This guide provides useful information that will help with your decision to become a Naval Nuclear Reactors Engineer during Fiscal Year 2025.
Naval Nuclear Reactor Engineers are Restricted Line Officers in the Navy who oversee all aspects of the Navy Nuclear Propulsion Program in Washington, D.C. The Navy Officer designator code for Naval Reactor Engineer is 1220.
As you will see, this program is very specialized and reserved for our country’s top talents.
Let us dive right in.
Nuclear Reactors Engineer Job Description
The most powerful energy on Earth needs the sharpest minds to keep it in check.
Nuclear Reactor Engineers don’t just design reactors. They study them, refine them, and keep them running on the ships and subs that define modern naval power. No room for error. No time for hesitation.
They don’t follow the standards—they set them. Pushing nuclear propulsion further. Locking down reactor safety. Leading cutting-edge research.
These engineers command the reactors that power the strongest fleet on the planet. And they don’t sit back—they chase down the hardest academic and technical challenges out there.
It’s not just engineering. It’s national security. It’s innovation. It’s teamwork that turns theory into action.
And while others in their field wait years for real responsibility, they take it on from day one.
Specific Responsibilities
Naval Reactors Engineers run the show when it comes to the Navy’s nuclear fleet. Ships, subs, shore-based prototypes, support facilities—if it’s nuclear-powered, they’re in charge.
The job pulls from every corner of engineering:
- Reactor and fluid system design
- Reactor physics
- Advanced materials
- Steam generators, pumps, valves—you name it
- Instrumentation and control systems
- Testing, shielding, chemistry, radiological controls
- Quality assurance, top to bottom
From concept to decommissioning, they oversee it all. Reactor design, fleet operations, refueling, dismantling warships—every step is under their watch. And they do it from Naval Reactors Headquarters in D.C., where the best and brightest engineers push nuclear propulsion forward.
The scale? Massive. Two Department of Energy labs. Two nuclear training sites. Nearly 100 nuclear-powered vessels. Six shipyards. Over 1,000 companies feeding into the program. It’s a high-speed, high-stakes environment where multiple projects run at once.
And while most engineers in the private sector wait years to get hands-on with critical systems, these officers jump in from day one.
What to Expect
Naval Reactors Headquarters. Washington, D.C. That’s where it all starts.
A small, elite team—just 500 people—overseeing the entire Naval Nuclear Propulsion Program. Every reactor. Every ship. Every operation. Start to finish.
The work is demanding. The stakes are high. But so is the reward. You’ll take on critical tasks alongside the best minds in nuclear engineering. Not just theory: real-world application.
It’s a path that moves fast. From post-grad-level academic study to hands-on training with prototype reactors. You’ll visit nuclear-powered vessels, inspect operations firsthand, and work with top industry leaders. No uniform required, but the mission is clear.
The experience? Unmatched. The impact? Unquestionable. The work? Classified.
Precision and discretion aren’t suggestions—they’re requirements.
Post-Service Opportunities
Nuclear Navy experience builds a different kind of mind—sharp, disciplined, but flexible enough to tackle problems no one else can crack.
These officers don’t just follow instructions. They lead. Whatever the challenge, whatever the mission, they step up.
The Navy takes raw intellect, character, and drive and forges it into real-world skill. Technical mastery. Leadership under pressure.
After four to five years, doors open.
High-level research, teaching, consulting—leadership roles in and out of uniform.
Civilian opportunities? Plenty. Many pay more. But few match the depth of experience gained here.

NUPOC Interview
All students who apply to the Navy Nuclear Propulsion Officer Candidate (NUPOC) program are subjected to a stringent screening procedure before being chosen for a personal interview with the Director of Naval Reactors in Washington, D.C.
The first portion of the interview involves technical questions from calculus, physics, and other technical disciplines.
The bulk of the questions are from calculus and physics, but you may be questioned about other areas in your major as well.
This section of the interview usually lasts 30–40 minutes and includes two to four key questions every session.
The second round of the interview procedure included meeting with the Admiral in charge of the Naval Nuclear Propulsion program.
During this interview, the Admiral will go through your transcripts and technical interview assessments, as well as analyze your communication skills, interests, and enthusiasm for the program.
All potential Nuclear Officers are hand-picked by the Admiral.
VIP Tour
If you are a qualifying Nuclear Propulsion Officer candidate, the Navy provides a two-day VIP excursion to immerse you in this environment.
You will get the chance to explore the flight deck of an aircraft carrier or the torpedo chamber of a submarine. Interact with and question existing and potential Officers.
You will also learn about the Navy’s long history and its nuclear program.
This is your opportunity to see firsthand what it is like to start your career as a Nuclear Officer in the Navy.
Navy Nuclear Reactors Officer Training
Following graduation from college, the formal training procedure for becoming an Officer in the Naval Nuclear Propulsion program begins.
Officer Development School (ODS) — a five-week training in Newport, RI that gives a complete and intensive introduction to the duties of becoming a Navy Officer – is the first step for anyone interested in becoming a Naval Reactors Engineer.
Following the conclusion of ODS, newly commissioned Officers go to the advanced training that is at the heart of Navy Nuclear Propulsion.
Naval Reactors Engineers may anticipate to spend the next five years in charge of the Navy’s shore-based prototypes, shipboard nuclear power plants, and nuclear propulsion support facilities.
The rigorous training they get prepares them to work alongside some of the country’s finest and brightest technical specialists.
Preliminary Training: Naval Reactors Headquarters (NR)
Officers will spend the first four to five months of their careers at the Naval Reactors Headquarters in Washington, D.C., completing preparatory training.
This is followed by around two weeks of training at one of the Navy’s land-based prototypes in either Charleston, SC, or Albany, NY.
Naval Reactors Training Program (NRTP)
The next phase is a six-month postgraduate-level study in nuclear engineering at the Bettis Atomic Power Laboratory in Pittsburgh, PA, via the Bettis Reactor Engineering School.
Staff Assignment: Naval Reactors Headquarters (NR)
Following Naval Reactors Training, Naval Reactors Engineers are assigned to the group in charge of administering all technical elements of the Naval Nuclear Propulsion program, including designing, authorizing, and verifying the design, operation, and maintenance of approximately 100 nuclear reactors.
Engineers begin in a subordinate position, reporting to a supervisor, and quickly ascend to take on increased responsibility.
