Requisition Id 11701 

Overview: 

As a U.S. Department of Energy (DOE) Office of Science national laboratory, ORNL has an extraordinary 80-year history of solving the nation’s biggest problems. We have a dedicated and creative staff of over 6,000 people! Our vision for diversity, equity, inclusion, and accessibility (DEIA) is to cultivate an environment and practices that foster diversity in ideas and in the people across the organization, as well as to ensure ORNL is recognized as a workplace of choice. These elements are critical for enabling the execution of ORNL’s broader mission to accelerate scientific discoveries and their translation into energy, environment, and security solutions for the nation.

We are seeking a Postdoctoral Research Associate who will support the Incident Modeling and Computational Sciences Group in the Nuclear Nonproliferation Division, National Security Sciences Directorate at Oak Ridge National Laboratory (ORNL).  

Major Duties/Responsibilities: 

• The responsibilities of this position include conceptualizing and performing research and development in the
• assessment of proliferation in every stage of the nuclear fuel cycle and nuclear weapon production.
• Expertise is expected in one or more of the following areas: uranium enrichment, reactor production of plutonium, depletion and activation processes, fuel reprocessing, and forensic evaluations of nuclear materials.
• The primary focus for this position is to develop and implement calculational methods for simulation of these nuclear fuel-cycle processes and interpreting forensic data.
• The research will focus on developing and validating mathematical methods, incorporating inverse calculations and statistical models, and integrating these methods into existing modeling and simulation (M&S) tools.
• The researcher will maintain and develop the codes used for this evaluation, test their performance on different operating systems, and validate results using both numerically generated and actual measured data.
• Work will usually include a statistical analysis of the uncertainties and correlations in the reconstructed values.
• The researcher will maintain a strong understanding of the overall goals of various federal agencies involved in nonproliferation nuclear forensics missions.
• The selected candidate will be responsible for interacting with division staff, both within and outside the Nuclear
• Security Modeling group, who work on projects in a team environment.
• The candidate will be expected to work independently, perform R&D activities, fully document work in technical reports and publications, effectively interface with project sponsors, and participate in the identification and development of research proposals.
• Deliver ORNL’s mission by aligning behaviors, priorities, and interactions with our core values of Impact, Integrity, Teamwork, Safety, and Service. Promote diversity, equity, inclusion, and accessibility by fostering a respectful workplace – in how we treat one another, work together, and measure success.

Basic Qualifications:

• A PhD in nuclear engineering, or a related field completed within the last 5 years
• Recent experience in nuclear fuel cycle analysis and nuclear forensics, with demonstrated accomplishments in the solution of a variety of real-world problems.
• A firm understanding of the physics and chemistry of nuclear fuel-cycle processes, backed by demonstrated recent and relevant research and development in the field, is a fundamental requirement.
• Excellent verbal, presentation and writing skills are required to enable effective interaction and communication with technical peers, program managers, and sponsors.

Preferred Qualifications:

• It is highly desirable for the candidate to have experience with the SCALE code system and with models of various fuel-cycle processes.
• The candidate should have considerable programming experience using FORTRAN and/or other high-level languages.
• Additional capabilities, such as programming on parallel processors using the message-passing interface (MPI) are a plus.
• It is highly desirable for the candidate to have knowledge and experience with numerical analysis and applied mathematics, including optimization, statistics, and solution of inverse problems.
• The ideal candidate would also have diverse experience in many application areas such as nuclear forensics, neutron and gamma ray detection, and safeguards technologies.
