This is where the highly trained operators run the plant. Usually there are three operators in the control room, supervised by two shift supervisors. The operators' job is somewhat like that of a commercial jet pilot. Most of their time is spent monitoring a machine that is running smoothly. However, they are highly trained so they can quickly and effectively deal with any abnormal conditions.
Numerous gauges tell operators what's going on in the plant.
Also, there are backlit panels and associated alarms that immediately notify operators if something has changed. All operators are trained in detailed, written procedures that guide their response to unusual conditions. Even when the plant is shut down for refueling and maintenance, all major activities inside the plant are coordinated through the control room. All employees and visitors must pass through access control before entering any of the radiological areas of the plant such as the turbine floor or the reactor building. Here, visitors are issued dosimeters that will measure any radiation exposure they might receive while in the radiologically-controlled areas of the plant.
