Postdoctoral Research Associate - Advanced Reactor Core Materials Characterization

Requisition Id15473

Overview:

Oak Ridge National Laboratory is the largest US Department of Energy science and energy laboratory, conducting basic and applied research to deliver transformative solutions to compelling problems in energy and security.

We are seeking a Postdoctoral Research Associate who will aid the research staff in understanding the synergistic effects of various degradation phenomena of nuclear reactor fuel cladding and core internal materials. Strong materials characterization skills are required. This position resides in the Fuel Cladding and Core Internals (FCCI) Group in the Nuclear Energy and Fuel Cycle Division, Fusion and Fission Energy and Science Directorate at Oak Ridge National Laboratory (ORNL).

The FCCI Group applies modern materials science to design, develop, optimize, and test advanced materials that will accelerate the deployment of higher performance nuclear energy systems. As part of our research team, you will evaluate accelerated testing methods (in-situ deformation + irradiation and/or corrosion) that affect the performance of structural materials deployed in extreme operating conditions and develop advanced characterization techniques to achieve these goals. You will also assess the viability of accelerated irradiation methodologies (either using ions or research reactor irradiation data) for establishing performance envelopes for materials to be deployed in advanced reactors. Efforts would in-part utilize the instrumentation and expertise available through the Low Activation Materials Development and Analysis Laboratory (LAMDA). The selected individual will be encouraged to engage with staff within the FCCI group, Nuclear Fuel Development section and across the laboratory to foster a vibrant research atmosphere to grow capabilities and drive innovation.

Metrics for success will include scientific output, disseminating results at national and international conferences and other technical meetings, and delivering on programmatic milestones.

Major Duties/Responsibilities:

• Utilize techniques such as optical microscopy, scanning electron microscopy (SEM), electron backscatter diffraction (EBSD), and transmission electron microscopy (TEM) for microstructural characterization of materials.
• Correlate irradiation conditions to the post-irradiation performance of novel materials.
• Assist in the demonstration of in-situ experiments to probe simultaneous corrosion/creep and irradiation/creep phenomena.
• Perform characterization activities within a radiological laboratory.
• Participate in the development of new ideas and projects.
• Present and report research results and publish scientific outcomes in peer-reviewed journals in a timely manner.
• Ensure compliance with environment, safety, health, and quality program requirements.
• Maintain strong dedication to the implementation and perpetuation of values and ethics.
• Collaborate within a multi-disciplinary research environment consisting of experimentalists, computational scientists, and engineers conducting basic and applied research in support of the Laboratory's missions.
• Deliver ORNL's mission by aligning behaviors, priorities, and interactions with our core values of Impact, Integrity, Teamwork, Safety, and Service. Promote equal opportunity by fostering a respectful workplace - in how we treat one another, work together, and measure success.

Basic Qualifications:

• A PhD degree in materials science, nuclear, or mechanical engineering, or a related discipline within the past 5 years.
• Excellent communication skills, including verbal, presentation, and writing skills, are required to enable effective interaction with technical peers and program managers.
• Applicants must have completed all degree requirements prior to position start.

Preferred Qualifications:

• Proficiency with specimen preparation using standard metallography and Focused Ion Beam (FIB) techniques.
• Proficiency with characterization techniques such as SEM, EBSD, and TEM is strongly preferred.
• Experience with radiation effects in metals and alloys, with a particular focus on damage-rate and/or helium effects in materials.
• Familiarity with subsized specimen mechanical testing/property analysis.
• Experience with the design of experiments for the collection of in-situ mechanical testing data.
• Knowledge of scientific software in python (numpy, scipy, pandas) or related data analysis suite.
• Record of productive and creative research as demonstrated by publications and conference presentations.
• Motivated self-starter with the ability to work independently and to participate creatively in collaborative teams across the laboratory.
• Ability to function well in a fast-paced research environment, set priorities to accomplish multiple tasks within deadlines, and adapt to ever changing needs.

Applicants cannot have received their Ph.D. more than five years prior to the date of application and must complete all degree requirements before starting their appointment. The appointment length will be up to 24 months with the potential for extension. Initial appointments and extensions are subject to performance and availability of funding.

Special Requirements:

• Physical Requirements: Work involves various physical requirements and working conditions. As such, a pre-hire physical will be required after offer.

Security, Credentialing, and Eligibility Requirements:

• This position requires the ability to obtain and maintain an HSPD-12 PIV badge.
• For employment at Oak Ridge National Laboratory (ORNL), a Real ID compliant form of identification will be required.
• Additionally, ORNL is subject to Department of Energy (DOE) access restrictions. All employees must also be able to obtain and maintain a federal Personal Identity Verification (PIV) card as mandated by Homeland Security Presidential Directive 12 (HSPD-12) and Department of Energy (DOE) Order 473.1A, which requires a favorable post-employment background investigation.
• To obtain this credential, new employees must successfully complete and pass a Federal Tier 1 background check investigation. This investigation includes a declaration of illegal drug activities, including use, supply, possession, or manufacture within the last year. This includes marijuana and cannabis derivatives, which are still considered illegal under federal law, regardless of state laws.

For foreign national candidates:

• If you have not resided in the U.S. for three consecutive years, you are not eligible for the PIV credential and instead will need to obtain a favorable Local Site Specific Only (LSSO) risk determination to maintain employment.
• Once you meet the three-year residency requirement, you will be required to obtain a PIV credential to maintain employment.
