company: Oak Ridge National Laboratory

Requisition Id 16920 

 

Overview:

We are seeking an Experiment Project Engineer who will perform a diverse set of activities related to analysis, approval, and coordination of in-vessel and gamma irradiations at the Oak Ridge National Lab (ORNL) High Flux Isotope Reactor (HFIR). These will largely include experiments related to materials science and isotope production to support key ORNL objectives. In this role, you will interact and interface with the experiment design and analysis team(s) associated with proposed samples, quality assurance specialists, RRD support personnel, reactor operators, and ORNL transportation-related organizations. If needed in the future, acquisition of certificate for transport of hazardous materials may be required.

 

This position resides in the Experiments and R&D Programs Group in the Nuclear Safety and Experiment Analysis Section of Research Reactors Division, part of the Neutron Sciences Directorate at Oak Ridge National Laboratory.

 

Major Duties/Responsibilities:

Experiment Coordination and Safety Analysis:

  • Work closely with Experiment Task Leaders and Principal Investigators to understand their irradiation needs and guide them in the process of preparing for and carrying out irradiation experiments. This includes providing feasibility evaluations of prospective in-vessel and gamma irradiation experiments with the responsibility and authority to guide experimenters to compliance with HFIR safety requirements.
  • Provide review of experimenter documentation addressing nuclear and experiment safety or programmatic concerns with in-core and gamma irradiation experiments, including evaluation through the Unreviewed Safety Question (USQ) process; ultimately providing final authorization for insertion of experiments into the reactor.
  • Provide consultation for experiment design, engineering, calculation review, fabrication of experiment targets supporting ORNL isotope production program and materials science efforts.
  • Interact frequently with scientists and engineers of various disciplines both inside and outside ORNL.
  • Plan experiment loading configurations and develop instructions for HFIR Operator use to install them.
  • Perform dose estimates to support safe transportation and handling of experiments irradiated in the reactor.

 

Experiment Shipping and Transportation Support (potentially encountered):

  • Support experiment shipping activities. This could include evaluations of post-irradiation activity levels, isotopic content, review of shipping authorization documents, and coordinating cask loading and unloading operations. Learning will be facilitated by requisite training and working closely with experienced HFIR Experiment and Fuel Transportation Subject Matter Expert.

 

Experiment Facilities Support:

  • Work with RRD Experiments and R&D Program staff, RRD Systems Engineering, and other RRD Nuclear Safety staff to evaluate the existing facilities’ performance and develop corrective maintenance solutions for operability issues as well as conceptualize new facilities or improvements to existing facilities that meet experimenter needs.
  • Participate in HFIR experiment facility health monitoring activities and reporting.
  • Work with HFIR Operations to prepare instructions for installing, adjusting, and removing experiments
  • Gain expertise using the EXSITE experiment planning, coordination, and resource platform.

 

Basic Qualifications:

  • A BS degree in mechanical, nuclear, or aerospace or similar engineering field with at least five years of experience in a nuclear environment such as a nuclear power plant, research reactor or other nuclear facility.
  • Fundamental understanding of nuclear physics, materials science, and nuclear processes for isotope production.

 

Preferred Qualifications:

  • A relevant MS degree or PhD
  • Experience with experiments at a research reactor 
  • Current Q or L Clearance 
  • Significant experience with coordinating transportation of irradiated isotope and/or materials experiments on a DOE site 
  • DOT hazardous material transportation certification or willingness to obtain 
  • Ability to review and understand neutronics and/or thermal calculations for acceptance 

 

Special Requirements:

  • This position requires the ability to obtain and maintain a clearance from the Department of Energy. As such, this position is a Workplace Substance Abuse (WSAP) testing designated position. WSAP positions require passing a pre-placement drug test and participation in an ongoing random drug testing program.
