The ideal candidate will have a strong background in welding and joining techniques, combined with a solid understanding of machine design principles.
• This role requires a comprehensive knowledge of ASME Boiler and Pressure Vessel Codes (Sections III and VIII) and ASME B31.1 piping codes, with proven ability to apply these standards in practical scenarios. The position involves performing and reviewing piping analyses and calculations in compliance with HFIR Safety Basis Procedures and applicable Department of Energy (DOE) standards and guidelines.
• Additionally, this role will support efforts to restore HFIR's operating power from 85 MW back to 100 MW as part of the PVR Project. This project is currently in the early stages of Critical Decision-1 (CD-1), as defined by DOE Order 413.3B.
• Apply engineering expertise to support HFIR operations.
• Prepare engineering designs for new installations and for replacement or upgrade of HFIR structures, systems, and components (SSCs).
• Perform calculations and analyses to support design basis and requirements.
• Apply relevant codes and standards, including ASTM, ASME Boiler and Pressure Vessel Code, ASME B31 piping codes, NQA-1, AWS, etc.
• Support development of reactor core component replacement plans.
• Prepare design specifications and define acceptance criteria for component upgrades.
• Update material specifications and provide technical support for material procurement.
• Implement modifications in accordance with RRD configuration control processes.

Requirements

• Bachelor\'s degree in mechanical engineering, nuclear engineering, or related discipline
• Minimum of 10 years in DOE nuclear facilities and/or commercial nuclear plants.
• Comprehensive understanding of nuclear technology, including reactor safety basis, design, and construction.
• Proficiency in engineering design and manufacturing practices, including welding and joining techniques and machine design.
• Familiarity with DOE Orders and Standards (e.g., DOE O 420.1C, DOE STD 1189, DOE STD-1073-2016).
