The job description

Tech stack. Fuel fabrication processes, enrichment cascade modeling, spent fuel storage analysis, MCNP for criticality, transportation cask licensing, burnup credit methods, Python for inventory modeling

About the role

You will engineer the full journey of nuclear fuel for a fuel cycle company, from enrichment through fabrication, reactor use, storage, and disposition. The team ensures fuel moves safely and economically through every stage while meeting safeguards and regulatory requirements. You will analyze storage systems, support transportation licensing, and optimize the back end of the fuel cycle. This role matters because the fuel cycle is where nuclear energy meets long-term stewardship, and your engineering keeps every stage safe, secure, and publicly defensible. You will also evaluate emerging fuel cycle technologies such as advanced reprocessing and accident-tolerant fuels for their operational implications. Your lifecycle cost analyses will inform strategic decisions about storage investments that must remain valid for decades. You will interface with safeguards inspectors demonstrating that material control and accounting meets international obligations. Your knowledge of the full fuel cycle will make you the connective tissue between reactor operations, waste management, and long-term planning teams.

What you will achieve

Complete spent fuel storage analyses supporting license renewals with thermal and criticality margins documented.
Support transportation package licensing with shielding and criticality evaluations the NRC accepts cleanly.
Optimize fuel inventory management reducing carrying costs while maintaining required reload coverage.
Develop burnup credit methodologies that increase storage capacity without new construction.
Deliver safeguards analyses demonstrating material control and accounting meets all regulatory requirements.

What you will bring

Must-haves

2 to 5 years in fuel cycle engineering, fuel fabrication, or spent fuel management roles.
Understanding of the full fuel cycle: enrichment, fabrication, irradiation, storage, and disposition options.
Experience with criticality safety methods and codes such as MCNP or SCALE for storage and transport.
Knowledge of NRC regulations for fuel cycle facilities and transportation under 10 CFR 71 and 72.
Ability to perform thermal analyses of dry storage systems and decay heat removal.
Understanding of nuclear material safeguards, accounting, and physical protection requirements.
Systems thinking: you see how decisions at one fuel cycle stage affect all the others.

Nice-to-haves

Experience with reprocessing, recycling, or advanced fuel cycle concepts.
Familiarity with DOE spent fuel management programs and policies.
Knowledge of high-burnup fuel behavior and storage implications.
Experience with cask vendor qualification or fabrication oversight.
