How much do nuclear reactor jobs pay per hour?
What are some of the key challenges faced by nuclear reactor operators during routine operations?
What is the difference between Nuclear Reactor vs Nuclear Power Plant Operator?
| Aspect | Nuclear Reactor | Nuclear Power Plant Operator |
|---|---|---|
| Role | Component of a power plant that contains the nuclear reactor core and facilitates nuclear reactions | Performs operational tasks to control and monitor the nuclear reactor and plant systems |
| Credentials | Typically requires nuclear engineering or related certifications, safety training | Requires reactor operator licensing, safety certifications, and technical training |
| Work Environment | Inside the reactor core or containment area, highly controlled and safety-focused | Control room and plant facilities, monitoring and adjusting reactor operations |
| Industry Usage | Part of a nuclear power plant, essential for energy generation | Operates and manages the reactor's functions within the plant |
In summary, a nuclear reactor is the core component where nuclear reactions occur, while a nuclear power plant operator manages and controls the reactor's operation within the plant. Both roles require specialized training and safety certifications, but they focus on different aspects of nuclear power generation.

Job description
Requisition Id 16831
Overview:
We are seeking a Nuclear Reactor Controller (Reactor Operator) for the High Flux Isotope Reactor (HFIR). Under limited supervision, this position is responsible for the safe and efficient operation of the HFIR in accordance with procedures and regulations, and maintenance of qualification through training.
A Nuclear Reactor Controller at the HFIR is a combination of all the naval nuclear ratings into one role; it is an appropriate position for all nuclear trained MMs, EMs, and ETs as well as personnel with commercial nuclear operations experience.
This position reports to a HFIR Shift Supervisor and resides in the HFIR Operations Section, Research Reactors Division, Neutron Sciences Directorate at Oak Ridge National Laboratory (ORNL).
Major Duties/Responsibilities:
- Obtain and maintain certification as a nuclear reactor controller (reactor operator).
- Follow good operational practices and requirements as required by DOE Order 422.1, Conduct of Operations.
- Maintain safe and efficient operation of the HFIR in accordance with procedures and regulations.
- Monitor plant parameters on a real time basis for assigned stations, analyzing trends and plant conditions.
- Involves operation of the reactor, the support systems for the reactor, water sampling, disassembly and reassembly of reactor components, refueling and defueling operations, tours and log taking throughout the plant and in the control room.
- Accomplish field work to support reactor operation, including functions as a waste generator and packager, operation of cranes and mobile equipment, inventorying and stocking materials, and other activities such as radiological decontamination.
- Function under high stress conditions where immediate decision making is required, and rapid actions taken with seamless coordination with other team members.
- Abiding by the principles of Safe Conduct of Research including being personally responsible for ensuring safe operations by raising safety concerns, using a questioning attitude, considering hazards for every task, and never stop learning.
- Additional tasks as assigned by management.
