Export Control Manager Jobs in Tennessee (NOW HIRING)

Spectra Tech, Inc. is hiring a detail-oriented Nuclear Structural Engineer to support the HFIR Beryllium Reflector Replacement (HBRR) Project in Oak Ridge, TN. APPLY TODAY!

Operating at 85 MW, the High Flux Isotope Reactor (HFIR) is the highest flux reactor-based source of neutrons for research in the United States and provides one of the highest steady-state neutron fluxes of any research reactor in the world. The thermal and cold neutrons produced by HFIR are used to study physics, chemistry, materials science, engineering, and biology.

Spectra Tech, Inc. supports operations and upgrade activities associated with HFIR. The HFIR Upgrades Project Office manages the HFIR Beryllium Reflector Replacement (HBRR) Project, which is being prepared for a major extended outage scheduled for 2029.

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.

Applicants must have 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.

This position will be assigned to the Plant Life Extension Section and will interact with the HFIR Upgrades Project Office supporting HBRR activities.

This position requires access to technology that is subject to export control requirements. Successful candidates must be qualified for such access without an export control license.

This position may require participation in a Workplace Substance Abuse Program (WSAP), which includes passing a pre-placement drug test and participation in an ongoing random drug testing program.
