Occupation
Nuclear power reactor operator
Nuclear power reactor operators control the reactor and its supporting systems from a licensed control room, holding reactivity, coolant flow, and power output inside strictly defined limits. The role is built around procedures, verification, and peer checking rather than improvisation. Training, requalification, and simulator testing continue for as long as someone holds the position.
