About The Position

XCEL Engineering, Inc. is an award-winning small business that provides trusted information technology, engineering, consulting and project management solutions and services to federal agencies and organizations. Originally founded in 1971 by professional engineers at the University of Tennessee, XCEL was acquired in 2003 by U.S. Army and Navy veterans and in 2023 became a MartinFed company. XCEL Engineering is a part of IT Lab Partners (ITLP) which was created to support a leading research facility in the East Tennessee region in recruiting the best and the brightest technical talent. Considering joining our impressive team today! XCEL Engineering is seeking a qualified applicant for a highly skilled HFIR Nuclear Structural Engineer with a minimum of 10 years of experience in areas such as facility seismic upgrades and implementations, as well as the analysis and modification of existing building structures. This position also requires performing and reviewing structural calculations in compliance with HFIR Safety Basis Procedures and applicable Department of Energy (DOE) standards and guidelines. ORNL is currently preparing for two exciting major replacement projects, the reactor pressure vessel and the beryllium reflector, to sustain and enhance HFIR's operation performance. Both projects require engineering, design, and analysis support to complement the integrated project team to deliver the design milestones on schedule and within scope. Specifically, the individual will be working closely with system engineers, designers, and various other disciplines within RRD. This position will be assigned to the HFIR Upgrades Project Office and interacts with personnel at all levels within HFIR. The purpose of the HBRR Outage is to replace the life limiting beryllium reflector along with other critical reactor vessel components, enabling continued reactor operations for another 20 years. Preparatory activities for this outage will span several years. Outage preparation activities include the design and fabrication of custom lifting devices and fixtures, as well as performing structural analyses and calculations to support ongoing HBRR fabrication activities. Additionally, these activities require providing input for lift plans related to reactor component assembly procedures and ensuring full compliance with ASME B30.20 standards for Below-the-Hook Lifting Devices.

Requirements

• US Citizen with the ability to obtain a security clearance.
• B. S. degree in Civil Engineering with a strong structural background and a minimum of 10 years of experience in the DOE's nuclear facilities and/or the commercial nuclear plants; M.S. degree preferred.
• Must be highly knowledgeable and proficient in material designs such as steel, masonry, concrete, and cold formed metal design.
• Must possess a strong understanding of material handling practices and the various lift classifications as defined in ORNL SBMS.
• Requires proficiency in applying AISC, ACI, AWS, ASCE, ANSI, and other relevant codes and standards for nuclear facility design.
