WebFirst, water is used to convert thermal energy from the core to turn the steam turbines. Water passes by the core, absorbs the thermal energy creating steam, which in turn spins the turbines. These turbines are responsible for generating the electricity that is carried onto the regional power grid. WebDuring normal reactor operation, the level of the water in the reactor is controlled by a feedwater controller which receives inputs from reactor vessel water level, steam mass flow rate, and feedwater mass flow rate transmitters as shown in Figures 3.3-1 and 3.3-2.
