Nuclear Operations

Operate reactor control, propulsion and power generation systems in the nuclear propulsion plants aboard submarines as a nuclear-trained Machinist’s Mate, Electrician’s Mate or Electronics Technician.
Responsibilities in the Navy Nuclear operations area depend upon the job rating or specialty you are in.

Machinist Mate (MM)
MMs operate and maintain steam turbines and reduction gears used for ship propulsion and auxiliary machinery such as turbogenerators, pumps and oil purifiers. They also maintain auxiliary machinery outside of main machinery spaces, such as electrohydraulic steering engines and elevators, refrigeration plants, air conditioning systems and desalinization plants. They may also operate and maintain compressed gas producing plants. Nuclear-trained MMs perform duties in nuclear propulsion plants operating reactor control, propulsion and power generation systems.

Electrician’s Mate (EM)
EMs are responsible for the operation of a ship's electrical power generation systems, lighting systems, electrical equipment and electrical appliances. The duties include installation, operation, adjustment, routine maintenance, inspection, test and repair of electrical equipment. EM's also perform maintenance and repair of related electronic equipment. Nuclear-trained EMs perform duties in nuclear propulsion plants operating reactor control, propulsion and power generation systems.

Electronics Technicians (ET)
ETs are responsible for electronic equipment used to send and receive messages, computer information systems, long range radar, and calibration of test equipment. They maintain, repair, calibrate, tune, and adjust electronic equipment used for communications, detection and tracking, recognition and identification and navigation. Nuclear-trained ETs perform duties in nuclear propulsion plants operating reactor control, propulsion and power generation systems.
