Fuel Materials Scientist

NANO Nuclear Energy is seeking a Fuel Materials Scientist to play a central role in the development and qualification of fuel for the KRONOS MMR.

This is an opportunity for an experienced materials scientist or nuclear fuel specialist to move beyond individual testing activities and take broader ownership of the experimental, characterization, fabrication, and scale-up strategies supporting an advanced reactor program.

Reporting to the Reactor Fuel Design Manager, you’ll focus on TRISO particle fuel within a ceramic matrix, with particular emphasis on the thermomechanical behavior of silicon carbide (SiC) produced through Chemical Vapor Infiltration (CVI).

Your work will help establish the material qualification basis needed to demonstrate fuel performance under normal, transient, and accident conditions while supporting the progression from experimental development toward scalable fuel production.

• Own high-impact materials qualification work supporting an advanced nuclear reactor program.
• Design experimental campaigns addressing critical thermomechanical data gaps for CVI SiC.
• Work directly across TRISO fuel, ceramic-matrix materials, irradiation testing, characterization, and fabrication.
• Influence fuel specifications and qualification strategies using empirical test data.
• Gain direct exposure to external fabrication partners and irradiation campaigns.
• Help translate advanced materials R&D into controlled, reproducible manufacturing processes suitable for future scale-up.

• Design and execute experimental campaigns to characterize the thermomechanical properties of CVI SiC under simulated extreme operating and accident conditions.
• Contribute directly to the planning and execution of fuel irradiation campaigns.
• Evaluate empirical results and translate findings into modifications to fuel specifications and qualification requirements.
• Oversee external fuel fabrication activities with strategic vendors.
• Develop and validate destructive and nondestructive fuel characterization methods.
• Establish material attributes, process parameters, characterization methods, sampling plans, and acceptance criteria for TRISO particles and ceramic-matrix fuel.
• Demonstrate that fuel lots are representative, reproducible, and suitable for irradiation and safety-test qualification credit.
• Support fabrication and process scale-up strategies as fuel development progresses toward larger-scale production.

• Advanced degree in Materials Science, Nuclear Engineering, Chemical Engineering, or a closely related technical discipline;
  Ph.D. preferred.
• 5+ years of experience in nuclear fuel, coated-particle, ceramic, or composite materials characterization and testing.
• Direct knowledge of TRISO kernel and coating-layer attributes, SiC or ceramic-matrix processing, defect mechanisms, microstructure, thermophysical properties, irradiation behavior, and high-temperature degradation.
• Demonstrated experience developing, validating, and transferring destructive and nondestructive characterization methods.
• Knowledge of calibration, measurement uncertainty, detection limits, repeatability, reproducibility, and reference standards.
• Experience defining material lots, statistically defensible sampling plans, acceptance criteria, defect populations, and data‑reduction methods for heterogeneous or low‑defect‑rate fuel products.
• Experience conducting qualification work under ASME NQA-1, 10 CFR Part 50 Appendix B, or equivalent nuclear QA controls.
• Strong understanding of specimen identity, chain of custody, data…
