Neutronics Analyst

Requisition Id 13153 

Overview:    

The Neutronics Group within the Neutron Technologies Division at Oak Ridge National Laboratory (ORNL) is looking for a neutronics analyst, who can contribute to our mission of operating and further developing the Spallation Neutron Source (SNS) and the High-Flux Isotope Reactor (HFIR) as a world-class neutron sources and user facilities. We strive towards delivering highest-intensity neutron beams from the source to the instruments, ensure that the instruments are shielded to meet the radiation protection requirements, and minimize the radiation induced background in the scattering instruments. Also, we cover the neutronics analysis aspects of the neutron source life cycle from optimizing neutron beam production to the disposal of the highly activated components at their end of service life. Upgrade projects are currently in progress to improve the neutron source facilities, both HFIR and SNS, to maintain the US and ORNL leadership in neutron scattering science. You will be working in a multidisciplinary team of scientists, engineers, and designers, and apply your nuclear analysis skills to finding solutions for challenging problems that we are facing at our facilities. 

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. 

Major Duties/Responsibilities:   

• Perform neutronic analyses with state-of-the-art Monte Carlo radiation transport codes to calculate quantities of interest such as moderator neutron performance, radiation-induced material damage estimates, and nuclear heating. 

• Contribute with nuclear design analyses to projects working in interdisciplinary teams with engineers and designers. 

• Communicate your findings and analyses reliably to your collaborators and ORNL management. 

• Prepare technical reports, documentation, and presentations for design reviews and management. 

• Develop shielding solutions for SNS target station systems, neutron beamlines, and scattering instruments. 

• Contribute to the development and maintenance of nuclear analysis tools and nuclear data to support the Group's complex analysis needs and the overall research and development efforts of the organization. 

• Display ES&H understanding and discipline that leads to outstanding safety performance. 

• Maintain the highest ethical and professional standards of performance and operate in accordance with these standards. 

• Represent SNS Neutronics in presenting your work at meetings, workshops, and conferences. 

• Publish results in scientific journals, conference proceedings and ORNL technical reports as appropriate. 

• 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 encouraging a respectful workplace – in how we treat one another, work together, and measure success.  

Basic Qualifications: 

• A PhD in nuclear engineering or physics with degree focus on neutronics analyses (an MS will be considered with at least 2 years of relevant post graduate experience). 

• Familiarity with Monte Carlo techniques in particle transport. 

• Experience in shielding analysis and design. 

• Programming experience with C, Fortran, Perl and/or Python and working experience on Linux/Unix computer platforms. 

Preferred Qualifications: 

• Experience working in nuclear, accelerator, or neutron science facilities. 

• Good written and oral communication skills. 

• Project management skills. 

• Nuclear data library management. 

Special Requirements: 

This position requires access to technology that is subject to export control requirements. Successful candidates must be qualified for such access without an export control license.
