Nuclear-trained MMs 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.
