Navy Enlisted Nuclear Field Rating Descriptions and Qualifications
The Navy’s Nuclear Field (NF) program offers extensive training as nuclear propulsion plant operators and technicians to young men and women with aptitude in mathematics and science. The standards for selection for enlistment in the Navy’s NF program are high. People applying for NF training must be dedicated to pursuing the challenge this highly technical field offers. Applicants should be mature, responsible, and capable of working well under pressure.
Note: NF is not an actual rating, but rather a specialized enlistment program.
NF candidates must be U.S. citizens. Candidates must also not have reached their 25th birthday by the time they enter active duty (ship out to basic training). However, age-waivers will be considered on a case-by-case basis. Applicants must be a high school diploma graduate (not GED) with successful completion of one year of algebra, and able to meet Secret security clearance requirements.
Active duty obligation is six years. Applicants must enlist for four years and concurrently execute an agreement to extend their enlistment for 24 months to accommodate the additional training involved.
Personnel selected for nuclear training enter the Navy in pay grade E-3. Accelerated advancement to pay grade E-4 is authorized after personnel completes all advancement-in-rate requirements (to include minimum time in rate) and “A” School, provided eligibility in the NF Program is maintained.
Enlistment and reenlistment bonuses in addition to Navy salary, special duty assignment pay, and allowances for food and housing are available. Those who volunteer and are selected to serve on nuclear submarines (men only) are eligible for added submarine duty incentive pay from the day they graduate from nuclear training.
Three Navy job specialties, called “ratings,” are included in the NF community: Machinist’s Mate (MM), Electrician’s Mate (EM), and Electronics Technician (ET). The rating in which an NF candidate is trained is determined at the Recruit Training Center (boot camp).
Nuclear-trained MMs, EMs, and ETs perform duties in nuclear propulsion plants operating reactor control, propulsion, and power generation systems. The character of NF jobs is mentally stimulating and offers career growth. The NF provides opportunities to work closely with specialists in the nuclear, technology, and engineering fields.
The educational opportunities available to the nuclear-trained Sailor range from college-level classes in physics, chemistry, mathematics, electrical engineering, and thermodynamics to nuclear engineering training in nuclear power plant design, construction, instrumentation, and operations. The American Council on Education (ACE) has verified the extensive nature and unsurpassed quality of the Navy’s nuclear propulsion training program by recommending up to 77 semester hours of college credit.
After recruit training, NF candidates report to the NF “A” School in Charleston, SC, for technical training in their specific ratings. They then attend Nuclear Power School (NPS) in Charleston, SC, where they learn theory and practical application of nuclear physics and reactor engineering. Following NPS, candidates begin prototype training in their rating specialty at one of two Nuclear Power Training Units (NPTUs). After nuclear power training, NF Sailors are designated nuclear propulsion plant operators.
They may be assigned to modern nuclear-powered aircraft carriers or volunteer for submarine service (men only).
ASVAB Score: VE+AR+MK+NAPT = 290 (with minimum 50 NAPT score) or AR+MK+EI+GS+NAPT = 290 (with minimum 50 NAPT score) or VE+AR+MK+MC = 252 (No NAPT required) or AR+MK+EI+GS = 252 (No NAPT required).
Security Clearance: (SECRET) required. Must be a U.S. Citizen. At least 17 years of age but not have reached 25th birthday by active duty date (waivers on a case basis). Police Record Checks required. Any offense (except minor traffic) in DEP requires a waiver. Any history of drug use (including marijuana) requires a waiver. Must provide complete transcripts of high school records. Must have completed one full year of algebra in HS or college.

Nuclear Field Statement of Understanding
Active Duty Service Obligation: Six years, accomplished by a four-year enlistment, plus a two-year extension of enlistment for training in the Nuclear Field.
Rating Assignment: During recruit training, personnel not already guaranteed Machinist's Mate training will be selected for training in one of the following ratings: Machinist's Mate, Electrician's Mate, or Electronics Technician. This decision will be based on the needs of the service, test score profile, and, so far as possible, upon the personal desire of the individual.
Challenging Program: The training program consists of three stages: 1) four to six months of intensive classroom instruction at Nuclear Field Class "A" school; 2) six months of intensive classroom instruction in mathematics, physics, and basic engineering sciences at Nuclear Power School; and 3) six months of rigorous operational training and qualification on a nuclear reactor prototype plant. Nuclear Field personnel must demonstrate good academic performance in all phases of training. Markedly inferior performance, including very low passing final grades or an obvious lack of effort in any training phase, may result in disenrollment from the Nuclear Field program.
Duty Assignment: The Nuclear Field program trains personnel for nuclear submarines (men only) and nuclear surface ship assignments. No promise can be made regarding the type of duty assigned.
Automatic Advancement: Personnel in the Nuclear Field program will be enlisted in pay grade E-3. Advancement to pay grade E-4 is authorized only after personnel complete all advancement-in-rate requirements (to include minimum time in rate) and Class "A" School, provided eligibility in the Nuclear Field program is maintained. If Nuclear Field Class "A" School training is not completed, the member will be administratively reduced to E-2 or E-1, depending on the member's time in rate at the date of disenrollment.
Upon acceptance of automatic advancement to pay grade E-4, the member will be obligated for 12 months of the two-year extension, in addition to the four-year enlistment, regardless of whether or not advanced training is completed.
Termination of training: Having once volunteered, a Nuclear Field recruit will not be dropped for reason of non-volunteering. Determination of additional obligated service required following disenrollment from the Nuclear Field program will be in accordance with MILPERSMAN 1160-080.
Character: Personnel in the Nuclear Field program must continually demonstrate by their professional performance, academic achievement and military behavior that they possess the ability, maturity, personal reliability, and integrity to complete the demanding training program and serve successfully as nuclear propulsion plant operators in the fleet. Consequently, any event which cast serious doubt on the member's ability to continually satisfy these high standards of conduct may result in that member's disenrollment from the Nuclear Field program.
Drug Abuse: Entry into or continuation in the Nuclear Field program will be denied to any individual who has been convicted of, or who is identified as having, illegally, wrongfully, or otherwise improperly used marijuana, narcotics, inhaled substances, or other controlled substances, or illegally or wrongfully possessed or engaged in the sale of the same. This restriction applies prior to and after entry into active service, with the exception of waivers granted for experimental use of marijuana prior to entry into active duty.
Special Pay: Personnel in the Nuclear Field who have completed Nuclear Power Training and been awarded a nuclear NEC receive Special Duty Assignment Pay (SDAP) in accordance with applicable NAVADMIN. Personnel assigned to submarine duty are eligible for submarine duty incentive pay, according to current pay tables.
College Credit: College Credit is not granted by the Navy for courses studied at Nuclear Power School.
Department of Energy License to Operate a Reactor: A license from the Department of Energy to operate a reactor plant is not granted by virtue of this training.
Advanced Education: While Nuclear Field training may enhance a candidate’s suitability for Navy advanced educational or officer candidate programs, no promise or guarantee of selection nor eligibility for any such program should be inferred.
