Does a career focused on changing the world's energy future intrigue you? If so, we might have just the opportunity you're looking for!
Idaho National Laboratory's (INL) Computational Mechanics and Materials group is seeking forward-thinking professionals interested in exploring a career as a Computational Scientist.
Our team works an on-site 9x80 schedule located at our Research Education Campus with every other Friday off!
Responsibilities Include:
This position is centered in our nuclear fuel performance software development team (bison.inl.gov). The modeling and simulation engineer in this role will develop, support, maintain, document, and use our fuel performance software. This position resides in the Computational Mechanics and Materials Department in the Nuclear Fuel and Materials Division, Nuclear Science and Technology Directorate.
The Bison fuel performance code is applicable to a range of fuel forms (light-water reactor, TRISO, metallic, etc.). The team performs research and development on improved models for each of these fuel forms. The person in this position will work as part of the Bison team to improve our ability to model nuclear fuel.
Experience in the following areas is needed: fuel performance modeling, particularly involving Bison; constituent redistribution in metallic fuels; the relationship between meso-scale material behavior and model development (e.g., the use of the phase field method) to the engineering scale; homogenization techniques; development of engineering scale thermal and mechanical models of nuclear materials; use of coupled codes in nuclear fuel analysis; and project management including work scope development, budgeting, and communication of research results.
Success in this role will be connected with enjoying computational analysis and problem solving. General experience with the finite element method for solid mechanics and heat conduction analysis is essential. The position involves software testing on a variety of platforms, including Mac OS and Linux on distributed memory clusters. The engineer will regularly use test driven development, agile software methods, git, C++, Python, and software quality practices.
This position involves software verification, validation, and uncertainty quantification. The engineer will have a knowledge of (or will learn) verification practices and techniques (e.g., proper orders of convergence with mesh refinement and the method of manufactured solutions). The engineer will perform validation work in which experimental data is compared to computationally predicted behavior. The engineer will apply uncertainty quantification techniques. All of this will be done to provide increased confidence to Bison users of Bison results.
Minimum Requirements:
  • PhD in physics, materials science, nuclear engineering or a related field, plus a minimum of two years of directly relevant experience
Preferred Requirements:
  • Experience using Bison
  • Experience with C++, Python, and Linux/MacOS
  • Experience writing finite element software
  • Experience modeling material behavior
  • Be a strong asset to our mature, high-energy R&D team and work effectively in isolation, as a team member, and as a research project leader
  • Document work, including in manuals, conference papers, and refereed journal articles
  • Maintain a record of sponsor satisfaction and support
  • Provide peer review of research internal and external to INL
  • Develop plans for new research areas
  • Mentor summer students, postdoctoral researchers, and other staff by providing technical guidance
Job Information
  • Salary Grade: 220
  • Chosen applicants are required to show a demonstrated commitment to valuing diversity and contributing to an inclusive working environment
