How much do reactor jobs pay per hour?

As of Aug 19, 2026, the average hourly pay for reactor in the United States is $35.10, according to ZipRecruiter salary data. Most workers in this role earn between $20.19 and $36.54 per hour, depending on experience, location, and employer.

What is a reactor?

In the context of jobs, a 'Reactor' typically refers to a professional who operates and monitors nuclear reactors in power plants or research facilities. Their responsibilities include controlling reactor systems, ensuring safety protocols are followed, and responding to any operational anomalies. Reactor operators must be highly trained and licensed, as their work involves managing nuclear materials and protecting both people and the environment. They work closely with engineers and other technical staff to maintain efficient and safe reactor operations.

What are the key skills and qualifications needed to thrive as a nuclear reactor operator?

To thrive as a Nuclear Reactor Operator, you need a strong understanding of nuclear physics, engineering principles, and operational protocols, typically requiring a high school diploma or associate degree and completion of specialized training programs. Familiarity with reactor control systems, safety monitoring equipment, and a Nuclear Regulatory Commission (NRC) operator license are essential technical qualifications. Attention to detail, strong problem-solving abilities, and effective communication skills are crucial soft skills for this role. These skills and qualifications are vital to ensuring the safe, efficient, and regulatory-compliant operation of nuclear reactors.

What are some common challenges faced by reactor operators during daily operations?

Reactor operators frequently encounter challenges such as maintaining strict adherence to safety protocols while managing complex control systems. They must be vigilant to detect and respond quickly to abnormal readings or alarms, which requires strong attention to detail and the ability to stay calm under pressure. Additionally, operators often work in shifts and within tightly regulated environments, which can be physically and mentally demanding. Teamwork and clear communication with engineers and other operators are crucial to ensure safe and efficient reactor performance.

What is the difference between Reactor vs Technician?

AspectReactorTechnician
Required CredentialsTypically requires a degree in engineering or nuclear technology, along with specialized reactor operation certificationsUsually needs technical diploma or associate degree, with specific technical certifications
Work EnvironmentOperates in nuclear power plants or research reactors, following strict safety protocolsWorks in maintenance, troubleshooting, and support roles within industrial or nuclear facilities
Employer & Industry UsageCommonly employed by nuclear power plants, research institutions, and energy companiesEmployed across various industries including energy, manufacturing, and maintenance services

The main difference between a Reactor and a Technician lies in their roles and responsibilities. Reactors are specialized operators managing nuclear systems, requiring advanced certifications and working in high-security environments. Technicians support these operations through maintenance and technical support, often with less advanced credentials. Both roles are essential in the nuclear industry, but they differ in scope, training, and daily tasks.

How much do reactor operators get paid?

Reactor operators typically earn a median annual salary of around $80,000 to $100,000, depending on experience, location, and the specific facility. They often require specialized training, certifications, and adherence to strict safety protocols, with some positions offering additional shift differentials or overtime pay.

How to get a job at a nuclear reactor?

To work as a reactor operator or technician, candidates typically need a high school diploma or equivalent, followed by specialized training and certification from a recognized authority such as the Nuclear Regulatory Commission. Relevant skills include understanding nuclear physics, safety procedures, and operating control systems, often gained through an accredited training program or technical college. Prior experience in industrial or technical environments can also be beneficial.

Job description

About NANO Nuclear Energy

NANO Nuclear Energy is an advanced nuclear technology company developing next-generation microreactor systems that will help transform the future of clean, reliable, and resilient energy. Through the development of its KRONOS MMR™ Energy System, LOKI MMR™ Energy System, and ZEUS™ Solid Core Battery Reactor—advanced high-temperature gas‑cooled reactor (HTGR) technologies designed for applications including data centers, industrial operations, remote communities, and critical infrastructure—the company is advancing innovative nuclear solutions for a rapidly evolving energy landscape. NANO Nuclear has also submitted a Construction Permit Application (CPA) to the U.S. Nuclear Regulatory Commission (NRC) to support the planned deployment of the KRONOS MMR at the University of Illinois Urbana‑Champaign (UIUC), representing a significant milestone toward the commercialization of advanced nuclear technology.

Joining NANO Nuclear means contributing to pioneering technologies with the potential to redefine the nuclear industry while working alongside experts in engineering, science, and innovation. Our team operates in a collaborative, entrepreneurial environment where employees are encouraged to solve challenging technical problems and advance the materials technologies needed for next‑generation energy systems.

Position Overview

We are seeking a Nuclear Engineer, Reactor Physics who will be responsible for performing reactor physics analyses of the nuclear reactor power systems in development at Nano Nuclear Energy, Inc. The Nuclear Engineer will support core design enhancement, integrate customer and regulatory requirements into the reactor core design, and perform analysis and prepare documentation to support licensing of the reactor systems.

Responsibilities
  • Perform neutron and gamma radiation transport calculations to determine activation/dose rates, heating, and material damage effects, and establish radiation shielding requirements.
  • Design radiation shielding throughout the reactor system.
  • Perform criticality safety calculations.
  • Develop, verify, and validate computational tools for reactor multiphysics analysis.
  • Collaborate with engineering, operations & maintenance, safety analysis, and licensing teams.
  • Assist in training and mentoring junior team members.
  • Ensure compliance with nuclear regulations, licensing requirements, and company safety policies.
  • Contribute to the preparation of documents to enable licensing of Nano Nuclear Energy reactor systems.
  • Responsibilities may extend to other divisions of the business at times.
  • Bachelor’s degree in Nuclear Engineering or related field.
  • 7+ years (or M.Sc. and 5+ years) of relevant experience.
  • Strong Monte Carlo skills and strong understanding of reactor physics. Experience in reactor design, radiation shielding, and criticality safety desirable.
  • Strong programming skills in any language; Python is commonly used in this position.
  • Excellent problem‑solving and collaboration skills.
  • Nuclear software verification and validation experience is a plus.
