Postdoctoral Research Associate - Nuclear Forensics Modeling

Date: Jun 6, 2024

Location: Oak Ridge, TN, US, 37830

Company: Oak Ridge National Laboratory

Requisition Id 12852 

Overview:  

As a U.S. Department of Energy (DOE) Office of Science national laboratory, Oak Ridge 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, Nuclear Security Sciences Directorate at ORNL.  

 

Major Duties/Responsibilities: 

  • Develop and implement calculational methods for simulation of detector responses to nuclear weapon fallout and interpreting the nuclear forensic data.
  • Conduct cutting-edge research in the use of aerial detector surveys to provide a nationwide means of predicting yield from a nuclear detonation. The research will also extend our ability to rapidly update our models based on the aerial measurement data. A sensitivity study will be performed to show the relative impact of the different types of flights that are performed by aerial systems in a graded approach (e.g., edge detection versus serpentine versus complete mapping).
  • Develop and maintain the codes used for this evaluation, test their performance on different operating systems, and validate results using both numerically generated and actual measured data.

 

All team members 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:

  • PhD in nuclear engineering or related field, completed within the last five (5) years.
  • Experience solving a variety of real-world modeling problems.
  • Research and development experience in nuclear fuel-cycle processes.

 

Preferred Qualifications:

  • Experience with the SCALE code system and with models of various fuel-cycle processes.
  • Programming experience using FORTRAN, C/C++ and/or other high-level languages.
  • Programming on parallel processors using the message-passing interface (MPI).
  • Knowledge of and experience with numerical analysis and applied mathematics, including optimization, statistics, and solution of inverse problems.
  • Diverse experience in many application areas such as nuclear forensics, neutron and gamma ray detection, and safeguards technologies.
  • Ability to effectively communicate, both verbally and in writing.

 

Special Requirements:

Applicants cannot have received their Ph.D. more than five years prior to the date of application and must complete all degree requirements before starting their appointment.
