Description of Institution

The Neutron Sciences Directorate (NScD) at Oak Ridge National Laboratory (ORNL) operates the High Flux Isotope Reactor (HFIR), the United States’ highest flux reactor based neutron source, and the Spallation Neutron Source (SNS), the world’s most intense pulsed accelerator based neutron source. Together these facilities operate 27 instruments for neutron scattering research, each year carrying out in excess of 1,000 experiments in the physical, chemical, materials, biological and medical sciences. HFIR also provides unique facilities for isotope production and neutron irradiation. To learn more about Neutron Sciences at ORNL go to: http://neutrons.ornl.gov.

Job description

In this role you will perform engineering analysis on a wide variety of systems in support of the SNS neutron source systems, including high power targets, and moderator and reflector plug assemblies. These systems receive pulsed, high power, high energy proton beams and are first-of-a-kind systems that have unique design issues, requiring innovative approaches and methods of analysis and simulation. The Mechanical Engineer also performs technical analysis of existing and proposed designs using established methods as well as developing and improving analysis methods and processes. Participate in planning and evaluation activities.

Major Duties/Responsibilities

  • Perform detailed engineering analysis of existing and new target systems of a high power pulsed 1 GeV proton accelerator, and its auxiliary systems.
  • Work with design engineers to develop and analyze design concepts and resolve issues found by analysis.
  • Continuously improve analysis methods and processes based on evolving state of the art and feedback from SNS operating experience and experimental data.
  • Produce accurate and concise technical reports and other communications.
  • Perform review of technical reports created by others.
  • Accurately and reliably communicate technical status and performance to ORNL management.
  • Comply with ORNL environment, safety, health, and quality program requirements.
  • Maintain a strong commitment to the implementation and perpetuation of ORNL values and ethics.

Requested Profile

Qualifications Required
MS in mechanical engineering or engineering science and a minimum of 3 years in applicable mechanical engineering analysis experience. Must have a sound understanding of structural mechanics, fluids, heat transfer, and materials and have the ability to quickly grasp complex technical problems. Must be able to technically analyze engineering systems and communicate results. Must be willing and able to learn new analysis methods and related skills needed to provide broad analysis support for SNS systems. Must have excellent communication skills and the ability to work both independently and as part of a diverse team consisting of scientific specialists, engineers and designers to meet project cost and schedule goals. Proficient knowledge of finite element mechanical simulation required (ANSYS, ABAQUS, or similar).

Preferred Qualifications

  • Familiarity with the ASME Boiler and Pressure Vessel Code.
  • Experience in explicit finite element simulations such as ABAQUS / Explicit, Autodyn, LS-DYNA, etc.
  • Experience with computational fluid dynamics (ANSYS CFX, etc) is a plus.
  • Experience with hexahedral meshing (ICEM CFD Hexa, Truegrid, etc.).
  • Professional engineer certification is desired.
  • Proficiency with CAD and design experience.

Work Directions and Interfaces
This position reports to the Source Development and Engineering Group Leader. The person in this role will also work with personnel in ISD and other divisions in SNS.
Authority/Approval Levels: Responsible for content of created technical reports.

Measures of Effectiveness

  • Successfully performs analysis needed to support design and evaluation of SNS target system equipment.
  • Successfully improves analysis methods and processes.
  • Successfully interacts with engineers and physicists throughout the facility to provide needed analysis support and feedback on design concepts.
  • Successfully records and reports analysis results to SDE and division management and review committees.
  • Demonstrates technical competence.
