What you earn and what it costs to get there.
Typical
$133,970
First job
$92,960
Senior or principal
$196,290
The national median is $133,970 a year, and the bottom tenth start near $92,960. This is one of the highest paid engineering fields in the federal wage survey, mostly because it is small and the safety stakes are high.
About $93,000 to $105,000
First engineering job straight out of a four-year degree
Utilities, national laboratories and reactor vendors all start in roughly the same place. Federal jobs at the nuclear regulator pay on a government scale that starts lower and has excellent benefits.
$196,290 a year
What the highest paid tenth earn
That tier is senior reactor engineers, licensing specialists who know the rules inside out, and people running projects at reactor vendors. A master's degree helps to get there and is common in this field.
Tuition, fees, exams and kit. Not rent, food or travel
The low end is two years at a community college transferring into a public university in your own state, about 11,000 dollars a year for the last two, plus the Fundamentals of Engineering exam at roughly 175 dollars. The high end is the full four years at in state prices plus a master's degree you pay for yourself, along with the later Principles and Practice exam and the state application fee. Many master's students are funded by a research assistantship instead, which costs nothing and pays a stipend, so the high end is avoidable. Going out of state or private at 35,000 to 60,000 dollars a year would push this well past 200,000 dollars, which is why almost everyone in this field uses their own state's university.
Fill out the FAFSA (Free Application for Federal Student Aid). Engineering departments also hand out a lot of scholarships, and the American Nuclear Society runs its own for students in the field.
Pensions still exist here
Utilities and federal employers are among the last places in the country offering a real defined benefit pension.
Employer paid graduate school
Utilities and national laboratories frequently pay for a master's degree while you work.
Very stable employment
A reactor runs for 40 to 80 years and needs engineers for all of it. Layoffs are rare compared with tech.
Security clearance
Getting one takes months and is worth money for the rest of your career.
The exact path from high school to qualified.
Four years to your first job, eight to a full professional license if you want one.
High school
Grades 11 and 12
Physics, chemistry and as much math as your school offers. Calculus before college is a real advantage.
Bachelor's degree
4 years
Nuclear engineering, or mechanical or electrical engineering with a nuclear minor. Choose a program accredited by ABET (the national accreditor for engineering degrees).
Internship or co-op
Summers
A summer at a plant, a reactor vendor or a national laboratory. This is how almost everyone gets hired.
FE (Fundamentals of Engineering) exam
Final year
Sit it in your final year while the material is fresh. It makes you an engineer in training.
Four years of engineering work
4 years
Then you are eligible for the professional exam. There is a nuclear version of it among the twenty or so offered.
PE (Principles and Practice of Engineering) licensure
After 4 years of work
Optional in this field but it raises your pay and lets you sign off work in your own name.
Physics
This is applied nuclear physics. If you do not enjoy it at 17 you will not enjoy it at 27.
Calculus
Heat transfer and reactor behavior are differential equations. Starting ahead saves you a hard first year.
Chemistry
Fuel, coolant chemistry and waste handling are chemistry problems.
Computer science
Modern reactor work is simulation. Knowing Python before you arrive puts you ahead.
Because so few schools offer the degree, plenty of nuclear engineers start as mechanical or electrical engineers and specialize on the job.
You do not need a license to work as a nuclear engineer for a utility or a vendor. Most never get one. A professional engineer license is issued state by state after an accredited degree, the fundamentals exam, four years of experience and a further exam, and there is a nuclear version of that second exam. The body that actually governs this industry is the Nuclear Regulatory Commission, which licenses the plants themselves and the operators who sit at the controls. A large slice of nuclear engineering work is proving to that agency, on paper, that something is safe.
Universities with research reactors
Penn State runs the Breazeale Reactor, the first and longest operating licensed research reactor in the country, and students use it.
Big state engineering schools
Programs in states with nuclear plants tend to have the strongest industry links and the best internships.
Mechanical or electrical plus a minor
A common route, and it keeps your options open if you change your mind.
The Navy
The naval nuclear propulsion program trains operators and engineers, and its graduates are hired straight into the civilian industry.
Things you don't need, but that help.
Reactor licensing
Writing and defending safety cases to the federal regulator. Unglamorous, essential, and very well paid.
Small modular reactors
The new designs everyone is funding. Higher risk employers, more interesting work.
Medical isotopes
Reactors and accelerators that make the tracers used in hospital scans and cancer treatment.
Decommissioning and waste
Taking old plants apart safely. Decades of guaranteed work in it.
A clean record
Plant access and security clearance both involve a background check. Plan accordingly.
Simulation and coding skills
Most design work now happens in software before anything is built.
Patience with paperwork
In this industry the documentation is the work. If that idea annoys you, look at another branch of engineering.
Willingness to live near a plant
Reactors are not in city centers. Neither are most of the jobs.
The federal outlook for this occupation is below average, with employment expected to decline, because the existing reactor fleet is not growing quickly and each plant needs a fixed number of engineers. At the same time there is real money going into new reactor designs and the national laboratories. Both things are true. The safe read is that this is a stable, well paid niche rather than a booming one, and that a degree in mechanical or electrical engineering with a nuclear focus gives you somewhere to go if the new projects stall.
Day to day, pros and cons, where you'd work.
Most of it is at a desk. You run a simulation of how the core behaves if a pump fails, compare the result against the limits in the plant's safety case, and write it up in a document that will be read line by line by a regulator. Mid-morning there is a meeting about a component that a supplier wants to substitute, and the answer depends on a standard from 1998. In the afternoon you go into the plant, in coveralls with a dose badge, to look at the thing you have been modeling. It is quieter than you expect.
The good
The hard parts
Things people don't tell you.
The United States runs the largest fleet of power reactors in the world. The Department of Energy says they generate nearly 20 percent of the country's electricity and almost half of its clean energy.
Penn State's Breazeale Reactor was the first licensed nuclear research reactor in the country and is still the longest operating one. Undergraduates do experiments on it.
The national engineering exam board offers more than twenty different professional exams, and nuclear is one of them. Most nuclear engineers never take it, because industry work does not require a license.
The federal outlook for nuclear engineers is below average, with employment expected to decline. It is a well paid field, and a small and slow moving one. Go in with your eyes open.
Last checked September 2026. Pay figures are typical full-time annual amounts in United States dollars, based on Bureau of Labor Statistics wage data and published pay scales. They vary by state, employer and experience. Tuition is for in-state students at public schools unless the card says otherwise.
