How much do full time reactor physics jobs pay per hour?
As of Jun 16, 2026, the average hourly pay for full time reactor physics in the United States is $20.06, according to ZipRecruiter salary data. Most workers in this role earn between $12.50 and $25.48 per hour, depending on experience, location, and employer.
What is the difference between Full Time Reactor Physics vs Reactor Operations Technician?
| Aspect | Full Time Reactor Physics | Reactor Operations Technician |
|---|---|---|
| Required Credentials | Advanced degrees in nuclear engineering or physics, certifications in reactor safety | Technical diploma or associate degree, on-the-job training |
| Work Environment | Research facilities, nuclear power plants, analytical labs | Control rooms, plant floors, operational settings |
| Employer & Industry Usage | Research institutions, nuclear power industry, government agencies | Nuclear 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.
