Radiation Transport- Senior R&D Staff Member

Date: May 27, 2021

Location: Oak Ridge, TN, US, 37830

Company: Oak Ridge National Laboratory

Requisition Id 5207 



Oak Ridge National Laboratory (ORNL) is seeking candidates for a senior/distinguished scientist position in the Radiation Transport group to expand research and development (R&D) focused around nuclear analysis, design and integration for fusion systems.

This position will reside within the Nuclear Energy and Fuel Cycle Division in the Fusion and Fission Energy and Science Directorate at ORNL.  ORNL has world-leading expertise in the fusion energy field including being the headquarters of U.S. ITER and the site of the MPEX project.  ORNL also has world class super-computing capabilities in Summit and Frontier that can be leveraged for fusion radiation transport analyses. The ORNL Radiation Transport group develops, applies and deploys state of the art modeling and simulation capabilities, along with leveraging extensive experience, to solve challenging radiation transport and shielding problems across a wide range of nuclear applications areas. Our methods and codes are deployed through the Exnihilo massively parallel radiation transport code suite (including the Shift Monte Carlo code and the Denovo deterministic transport code), through the SCALE and VERA code suites, as well as through the ADVANTG tool suite, in collaboration with industry, national laboratories, and universities. This position will help coordinate and leverage current fusion and fission radiation transport analysis, design and integration expertise at ORNL to solve challenging problems in collaboration with the U.S. and international fusion communities. 

A successful candidate will be expected to forge ties within ORNL and with national and international fusion community entities and industry partners.  They will create an integrated team of analysts to truly transform the nuclear analysis, design and integration of fusion systems.  Collaboration and partnering with internal and external collaborators will be key to maintaining existing and establishing new ventures and research opportunities in nuclear analysis, design and integration of current and future fusion systems for the national and international energy future.


Major Duties / Responsibilities:


  • Provide scientific leadership in the development of world-leading nuclear analysis, design and integration for fusion systems by forming collaborative, cross disciplinary teams internal and external to ORNL, develop strong research proposals, and conduct world-class research publishable in peer-reviewed journals
  • Engage with the fusion industry to advance and support R&D in nuclear analysis, design, integration and production of advanced fusion energy systems
  • Initiate and conduct research supporting the industrial application of fusion energy and serve as a critical strategic interface between the fission and fusion energy spheres
  • Formulate and implement ideas and impactful approaches to foster the growth of the ongoing fusion systems and fusion nuclear analysis, design and integration R&D within ORNL and the national laboratory system
  • Interact effectively across organization structures with staff at all levels and be an effective and engaged representative of ORNL and its research to sponsors and the professional community
  • Serve as a role model for the integrity and safety of conducting research, mentor early career staff, and engage with scientific and professional societies




  • This position requires a PhD in one of the following disciplines: nuclear engineering, mechanical engineering, physics, radiological science, or applied math
  • Candidates must have over ten years of experience in the areas of nuclear analysis, design and integration, with fusion system neutronic analysis preferred
  • This position requires experience in applying advanced computational radiation transport and shielding analysis and design methods and code suites, and performing complex neutronics analyses for nuclear systems and one or more complementary technical areas such as fission and/or fusion systems; isotope production; material activation, transmutation and depletion; nuclear data and physics; multiphysics; etc.
  • Candidates must be recognized leaders in their fields with a strong publication record, problem-solving skills, extensive proposal writing skills, and a proven track record in program development and team building
  • Candidates must have excellent verbal and written communication skills and be comfortable interacting with peers, with program managers, and with national and international sponsors
