• Demonstrated effectiveness at system design and evaluation.
• Demonstrated effectiveness with project completion and implementation.
• Proven experience with design of reactor vessels using ASME BPVC with high temperatures accounting for creep and fatigue.
• Proven experience with design of high temperature gaskets, sealing, and bolting
• Document the design of electromechanical devices (controlled and approved models, drawings, specifications, design descriptions) such as control rod/drum drive mechanisms to establish conformance with design requirements and applicable codes and standards.
• Decompose project objectives into defined and controlled design requirements using a systems engineering approach and applying digital engineering tools for tracking requirements and design parameters.
• Use design methodologies, technologies, and processes which are best practice for the technical discipline to develop and define a design, and to validate that the design meets defined requirements.
• Establish testing, inspection, and quality requirements to ensure technical features important to design functions are maintained.
• Oversee or otherwise ensure that fabrication, construction, assembly, and procurement are done in accordance with the design.
• Ensure any design meets the technical baseline requirements and applicable codes and regulations.
• Develop, ensure adequacy of, and maintain configuration management of the technical baseline. Establish and maintain configuration management of assigned system.
• Ensure consistency in operation characteristics among applicable documents such as drawings, technical manuals, operating instructions, emergency operating procedures.
• Work with other designers, customers, and analysts to develop experiment requirements, perform conceptual and final designs, follow all fabrication and inspection activities, lead experiment assembly activities, support installation and testing of experiments, and support development of integrated analyses to ensure that facility safety bases are met.
• Responsible for design and fabrication and associated activities leading to reactor operations and experimentation.
• Other duties as assigned by the Lead Reactor Project Engineer or the Engineering Manager.
