Terra Power is seeking to hire highly motivated and forward‑thinking professionals who are interested in focusing on advanced nuclear reactor research and development and influencing change within the nuclear power landscape and bringing forward the critical production of medical isotopes. Terra Power is an Equal Opportunity Employer. We do not discriminate in hiring on the basis of sex, gender identity, sexual orientation, race, color, religious creed, national origin, physical or mental disability, protected Veteran status, or any other characteristic protected by federal, state, or local law.

Terra Power, LLC. is seeking a highly motivated Nuclear Design Engineer. The Nuclear Analysis Engineer will support advanced reactor core design and analysis activities, including fuel management, power distribution, reactivity coefficients, control rod worth, shutdown margin, and sensitivity/uncertainty studies. This role will contribute to nuclear design solutions, evaluate modeling assumptions, document analysis results, and support the development of methods needed to solve complex reactor design challenges.

• Perform core design and analysis activities of advanced nuclear reactors, including calculation and optimization of fuel management, power distributions, reactivity coefficients, control rod worth and shutdown margin, sensitivity and uncertainties, consistent with required functional and quality requirements
• Design and analyze new systems for solving complex problems
• Design and execute sensitivity studies to understand the effects and validity of various modeling assumptions, including meshing, physics coupling, transport options, cross section preparation, fission product treatment, spatial kinetics, etc., and help build corrected methods if necessary
• Establish and maintain documentation of analysis results and nuclear design solutions
• Work at Terra Power is dynamic and evolutionary. As such, new responsibilities often arise, and you should be capable of and excited about learning and applying specialized skills

• Experience:
  • B.S. degree in Nuclear Engineering with 5-20 years' experience
  • M.S. degree in Nuclear Engineering with 3-15 years' experience
  • Ph.D. degree in Nuclear Engineering with 2-10 years' experience
  • Competitive candidates will typically have the above experience, but less experienced candidates with highly desired experience will be considered on a case‑by‑case basis
• Knowledge of basic nuclear reactor design concepts to meaningfully support engineering team with understanding of systems being designed and code being reviewed
• Experience in core design and analysis including fuel management optimization, reactivity coefficients, shielding and activation, control rod worth and uncertainty analysis
• Strong computational expertise: we like to consider computers as the universe at our fingertips rather than burdensome necessities
• Experience with nuclear engineering software such as MCNP, DIF3D, MC2, PARTISN, RELAP, SCALE, PARCS, APA, CASMO/SIMULATE, DRAGON, etc.
• Good working knowledge of nuclear and/or general numerical methods (e.g. PDEs, dynamics, deterministic and stochastic particle transport, isotopic depletion, perturbation theory, nuclear data, kinetics, etc.)
• Experience in transient analysis, thermal hydraulics, fuel performance, etc. is desired
• Fast reactor experience or experience with Core Operating Limits Report/Tech Specs is desired
• Excellent verbal and communication skills
• Ability and professionalism to work within published regulatory guidelines for nuclear reactor design
• An ability to perform professional‑quality software development for nuclear applications is preferred
• Strong programming skills in any language is a plus
• Experience working in NQA‑1 environments desired
• Maintain software by working with team to implement clearly defined…
