Oak Ridge National Laboratory

Requisition Id 14871

Overview:

Are you ready to make a lasting impact on groundbreaking neutron-based research and isotope production with a uniquely powerful nuclear reactor? Oak Ridge National Laboratory (ORNL) is seeking a Nuclear Reactor Analysis Lead who is responsible for leading reactor design and safety analysis, conducting technical evaluations, and leading engineering design reviews in the High Flux Isotope Reactor (HFIR) Upgrades Project Office (HUPO). HFIR is a light-water cooled and moderated research reactor that began full-power operations in 1966 at the design power level of 100 megawatts. Currently, as the most powerful continuously operating neutron source in the United Stated, HFIR operates at 85 megawatts providing state-of-the-art facilities for neutron scattering, materials irradiation, and neutron activation analysis. It is the world's leading source of elements heavier than plutonium for research, medicine, and industrial applications. You'll play a crucial role in initiatives like the $200+ Million HFIR Beryllium Reflector Replacement (HBRR) and the $700+ Million Reactor Pressure Vessel Replacement (PVR). With the PVR project, ORNL will restore HFIR to 100 MW for full power operations, implement design enhancements for further improve neutron science capabilities, and apply state-of-the-art tools to modernize the safety basis with best estimate plus uncertainty analysis.

The Nuclear Reactor Analysis Lead ensures reactor performance meets operational objectives while maintaining full compliance with nuclear safety regulations. This role will supervise a team of direct report and matrixed engineers in fields such as reactor physics, radiation shielding, thermal hydraulics, and reactor control. Additionally, this position collaborates with regulatory bodies, contributes to safety and compliance documentation, and enforces meticulous quality control measures.

This position resides in the Nuclear Project Director’s Office in the HFIR Updates Project Office, Neutron Upgrades Project Office, at ORNL. Be part of the future of scientific innovation! Join us at nation's most powerful continuous neutron research facility to drive scientific competitiveness and unlock groundbreaking opportunities for the country.
