Overview
Naval Nuclear Operations roles involve keeping submarines and aircraft carriers running. Nuclear technicians, power plant operators, and subsystems specialists perform the complex technical functions at the core of sub and carrier capabilities, including operating propulsion plant machinery and maintaining electronic, propulsion, and weapons systems.
Responsibilities
There are three types of Nuclear Operations jobs for enlisted Sailors. Responsibilities depend on training, interests, and designation. All three ratings are eligible to receive bonuses for enlistment and re-enlistment.
* Machinist’s Mate Nuclear (MMN)
* Operate and maintain steam turbines and reduction gears used for nuclear ship propulsion and auxiliary machinery such as turbogenerators, pumps, and oil purifiers
* Maintain auxiliary machinery outside of main machinery spaces, such as electrohydraulic steering engines, elevators, refrigeration plants, air conditioning systems, and desalinization plants
* Operate and maintain compressed gas producing plants
* Perform duties in nuclear propulsion plants operating reactor control, propulsion, and power generation systems
* Electrician’s Mate Nuclear (EMN)
* Operate the ship's electrical power generation systems, lighting systems, electrical equipment, and electrical appliances
* Install, operate, adjust, maintain, inspect, test, and repair electrical equipment
* Maintenance and repair of related electronic equipment
* Troubleshoot electric breakers and circuits aboard nuclear-powered ships
* Electronics Technician Nuclear (ETN)
* Operate and maintain electronic systems that power the Navy’s nuclear reactor
* Calibrate control systems to generate power aboard submarines and aircraft carriers
* Be part of a watch team that enables the fission process to generate steam for propulsion
Work Environment
As an Enlisted Sailor in nuclear operations, you may work at sea or ashore, in a fast-paced environment aboard a nuclear-powered submarine or aircraft carrier.
Training & Advancement
NAVY NUCLEAR FIELD (NF) PROGRAM
After Boot Camp, Nuclear Operations personnel report to “A” School for rating-specific training, followed by advanced nuclear training.
“A” School for MMN
The MMN course in Charleston, SC provides basic knowledge of mathematics and the theory and operation of a steam power plant. It covers tools, test equipment, blueprints, rigging, and maintenance procedures, then proceeds to NNPS and NPTU.
“A” School for EMN
The EMN course in Charleston, SC covers mathematics and power distribution, AC/DC circuits, operation, troubleshooting, maintenance, and repair of electrical systems. Then NNPS and NPTU.
“A” School for ETN
The ETN course in Charleston, SC covers mathematics, electricity, electronics, solid-state devices, digital logic, instrumentation/control circuits, and schematic interpretation. Then NNPS and NPTU.
Naval Nuclear Power School (NNPS)
After A School, MMN, EMN, and ETN attend NNPS in Charleston, SC for theory and practical reactor knowledge, including reactor core principles and radiological control.
Nuclear Power Training Unit (NPTU)
Following NNPS, MMN, EMN, and ETN train at NPTU in Charleston, SC or Ballston Spa, NY to learn the fundamentals of a Naval nuclear power plant and the interaction of mechanical, electrical, and reactor subsystems. Training emphasizes safe operation of a complex Naval plant.
Promotion opportunities are available and competitive; training and experience can lead to credentialing and related opportunities.
Education Opportunities
Beyond credentials and certifications, Navy nuclear training can translate to up to 77 credit hours toward a degree through the American Council on Education. Additional opportunities include:
* Navy College Program and Tuition Assistance
* Post-9/11 GI Bill
Qualifications & Requirements
A high-school diploma or equivalent is required. Candidates must be U.S. citizens with successful completion of one year of Algebra and eligibility for security clearance. General qualifications may vary depending on current service status.
