Apply now »

Date: Nov 30, 2018

Location: Oak Ridge, TN, US, 37831-6145

Company: Oak Ridge National Laboratory

Requisition Id 336 


The Reactor and Nuclear Systems Division (RNSD) at Oak Ridge National Laboratory (ORNL) seeks applications for the position of Senior Staff Member.

The primary mission of the Used Fuel Systems (UFS) group is to develop and provide science-based engineering solutions, nuclear safety analysis capabilities, and technical leadership and support for the safe, secure, and effective management and disposition of spent nuclear fuel (SNF) and high-level radioactive waste (HLW). The UFS group leads, manages, and conducts basic and applied research and development projects focused on the continued safe storage, transportation, and geologic disposal of SNF. These projects include the development of integrated system solutions for SNF and HLW. This position will report to the Used Fuel Systems Group Leader and will collaborate closely with other ORNL groups in areas such as SNF characterization, criticality safety, thermal analyses, radiation shielding, systems analyses, facility design, material performance, destructive and nondestructive SNF measurements, and material safeguards and security.


Major Duties/Responsibilities

  • Collaborate within a multidisciplinary, multilaboratory research environment consisting of computational scientists, computer scientists, experimentalists, and engineers/physicists conducting basic and applied research for solving technical problems for engineering or technical projects and functions supported
  • Participate in and lead large complex nuclear safety analyses focusing on integrated spent fuel storage, transportation, and disposal applications
  • Represent work performed by the group for internal and external review, providing presentations to sponsors and the general public as necessary
  • Author technical papers, reports, and proposals for internal and external release, and represent the organization and sponsors via technical presentations in workshops and conferences
  • Communicate regularly with sponsors, regulators, and other stakeholders

Qualifications Required

Basic Qualifications:

  • Must have a bachelor’s degree in mechanical, nuclear, or similar engineering discipline.
  • Must have 12 or more years of experience in performing nuclear safety analysis, three of which include experience in SNF management and disposition technologies and a demonstrated understanding of commercial SNF and SNF storage and transportation systems, technologies, and regulations
  • Must be organized, detail-oriented and sensitized to a nuclear safety culture
  • Requires excellent interpersonal, presentation, and writing skills to enable effective interaction and communication with technical peers, program managers, and sponsors
  • Expertise is required in one or more of the following as relevant to application areas of interest
    • nuclear reactor reload/core follow analyses
    • nuclear safety analysis supporting licensing interactions
    • verification, validation, and uncertainty quantification methodologies
    • burnup credit
    • criticality safety
    • shielding analysis
    • confinement/containment analysis
    • thermal analysis
  • Must have experience in the design and implementation of numerical algorithms in one or more high-level computing languages (e.g., C++, Fortran, Python).
  • This position will provide technical analyses as needed
  • The successful candidate will ensure compliance with environment, safety, health and quality program requirements
  • This position requires the ability to obtain and maintain a clearance from the Department of Energy. As such, this position is a Workplace Substance Abuse (WSAP) testing designated position. WSAP positions require passing a pre-placement drug test and participation in an ongoing random drug testing program

Preferred Qualifications

  • Experience working in a multidisciplinary team environment to address the requirements of 10 CFRs 50, 71, and 72 and existing regulatory guidance
  • Basic software design education or experience, including generic programming, object-oriented analysis, and scripting languages
  • Understanding of verification and validation; the relationship between theory, experiments, and simulation; and visualization and interpretation of simulation data
  • Demonstrated ability to generate source terms for specific reactor operating conditions and apply them for performing nuclear safety analyses (e.g., criticality, shielding, thermal)
  • Experience in thermal-hydraulics analysis for both reactors and dry storage systems
  • Working knowledge of industry operations and practice for spent fuel management, including ASME NQA-1 quality assurance program requirements
  • Experience and demonstrated success in project management, program development, and leading multidisciplined technical staff members to work in a team environment
  • Prior experience participating in engineering design teams developing technical specifications, topical reports, and safety analysis reports (SARs)
