Nuclear Data Analyst- R&D Associate

Date: Jun 11, 2021

Location: Oak Ridge, TN, US, 37830

Company: Oak Ridge National Laboratory

Requisition Id 6003 


The Nuclear Data (ND) Group within the Nuclear Criticality, Radiation Transport and Safety Section of the Nuclear Energy and Fuel Cycle Division (NEFCD), Fusion and Fission Energy and Science Directorate at Oak Ridge National Laboratory (ORNL), seeks applicants for a nuclear physicist, with an emphasis in the area of nuclear data research to support nuclear technology applications. The primary function of this open position is to develop novel nuclear data analyses methods to be implemented in ORNL nuclear data evaluation and processing software code packages such as SAMMY and AMPX.


Major Duties/Responsibilities: 

 The nuclear data analyst staff member will perform methods development in cross section evaluation, processing and testing, and radiation transport analyses to support nuclear technology applications. The successful candidate will be involved in performing research and development in (1), advanced cross section evaluation and processing methods, (2) analysis and evaluation of thermal neutron scattering data, (3) development of new and/or enhancement of existing computational capabilities to support the modernization of the AMPX, SAMMY, and SCALE code packages,  (4) generation and testing of nuclear data sets using cross section processing systems (i.e., AMPX and NJOY) and radiation transport packages (i.e., SCALE and MCNP) and (4) development of covariance data
The selected candidate will be responsible for interacting with division staff members inside and outside the ND Group, working on projects in a team environment, working independently, and leading R&D activities. The successful candidate is expected to be able to interface effectively with project sponsors, participate in the development of research proposals, and publish results of their work


Qualifications Required:

The successful candidate must have a PhD degree in physics or nuclear engineering and demonstrated accomplishments nuclear data evaluation and/or analytical methods development for nuclear data applications. Programming experience in modern FORTRAN and/or C++, is desired, as well as a firm understanding of the physics and methods of cross section processing, nuclear data analysis, and radiation transport analysis backed by demonstrated recent and relevant experience with current analysis codes, such as AMPX, NJOY, SAMMY, SCALE and MCNP. Demonstrated problem-solving skills, a willingness to apply those skills to a variety of problems, and the ability to determine and understand the broader context of his or her research are also requirements for this position.


Experience in nuclear data theory development, experimental data evaluation and covariance development for elastic scattering on materials as a function of temperature is highly desirable.


Excellent communication skills, including verbal, presentation, and writing skills, are required to enable effective interaction with technical peers, program managers, and sponsors. Candidates must also have a successful publication record.
