JOB DESCRIPTION

Position Title:

Lead Fuel Design Engineer

Position Description:

Protingent Staffing has an exciting direct hire Lead Fuel Design Engineer opportunity.

Job Responsibilities:

Design Ownership & Iteration:

Serve as the primary design authority for the KRONOS hexagonal prismatic fuel elements, owning the specifications for coolant channels, burnable poison locations, and dowel/socket alignment features.

Cross-Functional Integration:

Collaborate directly with fuel performance and thermal-hydraulics engineers analyze how proposed physical modifications to fuel specifications alter thermal-mechanical behavior and core reactivity.

Drawing & Specification Control:

Author, update, and rigorously control all 3D engineering models, 2D manufacturing drawings, and geometric dimensioning and tolerancing (GD&T) for the fuel assemblies.

Regulatory & Empirical Adaptation:

Implement necessary design modifications driven by iterative regulatory feedback, vendor fabrication constraints, and empirical data generated from ongoing irradiation testing campaigns.

Configuration Management:

Anchor all CAD models, technical drawings, and design modifications within Siemens Teamcenter, ensuring strict adnce to nuclear Quality Assurance standards for product lifecycle management.

Qualification Design Basis:

Own the traceability from fuel functional requirements and safety-analysis limits to controlled drawings, material specifications, acceptance criteria, and qualification test-article configurations. Assess whether manufactured and irradiated specimens remain representative of the licensed KRONOS fuel design.

Job Qualifications:

Education:

Bachelor's or Master's Degree in Mechanical Engineering, Nuclear Engineering, Aerospace Engineering, or a strictly related highly technical discipline.

Nuclear Fuel Design Experience:

7+ years of experience in engineering design, with direct responsibility for nuclear fuel, reactor internals, graphite or ceramicponents, orparable safety-significant hardware. With demonstrated proficiency in advanced 3D CAD software and enterprise Product Lifecycle Management. Proven ability to translateputational performance data and experimental feedback into actionable, physical design modifications

Qualification Specimen Definition:

Demonstrated ability to convert design requirements into specimen configurations, manufacturing specifications, inspection criteria, interface-control documents, and as-built acceptance records for irradiation or safety testing.

Design Control:

Working knowledge of ASME NQA-1 or 10 CFR Part 50 Appendix B design-control practices, including design inputs, independent verification, interface control, configuration management, and change-impact assessment.

Fuel Requirements Traceability:

Experience maintaining traceability among functional requirements, drawings, material and process specifications, analysis assumptions, test conditions, acceptance criteria, and safety limits.

Manufacturing & Metrology:

Practical experience resolving manufacturability, tolerance, inspection, and metrology issues without invalidating design margins or qualification representativeness.

Preferred Job Qualifications

Direct applied experience designing nuclear fuel assemblies, high-temperature ceramicponents, orplex graphite structures.

Familiarity with

ASME NQA-1

quality assurance requirements, specifically regarding formal design control, verification, and documentation.

Background in extreme-environment mechanical design derived from parallel industries (e.g., aerospace thermal protection, defense) transitioning into the nuclear sector.
