The median pay is about $133,970 a year. Across everyone in the job it runs from about $92,960 at the lower end to about $196,290 at the upper end. The source is listed under Sources at the end of this page.

$33,000 to $120,000 all in for tuition, fees, exams and kit. Living costs are not counted.
No. There is no license to hold, though many employers still ask for training or a certificate.

The national median is $133,970 a year, and the bottom tenth earn $92,960 or less. That is the fourth highest median of the engineering occupations in the survey, behind computer hardware, petroleum and aerospace engineers.
$108,690 a year
25% of nuclear engineers earn this or less
This covers everyone in the job, not only beginners, because the survey publishes no separate starting figure. Federal jobs at the nuclear regulator pay on a published government scale and come with excellent benefits.
$163,630 a year or more
25% of nuclear engineers earn this or more
The survey does not say who makes up the top quarter. A master's degree is common in this field.
Roughly, all in
$33,000 to $120,000
Tuition, fees, exams and kit. Not rent, food or travel
The low end is two years at a community college at about $4,150 a year, transferring into a public university in your own state at about $12,000 a year for the last two, plus the Fundamentals of Engineering exam at $225. 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 a year would push this well past $200,000, 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 offering a pension that pays a set monthly amount for life, rather than only a savings account.
Employer paid graduate school
Utilities and national laboratories frequently pay for a master's degree while you work.
Very stable employment
The average American reactor is about 44 years old and still running, and a plant needs engineers for all of its life. Layoffs are rare compared with tech.
Security clearance
Getting one takes months, and it stays useful 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, offered once a year.
PE (Principles and Practice of Engineering) licensure
After 4 years of work
Optional in this field, but it 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 and essential.
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 little or no change in employment from 2025 to 2035, with about 800 openings a year. The existing reactor fleet is not growing quickly. 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 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 nuclear power plants in the world: 94 reactors at 54 plants, which made 19% of the country's electricity in 2024, according to the Energy Information Administration.
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 oldest operating American reactor, Nine Mile Point Unit 1 in New York, started in December 1969. The newest, Vogtle Unit 4 in Georgia, started in April 2024. The average reactor is about 44 years old.
