Senior Reactor Fuel Engineer
About the role
Lead the Experimental Program Behind Advanced Reactor Fuel Qualification The Opportunity Take ownership of the irradiation, post-irradiation examination (PIE), and safety-testing program supporting qualification of the ceramic matrix TRISO fuel architecture for the KRONOS High-Temperature Gas-Cooled Reactor (HTGR). Reporting to the Reactor Fuel Design Manager, you’ll lead a multidisciplinary, multi-institution experimental program spanning specimen selection and irradiation planning through test execution, PIE, high-temperature safety testing, and delivery of qualification-grade evidence. This is an opportunity for an experienced nuclear fuels professional to move beyond individual experiments and take broader ownership of an integrated fuel qualification program while working directly with research reactors, national laboratories, universities, hot cells, testing laboratories, and other technical partners. Why This Opportunity Stands Out End-to-end ownership: Guide the experimental program from test strategy and specimen definition through irradiation, PIE, safety testing, and final evidence delivery. Advanced fuel technology: Work directly with ceramic matrix TRISO fuel supporting an advanced HTGR. Broad technical exposure: Integrate irradiation testing, dosimetry, instrumentation, thermal analysis, fission-product monitoring, PIE, and accident-condition testing. External collaboration: Work across research reactors, national laboratories, universities, hot cells, analytical laboratories, and testing facilities. Technical
