What is the difference between Full Time Reactor Physics vs Reactor Operations Technician?

AspectFull Time Reactor PhysicsReactor Operations Technician
Required CredentialsAdvanced degrees in nuclear engineering or physics, certifications in reactor safetyTechnical diploma or associate degree, on-the-job training
Work EnvironmentResearch facilities, nuclear power plants, analytical labsControl rooms, plant floors, operational settings
Employer & Industry UsageResearch institutions, nuclear power industry, government agenciesNuclear power plants, operational support teams

Full Time Reactor Physics roles focus on analyzing reactor behavior, safety analysis, and core design, often requiring advanced degrees. Reactor Operations Technicians handle day-to-day plant operations, monitoring systems, and safety procedures. While both work within the nuclear industry, their responsibilities, credentials, and work environments differ significantly.

Job description

UNM Nuclear Engineering Department seeks a Research Assistant Professor to lead modeling, simulation, and experimental work on passive decay heat removal in fluoride-salt-cooled high-temperature reactors (FHRs) under molten salt leakage accident conditions. The position supports a funded research program spanning system-level modeling, transient multi-physics simulation, comparative analysis of ex-core cooling strategies (RCCS and PRACS), and validation against a reduced-scale salt leak test facility. The successful candidate will conduct independent research, contribute to proposals and publications, and help mentor graduate students. This is a full-time, grant-funded appointment with an initial one-year term and the possibility of renewal.
Key Responsibilities
Develop system-level models of FHR cores and reactor cavity cooling systems to capture transient decay heat generation and removal under salt-loss conditions, using MATLAB or Python.
Perform coupled neutronics, thermal-hydraulics, and burn-up analysis, and conduct CFD studies (RANS with conjugate heat transfer) to identify post-shutdown temperature hotspots.
Compare ex-core decay heat removal strategies (RCCS versus PRACS) using in-house models and/or MELCOR, and quantify removal efficiency, response time, and safety margins.
Support scaling analysis and the design, construction, and operation of a reduced-scale RCCS and salt facility, and use the experimental data to validate and refine the computational models.
Prepare technical reports, peer-reviewed publications, and proposal material, and present results to sponsors and at conferences.
Co-advise and train graduate and undergraduate researchers
